Phylogenetic structure of conifers in regional floras in relation to climate and environmental heterogeneity worldwide

open access: yesEcography, EarlyView.
Despite having only about 670 species worldwide, conifers are one of the ecologically and economically most important plant groups. They have a rich fossil record and previous studies have shown that their current diversity is the result of past radiations, extinction, and dispersal events, restricting many genera to either the Northern or Southern ...

Estuarine benthic diversity declines with temperature across a tropical–temperate gradient

open access: yesEcography, EarlyView.
Estuarine benthic sediments are important habitats that support ecosystem health and productivity, but the drivers of large‐scale patterns in benthic diversity are not well documented. Using 18S amplicon sequencing of 425 sediment DNA samples from estuaries spanning 20° of latitude along Australia's east coast, we assessed tropical–temperate patterns ...

Human pressure, habitat heterogeneity and species traits jointly determine the level of dark diversity in coastal fish communities

open access: yesEcography, EarlyView.
Understanding how anthropogenic pressures and environmental gradients shape coastal fish communities is a central question in biogeography and marine conservation. Yet, the set of species expected to occur at a site given ecological conditions but being absent – the so‐called dark diversity – has received far less attention than observed species, even ...

Global distribution of avian plumage coloration and patterning: the relative influence of climate, ecology, and sexual selection

open access: yesEcography, EarlyView.
Animal coloration exhibits substantial biogeographic variation, reflecting complex adaptations to both abiotic and biotic environments. Although the evolutionary mechanisms underlying avian plumage coloration have been widely studied, geographic variation in plumage patterning has received far less attention.

Asymmetric species turnover underpins the latitudinal diversity gradient in the Western Ghats biodiversity hotspot of India

open access: yesEcography, EarlyView.
Latitudinal diversity gradients (LDGs), namely an increase in species richness from higher to lower latitudes, are one of ecology's best documented patterns, yet how the fundamental components of compositional mismatches (i.e. species gains and losses along a gradient) explain these patterns remains poorly understood.
