Phylogeny offers a powerful framework for understanding mechanisms driving community assembly. Yet, most empirical studies in community phylogenetics rely on observational approaches. In this study, we explore how two important drivers of community assembly—habitat size and predator presence—shape species richness and phylogenetic relatedness of prey communities by altering colonization and extinction processes. Using bromelia...

Using recently published chromosome‐length genome assemblies of two damselfly species, Ischnura elegans and Platycnemis pennipes , and two dragonfly species, Pantala flavescens and Tanypteryx hageni , we demonstrate that the autosomes of Odonata have undergone few fission, fusion, or inversion events, despite 250 million years of separation. In the four genomes discussed here, our results show that all autosomes have a clear o...

Sport-related brain injury is very common, and the potential long-term effects include a wide range of neurological and psychiatric symptoms, and potentially neurodegeneration. Around the globe, researchers are conducting neuroimaging studies on primarily homogenous samples of athletes. However, neuroimaging studies are expensive and time consuming, and thus current findings from studies of sport-related brain injury are often...

Ecological diversification of aquatic insects has long been suspected to have been driven by differences in freshwater habitats, which can be classified into flowing (lotic) waters and standing (lentic) waters. The contrasting characteristics of lotic and lentic freshwater systems imply different ecological constraints on their inhabitants. The ephemeral and discontinuous character of most lentic water bodies may encourage dis...

Aim To explore the phylogenetics and historical biogeography of the dragonfly family Petaluridae (known as ‘petaltails’), a relict dragonfly group with unique habitat and life history attributes. Location Australia, New Zealand, Japan, Chile and North America. Methods Using five mitochondrial and three nuclear gene fragments we recovered garli ‐ part maximum likelihood and Bayesian phylogenetic hypotheses for 10 of the 11 exta...
