Cool and Shady: Ecophysiological Preferences of Chrysophytes. [PDF]

J Eukaryot Microbiol
ABSTRACT Chrysophyceae (Stramenopiles) are a diverse group of protists widely distributed in various aquatic habitats, including alpine lakes, where they play key ecological roles. Their nutritional modes—phototrophy, heterotrophy, and mixotrophy—enable them to adapt to the unique light and temperature conditions found across altitudinal gradients in ...

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics. [PDF]

FEBS Open Bio
Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

A Review of the Scale and Sustainability of the Consumption and Trade of Anuran Species in Africa. [PDF]

Ecol Evol
ABSTRACT Within Africa, collection and trade of anurans is often recorded as single‐site case studies, making it difficult to accurately understand the scale of use, its livelihood importance, and impact on species. We conducted a systematic review to: compile literature on anuran uses in Africa; identify the species and ecoregions involved; and ...

Hechtia mixtecana sp. nov. (Hechtioideae; Bromeliaceae), from Oaxaca, Mexico

Nordic Journal of Botany, EarlyView.
Botanical explorations carried out in the state of Oaxaca, Mexico, led to the discovery of a new Bromeliaceae: Hechtia mixtecana,which is here described and illustrated. The new taxon is compared with the morphologically similar Hechtia fragilis, Hechtia lyman‐smithii, and Hechtia minuta.

Hunting, but not outdoor recreation, modulates behavioural tolerance to human disturbance in Alpine marmots Marmota marmota

Wildlife Biology, EarlyView.
Humans are often perceived as predators by free‐living animals, and thus, even non‐consumptive human activities such as outdoor recreation may trigger behavioural and physiological responses, often with negative consequences on individual fitness and population persistence.

A Tale of Appendages: Investigating Limb and Tail Variation in Salamanders

Integrative Zoology, EarlyView.
We analyzed limb and tail proportions in 44% of known salamander species using a phylogenetic comparative approach. Our results revealed significant variation among families and ecological groups, with aquatic species showing longer limbs and basal lineages having shorter tails.

Comparative Study of Sulfated Polysaccharides From Ulva Lactuca Grown in Tunisia and Morocco: in Vitro Antioxidant Activity and in Vivo Anti‐Inflammatory and Anti‐Ulcer Effects

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT This study presents a comparative analysis of sulfated polysaccharides extracted from Ulva lactuca collected in Tunisia (PSUT) and Morocco (PSUM). FTIR confirmed the presence of sulfate groups, while GC‐MS identified diverse sugar components. Both polysaccharides showed strong antioxidant activity, with DPPH and ABTS radical scavenging rates ...

Clashing in Murky Waters: On Amphibian Mosquito Suppression

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study compares the predator efficiency of common European amphibian species to common invertebrate mosquito predators. Focusing on the cosmopolitan mosquito Culex pipiens, known for transmitting pathogens like West Nile virus, we assessed predator rates, sex‐specific efficiency in amphibians, and the impact of predator presence on mosquito ...

Repeated (Weekly) Intra‐Articular Injections of Sulfated Galactans Attenuate Cartilage Degeneration in a Rat Model of Osteoarthritis

Journal of Orthopaedic Research, Volume 44, Issue 3, March 2026.
Knee osteoarthritis (OA) is characterized by progressive cartilage degeneration and remains a major cause of joint dysfunction with limited disease‐modifying therapies. This study evaluated the therapeutic potential of sulfated galactans (SG) extracted from Gracilaria fisheri in a rat OA model induced by anterior cruciate ligament transection and ...

Climate stability drives multidimensional nestedness of amphibian assemblages in a Chinese sky island system

Functional Ecology, Volume 40, Issue 3, Page 636-654, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate
