Premise: There is a general lack of consensus on the best practices for filtering of single-nucleotide polymorphisms (SNPs) and whether it is better to use SNPs or include flanking regions (full "locus") in phylogenomic analyses and subsequent comparative methods.

Methods: Using genotyping-by-sequencing data from 22 species, we assessed the effects of SNP vs. locus usage and SNP retention stringency.

The Mojave and Sonoran Deserts, recognized as a global hotspot for bee biodiversity, are experiencing habitat degradation from urbanization, utility-scale solar energy (USSE) development, and climate change. In this study, we evaluated the current and future distribution of bee diversity, assessed how protected areas safeguard bee species richness, and predicted how global change may affect bees across the region. Using Joint Species Distribution Models (JSDMs) of 148 bee species, we project changes in species distributions, occurrence area, and richness under four global change scenarios between 1971 and 2050.

The introduction of non-native species across the world represents a major global challenge. Retracing invasion origin is an important first step in understanding the invasion process, often requiring detailed sampling within the native range. Insect species frequently host , a widespread endosymbiotic bacterium that manipulates host reproduction to increase infected female fitness.

Article Synopsis
  • Warming temperatures in spring and autumn are extending the breeding season for migratory birds in North America, but their success depends on their ability to adapt to changes in prey availability.
  • A study on black-throated blue warblers in New Hampshire used fecal DNA analysis to investigate their diets during the breeding season and found significant variations in diet composition related to seasonal prey availability.
  • The findings indicate that these warblers are flexible in their dietary choices and can adjust to seasonal changes, which may help them cope with climate-driven shifts in insect populations.

Developing bees derive significant benefits from the microbes present within their guts and fermenting pollen provisions. External microbial symbionts (exosymbionts) associated with larval diets may be particularly important for solitary bees that suffer reduced fitness when denied microbe-colonized pollen.To investigate whether this phenomenon is generalizable across foraging strategy, we examined the effects of exosymbiont presence/absence across two solitary bee species, a pollen specialist and generalist.
