Capsule: Studies of nest predation using artificial nests need to consider the effect egg size on types predator that are detected.Aims: To estimate rate in Patagonian temperate forest and evaluate influence guild.Methods: On different plant species, we placed 108 each containing eggs either Atlantic Canary Serinus canaria or Common Quail Coturnix coturnix, a model clay equal real egg. Nest predators were identified from marks left by videos recorded camera traps.Results: 86% predated....
Predation is the main cause of nest failure among birds. Habitat characteristics play a critical role in affecting predation by modifying conspicuousness and ease access to predators. Here, using artificial nests containing canary egg model clay we examined compared rates principal predators three different Patagonian forest stand types. Also, evaluated how vegetation cover height affected We found lower evergreen than deciduous forests, suggesting type as key factor modulating risk...
The distribution of a species reflects its ecological adaptability and evolutionary history, which is shaped by the environment represents dynamic area subject to anthropogenic environmental change. We used MaxEnt algorithm construct niche models for four thrush within Turdus genus; T. amaurochalinus, chiguanco, falcklandii rufiventris. These were predict potential geographic distributions these that are expanding their ranges in South America. Using occurrence records, we estimated...
Abstract The Austral Opossum is one of the most unique vertebrates in Patagonian forests. It not only endemic to this habitat; it also plays a key role acting as seed disperser, nest predator, and prey species conservation concern. However, specific information about its nesting behaviour scattered rudimentary at best. Here, we: (i) use personal observations along with published data group site choice (ii) investigate how flexible is, examining relative frequency both cavity (natural...
Multiple factors influence predation risk, ranging from habitat conditions to the composition and behaviour of predators. Although these are well documented for forest ecosystems, there is little evidence wetlands, especially within Patagonia. Using artificial nests camera traps, we nest rates predator assemblage birds nesting in wetlands Patagonian steppe. We also determined effect vegetation cover on survival studied variation groups according placement: located an open wetland, peripheral...
Abstract Deer abundance and occupancy areas are currently increasing worldwide, with unknown consequences for birds. impacts on birds have mainly been assumed to be indirect through mechanisms that negatively influence vegetation complexity reduce habitat quality. Information the direct negative bird breeding success is scattered rudimentary. Here we documented, videos filmed camera traps, non‐native deer preying nests. We supported this finding by investigating nest predator behaviour in...
Abstract The widespread human activity on Earth exerts strong selective pressures the species with which we coexist. Faced constant environmental change, respond mechanisms of adaptation, expansion, retraction or displacement. Species that establish new populations outside their former range as a result human-induced change are called 'neonatives'. Many birds now appear to be expanding ranges in response habitat modification and climate change. In this study, use data from three citizen...
Nest predation is one of the most important selection pressures for birds; so, choice nesting site key to chick survival. We experimentally evaluated if presence thorns in shrubs contributes protection against nest predation. The work was developed near city San Carlos de Bariloche, Argentina, a Patagonian steppe environment. placed artifcial nests on rose mosqueta shrubs, varying density thorns, and naturally free thorns. general rate around 90% not affected by Possible causes thorny as...
Abstract Aim Several geological events affecting Southern South America during the middle Miocene climatic optimum acted as important drivers of diversification to biota. This is case Microbiotheria, for which Dromiciops considered sole surviving lineage, sister group Eomarsupialia (Australian marsupials). Three main genetic lineages are known, whose divergence was initially attributed recent Pleistocene glaciations. Using fossil-calibrated dating on nuclear and mitochondrial genes, here we...
