“…This is due to the presence of riparian forests, which provide humid habitats for the species to occur. Previous SDM studies have highlighted the DD as a barrier for forest taxa with a disjunct distribution in the AM and AF (Batalha‐filho et al., 2013; da Silva et al., 2019, 2020; do Nascimento et al., 2021; Silva et al., 2023). However, when considering SDM projections for the past, it is noteworthy that the region has become more climatically favourable in some periods, particularly at the LGM.…”

An open and dry vegetation belt separates Amazonia (AM) and the Atlantic Forest (AF). Evidence from palaeoclimatic and phylogenetic studies suggests past connections between these forests during cycles of increased humidity through the formation of forest corridors. The distinctive northern AF avifauna is known to have affinities both with AM and the southern AF. Still, the extent of how these two regions contributed to the assemblage of this avifauna remains poorly understood. Using historical demographic analyses and comparative phylogeography based on sub‐genomic genetic sampling, we assessed how past connections between AM and AF led to shared vicariance and colonization events in four avian AF endemic taxa. Our results supported the occurrence of humid forest corridors promoting the contact between AF and AM populations and suggested two vicariant events and two colonization events from AF to AM. Population divergences were mostly non‐synchronous and occurred multiple times during the Pleistocene. Historical gene flow was prevalent across study groups, supporting migration flows after the initial separation between AM and AF – a pattern previously unknown in birds between these regions. Idiosyncratic histories and divergent demographic syndromes suggest that organisms' responses to climate‐driven habitat shifts broadly depend on their ecological attributes. This study strengthened our knowledge of past connections between AM and AF and provided demographic scenarios amenable for testing in other groups of co‐distributed organisms.

“…SDMs play a crucial role in addressing the Wallacean shortfall by providing unbiased and easily interpretable estimates of species distribution information (Moonlight et al., 2020 ). They improve the accuracy and range of species distributions by incorporating ecological data such as climate and functional traits, along with fine‐scale aggregated data like specimen records, surveys, and experiments (López‐Aguilar et al., 2024 ; Silva et al., 2020 ). SDMs bridge the gap between fine‐scale precision and global representativeness, thus aiding in predicting and conserving biodiversity (Alvarez et al., 2021 ).…”

In recent years, increased species extinction and habitat loss have significantly reduced biodiversity, posing a serious threat to both nature and human survival. Environmental factors strongly influence bird distribution and diversity. The potential distribution patterns and species richness offer a conservation modeling framework for policymakers to assess the effectiveness of natural protected areas (PAs) and optimize their existing ones. Very few such studies have been published that cover a large and complete taxonomic group with fine resolution at regional scale. Here, using birds as a study group, the maximum entropy model (MaxEnt) was used to analyze the pattern of bird species richness in Jiangsu Province. Using an unparalleled amount of occurrence data, we created species distribution models (SDMs) for 312 bird species to explore emerging diversity patterns at a resolution of 1 km2. The gradient of species richness is steep, decreasing sharply away from water bodies, particularly in the northern part of Jiangsu Province. The migratory status and feeding habits of birds also significantly influence the spatial distribution of avian species richness. This study reveals that the regions with high potential bird species richness are primarily distributed in three areas: the eastern coastal region, the surrounding area of the lower reaches of the Yangtze River, and the surrounding area of Taihu Lake. Compared with species richness hotspots and existing PAs, we found that the majority of hotspots are well‐protected. However, only a small portion of the regions, such as coastal areas of Sheyang County in Yancheng City, as well as some regions along the Yangtze River in Nanjing and Zhenjiang, currently have relatively weak protection. Using stacked SDMs, our study reveals effective insights into diversity patterns, directly informing conservation policies and contributing to macroecological research advancements.

An ongoing challenge in evolutionary and ecological research focuses on testing biogeographic hypotheses for the understanding of both species' distributional patterns and of the factors influencing range limits. In this study, we described the climatic niches of Neotropical humid montane forest birds through the analysis of factors driving their evolution at inter‐ and intraspecific levels; and tested for differences among allopatric lineages within Aulacorhynchus, Chlorospingus, Cardellina, and Eupherusa. We employed ecological niche models (ENMs) along with an ordination approach with kernel smoothing to perform niche overlap analyses and test hypotheses of niche equivalence/similarity among lineages. In addition, we described the potential distributions of each lineage during the Late Pleistocene climate fluctuations, identifying historical range expansions, connectivity, and stability. Overall, we observed differences in environmental variables influencing climatic requirements and distributional patterns for our selected species. We detected the highest values of niche overlap mainly between Eupherusa and some Chlorospingus lineages. At both interspecific and intraspecific levels, sister lineages showed non‐identical environmental niches. Our results offer weak support to a moist forest model, in which populations followed the expansion and contraction cycles of montane forests, leading to a lack of niche conservatism among lineages (they tend to occupy not identical climatic environments) throughout Mesoamerica. Therefore, historical climatic conditions may act as ecological barriers determining the distributional ranges of these species.
