Understanding non-compliance: Local people’s perceptions of natural resource exploitation inside two national parks in northeast Brazil

Non-compliance with conservation regulations is a key issue for protected area management effectiveness in most parts of the world. Effectively managing such behaviours requires a clear understanding of who is non-compliant, what is driving their non-compliance, and what the likely conservation consequences of compliant and non-compliant behaviours are. However, such information is notoriously difficult to obtain due to the (understandable) reluctance of transgressors to discuss illegal activities. Here, we adopt the Kiping social survey method to assess the drivers of non-compliance with resource use rules in two national parks (Catimbau and Chapada Diamantina) in Northeast Brazil. The method is therefore used to support the exploration of suitable solutions for coping with non-compliance on the ground. We found high levels of social acceptability for illegal behaviours in both Parks, though hunting and cutting trees inside the park were viewed more negatively by local residents. Respondents from both areas generally supported the collection of plants and firewood, especially by poor people and local residents. Acceptance of illegal activities was statistically correlated with awareness of park regulations in both parks and, in Catimbau NP, it was also prevalent among older, poorer and less educated residents. To deter non-compliance, a mix of interventions from more coercive measures to softer instruments are recommended, especially in Catimbau NP where the area is not patrolled and the close proximity of indigenous lands gives rise to land- and resource-use conflicts.     

The Plymouth Laboratory and the Institutionalization of Experimental Zoology in Britain in the 1920s

The Plymouth Laboratory of the Marine Biological Association of the United Kingdom (1884) was founded in 1888. In addition to conducting morphological and other biological research, the founders of the laboratory aimed at promoting research in experimental zoology which will be used in this paper as a synonym for e.g. experimental embryology, comparative physiology or general physiology. This dream was not fully realized until 1920. The Great War and its immediate aftermath had a positive impact on the development of the Plymouth Laboratory. The war greatly upset the operation of the Zoological Station in Naples and the ensuing crisis in its operations was closely related to the establishment of the physiological department in Plymouth in 1920. Two other key factors in the Plymouth story were the establishment of the Development Fund in 1909, which began contributing funds to the Plymouth Laboratory in 1912, and the patronage of the Cambridge zoologist George P. Bidder (1863–1954). This paper will focus on the combined influence of the Development Fund and Bidder on the development of the Plymouth Laboratory from around 1902 through the early 1920s, and the important role the laboratory played in promoting experimental zoology in Britain in the 1920s.     

When Invasive Species have Benefits as well as Costs: Managing <Emphasis Type="Italic">Carex kobomugi</Emphasis> (Asiatic sand sedge) in New Jersey’s Coastal Dunes

Asiatic sand sedge, Carex kobomugi,was accidentally introduced into North America approximately a century ago and is now widespread along the Northeast coast of the USA. This paper documents the rapid spread rate of this species in two New Jersey coastal parks. Also documented are declines in native plant densities, species richness and diversity in invaded areas. Although C. kobomugi expansion is having negative ecological impacts, the species is a potentially important dune stabilizer, so its control or removal demands special care. A removal program was initiated in 1999, using carefully directed applications of Roundup^®, which was designed such that it would spare non-target plants, leaving them in place to hold the dunes. We show that this approach reduced, but did not eliminate, C. kobomugi, even after repeated herbicide application. Native plant stem densities, species richness and species diversity in treated and untreated stands were similar, suggesting that this application technique did effectively spare non-target plants. However, effective eradication of C. kobomugi would probably require more frequent and aggressive broadband herbicide application, precluding beneficial effects of localized treatment (both ecological and increased dune stability due to spared plants).     

Short‐term Impacts of Fish Removal from Small Amazonian Forest Streams

Collecting freshwater zoological material for research purposes is common and necessary, but its impact on biological communities is often overlooked. We tested the impacts of a conventional ichthyological collection in small forest streams and showed that fish assemblages recover after a few months. We highlight ecological traits and habitat characteristics that might exacerbate the impacts of repeated removal of fish in long‐term investigations, and advocate for the use of a capture‐release approach whenever possible.     

Distribution and management of invasive alien plant species in protected areas in Central Europe

Protected areas play a key role in biodiversity conservation, yet they face numerous pressures including the spread of invasive alien species (IAS). We designed a structured online survey to investigate the distribution and management of 53 invasive alien plant species in large protected areas, i.e. national parks and biosphere reserves, in eight Central European countries. We contacted 93 protected areas management authorities, of which 46 replied. In 44 protected areas (96% of those responding), at least one IAS was present, and in 37 protected areas (80%) IAS were managed. On average, 11.2 ± 6.9 IAS were present per protected area and 4.3 ± 3.4 (41%) of these were managed. A one-way ANOVA showed no significant difference in the number of IAS present or managed between the different protected area designations (national parks, biosphere reserves). Similarly, neither the size nor the founding year of the protected area influenced the number of IAS present or managed. Thirty-one species (58%) were managed in at least one protected area. The most widely managed species were Fallopia japonica (23 protected areas), Heracleum mantegazzianum (20), and Impatiens glandulifera (16). The amount of financial resources devoted to IAS management was rather low, corresponding to 3.1 ± 4.4% of the total budget for natural resources management of the protected areas. We conclude that a lack of dedicated funding for IAS management in most protected areas and a lack of coordinated response between protected areas currently limit the effectiveness of the IAS management. In particular, an increased exchange of expertise between protected areas, and the development of minimum standards for IAS surveillance and management are pivotal. In addition, documenting best practice examples and synthesizing lessons learned in IAS management are urgently needed.     

Seasonal patterns of habitat selection of the House Sparrow Passer domesticus in the urban landscape of Valencia (Spain)

The habitat selection and the factors influencing the distribution of the House Sparrow Passer domesticus in the municipality of Valencia (76 km²) were studied during the winter and breeding season. House Sparrows positively selected urban parks and gardens, patches of derelict land and horticultural fields; they avoided the built-up habitat and the orange groves. In the urban landscape, the abundance of sparrows peaked in areas providing intermediate cover of the built-up habitat; it was positively driven by the amount of park land per unit area, and negatively by the size of urban parks. Our results suggest that the conservation and habitat enhancement of even the smallest parks and gardens are likely key factors in addressing the decline of the House Sparrow in many cities.     

The phantom chorus: birdsong boosts human well-being in protected areas

Spending time in nature is known to benefit human health and well-being, but evidence is mixed as to whether biodiversity or perceptions of biodiversity contribute to these benefits. Perhaps more importantly, little is known about the sensory modalities by which humans perceive biodiversity and obtain benefits from their interactions with nature. Here, we used a ‘phantom birdsong chorus'' consisting of hidden speakers to experimentally increase audible birdsong biodiversity during ‘on'' and ‘off'' (i.e. ambient conditions) blocks on two trails to study the role of audition in biodiversity perception and self-reported well-being among hikers. Hikers exposed to the phantom chorus reported higher levels of restorative effects compared to those that experienced ambient conditions on both trails; however, increased restorative effects were directly linked to the phantom chorus on one trail and indirectly linked to the phantom chorus on the other trail through perceptions of avian biodiversity. Our findings add to a growing body of evidence linking mental health to nature experiences and suggest that audition is an important modality by which natural environments confer restorative effects. Finally, our results suggest that maintaining or improving natural soundscapes within protected areas may be an important component to maximizing human experiences.     

Effect of rapid urbanization on plant species diversity in municipal parks, in a new Chinese city: Shenzhen

Shenzhen was a famous typical rapid-urbanization city in China, and this study compares plant species diversity in urban parks from the start of urbanization through 2011. Results show that the plant species biodiversity increased rapidly: the rate changed from 140% to 980% and the average increasing rate was 406.90%, but only 12.59% of plants spread into the park naturally. Shrubs had the highest rate; with change increasing from 20.70% to 43.54%, they replaced trees to become the dominant type. The biodiversity of native plants also increased, but their proportion relative to all species had declined. The homogenization of plant species in the parks increased; more than half of the plant species (62.24%) are located in 5–7 parks at once now, compared with 65.52% of species located in only 2–3 parks at the start of the study. The increase of species was faster than the increase of families; many new species planted belong to a few specific families. The ratio of species to families declined from 0.40 to 0.32. Results indicate that the rapid increase of plant species diversity as well as their homogenization happened in the initial stage of urbanization, and so rapid urbanization might be the major factor in the changes in plant species diversity in municipal parks. Rapid urbanization was an important cause of change in plant species diversity.     

A survey of research in North American zoos and aquariums

To assess the current status of research in zoos and aquariums, a 36-item survey, which replicated and expanded upon an earlier survey [Finlay and Maple, 1986], was sent to 173 American Zoo and Aquarium Association (AZA) institutions. A response rate of 71% was achieved after a second mailing. The results show that the role of research in AZA institutions has increased in the last decade. The percentage of zoos and aquariums that report conducting research, that list research as an objective of the institution, and that have a research committee/department have all increased. The number of individuals involved in research per institution has approximately doubled since 1986, and slightly less than half of responding institutions currently have a full-time position dedicated to administering research. Lack of available funds, time, and qualified personnel are the most common reasons reported for not conducting research. Zoo Biol 17:167–180, 1998. © 1998 Wiley-Liss, Inc.
