Indicators and mechanisms of stability and resilience to climatic and landscape changes in a remnant calcareous grassland

When considering the development of conservation strategies for threatened plant communities it is crucial to understand their resilience to environmental change, taking into account current decline and the occurrence of further habitat fragmentation and climatic changes. Many recent works describe resilience character and elements, but there is little focus on the metrics and indices that describe elements of stability and specific resistance or resilience over the community composition matrix. Communities with strong niche selection might be restricted to specific resistance strategies to cope with environmental changes. This would result in a community at greater risk from increasing fragmentation and climatic changes.In a 35 years survey of relic calcareous grasslands, we looked at measures to identify the resilience mechanisms for stability in the presence and abundance of species. We used techniques of partitioning of temporal beta diversity in nestedness and turnover components, analysis of functional strategy changes and dissimilarity analysis to detect changes in between⿿plot diversity and exchanges.Contrary to expectations, we observe strong resilience with different stabilizing mechanisms both at plot level and exchanges between plots. At the scale of our grassland complex, response diversity and environmental stochasticity allow for the maintenance of high biodiversity under natural perturbations and gradual human-induced environmental changes. This highlights the importance of dispersal, recruitment dynamics and microsite diversity.Community resilience is more than just the sum of species resilience strategies; adaptive management strategies need more emphasis on the variability of conditions, as this can enable or disrupt important community resilience mechanisms.     

Predicting Pasture and Forest Landowner Intention to Create Early Successional Habitat

As human land uses expand across the landscape, the management practices of private landowners are an essential part of effective conservation. Early successional habitats (ESH) and the species that depend on them are a priority in the eastern United States, and efforts to create ESH on private lands has primarily focused on forest landowners and timber harvests. Private pasture lands in a forested landscape present an additional opportunity to create and maintain ESH, yet our understanding of landowner values and attitudes about management strategies in pastures is lacking. To address this, we surveyed private landowners in 5 Virginia counties who own ≥10.1 ha at >610 m elevation (n = 503). Our primary objective was to understand how a variety of factors such as landowner values, past experience with habitat management, and perceived barriers to carrying out habitat management are associated with private landowner intention to carry out 7 ESH management strategies (i.e., reduced mowing, reduced grazing, timber harvests within forest, timber harvests at a field-forest border, prescribed fire, use of machinery, and use of herbicides to control invasive species) for the benefit of wildlife in the next 5 years. We used boosted regression trees to determine which factors best predicted the intention to carry out each management strategy. We were able to predict accuracy >75% of the time for landowner intention to engage in open pasture and timber management strategies. Landowner values were not consistent across the different management strategies; landowners likely to reduce mowing or grazing valued ecological aspects of their land (e.g., pollinator habitat, water quality), whereas landowners likely to harvest timber valued hunting and revenue. Past experience with wildlife management was the strongest predictor of likelihood to reduce mowing and grazing. Our results suggest that expanding outreach efforts to include pasture management options would engage a broader set of landowners in creating ESH, especially if such efforts highlighted the benefits to pollinator species, water quality, and enhanced opportunities for hunting and other types of recreation. © 2021 The Wildlife Society.     

From Metaphor to Measurement: Resilience of What to What?

Resilience is the magnitude of disturbance that can be tolerated before a socioecological system (SES) moves to a different region of state space controlled by a different set of processes. Resilience has multiple levels of meaning: as a metaphor related to sustainability, as a property of dynamic models, and as a measurable quantity that can be assessed in field studies of SES. The operational indicators of resilience have, however, received little attention in the literature. To assess a system's resilience, one must specify which system configuration and which disturbances are of interest. This paper compares resilience properties in two contrasting SES, lake districts and rangelands, with respect to the following three general features: (a) The ability of an SES to stay in the domain of attraction is related to slowly changing variables, or slowly changing disturbance regimes, which control the boundaries of the domain of attraction or the frequency of events that could push the system across the boundaries. Examples are soil phosphorus content in lake districts woody vegetation cover in rangelands, and property rights systems that affect land use in both lake districts and rangelands. (b) The ability of an SES to self-organize is related to the extent to which reorganization is endogenous rather than forced by external drivers. Self-organization is enhanced by coevolved ecosystem components and the presence of social networks that facilitate innovative problem solving. (c) The adaptive capacity of an SES is related to the existence of mechanisms for the evolution of novelty or learning. Examples include biodiversity at multiple scales and the existence of institutions that facilitate experimentation, discovery, and innovation. Received 20 March 2001; accepted 6 June 2001.     

The Use of Discontinuities and Functional Groups to Assess Relative Resilience in Complex Systems

It is evident when the resilience of a system has been exceeded and the system qualitatively changed. However, it is not clear how to measure resilience in a system prior to the demonstration that the capacity for resilient response has been exceeded. We argue that self-organizing human and natural systems are structured by a relatively small set of processes operating across scales in time and space. These structuring processes should generate a discontinuous distribution of structures and frequencies, where discontinuities mark the transition from one scale to another. Resilience is not driven by the identity of elements of a system, but rather by the functions those elements provide, and their distribution within and across scales. A self-organizing system that is resilient should maintain patterns of function within and across scales despite the turnover of specific elements (for example, species, cities). However, the loss of functions, or a decrease in functional representation at certain scales will decrease system resilience. It follows that some distributions of function should be more resilient than others. We propose that the determination of discontinuities, and the quantification of function both within and across scales, produce relative measures of resilience in ecological and other systems. We describe a set of methods to assess the relative resilience of a system based upon the determination of discontinuities and the quantification of the distribution of functions in relation to those discontinuities.     

External shocks,agent interactions,and endogenous feedbacks — Investigating system resilience with a stylized land use model

Dynamics of coupled Social-Ecological Systems (SES) result from the interplay of society and ecology. To assess SES resilience, we constructed an Agent-Based Model (ABM) of a land use system as a stereotypical example of SES and investigated how resilience of the represented system is affected by both external disturbances and internal dynamics. The model explicitly considered different aspects of resilience in a framework derived from literature, which includes “resilience to”, “resilience of”, “resilience at”, “resilience due to”, and “indicators of resilience”. External disturbances were implemented as shocks in crop yields. Internal dynamics comprised of two types of social interaction between agents (learning and cooperation), an ecological feedback of soil depletion and an economic feedback of agglomeration benefits. We systematically varied these mechanisms and measured indicators that reflected spatial, social, and economic resilience. Results showed that (1) internal mechanisms increased the ability of the system to recover from external shocks, (2) feedbacks resulted in different regimes of crop cultivation, each with a distinctive set of functions, and (3) resilience is not a generic system property, but strongly depends on what system function is considered. We recommend future studies to include internal dynamics, especially feedbacks, and to systematically assess them across different aspects of resilience.     

Agroecosystem resilience is modified by management system via plant–soil feedbacks

Designing resilient cropping systems is essential to sustain agricultural production in the face of changing environmental and social pressures. However, the extent to which changes in farm management systems could alter resistance and resilience is largely unknown, especially in response to climate change. Plant and soil microbial community interactions are a vital component of functioning and resilient agroecosystems. The aim of our study was to use winter wheat (Triticum aestivum L.) and pea (Pisum sativum L.) plant–soil feedbacks (i.e. plant species-specific effects on soil biota and their impacts on subsequent plant growth) as a metric of system resilience and resistance to climate variability in three different farming management systems: 1) a chemical no-till system, 2) an USDA-certified organic system reliant on tillage and 3) an USDA-certified organic system that included sheep grazing with the overall goal of minimizing tillage intensity. Climate conditions soil experienced were ambient, warmer, and warmer and drier and were manipulated in the field using open-top chamber and rain-out shelters. Plant–soil feedbacks were negative for wheat and positive for pea but varied among farming management systems but were less sensitive to climate conditions. Plant–soil feedbacks were lower in magnitude in the tilled organic system indicating more resistance to the accumulation of pathogenic soil microbiota resulting from repeated cropping of wheat. However, recovery was lower when the crop was pea in the tilled organic indicating slower recovery and less resilience. Results indicate that while increases in crop diversity may promote more resilient agroecosystems, farming management will affect agroecosystem resilience.     

An Analysis of Overstory Tree Canopy Cover in Sites Occupied by Native and Introduced Cottontails in the Northeastern United States with Recommendations for Habitat Management for New England Cottontail

The New England cottontail (Sylvilagus transitionalis) is a high conservation priority in the Northeastern United States and has been listed as a candidate species under the Endangered Species Act. Loss of early successional habitat is the most common explanation for the decline of the species, which is considered to require habitat with dense low vegetation and limited overstory tree canopy. Federal and state wildlife agencies actively encourage landowners to create this habitat type by clearcutting blocks of forest. However, there are recent indications that the species also occupies sites with moderate overstory tree canopy cover. This is important because many landowners have negative views about clearcutting and are more willing to adopt silvicultural approaches that retain some overstory trees. Furthermore, it is possible that clearcuts with no overstory canopy cover may attract the eastern cottontail (S. floridanus), an introduced species with an expanding range. The objective of our study was to provide guidance for future efforts to create habitat that would be more favorable for New England cottontail than eastern cottontail in areas where the two species are sympatric. We analyzed canopy cover at 336 cottontail locations in five states using maximum entropy modelling and other statistical methods. We found that New England cottontail occupied sites with a mean overstory tree canopy cover of 58% (SE±1.36), and was less likely than eastern cottontail to occupy sites with lower overstory canopy cover and more likely to occupy sites with higher overstory canopy cover. Our findings suggest that silvicultural approaches that retain some overstory canopy cover may be appropriate for creating habitat for New England cottontail. We believe that our results will help inform critical management decisions for the conservation of New England cottontail, and that our methodology can be applied to analyses of habitat use of other critical wildlife species.     

Preparing Wildlife for Climate Change: How Far Have We Come?

Global biodiversity is in unprecedented decline and on-the-ground solutions are imperative for conservation. Although there is a large volume of evidence related to climate change effects on wildlife, research on climate adaptation strategies is lagging. To assess the current state of knowledge in climate adaptation, we conducted a comprehensive literature review and evaluated 1,346 peer-reviewed publications for management recommendations designed to address the consequences of climate change on wildlife populations. From 509 publications, we identified 2,306 recommendations and employed both qualitative and quantitative methods for data analysis. Although we found an increase in the volume and diversity of recommendations since 2007, a focus on protected areas (26%, 596 of 2,306 recommendations) and the non-reserve matrix (12%, 276 of 2,306 recommendations) remained prominent in the climate adaptation literature. Common concepts include protected areas, invasive species, ecosystem services, adaptive management, stepping stones, assisted migration, and conservation easements. In contrast, only 1% of recommendations focused on reproduction (n = 26), survival (n = 14), disease (n = 26), or human-wildlife conflict (n = 24). Few recommendations reflected the potential for local-scale management interventions. We demonstrate limited advancement in preparing natural resource managers in climate adaptation at local, management-relevant scales. Additional research is needed to identify and evaluate climate adaptation strategies aimed at reducing the vulnerability of wildlife to contemporary climate change. © 2020 The Wildlife Society.     

气候变化背景下野生动物脆弱性评估方法研究进展

The effect of sea-level rise on coastal geomorphology

Sustainable management of coastal resources requires that future generations of people and wildlife enjoy an ongoing and equitable level of environmental quality ( Crooks & Turner 1999 ). The UK coast is, however, difficult to manage, being inhabited by a population with assets entrenched behind old flood defences and under threat from the combined risks of flooding and habitat change associated with rising sea-levels. Adopting a static policy approach towards sea-level rise conflicts with sustaining a dynamic coastal system that responds to perturbations via sediment movement and long-term evolution. At many locations maintaining a resilient coast demands the availability of space and sediments, but both are in short supply. Future management should incorporate adaptive measures, including strategic large-scale coastal floodplain reactivation, to support a resilient geomorphic response to sea-level rise. Management decisions will have major implications for coastal waterbirds.

Robustness and management adaptability in tropical rangelands: a viability-based assessment under the non-equilibrium paradigm

Rangelands provide the main forage resource for livestock in many parts of the world, but maintaining long-term productivity and providing sufficient income for the rancher remains a challenge. One key issue is to maintain the rangeland in conditions where the rancher has the greatest possibility to adapt his/her management choices to a highly fluctuating and uncertain environment. In this study, we address management robustness and adaptability, which increase the resilience of a rangeland. After reviewing how the concept of resilience evolved in parallel to modelling views on rangelands, we present a dynamic model of rangelands to which we applied the mathematical framework of viability theory to quantify the management adaptability of the system in a stochastic environment. This quantification is based on an index that combines the robustness of the system to rainfall variability and the ability of the rancher to adjust his/her management through time. We evaluated the adaptability for four possible scenarios combining two rainfall regimes (high or low) with two herding strategies (grazers only or mixed herd). Results show that pure grazing is viable only for high-rainfall regimes, and that the use of mixed-feeder herds increases the adaptability of the management. The management is the most adaptive with mixed herds and in rangelands composed of an intermediate density of trees and grasses. In such situations, grass provides high quantities of biomass and woody plants ensure robustness to droughts. Beyond the implications for management, our results illustrate the relevance of viability theory for addressing the issue of robustness and adaptability in non-equilibrium environments.     

Adaptive management as a tool to improve the conservation of endemic floras: the case of Sicily, Malta and their satellite islands

The presence of endemic species is among the fundamental criteria for characterizing the biodiversity of a territory. Analyzing species richness, extinction level and distribution drivers is an important preliminary step to set conservation priorities and test environmental policies. This study applied the concept of adaptive management to develop strategies for the conservation of endemic floras by considering, as a case study, Sicily, Malta and their neighboring small islands. Adaptive management can be defined as the systematic acquisition and application of reliable information to improve management over time. The development of adaptive conservation strategies aimed preliminary: (1) to quantify endemic plant diversity; (2) to assess the current IUCN knowledge; (3) to analyze the spatial patterns of species distribution in relation to number of colonized habitats, preferential habitats, altitudinal range, and bedrock; (4) to assess whether Natura 2000 network contributed significantly to increase the overlap between endemic distributional areas and protected surface. Strictly Sicilian endemics were 202 taxa amounting to 7.0 % of the whole native flora (c. 2900 taxa). The current picture of extinction risk is still incomplete because over 50 % of endemics were never assessed or assessed with old IUCN criteria. The spatial range size of endemics depended by 40 % on bedrock, and altitudinal and niche breadth. Habitat type did not influence the range size of endemics. The overlap between endemic distributional areas and protected surface increased from 41.3 to 63.3 % with Natura 2000. Adaptive management needs measurable goals to test the progressive improvement of conservation strategies over time, and the reduction in threatened species may be considered as an indicator of successful conservation outcomes. Feedback plays an important role in the periodic revision of biodiversity assessment, distribution modeling, and environmental management, which are fundamental to predict conservation outcomes in the face of extreme uncertainty. In particular, the exhaustive knowledge of the IUCN status is a primary step to implement adaptive measures of conservation, especially as regards endemic floras that are potentially more vulnerable to large-scale or unpredictable and stochastic threats.     

Community‐based wildlife management area supports similar mammal species richness and densities compared to a national park

Community‐based conservation models have been widely implemented across Africa to improve wildlife conservation and livelihoods of rural communities. In Tanzania, communities can set aside land and formally register it as Wildlife Management Area (WMA), which allows them to generate revenue via consumptive or nonconsumptive utilization of wildlife. The key, yet often untested, assumption of this model is that economic benefits accrued from wildlife motivate sustainable management of wildlife. To test the ecological effectiveness (here defined as persistence of wildlife populations) of Burunge Wildlife Management Area (BWMA), we employed a participatory monitoring approach involving WMA personnel. At intermittent intervals between 2011 and 2018, we estimated mammal species richness and population densities of ten mammal species (African elephant, giraffe, buffalo, zebra, wildebeest, waterbuck, warthog, impala, Kirk's dik‐dik, and vervet monkey) along line transects. We compared mammal species accumulation curves and density estimates with those of time‐matched road transect surveys conducted in adjacent Tarangire National Park (TNP). Mammal species richness estimates were similar in both areas, yet observed species richness per transect was greater in TNP compared to BWMA. Species‐specific density estimates of time‐matched surveys were mostly not significantly different between BWMA and TNP, but elephants occasionally reached greater densities in TNP compared to BWMA. In BWMA, elephant, wildebeest, and impala populations showed significant increases from 2011 to 2018. These results suggest that community‐based conservation models can support mammal communities and densities that are similar to national park baselines. In light of the ecological success of this case study, we emphasize the need for continued efforts to ensure that the BWMA is effective. This will require adaptive management to counteract potential negative repercussions of wildlife populations on peoples' livelihoods. This study can be used as a model to evaluate the effectiveness of wildlife management areas across Tanzania.     

Addressing management questions for Ngorongoro Conservation Area, Tanzania, using the Savanna modelling system

Ngorongoro Conservation Area (NCA), in northern Tanzania, is a multiple-use area of importance to Maasai pastoralists and wildlife conservation. We adapted the Savanna modelling system to the NCA, creating an Integrated Management and Assessment System that allows users to assess responses to alternative management actions. We used the system to conduct fifteen experiments reflecting potential management questions. Results suggest that: the distribution of rainfall throughout the year may have a greater impact on the ecosystem than its quantity; cattle may be near a carrying capacity determined not by forage limitations but because of disease risks; increasing survival and reducing disease in livestock yields greater returns than increasing birth rates; allowing livestock to graze in areas where they are currently excluded may lead to a slight increase in livestock populations, but sometimes leads to large declines in wildlife populations; few ecosystem effects were noted when households and cultivation were allowed to grow at 3% per year for 15 years; and when up to 5% of the study area was in cultivation, there were declines ≤16% in livestock and wildlife populations, except for elephants, which declined by 48%. Users may modify our experiments using tools we have developed, or address other NCA management questions.     

Adaptive Co-Management and Grizzly Bear-Human Conflicts in Two Northern Canadian Aboriginal Communities

It has been postulated that the emergence of adaptive co-management can be driven by crises that transform social-ecological systems with low resilience. We compared two concurrent case studies of grizzly bear-human conflicts in northern Canada to assess whether such crises could effect such transformations in bear-human systems. We conclude that they can, evaluate the outcomes, and identify conditions that may explain these observations. For remote communities, horizontal and vertical institutional connections are important for facilitating learning and the integration of information in wildlife management, yet they can be difficult to establish. Events in Baker Lake, Nunavut, showed that without such connections local peoples’ substantial ecological knowledge may not be integrated effectively into decision processes. In the Inuvialuit Settlement Region the quota system for grizzly bear harvests has been able to successfully incorporate both scientific and traditional ecological knowledge, largely because of its cross-scale institutional network. The leadership provided by individual champions was also an important determinant of both case studies’ outcomes.     

Macroinvertebrate conservation in river ecosystems: Challenges,restoration strategies,and integrated management approaches

River ecosystems face growing threats from human-induced stressors, resulting in habitat degradation and biodiversity loss. Crucial to these ecosystems, macroinvertebrates maintain river health and functioning. In this review, we examine the challenges confronting macroinvertebrates, explore restoration strategies and management approaches, and shed light on knowledge gaps and future research directions. Habitat degradation, water pollution, climate change, and invasive species are discussed as key challenges. Various restoration strategies, such as in-stream habitat restoration, flow regime restoration, riparian zone restoration, and connectivity restoration, are evaluated for macroinvertebrate conservation. Integrated catchment management, adaptive management, community-based management, monitoring, and policy integration are highlighted as essential management approaches, and knowledge gaps in long-term monitoring, innovative restoration techniques, climate change resilience, and policy incorporation are identified as areas calling for further research. Ultimately, a proactive, adaptable, and cooperative approach to river management will ensure macroinvertebrate conservation and sustainable river ecosystems.     

Predictive modeling of microhabitats for endemic birds in South Chilean temperate forests using Maximum entropy (Maxent)

Temperate forests of Chile exhibit high biodiversity, which generates a wide range of habitats for wildlife. These valuable natural ecosystems have been affected by major natural and anthropogenic processes that have reduced habitats, resulting in serious ecological problems, given both the high endemism of certain avian groups in these forests and the complexity of their habitat selection. Continued degradation and ecosystem problems could lead to the extinction of such groups. In spite of this possibility, ecologically valuable wildlife conservation is seldom integrated into forest management decision-making processes. This study aims to integrate wildlife into forest management, identifying potential habitats for two endemic birds of high ecological value, the Black throated Huet-Huet (Pteroptochos tarnii), and the Ochre-flanked Tapaculo (Eugralla paradoxa). Both species inhabit an ecotonal area between evergreen and sclerophyllous forests, making them high-quality bio-indicator species for the degree of conservation of temperate forest. The integration of environmental information and a geostatistical model based on the criterion of maximum entropy (Maxent model) identifies the most important variables that explain the presence of each species. Pteroptochos tarnii is less restrictive in its choice of habitat than Eugralla paradoxa, requiring merely certain topographical condition (elevation, ground slope and aspect). However Eugralla paradoxa requires not only the same topographical features, but also eco-geographical characteristics such as distance to trails, waterways and ecotones. Maxent analysis showed that for both species, the model most capable of predicting their choice of microhabitat was not random based, but rather one based on topographical and environmental variables. The integration of Maxent and Geographic Information Systems (GIS) tools could help to solve problems of wildlife habitat conservation and forest planning.
