Connecting sea to market: Using network analysis to understand social–ecological dynamics in seafood value chains in Pisco, Southern Peru

open access: yesPeople and Nature, Volume 7, Issue 10, Page 2465-2485, October 2025.
Abstract Small‐scale fisheries represent complex human‐nature interactions, targeting different species in different locations throughout the year. On land, fishers are at the core of diverse seafood value chains that serve local and distant markets.

Foliar spectral signatures reveal adaptive divergence in live oaks (Quercus section Virentes) across species and environmental niches

open access: yesNew Phytologist, Volume 248, Issue 1, Page 370-388, October 2025.
Summary Genomic tools have advanced our understanding of species and population structure, but distinguishing neutral from adaptive evolution remains challenging due to limited methods for measuring a broad spectrum of phenotypic traits. We used spectroscopic data from preserved leaves to test for adaptive divergence among populations of live oaks ...

Understanding the Impact of Institutions on Climate‐Adaptive Policy Designs: A Study of Collective Action Inference in Urban Water Systems

open access: yesPolicy Studies Journal, Volume 53, Issue 3, Page 637-653, August 2025.
ABSTRACT Feedback is ubiquitous in complex systems and critical to the process of designing public policies to solve problems such as climate adaptation. However, well‐known cognitive and institutional constraints can impact information feedback processes, limiting a system's ability to incorporate feedback into policy designs.

Rapid Ocean Warming Drives Sexually Divergent Habitat Use in a Threatened Predatory Marine Ectotherm

open access: yesGlobal Change Biology, Volume 31, Issue 7, July 2025.
How ectothermic, mobile marine predators are responding to climate change is uncertain due to lack of species‐specific data, which can mask the true impact of this threat. We investigate the impact of environmental conditions and thermal extremes on the behavior and distribution of angelsharks, a highly threatened elasmobranch of global conservation ...

Mutational load and adaptive variation are shaped by climate and species range dynamics in Vitis arizonica

open access: yesNew Phytologist, Volume 247, Issue 2, Page 998-1014, July 2025.
Summary Genetic load can reduce fitness and hinder adaptation. While its genetic underpinnings are well established, the influence of environmental variation on genetic load is less well characterized, as is the relationship between genetic load and putatively adaptive genetic variation.
