Tell Me How Much DNA You Have and I'll Tell You What Your Sex Is: Sex Determination by Flow Cytometry of Spiderlings of Allocosa marindia

Ecology and Evolution, Volume 16, Issue 4, April 2026.
The manuscript addresses the sex determination of spiderlings of the wolf spider Allocosa marindia using flow cytometry. Spiders are born with a defined sex, but it is not possible to determine their sex phenotypically until the adult or near‐adult stage. Sex identification at early stages of development is of great interest for studies in evolutionary

Surveillance of ash trees under multiple threats: Integrating emerald ash borer and ash dieback dynamics with stakeholder behaviour

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
Tree‐health policies must balance identifying likely entry points and deployment of traps, targeted information campaigns and surveillance subsidies for land managers. Our unique, cross‐disciplinary approach can be applied to other pest/pathogen systems to inform tree‐health plans and how to balance resources.

A multiscale seasonal examination of the risk of harm to seabirds from vessels based on co‐occurrence in Alaskan waters

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Alaska's seascape supports globally significant seabird populations, including vulnerable and threatened species, and hosts economically important commercial fisheries and marine transportation corridors. Seasonal patterns of seabird movements and vessel traffic create a complex landscape of risk, defined as high levels of co‐occurrence ...

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and

Identifying potentially suitable and accessible refugia to mitigate impacts of an emerging disease on a rare tree

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...

Bright spots for advancing ecological understanding and conservation decision‐making

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract A lot can be learned by studying bright spots—defined as unexpected positive outcomes. In fields like public health, education, and oncology, identifying factors behind bright spots reveals previously unknown drivers of success that can be replicated elsewhere.
