In this study, the life-history traits of are presented for the first time. A total of 27 samples (17 ♂♂ and 10 ♀♀) from Iğdır Province, Türkiye, were aged using skeletochronology. Student's -test was performed to compare mean differences in the variables between sexes. The relationships between age and snout-vent length (SVL) were determined through correlation. Growth patterns were estimated based on the von Bertalanffy equation. Lastly, survival rate and adult life expectancy were calculated for each sex. The mean SVL was 52.93 ± 1.28 mm in males and 46.23 ± 1.55 in females. The mean age was 4.88 ± 0.43 years and 3.20 ± 0.29 years for males and females, respectively. Correlation analysis revealed that age and SVL were highly correlated in males (r = 0.49) and females (r = 0.75). The growth coefficient (K) was found to be 0.28 ± 0.18 in females and 0.62 ± 0.25 in males. The survival rate was 57.14% in females and 75.38% in males. The adult life expectancy was calculated at 2.83 years and 4.56 years in females and males, respectively. To sum up, males were larger than females, indicating male-biased sexual size dimorphism (SDI: -0.144). In addition, males had a greater mean age and longevity (max male age: 8 yr; max female age: 5 yr).

Unlabelled: Evolution of cooperation is a major, extensively studied problem in evolutionary biology. Cooperation is beneficial for a population as a whole but costly for the bearers of social traits such that cheaters enjoy a selective advantage over cooperators. Here we focus on coevolution of cooperators and cheaters in a multi-level selection framework, by modeling competition among groups composed of cooperators and cheaters.

Ecologically important in their native ecosystems, these typically cryptic plants remain understudied and fundamental knowledge of the biology, ecology, and evolution of most species is lacking. This gap limits our understanding of ecosystems and conservation management.

Coral reefs worldwide are threatened by increasing ocean temperatures because of the sensitivity of the coral-algal symbiosis to thermal stress. Reef-building corals form symbiotic relationships with dinoflagellates (family Symbiodiniaceae), including those species which acquire their initial symbiont complement predominately from their parents. Changes in the composition of symbiont communities, through the mechanisms of symbiont shuffling or switching, can modulate the host's thermal limits.

Pangolins are the most heavily trafficked mammals in the world, largely because of the high demand for their keratinous scales from the traditional Chinese medicine market. While seizures of pangolin material are largely composed of isolated scales, efficient approaches to reach species-level identification are missing. This mostly originates from the lack of comparative studies on the shape of pangolin scales, resulting in knowledge gaps on the imbricated effects of serial, ontogenetic, and evolutionary variations.

The expansion of urban settlements over native environments may expose biodiversity to a host of emerging contaminants, with unintended ecological effects. This study evaluated patterns of contamination of streamwater by antidepressants in the Upper Tietê River Basin, a watershed of high social, economic and environmental relevance for comprising both the largest urban settlement in South America (the Metropolitan Region of São Paulo) and remnants of a globally important biodiversity hotspot (the Atlantic Rainforest). We sampled 53 third-order streams draining catchments regularly distributed across a gradient in urban cover.
