A new study by Whitehead and colleagues found that sperm whales off the Galápagos became more tolerant of research vessels used for photoidentification over time. This habituation improved photo quality and suggests limited negative impacts from the research process.

A new study by Alexandra DiGiacomo, @makaira1.bsky.social and colleagues used drone imagery and computer vision to measure eastern Pacific white sharks, revealing size-based habitat use, unusually high body condition, and stronger girth growth in females across life stages.
A new study by McClaran Shirley and Amber Dawn Stubler found that most cryptic marine gastropods in Hawai’i showed stable shell morphology over decades of environmental change, though some species exhibited significant declines.
A new study by Huang and Kobryn shows that mutating just two amino acids can convert the bacterial telomere resolvase TelA into a Cre-like site-specific recombinase. The finding reveals a surprisingly simple route for switching enzyme function.
Boltz and colleagues use trait similarity networks to identify ecological strategies linked to extinction risk in 968 butterfly and moth species in Great Britain and Ireland. Species with multivoltine, externally developing life histories were disproportionately threatened.
A new study by Loktu and colleagues shows how warming Arctic permafrost is accelerating the deterioration of a historic whaling burial site in Svalbard. The remains also reveal the physical toll of early modern whaling, including stress, disease, and heavy labour.

A new study by Loconsole and colleagues found that newly hatched chicks use at least two distinct mechanisms to judge quantity. Depending on experience, they can prefer larger groups or respond to perceptual patterns such as the asymmetry of prime-numbered sets.

A new study by Mariani and colleagues shows that reflectance spectroscopy can rapidly predict several key leaf traits in wine grapes, capturing fine-scale differences among cultivars and offering a high-throughput tool for crop monitoring and management.
A new study by Anele and colleagues mapped Xenopus frogs and their helminth parasites across Nigeria, identifying 5 frog species and 13 parasite species. The work reveals patterns of host specificity, ecological distribution, and tissue specialization.
A new study by Palacios-Martínez and colleagues finds that most winter roosts of Western jackdaws in the Iberian Peninsula are shared with other bird species. These interspecific associations vary with habitat and human influences, shaping roost size and social dynamics.

Wildlife research has the potential to affect the subject animals. These effects can be problematic from ethical and management perspectives, as well as for the effectiveness of the research process…

Trait-based analyses of extinction risk often examine individual traits independently, which can obscure how combinations of traits define broader ecological strategies. Here, we apply a…
Rapid Arctic warming is accelerating the degradation of permafrost-preserved archaeological sites, threatening both cultural heritage and the scientific information it contains. Early modern whaling…
In research on animal numerical cognition, newly hatched domestic chicks have been shown to rely on distinct strategies when confronted with quantitative choices. In some conditions, such as after…

Estimating crop trait data is critical for predicting crop responses to environmental change, enabling more informed diagnoses of crop performance and the development of on-farm management…
Communal roosting in birds often involves complex interspecific interactions influenced by ecological, social, and environmental factors. We examined winter roosts (n = 232) of western jackdaws…

African clawed frogs (Xenopus species) are distributed across sub-Saharan Africa, live in water, and are hosts to diverse parasites whose distributions and host-specificities are incompletely…
Hairpin telomere resolvases comprise a family of enzymes that produce the hairpin (hp) telomeres of bacteria and their phages that possess linear chromosomes and plasmids terminated by covalently…
Natural history collections are a valuable tool to assess the effects of broad-scale and long-term environmental change on a diverse assemblage of species. Measurements from species that have been…

Body size is a fundamental property of animal physiology, growth, and maturation, yet field measurements remain difficult to acquire for large-bodied, highly mobile marine species such as white…
