Interrogating discordance resolves relationships in the rapid radiation of Old World fruit bats (Chiroptera: Pteropodidae)

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...

Timing is everything: Acoustic niche partitioning in two tropical wet forest bird communities

Patrick Hart, Thomas Ibanez, Kristina Paxton & Esthér Sebastián-González
When acoustic signals sent from individuals overlap in frequency and time, acoustic interference and signal masking may occur. Under the acoustic niche hypothesis (ANH), signaling behavior has evolved to partition acoustic space and minimize overlap with other calling individuals through selection on signal structure and/or the sender’s ability to adjust the timing of signals. Alternately, under the acoustic clustering hypothesis, there is potential benefit to convergence and synchronization of the structural or temporal characteristics of...

Evolutionary winners are ecological losers among oceanic island plants

José María Fernández-Palacios, Rüdiger Otto, Michael K. Borregaard, Holger Kreft, Jonathan P. Price, Manuel J. Steinbauer, Patrick Weigelt & Robert J. Whittaker
Aim: Adaptive radiation, in which successful lineages proliferate by exploiting untapped niche space, provides a popular but potentially misleading characterization of evolution on oceanic islands. Here we analyse the respective roles of members of in situ diversified vs. non-diversified lineages in shaping the main ecosystems of an archipelago to explore the relationship between evolutionary and ecological ‘success’. Location: Canary Islands. Taxon: Vascular plants. Methods: We quantified the abundance/rarity of the native flora according to the...

A global ecological signal of extinction risk in terrestrial vertebrates

Maya Munstermann, Noel Heim, Douglas McCauley, Jonathan Payne, Nathan Upham, Steve Wang & Matthew Knope
To determine the distribution and causes of extinction threat across functional groups of terrestrial vertebrates, we assembled a dataset on ecological traits for 18,016 species and tested, using phylogenetic comparative methods, which categories of habitat association, mode of locomotion, and feeding mode best predict extinction risk. We found that cave-dwelling amphibians, brachiating mammals (all of which are primates), aerial and scavenging birds, and pedal squamates are all disproportionately threatened with extinction. Across four vertebrate classes,...
