Nova Baden State Park (NBSP) is located in the Brazilian Atlantic Forest which is a biodiversity hotspot and priority for conservation. Our aim is to provide a list of large and medium-sized mammal species recorded in NBSP. We made a camera trap survey and opportunistic observations from December 2014 to September 2015, and searched the grey literature. We recorded 12 large and medium-sized mammals in our survey and 11 more species listed in grey literature. The 23 species registered for NBSP belong to eight orders (Carnivora, Primates, Rodents, Cingulata, Pilosa, Didephimorphia, Lagomorpha and Artiodactyla), including threatened species at local, national and global levels. With an important mammal biodiversity, we concluded that avoidance of poaching and the control of domestic dogs need to be priorities for biodiversity conservation of NBSP, with a political management that includes the local community in Park activities.

Illegal wildlife trafficking has negative effects on biodiversity conservation at both global and local scale. Therefore, the establishment of appropriate conservation measures requires local studies that quantify this problem. The objective of this work was to quantify and characterize the species of birds and mammals seized in the period 2016-2017, at the Valle Alto Wildlife Rescue Centre and Wildlife Refuge. The study showed that 212 specimens belonging to 41 different species were confiscated. More birds than mammals were confiscated, and a greater proportion of birds were included in a national and international threat category. A clear preference for primates, parrots and squirrels was found. Furthermore, the presence of species with a distribution range outside the study area revealed the existence of the transportation of species from other parts of the country. Although these data are only a sample of what is actually trafficked in the country, they provide an approach of the type of species that are illegally trafficked in this biodiversity hotspot.

AbstractThe Upper Guinea rainforest zone in West Africa is considered a biodiversity hotspot and contains important habitats for threatened and endemic mammals, yet this region remains poorly known particularly for small mammals. The aim of this study was to survey small mammals in a Liberian and Guinean cross-border conservation area, the Ziama-Wonegizi-Wologizi landscape. We recorded a total of 52 small mammal species, including 26 bats, 15 rodents, 10 shrews, one otter-shrew, of which one rodent species was new to science (Colomys sp. nov.). We also documented the first country records of the bats Chaerephon aloysiisabaudiae, Pseudoromicia brunnea and Pipistrellus inexspectatus from Guinea, and the shrews Crocidura douceti and Crocidura grandiceps from Liberia. Furthermore, we recorded the recently described bat Nycticeinops happoldorum from Wologizi and Ziama, and we documented the presence of Micropotamogale lamottei at Wologizi, which represents the fourth known locality for this globally threatened species. Finally, the forests of Wologizi and Ziama support numerous threatened species. The results of our survey demonstrate the importance of this region for small mammals and support the creation of a transboundary protected area that will encompass the entire forest landscape.

Jurasaidae are a family of neotenic elateroid beetles which was described recently from the Brazilian Atlantic Forest biodiversity hotspot based on three species in two genera. All life stages live in the soil, including the larviform females, and only adult males are able to fly. Here, we report the discovery of two new species, Jurasai miraculum sp. nov. and J. vanini sp. nov., and a new, morphologically remarkable population of J. digitusdei Rosa et al., 2020. Our discovery sheds further light on the diversity and biogeography of the group. Most species of Jurasaidae are known from the rainforest remnants of the Atlantic Forest, but here for the first time we report a jurasaid species from the relatively drier Atlantic Forest/Caatinga transitional zone. Considering our recent findings, minute body size and cryptic lifestyle of all jurasaids, together with potentially high numbers of yet undescribed species of this family from the Atlantic Forest and possibly also other surrounding ecoregions, we call for both field research in potentially suitable localities as well as for a detailed investigation of a massive amount of already collected but still unprocessed materials deposited in a number of Brazilian institutes, laboratories and collections.

The resource extraction that powers global economies is often manifested in Indigenous Peoples’ territories. Indigenous Peoples living on the land are careful observers of resulting biodiversity changes, and Indigenous-led research can provide evidence to inform conservation decisions. In the Nearctic western boreal forest, landscape change from forest harvesting and petroleum extraction is intensive and extensive. A First Nations community in the Canadian oil sands co-created camera-trap research to explore observations of presumptive species declines, seeking to identify the relative contributions of different industrial sectors to changes in mammal distributions. Camera data were analyzed via generalized linear models in a model-selection approach. Multiple forestry and petroleum extraction features positively and negatively affected boreal mammal species. Pipelines had the greatest negative effect size (for wolves), whereas well sites had a large positive effect size for multiple species, suggesting the energy sector as a target for co-management. Co-created research reveals spatial relationships of disturbance, prey, and predators on Indigenous traditional territories. It provides hypotheses, tests, and interpretations unique to outside perspectives; Indigenous participation in conservation management of their territories scales up to benefit global biodiversity conservation.

The flora of Laos remains one of the least known within the Indo-Burma biodiversity hotspot. A floristic inventory was carried out in Phou Hin Poun National Biodiversity Conservation Area, an under-explored area of the Khammouane Limestone. This study provides a list of 27 taxa that are additions to the most recent country checklists. The Ebenaceae, Euphorbiaceae and Myrtaceae are the families with the highest species number. In this list, four species are endemic to Indochina (Cambodia, Laos and Vietnam): Cynometra dongnaiensis Pierre, Jasminum vidalii P.S.Green, Memecylon chevalieri Guillaumin and Pothos gigantipes Buchet ex P.C.Boyce. These results illustrate the paucity of our knowledge of the region surveyed and of the flora of Laos in general.

Trophic rewilding is a restoration strategy focusing on the restoration of trophic interactions to promote self-regulating, biodiverse ecosystems. It has been proposed as an alternative to traditional conservation management in abandoned or defaunated areas. Arthropods constitute the most species-rich group of eukaryotic organisms, but are rarely considered in rewilding. Here, we first present an overview of direct and indirect pathways by which large herbivores and predators affect arthropod communities. We then review the published evidence of the impacts of rewilding with large herbivores on arthropods, including grey literature. We find that systematic monitoring is rare and that a comparison with a relevant control treatment is usually lacking. Nevertheless, the available data suggest that when the important process of top-down control of large-herbivore populations is missing, arthropod diversity tends to decrease. To ensure that rewilding is supportive of biodiversity conservation, we propose that if natural processes can only partially be restored, substitutes for missing processes are applied. We also propose that boundaries of acceptable outcomes of rewilding actions should be defined a priori , particularly concerning biodiversity conservation, and that action is taken when these boundaries are transgressed. To evaluate the success of rewilding for biodiversity, monitoring of arthropod communities should be a key instrument. This article is part of the theme issue ‘Trophic rewilding: consequences for ecosystems under global change’.

Community forests have been established worldwide to sustainably manage forest ecosystem services while maintaining the livelihoods of local residents. The Chitwan National Park in Nepal is a world-renowned biodiversity hotspot, where community forests were consolidated in the park’s buffer zone after 1993. These western Chitwan community forests stand as the frontiers of human–environment interactions, nurturing endangered large mammal species while providing significant natural resources for local residents. Nevertheless, no systematic forest cover assessment has been conducted for these forests since their establishment. In this study, we examined the green vegetation dynamics of these community forests for the years 1988–2018 using Landsat surface reflectance products. Combining an automatic water extraction index, spectral mixture analysis and the normalized difference fraction index (NDFI), we developed water masks and quantified the water-adjusted green vegetation fractions and NDFI values in the forests. Results showed that all forests have been continuously greening up since their establishment, and the average green vegetation cover of all forests increased from approximately 30% in 1988 to above 70% in 2018. With possible contributions from the invasion of exotic understory plant species, we credit community forestry programs for some of the green-up signals. Monitoring of forest vegetation dynamics is critical for evaluating the effectiveness of community forestry as well as developing sustainable forest management policies. Our research will provide positive feedbacks to local community forest committees and users.

Abstract ContextCamera traps are one of the most popular tools used to study wildlife worldwide. Numerous recent studies have evaluated the efficiency and effectiveness of camera traps as a research tool. Nonetheless, important aspects of camera-trap methodology remain in need of critical investigation. One such issue relates to camera-trap viewshed visibility, which is often compromised in the field by physical obstructions (e.g. trees) or topography (e.g. steep slopes). The loss of visibility due to these obstructions could affect wildlife detection rates, with associated implications for study inference and management application. AimsWe aimed to determine the effect of camera-trap viewshed obstruction on wildlife detection rates for a suite of eight North American species that vary in terms of ecology, commonness and body size. MethodsWe deployed camera traps at 204 sites throughout an extensive semi-urban park system in Cleveland, Ohio, USA, from June to September 2016. At each site, we quantified camera-trap viewshed obstruction by using a cover-board design. We then modelled the effects of obstruction on wildlife detection rates for the eight focal species. Key resultsWe found that detection rates significantly decreased with an increasing viewshed obstruction for five of the eight species, including both larger and smaller mammal species (white-tailed deer, Odocoileus virginianus, and squirrels, Sciurus sp., respectively). The number of detections per week per camera decreased two- to three-fold as visibility at a camera site decreased from completely free of obstruction to mostly obstructed. ConclusionsThese results imply that wildlife detection rates are influenced by site-level viewshed obstruction for a variety of species, and sometimes considerably so. ImplicationsResearchers using camera traps should address the potential for this effect to ensure robust inference from wildlife image data. Accounting for viewshed obstruction is critical when interpreting detection rates as indices of abundance or habitat use because variation in detection rate could be an artefact of site-level viewshed obstruction rather than due to underlying ecological processes.
