Eusocial bee species are exposed to different toxic element profiles despite foraging within the same landscape

Ecological Entomology, Volume 51, Issue 5, Page 912-925, October 2026.
Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.

Hair coat characteristics in Friesian heifers in the Netherlands and Kenya : experimental data and a review of literature [PDF]

, 1978
The export of about 2600 Friesian heifers to Kenya between 1971-1973 provided an opportunity of studying the adaptation problems experienced by these heifers.

Longitudinal genome‐wide aneuploidy measurements in circulating cell‐free DNA to predict lack of benefit from pembrolizumab in patients with metastatic urothelial cancer

Molecular Oncology, Volume 20, Issue 9, Page 2175-2187, September 2026.
Many patients with urothelial cancer do not benefit from treatment with pembrolizumab, while at risk of severe side effects. Changes in the levels of circulating tumor DNA early during treatment, measured by a simple and affordable assay that can be easily implemented in the clinic, can be used as a prognostic tool to identify these patients.

K15 & Id3 expression in intact and regenerating adult vibrissae rodent hair follicles [PDF]

, 2009
The hair follicle can renew itself through an intrinsic stem cell population and has the ability to undergo hair follicle growth cycle; its regenerative activities under normal and experimental conditions together with a feature of easy access make it an

Tree cavities as keystone structures in a semiarid region: Interspecific aggregations of anurans in the Brazilian Caatinga

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Tree cavities function as key microclimatic refuges for anurans in the semiarid Caatinga biome of northeastern Brazil, where we document previously unreported interspecific aggregations during the dry season. Observations from fauna rescue operations preceding vegetation clearance revealed eight distinct aggregations within cavities of two ...

The organization of tip links and stereocilia on hair cells of bird and lizard basilar papillae [PDF]

, 1989
Auditory papillae from three species of bird (pigeon, starling, and chick), and two species of European lizard (Podarcis murolis and Podarcis sic&) were examined by scanning electron microscopy.

Invasive mammals disrupt sea–land nutrient inputs over 169 years on subtropical oceanic islands

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Invasive mammals have severely impacted oceanic islands, reducing or extirpating seabird populations and driving the collapse of nutrient flows with lasting ecosystem effects. We investigated these dynamics on contrasting subtropical oceanic islands in the South Pacific: Rangitāhua, a large island where goats, cats, and rats caused the ...

Ocean Acidification Cannot Mitigate Warming‐Induced Physiological Stress in a Key Foundation Kelp

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Ocean warming and acidification are reshaping coastal ecosystems, but their combined effects on foundation species remain unresolved. Using mesocosm experiments, we tested for the individual and combined effects of ocean warming and acidification on the juvenile kelp Laminaria digitata.

Can't outrun recurrence: Long‐term outcomes of treating American black bear sarcoptic mange

The Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
Abstract The growing incidence of sarcoptic mange in American black bears (Ursus americanus) has become a concern for wildlife managers in the eastern United States. Inconsistency in the use of single and multi‐dose treatment approaches makes it difficult to evaluate their effects on post‐release outcomes of mange‐rehabilitated bears, which remain ...

Insight into the early steps of root hair formation revealed by the procuste1 cellulose synthase mutant of Arabidopsis thaliana [PDF]

, 2008
Background: formation of plant root hairs originating from epidermal cells involves selection of a polar initiation site and production of an initial hair bulge which requires local cell wall loosening. In Arabidopsis the polar initiation site is located
