The Implications of Incongruence between Gene Tree and Species Tree Topologies for Divergence Time Estimation.
Phylogenetic analyses are increasingly being performed with data sets that incorporate hundreds of loci. Due to incomplete lineage sorting, hybridization, and horizontal gene transfer, the gene trees for these loci may often have topologies that differ from each other and from the species tree. The effect of these topological incongruences...Carruthers, Tom ; Sun, Miao ; Baker, William J. ; Smith, Stephen A. ; de Vos, Jurriaan M. …

Estimating Alpha, Beta, and Gamma Diversity Through Deep Learning.
The reliable mapping of species richness is a crucial step for the identification of areas of high conservation priority, alongside other value and threat considerations. This is commonly done by overlapping range maps of individual species, which requires dense availability of occurrence data or relies on assumptions about the presence...Machine learning, Neural network, Species richness, Biodiversity, Plant, Australia, Deep learning, and Diversity pattern

Integrating deep-time palaeontology in conservation prioritisation.
Halting biodiversity loss under growing anthropogenic pressure is arguably the greatest environmental challenge we face. Given that not all species are equally threatened and that resources are always limited, establishing robust prioritisation schemes is critical for implementing effective conservation actions. To this end, the International Union for Conservation of Nature...Pimiento, Catalina ; Antonelli, Alexandre

The origin and evolution of open habitats in North America inferred by Bayesian deep learning models.
Some of the most extensive terrestrial biomes today consist of open vegetation, including temperate grasslands and tropical savannas. These biomes originated relatively recently in Earth’s history, likely replacing forested habitats in the second half of the Cenozoic. However, the timing of their origination and expansion remains disputed. Here, we present...Andermann, Tobias ; Strömberg, Caroline A. E. ; Antonelli, Alexandre ; Silvestro, Daniele

Improving biodiversity protection through artificial intelligence.
Over a million species face extinction, highlighting the urgent need for conservation policies that maximize the protection of biodiversity to sustain its manifold contributions to people’s lives. Here we present a novel framework for spatial conservation prioritization based on reinforcement learning that consistently outperforms available state-of-the-art software using simulated and... -

The fate of Holoregmia, a monospecific genus endemic to the Brazilian Caatinga, under different future climate scenarios.
– Climatic fluctuations during the Pleistocene altered the distribution of many species and even entire biomes, allowing some species to increase their range while others underwent reductions. Recent and ongoing anthropogenic climate change is altering climatic patterns very rapidly and is likely to impact species’ distributions over shorter timescales than... -

Madagascar’s extraordinary biodiversity: Evolution, distribution, and use.
Madagascar’s biota is hyperdiverse and includes exceptional levels of endemicity. We review the current state of knowledge on Madagascar’s past and current terrestrial and freshwater biodiversity by compiling and presenting comprehensive data on species diversity, endemism, and rates of species description and human uses, in addition to presenting an updated... -

Madagascar’s extraordinary biodiversity: Threats and opportunities.
Madagascar’s unique biota is heavily affected by human activity and is under intense threat. Here, we review the current state of knowledge on the conservation status of Madagascar’s terrestrial and freshwater biodiversity by presenting data and analyses on documented and predicted species-level conservation statuses, the most prevalent and relevant threats,... -

Emergence of methicillin resistance predates the clinical use of antibiotics.
The discovery of antibiotics more than 80 years ago has led to considerable improvements in human and animal health. Although antibiotic resistance in environmental bacteria is ancient, resistance in human pathogens is thought to be a modern phenomenon that is driven by the clinical use of antibiotics . Here we... -

Certification of açaí agroforestry increases the conservation potential of the Amazonian tree flora.
The harvesting of açaí berries (palm fruits from the genus ) in Amazonia has increased over the last 20 years due to a high local and global market demand and triggered by their widely acclaimed health benefits as a ‘superfood’. Although such increase represents a financial boom for local communities,...Damasco, Gabriel ; Anhalt, Mandy ; Perdiz, Ricardo O. ; Wittmann, Florian ; de Assis, Rafael L. …

First evidence of a monodominant (Englerodendron, Amherstieae, Detarioideae, Leguminosae) .tropical moist forest from the early Miocene (21.73 Ma) of Ethiopia
Many tropical wet forests are species-rich and have relatively even species frequency distributions. But, dominance by a single canopy species can also occur in tropical wet climates and can remain stable for centuries. These are uncommon globally, with the African wet tropics supporting more such communities than the Neotropics or... -

Endophytic fungi related to the ash dieback causal agent encode signatures of pathogenicity on European ash
Tree diseases constitute a significant threat to biodiversity worldwide. Pathogen discovery in natural habitats is of vital importance to understanding current and future threats and prioritising efforts towards developing disease management strategies. Ash dieback is a fungal disease of major conservational concern that is infecting common ash trees, , in... -

Estimation of species divergence times in presence of cross-species gene flow.
Cross-species introgression can have significant impacts on phylogenomic reconstruction of species divergence events. Here, we used simulations to show how the presence of even a small amount of introgression can bias divergence time estimates when gene flow is ignored in the analysis. Using advances in analytical methods under the multispecies...Tiley, George P ; Flouri, Tomás ; Jiao, Xiyun ; Poelstra, Jelmer W. ; Xu, Bo …
