Anatolian ground squirrel (Spermophilus xanthoprymnus) retina: Comparative expression of synaptophysin, NeuN, calbindin‐D28k, parvalbumin, glial fibrillary acidic protein, and Iba‐1 during pre‐hibernation and hibernation

open access: yesThe Anatomical Record, Volume 309, Issue 2, Page 451-470, February 2026.
Abstract Hibernation induces significant molecular and cellular adaptations in the retina to maintain function under reduced metabolic conditions. This study aimed to investigate the expression of neuronal, synaptic, and glial markers in the retina of Spermophilus xanthoprymnus during pre‐hibernation and hibernation periods using immunohistochemical ...

Selfish or altruistic? An analysis of alarm call function in wild capuchin monkeys, Cebus apella nigritus [PDF]

open access: yes, 2008
Alarm calls facilitate some antipredatory benefits of group living but may endanger the caller by attracting the predator's attention. A number of hypotheses invoking kin selection and individual selection have been proposed to explain how such behaviour

Leopards Exhibit Nuanced Predation Patterns but Rely on Wild Prey in a Human‐Dominated Agricultural Landscape in the Central Highlands of Sri Lanka

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
The Sri Lankan endemic subspecies of leopard (Panthera pardus kotiya) is facing intensifying human–leopard interactions in unprotected highlands, from where 107 scat samples indicated its wide‐ranging diet of 17 prey species, the black‐naped hare (Lepus nigricollis) being the favorite, while medium‐sized prey such as barking deer (Muntiacus malabaricus)

Hibernation Shifts in Gut Microbiota Composition and Metabolic Function in the Chinese Horseshoe Bat (Rhinolophus sinicus)

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
The composition and dynamics of gut microbial community structure in Rhinolophus sinicus, employing 16S rRNA amplicon sequencing, are conducted to investigate the effects of physiological status (winter hibernation versus summer activity) on gut microbiota composition.

Indigenous Management Practices to Reduce Pests and Pathogens of Cash Crops in Agroforestry Systems

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
The crop with the highest damages was cocoa (63.9% plants affected by black pod disease), followed by Fusarium stem rot was the second highest damage in crops (30.0% of vanilla plants infected). Insecticides and fungicides do not have a significant impact in reducing pest and pathogen infestation.

A perspective on color vision in platyrrhine monkeys [PDF]

open access: yes, 1960
Studies carried out over the past two decades show that many platyrrhine (New World) monkeys have polymorphic color vision. This condition results from the sorting of allelic versions of X-chromosome cone opsin genes at a single gene site, yielding a ...

Forest structure and connectivity drive the functional recovery of seed rain

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
Local forest structure and landscape‐scale connectivity shape distinct but complementary pathways of the functional recovery of seed rain in tropical forests. Structural complexity promotes functionally diverse plant–frugivore interactions locally, while connectivity facilitates the arrival of late‐successional seeds from external sources.
