    Abstract: We know surprisingly little about the fate of seeds of the Brazil nut tree ( Bertholletia excelsa ) under natural conditions. Here we investigate seed removal, predation and caching of Brazil nuts by scatter-hoarding rodents in the wet and dry seasons, based on an experimental approach using 900 thread-marked seeds. We tracked the fate of seeds handled by these animals to examine how seasonal food availability may influence caching rates, dispersal distances and cache longevity. Most seeds exposed to dispersal trials were removed by scatter-hoarders during the first week in both seasons and seeds were generally buried intact in single-seeded caches within 10 m of seed stations. Seeds were removed significantly faster and buried at greater distances during the dry season. The proportion of seeds buried intact was considerably higher in the wet season (74.4%) than in the dry season (38.2%). Most (99.4%) of the 881 primary caches monitored were recovered, but these had a significantly shorter lifetime in the dry season. Our results show that rodents are highly skilled at retrieving buried Brazil nuts and that caching behaviour appears to be affected by seasonal resource abundance. Reduced seed availability due to intensive harvest could potentially create a dry-season scenario where most seeds succumb to pre-dispersal predation, thereby adversely affecting the natural regeneration of Brazil nut trees.

    Abstract: Few studies have contrasted faunal communities between flooded and unflooded tropical forests, and such attempts have largely been restricted to a few taxonomic groups. We present the first comparison of the composition and structure of an entire assemblage of mid-sized to large-bodied mammals in adjacent unflooded (terra firme) and flooded (várzea) forests of central-western Amazonia. We extend this comparison to 13 other terra firme and várzea forest sites in order to examine the fundamental dichotomy between mammal communities in these Amazonian environments. We found a consistently impoverished fauna in várzea environments both in terms of primates and other non-volant mammals, although primate density and biomass was substantially higher in várzea than in terra firme. The average Bray–Curtis mammal community dissimilarity between terra firme and várzea forests was 74%, whereas mean dissimilarity within várzea and terra firme samples was 40% and 39%, respectively. The results seem to be largely a function of high habitat heterogeneity and floristic diversity in terra firme and the physical connectivity and proximity of várzeas to adjacent terra firme forests. We suggest that inundated forests should be set aside as a crucial complement to Amazonian reserves dominated by terra firme forests in future biodiversity conservation planning.

    Abstract: Finding new pathways for reconciling socioeconomic well-being and nature sustainability is critically important for contemporary societies, especially in tropical developing countries where sustaining local livelihoods often clashes with biodiversity conservation. Many projects aimed at reconciling the goals of biodiversity conservation and social aspirations within protected areas (PAs) have failed on one or both counts. Here, we investigate the social consequences of living either inside or outside sustainable-use PAs in the Brazilian Amazon, using data from more than 100 local communities along a 2,000-km section of a major Amazonian river. The PAs in this region are now widely viewed as conservation triumphs, having implemented community comanagement of fisheries and recovery of overexploited wildlife populations. We document clear differences in social welfare in communities inside and outside PAs. Specifically, communities inside PAs enjoy better access to health care, education, electricity, basic sanitation, and communication infrastructure. Moreover, living within a PA was the strongest predictor of household wealth, followed by cash-transfer programs and the number of people per household. These collective cobenefits clearly influence life satisfaction, with only 5% of all adult residents inside PAs aspiring to move to urban centers, compared with 58% of adults in unprotected areas. Our results clearly demonstrate that large-scale “win–win” conservation solutions are possible in tropical countries with limited financial and human resources and reinforce the need to genuinely empower local people in integrated conservation-development programs.

    Wild dogs at stake: deforestation threatens the only Amazon endemic canid, the short-eared dog ( Atelocynus microtis )

    Abstract: The persistent high deforestation rate and fragmentation of the Amazon forests are the main threats to their biodiversity. To anticipate and mitigate these threats, it is important to understand and predict how species respond to the rapidly changing landscape. The short-eared dog Atelocynus microtis is the only Amazon-endemic canid and one of the most understudied wild dogs worldwide. We investigated short-eared dog habitat associations on two spatial scales. First, we used the largest record database ever compiled for short-eared dogs in combination with species distribution models to map species habitat suitability, estimate its distribution range and predict shifts in species distribution in response to predicted deforestation across the entire Amazon (regional scale). Second, we used systematic camera trap surveys and occupancy models to investigate how forest cover and forest fragmentation affect the space use of this species in the Southern Brazilian Amazon (local scale). Species distribution models suggested that the short-eared dog potentially occurs over an extensive and continuous area, through most of the Amazon region south of the Amazon River. However, approximately 30% of the short-eared dog's current distribution is expected to be lost or suffer sharp declines in habitat suitability by 2027 (within three generations) due to forest loss. This proportion might reach 40% of the species distribution in unprotected areas and exceed 60% in some interfluves (i.e. portions of land separated by large rivers) of the Amazon basin. Our local-scale analysis indicated that the presence of forest positively affected short-eared dog space use, while the density of forest edges had a negative effect. Beyond shedding light on the ecology of the short-eared dog and refining its distribution range, our results stress that forest loss poses a serious threat to the conservation of the species in a short time frame. Hence, we propose a re-assessment of the short-eared dog's current IUCN Red List status (Near Threatened) based on findings presented here. Our study exemplifies how data can be integrated across sources and modelling procedures to improve our knowledge of relatively understudied species.

    Abstract: O quase-ameaçado pato-corredor Neochen jubata é um anatídeo sul-americano pouco conhecido e com uma população decrescente devido, principalmente, à intensa pressão de caça. Neste estudo, nós realizamos censos populacionais de patos-corredores ao longo do médio curso do rio Juruá, Amazônia Ocidental Brasileira, e de seus tributários de primeira ordem na região. Nós quantificamos a abundância sazonal de patos-corredores, definimos a época de reprodução e investigamos as associações de habitat e as potenciais influências de atividades humanas em sua abundância. Atividades de caça em comunidades locais foram também monitoradas a fim de avaliar a taxa de abate da espécie. A ocorrência da espécie na região foi acentuadamente sazonal e aparentemente restrita aos meses da estação seca. A taxa de encontro de indivíduos adultos durante essa estação foi estimada em 7.18 ± 2.45 ind/4 km de seção de rio. Indivíduos imaturos foram vistos ao longo das margens do rio e tributários durante o período de agosto-dezembro. A espécie demostrou uma forte preferência por praias arenosas e se mostrou basicamente restrita ao canal principal do rio Juruá, com poucos indivíduos encontrados ao longo dos tributários. A taxa de encontro da espécie foi também significativamente relacionada à distância fluvial do centro urbano municipal e ao nível de proteção de caça. A caça de patos-corredores foi registrada em 12 das 26 comunidades monitoradas. A ocorrência sazonal de pato-corredor na região sugere que essa é uma população migratória. Nosso estudo indica que regras de proteção restritas das margens do rio, e, em particular, das praias arenosas, podem ser benéficas para a conservação desta espécie na bacia do Juruá. No entanto, um melhor conhecimento das rotas migratórias é fundamental para uma proteção efetiva de populações reprodutivas e não reprodutivas.

    Land‐sparing agriculture sustains higher levels of avian functional diversity than land sharing

    Abstract: The ecological impacts of meeting rising demands for food production can potentially be mitigated by two competing land‐use strategies: off‐setting natural habitats through intensification of existing farmland (land sparing), or elevating biodiversity within the agricultural matrix via the integration of “wildlife‐friendly” habitat features (land sharing). However, a key unanswered question is whether sparing or sharing farming would best conserve functional diversity, which can promote ecosystem stability and resilience to future land‐use change. Focusing on bird communities in tropical cloud forests of the Colombian Andes, we test the performance of each strategy in conserving functional diversity. We show that multiple components of avian functional diversity in farmland are positively related to the proximity and extent of natural forest. Using landscape and community simulations, we also show that land‐sparing agriculture conserves greater functional diversity and predicts higher abundance of species supplying key ecological functions than land sharing, with sharing becoming progressively inferior with increasing isolation from remnant forest. These results suggest low‐intensity agriculture is likely to conserve little functional diversity unless large blocks of adjacent natural habitat are protected, consistent with land sparing. To ensure the retention of functionally diverse ecosystems, we urgently need to implement mechanisms for increasing farmland productivity whilst protecting spared land.
