A genomic test of subspecies in the Eunota togata species group (Coleoptera: Cicindelidae): Morphology masks evolutionary relationships and taxonomy

The paper uses genomic and mtDNA data to reassess the taxonomy of tiger beetle subspecies, finding that morphology masks true evolutionary relationships and revealing three distinct species within E. togata.

The arthropod associates of 155 North American cynipid oak galls

The paper reports rearing records of arthropods from over 527,000 oak galls, identifying 151,075 animals and providing ecological and phylogenetic insights into gall-associated taxa.

Speciation in Nearctic oak gall wasps is frequently correlated with changes in host plant, host organ, or both.

This study investigates host shifts in Nearctic oak gall wasps and finds frequent shifts between host plants and organs, suggesting host shifts drive speciation in this group.

The role of ecology and geography in the evolution of habitat isolation and sexual isolation among sister species of host-plant-specific insects

The paper examines how ecology and geography influence habitat and sexual isolation in closely related gall-forming wasp species, finding that sympatric species with different host plants show the strongest isolation.

Ormyrus labotus Walker (Hymenoptera: Ormyridae): another generalist that should not be a generalist is not a generalist

The study reveals that the parasitic wasp Ormyrus labotus, considered a generalist, is actually a complex of multiple specialized species, highlighting the limitations of morphological classification.

Global port survey quantifies commercial shippings effect on biodiversity

The paper quantifies how commercial shipping affects biodiversity by analyzing environmental DNA in ports across multiple regions, finding increased community similarity with more ship voyages and identifying non-indigenous species.

Is energetics or competition a stronger driver of male smallmouth bass seasonal reproductive timing?

The paper investigates whether energetics or competition drives reproductive timing in male smallmouth bass, finding that energetic constraints have a stronger influence.

The genomics of trait combinations and their influence on adaptive divergence

The paper investigates how genetic correlations between traits influence adaptive divergence in apple maggot flies, showing that antagonistic pleiotropy shapes genomic footprints of rapid adaptation.

Invertebrate Community Associated with the Asexual Generation of Bassettia pallida Ashmead (Hymenoptera: Cynipidae)

The paper documents the invertebrate community associated with the asexual generation of Bassettia pallida and compares it to two other cynipid gall wasps.

Environmental DNA survey captures patterns of fish and invertebrate diversity across a tropical seascape

The paper uses eDNA surveys to assess fish and invertebrate diversity across a tropical Caribbean bay, finding significant community differences driven by habitat specialists and wave tolerance.

A keeper of many crypts: the parasitoid Euderus set manipulates the behavior of a taxonomically diverse array of oak gall wasp species

The paper investigates whether the parasitoid Euderus set manipulates behavior in multiple gall wasp species beyond its known host, finding it affects at least six taxonomically diverse species.
