Community‐driven variations in snow algae color modulate snow albedo reduction

New Phytologist, Volume 249, Issue 4, Page 1739-1752, February 2026.
Summary Snow algae blooms visibly alter snow color and surface energy balance, yet the biological basis of this variability remains unclear. We investigated how pigment composition and community structure shape the optical properties of snow algae blooms of distinct colors – red, orange, and green – co‐occurring within the same snowfield in Glacier ...

Landscape and crop diversity contributes to greater yield stability

Journal of Applied Ecology, Volume 62, Issue 11, Page 3092-3104, November 2025.
These findings underscore the importance of promoting crop diversity and maintaining heterogeneous agricultural landscapes, particularly in pollinator‐dependent crops. Promoting diverse agricultural landscapes with balanced heterogeneity can enhance the resilience of agricultural systems to climate change and contribute to long‐term food security ...

Thermal tolerance is linked to anatomical but not morphological leaf traits in woody species of Andean tropical montane forests

Functional Ecology, Volume 39, Issue 6, Page 1537-1549, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The world is experiencing a rise in global temperatures as a result of climate change. Higher temperatures along with more frequent heat waves negatively impact physiological levels and ultimately lead to plant death.

Behind the lenses: Biases in the contribution of wildlife photography to biodiversity representation

People and Nature, Volume 7, Issue 2, Page 541-556, February 2025.
Abstract Nature‐related visual media has a significant impact on today's society by engaging the public in conservation problems and promoting pro‐environmental behaviours. Although major attention has been paid to how some types of visual media (e.g. documentaries) offer unrealistic portrayals of the natural world, biases on representation by wildlife

Biodistance Analysis via Dental Phenotypic Diversity in Early Collective Burials at Cerro Juan Díaz, Panamá (30–650 CE) [Análisis de Biodistancia Mediante la Diversidad Fenotípica Dental en los Entierros Colectivos Tempranos del Cerro Juan Díaz, Panamá (30–650 EC)]

American Journal of Biological Anthropology, Volume 186, Issue 1, January 2025.
PCoA plot showing biodistance by age at the Cerro Juan Díaz site in Central Panamá. ABSTRACT Objectives Burial space reuse and prolonged interaction with the dead were common practices in the Isthmo‐Colombian Area, dating back to at least the Early Ceramic Period in the Greater Coclé region.

Differential responses of community‐level functional traits to mid‐ and late‐season experimental drought in a temperate grassland

Journal of Ecology, Volume 112, Issue 10, Page 2292-2306, October 2024.
These findings suggest that functional trait composition of grassland communities may shift under climate change‐induced drought, depending on the growing season timings. Trait‐based attempts to predict ecosystem functioning must account for such temporal variation in community trait values.

Physiological thermal niches, elevational ranges and thermal stress in dendrobatid frogs: An integrated approach

Journal of Biogeography, Volume 51, Issue 10, Page 1880-1893, October 2024.
Abstract Aim We investigated the relationship between thermal physiology, elevational distribution and thermal stress among nine closely related dendrobatid frogs during their aquatic stage by employing an integrated approach, combining thermal physiology, environmental temperature modelling and predictive assessments of current and future exposure to ...
