Functional Morphology of the Scaphoid in Extant African Apes, Humans and Fossil Hominins. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives The morphology of the hominoid scaphoid has played a key role in functional and evolutionary hypotheses related to the emergence of hominin bipedalism and tool use. However, the scaphoid's complex morphology is challenging to comparatively analyze via traditional 2D linear measurements.

Beyond species means - the intraspecific contribution to global wood density variation. [PDF]

New Phytol
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Urban Tree Growth and Drought Responses Show Evidence of Climate Resilience. [PDF]

Glob Chang Biol
Urban trees face increasing risks from climate change, including drought and heatwaves, which threaten their growth and survival. By studying 10 tree species across seven Australian cities, we found that local climate strongly influences tree growth, and that some species are well adapted to urban climates.

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities

Conservation Biology, EarlyView.
Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

Maximum water stress is decoupled from climate, traits, and growth in a xeric oak

New Phytologist, EarlyView.
We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

Which, when, and where traits matter: functional trait‐mediated species associations shift with microenvironmental and climatic variation

New Phytologist, EarlyView.
Community‐level fitted relationship between spatial association Lij and trait dissimilarity (tDij) at the fine spatial scale (r = 40 mm; where r represents the radius around individuals of the focal species). Summary Predicting coexistence in species‐rich plant communities requires understanding the role of functional traits in species interactions and

Functional homogenization of terrestrial mammals outside protected areas in the Hengduan Mountains, China

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...
