This study shows that Aiptasia oral regeneration is faster in symbiotic anemones, suggesting symbiont-derived photosynthates support regeneration.

The paper reanalyzes molecular data suggesting that Aedes nr. albopictus is conspecific with Aedes pseudalbopictus, challenging the classification of a putative cryptic species.

This study assesses shark and ray bycatch at two key landing sites in Bangladesh, revealing high juvenile and female proportions and highlighting conservation challenges.

In Tororo, Uganda, An. funestus tolerated clothianidin-sprayed walls better than An. gambiae yet was killed on pirimiphos-methyl walls up to 7 months post-spray, implicating it in the malaria resurgence.

This study compares divergent and parallel selection in Amazonian and Andean bird species, finding that parallel selection drove faster evolutionary change during glacial cycles.

DESS (DMSO/EDTA/saturated NaCl) kept DNA at room temperature in animals, seagrasses and a brown alga, even after evaporating from bird muscle, but dissolves gastropod shells and holothurian ossicles.

This study examines the archaeological record of the Arenal Central site, revealing the Guarani occupation of the Parana Delta and their adaptation strategies in a resource-limited environment.

This study evaluates the efficacy of oxalic acid and other miticides combined with adjuvants in reducing Varroa destructor mites in honey bee colonies.

Gait-space clustering shows juvenile tarantulas losing two same-tetrapod legs immediately adopt variable tripod-like gaits, regaining pre-autotomy speed within a day without evidence of learning.

The paper identifies ttc39bl as the gene responsible for carotenoid coloration in medaka, showing a mutation in the X chromosome causes white body color.

The paper identifies five kdr mutations in Indian Ae. aegypti populations and finds no recombination among haplotypes with V1016G, F1534C, and F1534L alleles.

This review evaluates the lack of studies on the sympatric Syrian and Great Spotted Woodpeckers, emphasizing the need to consider co-occurrence and hybridization in their ecology and biology.

The paper describes jaw muscles and calculates bite force in South American opossums using manual and virtual dissection methods, comparing results and highlighting differences in muscle anatomy and PCSA calculation.

The paper creates AvianLexiconAtlas, a database categorizing English bird common names into biological or cultural descriptors, finding 89% of names relate to biology/ecology.

This paper uses predictive models to show that profile drag drives avian flight kinematic trends across scales, explaining speed, frequency, and energy efficiency patterns.

The paper shows Saimaa ringed seals originated 60,000 years ago, long before their lake habitat formed, and have distinct adaptive traits.

This study shows that dietary n-3 PUFA improves dry matter intake in transition cows by altering liver gene expression related to taste transduction and modifying rumen microbial composition.

This study examines how mammals in the Julian Prealps respond to predation risk through habitat selection, activity timing, and behavioral changes, finding that diel activity adjustments are the primary response.

This study shows X-ray irradiation impairs flight in Cydia pomonella male moths by disrupting energy metabolism, and suggests decanoic acid and citric acid can restore flight capacity.

This study uses DNA analysis from a century-old holotype to resolve taxonomic uncertainties of the coral species Pleurocorallium secundum, confirming its identity and clarifying its distribution and misidentified specimens.
