Shape‐shifting in relative wing length of juvenile shorebirds: no evidence of developmental temperatures driving morphological changes Ecography (IF 5.4) Pub Date : 2025-06-12 Sara Ryding, Alexandra McQueen, Matthew R.E. Symonds, Glenn J. Tattersall, Victorian Wader Study Group, Australasian Wader Studies Group, Danny I. Rogers, Robyn Atkinson, Roz Jessop, Chris J. Hassell, Maureen Christie, Tobias A. Ross, Marcel Klaassen
Morphological changes concurrent with climate change are increasingly identified in birds, often through decreasing body size and increasing appendage size. Such changes could have thermoregulatory implications, through the improved surface area to body ratio they provide. Due to the role of bird wings in thermoregulation, wing length relative to body mass may be changing as another form of shape‐shifting

Dissecting earthworm diversity in tropical rainforests Ecography (IF 5.4) Pub Date : 2025-03-04 Arnaud Goulpeau, Mickaël Hedde, Pierre Ganault, Emmanuel Lapied, Marie-Eugénie Maggia, Eric Marcon, Thibaud Decaëns
Tropical rainforests are among the most emblematic ecosystems in terms of biodiversity. However, our understanding of the structure of tropical biodiversity is still incomplete, particularly for certain groups of soil organisms such as earthworms, whose importance for ecosystem functioning is widely recognised. This study aims at determining the relative contribution of alpha and beta components to

Species that dominate spatial turnover can be of (almost) any abundance Ecography (IF 5.4) Pub Date : 2025-03-04 David C. Deane, Cang Hui, Melodie McGeoch
An ongoing quest in ecology is understanding how species commonness influences compositional change. While each species' contribution to beta diversity (SCBD) depends both on its abundance and how widespread it is (e.g. occupancy) a general expectation for these influences is lacking. Using published data for 9924 species across 177 metacommunities, we modelled relative SCBD as a function of abundance

Latitudinal patterns and climatic drivers of Laurasian and Gondwanan angiosperm tree distributions in forests of the Americas Ecography (IF 5.4) Pub Date : 2025-02-19 Yi Jin, Hong Qian
The biogeographic affinity of a lineage leaves imprint on its niche, and influences its distribution under biotic interchange between landmasses. Since the beginning of the Quaternary, North America (a remnant of Laurasia) and South America (a remnant of Gondwana) have been united, and triggered the Great American Biotic Interchange. Based on existing knowledge, we expect more Laurasian lineages to

Does habitat or climate change drive species range shifts? Ecography (IF 5.4) Pub Date : 2025-02-17 Toni L. Morelli, Michael T. Hallworth, Timothy Duclos, Adam Ells, Steven D. Faccio, Jane R. Foster, Kent P. McFarland, Keith Nislow, Joel Ralston, Mary Ratnaswamy, William V. Deluca, Alexej P. K. Siren
A primary prediction of climate change ecology is that species will track their climate niche poleward and upslope. However, studies have shown species responding in surprising ways. In this study, we aim to understand the impact of global change on species ranges by considering both climate and habitat changes. Using occupancy analysis of acoustic survey data in the mountains of the northeastern United
