Study on Life History Strategies of Anurans in Tropical Rainforest: Lifespan and Age at Sexual Maturity. [PDF]

Ecol Evol
This study presents the first comprehensive analysis of lifespan and age at sexual maturity in seven common anuran species from Hainan Island's tropical rainforest, filling a critical gap in tropical amphibian ecology. The results reveal significant interspecific variation in lifespan (5 ~ 9 years) and maturity age (3 ~ 5 years), indicating a “slow ...

How Do Females Persist? Life History, Environment, and Female Advantage in Gynodioecious <i>Cirsium</i>. [PDF]

Ecol Evol
We quantified how life history, reproductive traits, and environment shape female frequencies in two gynodioecious thistles, the polycarpic Cirsium heterophyllum and the monocarpic C. palustre, which differed strongly in female advantage. In both species, reproductive traits were the main drivers of female advantage, but their relative importance ...

The Potential Habitat of <i>Liparis campylostalix</i> (Orchidaceae) in China Under Climate Change Scenario Predicted by MaxEnt Model. [PDF]

Ecol Evol
This study used the Maxent model, ENMTools, and ArcGIS to predict L. campylostalix's ecological pattern in China, based on its geographical distribution and environmental factors. Under current climate, it mainly distributes in Liaoning, Jilin, Shandong (suitable area 1.845 million km2), with four key variables affecting it: annual precipitation (27.9%)

Complete Mitochondrial Genome Sequencing of Asian Glass Lizards (Anguidae: <i>Dopasia</i>): Comparative Analysis With Limbless Anguids and New Insights Into the Adaptive Evolution of Protein-Coding Genes. [PDF]

Ecol Evol
This study analyzed mitochondrial genomes from eight individuals of two Dopasia species and 28 other Anguidae sequences to investigate selection patterns in protein‐coding genes. Positive selection was detected in six of the 13 mitochondrial genes, with amino acid preferences correlating with geographic distribution, suggesting a role in environmental ...

Stagonosporopsis cucurbitacearum Effector Protein ScAA9 Contributes to Virulence and Triggers Plant Immune Responses. [PDF]

Mol Plant Pathol
The AA9 family protein ScAA9 of Stagonosporopsis cucurbitacearum plays dual roles as both a virulence factor for infection and a PAMP for host immune manipulation, highlighting the complexity of S. cucurbitacearum–host interactions. ABSTRACT Fungal pathogens secrete cell wall‐degrading enzymes that either act as virulence factors or are perceived by ...

Sex Determination in Sponges. [PDF]

Mol Reprod Dev
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

Comparative transcriptome analysis revealed genes involved in the sexual size dimorphisms and expressed sequence tag-Simple Sequence Repeat loci validation in Odorrana graminea

Frontiers in Ecology and Evolution, 2023
Sexual size dimorphism (SSD) is widespread among animals and is characterized by differences in body size between sexes. Previous studies suggested SSD might reflect the adaptations of particular sexes to their specific reproductive or ecological roles ...
