The family Pteropodidae (Old World fruit bats) comprises >200 species distributed across the Old World tropics and subtropics. Most pteropodids feed on fruit, suggesting an early origin of frugivory, although several lineages have shifted to nectar-based diets. Pteropodids are of exceptional conservation concern with >50% of species considered threatened, yet the systematics of this group has long been debated, with uncertainty surrounding early splits attributed to an ancient rapid diversification. Resolving the relationships among the...

Restoration interventions mediate tropical tree recruitment dynamics over time

Andy Kulikowski, Rakan Zahawi, Kai Zhu, Leland Werden & Karen Holl
Forest restoration is increasingly heralded as a global strategy to conserve biodiversity and mitigate climate change, yet long-term studies that compare the effects of different restoration strategies on tree recruit demographics are lacking. We measured tree recruit survival and growth annually in three restoration treatments ‒ natural regeneration, applied nucleation, and tree plantations ‒ replicated at 13 sites in southern Costa Rica, and evaluated the changes over a decade. Early-successional seedlings had 14% higher survival...

Adaptation across geographic ranges is consistent with strong selection in marginal climates and legacies of range expansion

Megan Bontrager, Takuji Usui, Julie Lee-Yaw, Daniel Anstett, Haley Branch, Anna Hargreaves, Christopher Muir & Amy Angert
Every species experiences limits to its geographic distribution. Some evolutionary models predict that populations at range edges are less well-adapted to their local environments due to drift, expansion load, or swamping gene flow from the range interior. Alternatively, populations near range edges might be uniquely adapted to marginal environments. In this study, we use a database of transplant studies that quantify performance at broad geographic scales to test how local adaptation, site quality, and population...

Horizontal Stirring over the Northeast U.S. Continental Shelf: the Spatial and Temporal Evolution of Surface Eddy Kinetic Energy

Visualizing active viral infection reveals diverse cell fates in synchronized algal bloom demise

Flora Vincent, Uri Sheyn, Daniella Schatz, Ziv Porat & Assaf Vardi
Marine viruses are the most abundant biological entity in the ocean and are considered as major evolutionary drivers of microbial life (Suttle, 2007). Yet, we lack quantitative approaches to assess their impact on the marine ecosystem. Here, we provide quantification of active viral infection in the bloom forming single celled phytoplankton Emiliania huxleyi infected by the large virus EhV, using high-throughput single molecule mRNA in situ hybridization of both virus and host transcripts. In natural...

Speciation in the abyss - genomics and morphology reveal a new species of beaked whale

Onoufriou, Robin W. Baird, C. Scott Baker, Simon Berrow, Danielle Cholewiak, Diane Claridge, Rochelle Constantine, Nicholas J. Davison, Catarina Eira, R. Ewan Fordyce, John Gatesy, G. J. Greg Hofmeyr, Vidal Martin, James G. Mead, Antonio A. Mignucci-Giannoni … & Morten T. Olsen
Earth’s deep oceans remains less well understood than the surface of Mars. Beaked whales (ziphiids) are among the most visible inhabitants of the abyss, due to their large size and worldwide distribution, yet their diversity and ecology remain obscure. We combine genomic and morphometric analyses to reveal a new Southern Hemisphere ziphiid species, Ramari’s beaked whale, Mesoplodon eueu, whose name is linked to the Indigenous people of the lands from which the species holotype and...
