Identification of critical life-stage habitats is key to successful conservation efforts. Juveniles of some species show great flexibility in habitat use while other species rely heavily on a restricted number of juvenile habitats for protection and food. Considering the rapid degradation of coastal marine habitats worldwide, it is important to evaluate which species are more susceptible to loss of juvenile nursery habitats and how this differs across large biogeographic regions. Here we used a meta-analysis approach to investigate habitat use by juvenile reef fish species in tropical coastal ecosystems across the globe. Densities of juvenile fish species were compared among mangrove, seagrass and coral reef habitats. In the Caribbean, the majority of species showed significantly higher juvenile densities in mangroves as compared to seagrass beds and coral reefs, while for the Indo-Pacific region seagrass beds harbored the highest overall densities. Further analysis indicated that differences in tidal amplitude, irrespective of biogeographic region, appeared to be the major driver for this phenomenon. In addition, juvenile reef fish use of mangroves increased with increasing water salinity. In the Caribbean, species of specific families (e.g. Lutjanidae, Haemulidae) showed a higher reliance on mangroves or seagrass beds as juvenile habitats than other species, whereas in the Indo-Pacific family-specific trends of juvenile habitat utilization were less apparent. The findings of this study highlight the importance of incorporating region-specific tidal inundation regimes into marine spatial conservation planning and ecosystem based management. Furthermore, the significant role of water salinity and tidal access as drivers of mangrove fish habitat use implies that changes in seawater level and rainfall due to climate change may have important effects on how juvenile reef fish use nearshore seascapes in the future. 相似文献

Biogenic volatile organic compounds (BVOCs), in particular dimethyl sulphide (DMS) and isoprene, have fundamental ecological, physiological and climatic roles. Our current understanding of these roles is almost exclusively established from terrestrial or oceanic environments but signifies a potentially major, but largely unknown, role for BVOCs in tropical coastal marine ecosystems. The tropical coast is a transition zone between the land and ocean, characterized by highly productive and biodiverse coral reefs, seagrass beds and mangroves, which house primary producers that are amongst the greatest emitters of BVOCs on the planet. Here, we synthesize our existing understanding of BVOC emissions to produce a novel conceptual framework of the tropical marine coast as a continuum from DMS‐dominated reef producers to isoprene‐dominated mangroves. We use existing and previously unpublished data to consider how current environmental conditions shape BVOC production across the tropical coastal continuum, and in turn how BVOCs can regulate environmental stress tolerance or species interactions via infochemical networks. We use this as a framework to discuss how existing predictions of future tropical coastal BVOC emissions, and the roles they play, are effectively restricted to present day ‘baseline’ trends of BVOC production across species and environmental conditions; as such, there remains a critical need to focus research efforts on BVOC responses to rapidly accelerating anthropogenic impacts at local and regional scales. We highlight the complete lack of current knowledge required to understand the future ecological functioning of these important systems, and to predict whether feedback mechanisms are likely to regulate or exacerbate current climate change scenarios through environmentally and ecologically mediated changes to BVOC budgets at the ecosystem level. 相似文献

Coastal armouring and the reclamation of intertidal areas through the use of seawalls and other artificial structures has been practiced for thousands of years, but its recent expansion in China and elsewhere in Asia has been unprecedented in its rate and intensity. One result has been the recent loss of nearly two‐thirds of tidal flats in the Yellow Sea, a globally unique ecosystem of high ecological value. The severe effects on biodiversity of the recent large‐scale coastal land claim activities in China are well documented, yet some recent studies have emphasized the ecological opportunities provided by such artificial coastal infrastructure in China, in some cases suggesting that the ecological impacts of coastal infrastructure should be reconsidered due to benefits to some rocky shore species in a changing climate. This is cause for concern because, while studying the “new ecology” arising from coastal modification is useful, broad conclusions around the ecological role or conservation gains from seawall construction without adequate contextualization underplays the ecological consequences of large‐scale coastal land claim, and could potentially undermine efforts to achieve biodiversity conservation. Here, we clarify the characteristics of seawall construction in China and summarize the environmental damage and some broadscale impacts caused by this type of infrastructure expansion on the endangered Yellow Sea tidal flats ecosystem. We also highlight the urgent need for all coastal development plans to consider how coastal wetlands and ecosystem functionality can be maximally retained within the development precinct. 相似文献

Shallow soft-sediment systems are mostly dominated by species that, by strongly affecting sediment dynamics, modify their
local environment. Such ecosystem engineering species can have either sediment-stabilizing or sediment-destabilizing effects
on tidal flats. They interplay with abiotic forcing conditions (wind, tide, nutrient inputs) in driving the community structure
and generating spatial heterogeneity, determining the composition of different communities of associated species, and thereby
affecting the channelling of energy through different compartments in the food web. This suggests that, depending on local
species composition, tidal flats may have conspicuously different geomorphology and biological functions under similar external
conditions. Here we use a historical reconstruction of benthic production in the Wadden Sea to construct a framework for the
relationships between human impacts, ecosystem engineering and sediment dynamics. We propose that increased sediment disturbances
by human exploitation interfere with biological controls of sediment dynamics, and thereby have shifted the dominant compartments
of both primary and secondary production in the Wadden Sea, transforming the intertidal from an internally regulated and spatially
heterogeneous, to an externally regulated and spatially homogenous system. This framework contributes to the general understanding
of the interaction between biological and environmental control of ecosystem functioning, and suggests a general framework
for predicting effects of human impacts on soft-bottom ecosystems. 相似文献

From grey to green: Efficacy of eco‐engineering solutions for nature‐based coastal defence 下载免费PDF全文

Climate change is increasing the threat of erosion and flooding along coastlines globally. Engineering solutions (e.g. seawalls and breakwaters) in response to protecting coastal communities and associated infrastructure are increasingly becoming economically and ecologically unsustainable. This has led to recommendations to create or restore natural habitats, such as sand dunes, saltmarsh, mangroves, seagrass and kelp beds, and coral and shellfish reefs, to provide coastal protection in place of (or to complement) artificial structures. Coastal managers are frequently faced with the problem of an eroding coastline, which requires a decision on what mitigation options are most appropriate to implement. A barrier to uptake of nature‐based coastal defence is stringent evaluation of the effectiveness in comparison to artificial protection structures. Here, we assess the current evidence for the efficacy of nature‐based vs. artificial coastal protection and discuss future research needs. Future projects should evaluate habitats created or restored for coastal defence for cost‐effectiveness in comparison to an artificial structure under the same environmental conditions. Cost‐benefit analyses should take into consideration all ecosystem services provided by nature‐based or artificial structures in addition to coastal protection. Interdisciplinary research among scientists, coastal managers and engineers is required to facilitate the experimental trials needed to test the value of these shoreline protection schemes, in order to support their use as alternatives to artificial structures. This research needs to happen now as our rapidly changing climate requires new and innovative solutions to reduce the vulnerability of coastal communities to an increasingly uncertain future. 相似文献

Ecosystem engineering is increasingly recognized as a relevant ecological driver of diversity and community composition. Although engineering impacts on the biota can vary from negative to positive, and from trivial to enormous, patterns and causes of variation in the magnitude of engineering effects across ecosystems and engineer types remain largely unknown. To elucidate the above patterns, we conducted a meta‐analysis of 122 studies which explored effects of animal ecosystem engineers on species richness of other organisms in the community. The analysis revealed that the overall effect of ecosystem engineers on diversity is positive and corresponds to a 25% increase in species richness, indicating that ecosystem engineering is a facilitative process globally. Engineering effects were stronger in the tropics than at higher latitudes, likely because new or modified habitats provided by engineers in the tropics may help minimize competition and predation pressures on resident species. Within aquatic environments, engineering impacts were stronger in marine ecosystems (rocky shores) than in streams. In terrestrial ecosystems, engineers displayed stronger positive effects in arid environments (e.g. deserts). Ecosystem engineers that create new habitats or microhabitats had stronger effects than those that modify habitats or cause bioturbation. Invertebrate engineers and those with lower engineering persistence (<1 year) affected species richness more than vertebrate engineers which persisted for >1 year. Invertebrate species richness was particularly responsive to engineering impacts. This study is the first attempt to build an integrative framework of engineering effects on species diversity; it highlights the importance of considering latitude, habitat, engineering functional group, taxon and persistence of their effects in future theoretical and empirical studies. 相似文献

Introduced ecosystem engineers can severely modify the functioning on invaded systems. Species-level effects on ecosystem
functioning (EF) are context dependent, but the effects of introduced ecosystem engineers are frequently assessed through
single-location studies. The present work aimed to identify sources of context-dependence that can regulate the impacts of
invasive ecosystem engineers on ecosystem functioning. As model systems, four locations where the bivalve Ruditapes philippinarum (Adams and Reeve) has been introduced were investigated, providing variability in habitat characteristics and community composition.
As a measure of ecosystem engineering, the relative contribution of this species to community bioturbation potential was quantified
at each site. The relevance of bioturbation to the local establishment of the mixing depth of marine sediments (used as a
proxy for EF) was quantified in order to determine the potential for impact of the introduced species at each site. We found
that R. philippinarum is one of the most important bioturbators within analysed communities, but the relative importance of this contribution at
the community level depended on local species composition. The net contribution of bioturbation to the establishment of sediment
mixing depths varied across sites depending on the presence of structuring vegetation, sediment granulometry and compaction.
The effects of vegetation on sediment mixing were previously unreported. These findings indicate that the species composition
of invaded communities, and the habitat characteristics of invaded systems, are important modulators of the impacts of introduced
species on ecosystem functioning. A framework that encompasses these aspects for the prediction of the functional impacts
of invasive ecosystem engineers is suggested, supporting a multi-site approach to invasive ecology studies concerned with
ecosystem functioning. 相似文献

After biocontrol: Assessing indirect effects of insect releases 总被引:7,自引:2,他引:5
Development of biological control agents for weeds has been motivated by the need to reduce the abundance and distribution of a pest plant where chemical and mechanical control were not cost effective. Primary objectives have been direct reduction in abundance of the target and, secondarily, the increase of desirable species. Recently, wildland weeds have become a focus of biological control projects. Here, desired outcomes include both reduction of the target and indirect effects of increased diversity and abundance of native species and restoration of ecosystem services. However, goals and benefits of biocontrol programs are not always well-articulated and direct and indirect impacts are not easily predicted. We evaluated the extent to which several successful biological control projects for weeds of rangelands and waterways measured indirect impacts on invaded ecosystems. We also examined biocontrol of a wildland pest tree for which the principal objective is restoration of ecosystem services. We found few quantitative assessments of the impacts of pest plant reduction on community composition or ecosystem processes. All examples documented variation in the impacts of agent(s) across the invasive range of the target plant as well as variation in impacts on the invaded ecosystem. However, without appropriate quantitative information, we cannot evaluate site characteristics that may influence vegetation responses. Most successful weed management programs integrated the use of biocontrol agents with other weed management strategies, especially modifications of disturbance and competing vegetation. Discussion and evaluation of responses of nontarget species would improve our understanding of the context-specificity of outcomes. 相似文献

Several non-indigenous bivalve species have been colonising aquatic ecosystems worldwide, in some cases with great ecological
and economic impacts. In this paper, we focus on the ecosystem engineering attributes of non-indigenous invasive bivalves
(i.e., the capacities of these organisms to directly or indirectly affect the availability of resources to other species by
physically modifying the environment). By reviewing the ecology of several invasive bivalves we identify a variety of mechanisms
via which they modify, maintain and/or create habitats. Given the usually high densities and broad spatial distributions of
such bivalves, their engineering activities can significantly alter ecosystem structure and functioning (e.g., changes in
sediment chemistry, grain size, and organic matter content via bioturbation, increased light penetration into the water column
due to filter feeding, changes in near bed flows and shear stress due to the presence of shells, provision of colonisable
substrate and refuges by shells). In addition, changes in ecosystem structure and functioning due to engineering by invasive
bivalves often have very large economic impacts. Given the worldwide spread of non-indigenous bivalves and the varied ways
in which they physically modify habitats, their engineering effects should receive more serious consideration in restoration
and management initiatives. 相似文献

The Great Lakes ecosystem is home to at least 139 non-indigenous species of fauna and flora which have become established following invasions or intentional introductions. About ten percent of the exotic species have caused economic or ecological damage to the system. A sample of this group is reviewed to determine if ecological concepts are useful in helping to predict colonization and impacts to ecosystem health. Successful colonization by most of the species reviewed was predictable from habitat requirements and behaviour. Ecosystem disturbance was a factor in the success of some of the colonists but was not an overriding ecological requirement. Perturbations to ecosystem health are more difficult to predict and in most cases were not readily apparent from knowledge about the ecology of invaders or native communities. The main damage to ecosystem health by the species reviewed resulted from competition, predation and habitat modification. Difficulties in predicting both invasions and damage from successful colonists point to the need to prevent non-indigenous species from reaching the Great Lakes basin. 相似文献

Coastal sediments in sheltered temperate locations are strongly modified by ecosystem engineering species such as marsh plants,
seagrass, and algae as well as by epibenthic and endobenthic invertebrates. These ecosystem engineers are shaping the coastal
sea and landscape, control particulate and dissolved material fluxes between the land and sea, and between the benthos and
the passing water or air. Above all, habitat engineering exerts facilitating and inhibiting effects on biodiversity. Despite
a strongly growing interest in the functional role of ecosystem engineering over the recent years, compared to food web analyses,
the conceptual understanding of engineering-mediated species interactions is still in its infancy. In the present paper, we
provide a concise overview on current insights and propose two hypotheses on the general mechanisms by which ecosystem engineering
may affect biodiversity in coastal sediments. We hypothesise that autogenic and allogenic ecosystem engineers have inverse
effects on epibenthic and endobenthic biodiversity in coastal sediments. The primarily autogenic structures of the epibenthos
achieve high diversity at the expense of endobenthos, whilst allogenic sediment reworking by infauna may facilitate other
infauna and inhibits epibenthos. On a larger scale, these antagonistic processes generate patchiness and habitat diversity.
Due to such interaction, anthropogenic influences can strongly modify the engineering community by removing autogenic ecosystem
engineers through coastal engineering or bottom trawling. Another source of anthropogenic influences comes from introducing
invasive engineers, from which the impact is often hard to predict. We hypothesise that the local biodiversity effects of
invasive ecosystem engineers will depend on the engineering strength of the invasive species, with engineering strength defined
as the number of habitats it can invade and the extent of modification. At a larger scale of an entire shore, biodiversity
need not be decreased by invasive engineers and may even increase. On a global scale, invasive engineers may cause shore biota
to converge, especially visually due to the presence of epibenthic structures. 相似文献

Distributional shifts in species ranges provide critical evidence of ecological responses to climate change. Assessments of climate-driven changes typically focus on broad-scale range shifts (e.g. poleward or upward), with ecological consequences at regional and local scales commonly overlooked. While these changes are informative for species presenting continuous geographic ranges, many species have discontinuous distributions—both natural (e.g. mountain or coastal species) or human-induced (e.g. species inhabiting fragmented landscapes)—where within-range changes can be significant. Here, we use an ecosystem engineer species (Sabellaria alveolata) with a naturally fragmented distribution as a case study to assess climate-driven changes in within-range occupancy across its entire global distribution. To this end, we applied landscape ecology metrics to outputs from species distribution modelling (SDM) in a novel unified framework. SDM predicted a 27.5% overall increase in the area of potentially suitable habitat under RCP 4.5 by 2050, which taken in isolation would have led to the classification of the species as a climate change winner. SDM further revealed that the latitudinal range is predicted to shrink because of decreased habitat suitability in the equatorward part of the range, not compensated by a poleward expansion. The use of landscape ecology metrics provided additional insights by identifying regions that are predicted to become increasingly fragmented in the future, potentially increasing extirpation risk by jeopardising metapopulation dynamics. This increased range fragmentation could have dramatic consequences for ecosystem structure and functioning. Importantly, the proposed framework—which brings together SDM and landscape metrics—can be widely used to study currently overlooked climate-driven changes in species internal range structure, without requiring detailed empirical knowledge of the modelled species. This approach represents an important advancement beyond predictive envelope approaches and could reveal itself as paramount for managers whose spatial scale of action usually ranges from local to regional. 相似文献

A shift from traditional engineering approaches to ecologically-based techniques will require changing societal values regarding ‘how and what’ is defined as engineering and design. Non-human species offer many ecological engineering examples that are often beneficial to ecosystem function and other biota. For example, organisms known as ‘ecosystem engineers’ build, modify, and destroy habitat in their quest for food and survival. Similarly, ‘keystone species’ have greater impacts on community or ecosystem function than would be predicted from their abundance. The capacity of these types of organisms to affect ecosystems is great. They exert controlling influences over ecosystems and communities by altering resource allocation, creating habitats and modifying relative competitive advantages.Species’ effects in ecosystems, although context-dependent, can be evaluated as ‘beneficial’ or ‘detrimental’. The evaluation depends on whether effects on other species or ecosystem function are more or less desirable from a given perspective. Organisms with beneficial impacts facilitate the presence of other species, employ efficient nutrient cycling, and are sometimes characterized by specific mutualisms. In contrast, many cases of detrimental engineering are found from introduced (i.e., exotic) species and are characterized by a loss of species richness, a lack of nutrient retention and the degradation of ecosystem integrity. Species’ impacts on ecosystems and community traits have been quantified in ecological studies and can be used similarly to understand, design and model human engineering structures and impacts on the landscape. Emulation of species with beneficial impacts on ecosystems can provide powerful guidance to the goals of ecological engineering. Using role model organisms that have desirable effects on species diversity and ecosystem function will be important in developing alternatives to traditional engineering practices. 相似文献

As expressed in the Ramsar Convention, the wise use of wetlands, including coastal lagoons, is one of the greatest environmental concerns across the globe. Seagrass beds are the key element for sustaining coastal lagoon ecosystems. Eutrophication, especially by nitrogen and phosphorus, has degraded many coastal waters and has been invoked as a major cause of seagrass disappearance worldwide. Seagrass had been used as fertilizer in Japan, and the removal of seagrass contributed to the decline of nutrients in the water. The shifts of primary producers from rooted macrophytes to phytoplankton occurred simultaneously between the mid-1950s and 1965 in Japan??presumably because of the wide use of herbicides for rice paddies. Increased phytoplankton induced the increase of fishery yield of clam on one hand and non-edible biofouling species on the other. Because a phytoplankton-dominated ecosystem is easily oxygen depleted at the bottom with the accumulation of organic matter of phytoplankton origin, preventing hypoxia is the key factor to maintain high secondary production for bivalve fisheries and sustainable use of the ecosystem of coastal lagoons. 相似文献

Ecosystem engineering, the physical modification of the environment by organisms, is a common and often influential process whose significance to food web structure and dynamics is largely unknown. In the light of recent calls to expand food web studies to include non‐trophic interactions, we explore how we might best integrate ecosystem engineering and food webs. We provide rationales justifying their integration and present a provisional framework identifying how ecosystem engineering can affect the nodes and links of food webs and overall organization; how trophic interactions with the engineer can affect the engineering; and how feedbacks between engineering and trophic interactions can affect food web structure and dynamics. We use a simple integrative food chain model to illustrate how feedbacks between the engineer and the food web can alter 1) engineering effects on food web dynamics, and 2) food web responses to extrinsic environmental perturbations. We identify four general challenges to integration that we argue can readily be met, and call for studies that can achieve this integration and help pave the way to a more general understanding of interaction webs in nature. Synthesis All species are affected by their physical environment. Because ecosystem engineering species modify the physical environment and belong to food webs, such species are potentially one of the most important bridges between the trophic and non‐trophic. We examine how to integrate the so far, largely independent research areas of ecosystem engineering and food webs. We present a conceptual framework for understanding how engineering can affect food webs and vice versa, and how feedbacks between the two alter ecosystem dynamics. With appropriate empirical studies and models, integration is achievable, paving the way to a more general understanding of interaction webs in nature. 相似文献
