Two methods frequently used to sample wildlife are based on local ecological knowledge (LEK), which is low cost and draws on substantial human experience, and camera trap sampling (CT), which is widely used due to its spatial replicability and the increasing diversity of analytical frameworks. We compared the effectiveness of both methods in assessing the impact of hunting on wildlife at 70 local community catchments across the Brazilian Amazon. We did this by assessing local occurrences of 17 focal species as recounted by 187 subsistence hunters in interviews and by assessing data from 631 CT deployments. We evaluated correlations among the distances from the nearest community at which species and species groups occurred, derived from either LEK or CT data. We also assessed how species' morphological and socioecological traits influenced estimates derived from LEK and CT. Estimates derived from LEK were more strongly correlated with species abundance than with occupancy estimates. Large-bodied, harvest-sensitive species, such as tapir (<i>Tapirus terrestris</i>), white-lipped peccary (<i>Tayassu pecari</i>), and curassow (<i>Crax</i> or <i>Pauxi</i> spp.), were spatially depleted more than 15 km away from human communities. These species showed particularly strong positive correlations across all estimates. The precision of LEK estimates increased with independent data on local game species abundance. These results underline the utility of data derived from LEK in assessing patterns of local wildlife abundance, especially for large-bodied species sensitive to hunting pressure. Local ecological knowledge-based methods are valuable in their own right, especially in areas where alternative sampling methods are lacking and human impact is not matched by conservation efforts.</p>","PeriodicalId":10689,"journal":{"name":"Conservation Biology","volume":"39 3","pages":""},"PeriodicalIF":5.2,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Morcatty","doi":"10.1111/cobi.70041","DOIUrl":"https://doi.org/10.1111/cobi.70041","url":null,"abstract":"&lt;p&gt;Over the past 50 years, conservation science has shifted from a species-centered to a people and nature-centered field of research and practice (Mace, &lt;span&gt;2014&lt;/span&gt;), and Brazil has played an important role in this transformation. Brazil is a biologically and culturally megadiverse country. It contains 6 of the world's terrestrial biomes and a large coastal area (Scarano et al., &lt;span&gt;2024&lt;/span&gt;), as well as over 300 Indigenous ethic groups that speak 254 different languages and millions of resource-dependent communities (IBGE, &lt;span&gt;2017&lt;/span&gt;). Biomes, such as the Amazon rainforest and the Pantanal wetland, are globally iconic places for biodiversity and host healthy populations of numerous endemic and threatened species, but at the same time, they have a millennial history of human habitation and in some cases were cocreated by nature and people. In the Amazon, pre-Columbian management has significantly shaped forest composition; domesticated tree species dominate vast landscapes and influence local patterns of species richness and abundance (Levis et al., &lt;span&gt;2017&lt;/span&gt;; Maezumi et al. &lt;span&gt;2018&lt;/span&gt;). The distribution of species, such as Brazil nut (&lt;i&gt;Bertholletia excelsa&lt;/i&gt;), is particularly indicative of sustained human cultivation and landscape use (Shepard &amp; Ramirez, &lt;span&gt;2011&lt;/span&gt;). It is estimated that at least 6 million forest-dependent people now live in communities and rural settlements in the Brazilian Amazon (IBGE, &lt;span&gt;2017&lt;/span&gt;) and that 34 million people live in the Amazon region (Charity et al., &lt;span&gt;2016&lt;/span&gt;). In the Pantanal, over 90% of the area is occupied by cattle ranches (Chiaravalloti et al., &lt;span&gt;2023&lt;/span&gt;), and there are signs of human settlements 27,000 years BP on the northern border of the biome (Vialou et al. &lt;span&gt;2017&lt;/span&gt;). The Caatinga, an exclusively Brazilian biome, is the most densely inhabited semiarid land in the world (Tabarelli et al., &lt;span&gt;2017&lt;/span&gt;). Atlantic Forest and Cerrado are among the 10 original biodiversity hotspots due to their high levels of endemic species and deforestation rates (Myers et al., &lt;span&gt;2000&lt;/span&gt;). The Pampas, an extensive grassland biome, has over 10 million people living in its expansive plains, agricultural lands, and urban centers (Overbeck et al., &lt;span&gt;2007&lt;/span&gt;). Therefore, the implementation of conservation approaches strictly based on species protection has always faced challenges in Brazil (Silva, &lt;span&gt;2005&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;People-centered conservation programs emerged in different forms and in different regions of Brazil. They started to appear between the 1980s and 1990s, when the international conservation science and practice agenda was mostly still part of the “nature despite people” approach (Mace, &lt;span&gt;2014&lt;/span&gt;). Among the earliest and most influential examples was the Amazon's Rubber Tapper Movement, which laid the foundation to the creation of sustainable use protected areas.

Now, conservationists are beginning to harness the power of telling stories to achieve conservation goals. We introduce the past stories hypothesis, in which we argue that existing conservation storytelling practices can be improved by incorporating the longer term perspectives available from geohistorical records, such as sediment cores, fossils, and other natural archives of the past. Contextualizing conservation problems on timescales beyond years or decades presents the opportunity to tell different stories about how biodiversity is currently changing and equips conservationists with the conceptual toolkit necessary for unshifting previously unrecognized shifted baselines by changing when the story starts. Geohistorical data sets thus provide an opportunity to restore lost environmental memory-collective observations or records of past environments-and avoid unintended biases. When the ethics, potential outcomes, and diversity of backgrounds and beliefs represented in each audience are considered, incorporating the past can result in compelling stories with the power to engage and persuade an individual or community to support conservation goals while maintaining credibility and trust. An inclusive storytelling approach anchored by geohistorical data may help conservationists tell stories more effectively in the service of identifying or adapting specific conservation goals. These new perspectives (provided by starting stories with new temporal baselines) may also bring new people to the discussion table and allow for a broader range of entry points to conversations and, thus, potential conservation actions.</p>","PeriodicalId":10689,"journal":{"name":"Conservation Biology","volume":" ","pages":"e70057"},"PeriodicalIF":5.2,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144157251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used citizen science data from the Nigerian Bird Atlas Project (2015-2024) and the human footprint index (HFI) from the Socioeconomic Data and Applications Center (SEDAC) to analyze avian taxonomic and functional richness and diversity across 146 paired pentads (5' × 5' grid cells). Each protected area pentad (PAP) that covered ≥70% of a PA was paired with an unprotected pentad (UPP). Bayesian hierarchical models were applied to assess avian taxonomic and functional richness and diversity between PAPs and UPPs and to examine the influence of human activity on these community metrics based on HFI values. The PAPs had higher taxonomic richness and diversity than UPPs. In contrast, abundance-weighted functional diversity metrics (Rao's Q, functional dispersion, and divergence) were higher in UPPs than PAPs due to the proliferation of disturbance-tolerant generalist species. However, functional richness was lower in UPPs than PAPs, reflecting fewer ecological niches. Taxonomic and functional richness increased with moderate human impact, consistent with the intermediate disturbance hypothesis, but declined under higher levels of disturbance, suggesting a point beyond which species cannot adapt or persist. These findings support the critical role of PAs in conserving avian species and functional traits and highlight the effects of human impact on species survival.

We used online reports of seized shipments of seahorses (Hippocampus spp.) to investigate their illegal trade. Seahorses were the first genus of marine fishes to be listed under CITES. We compiled 297 unique seizure records from 192 online outlets posted from January 2010 to April 2021 and analyzed the number of seahorses seized, the value of the seized items, trade routes, and other seizure details. Dried seahorses accounted for nearly all seizures, which totaled around 5 million individuals valued at over US$28 million. The reported number of seizures and the number of seahorses seized increased over time. Reported illegal trade involved 62 countries and other jurisdictions. Seized seahorses predominantly originated in Africa, Asia, and Latin America. China was the primary destination. Seahorses were mostly intercepted in transit and in destination countries rather than source countries. Airports were the most common location for seizures, and passenger baggage represented the primary transportation method by number of seizures, but sea cargo facilitated the largest seizures. Seahorses were most commonly seized by customs, often in conjunction with other regulated wildlife products. Although seizures led to detention of actors, information on subsequent legal actions was limited.

We also examined the impacts of the Corn Belt relative to the Gulf of Mexico on the stopover behavior of migrating birds by comparing changes in the proportion of migrants that stop to rest (stopover-to-passage ratio [SPR]) relative to distance from both barriers. Birds showed increased meridional airspeeds and stronger selection for tailwinds when crossing the Corn Belt compared with forested landscapes. For birds crossing the Gulf of Mexico, the highest proportion of migrants stopped to rest after crossing the Gulf, and SPR decreased sharply as distance from the shoreline increased. We did not find this pattern after migrants crossed the Corn Belt, although the SPR increased in the Corn Belt as birds approached the down-route forest boundary in both seasons. This weaker pattern for stopover propensity after crossing the Corn Belt is likely due to its narrower width, the availability of small forest patches throughout the Corn Belt, and the subset of species affected, compared with the gulf.
