Ancient hybridization and phylogenetic discordance: Exploring evolutionary complexity in Asteraceae

Applications in Plant Sciences, Volume 14, Issue 3, May-June 2026.
Abstract Premise Conflicting phylogenetic signals are common in plant phylogenomics and often reflect evolutionary histories shaped by processes like hybridization, incomplete lineage sorting, and whole‐genome duplication (WGD). We aimed to identify and assess these complex processes in the hyper‐diverse family Asteraceae to offer insight into the ...

Charge towards green finance ignores risks of nature commodification: Evidence from the UK's climate and nature recovery policy landscape

People and Nature, Volume 8, Issue 5, Page 1297-1308, May 2026.
Abstract The urgent need for up‐scaled finance has become central to the climate and nature recovery discourses worldwide. With most existing investments coming from public sources, closing the financing gap has become the overpowering argument for calling for private investments into nature restoration and conservation.

Sugar provisioning increases parasitoid numbers in agroecosystems but may not reduce pest densities: A meta‐analysis

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

fastbioclim: An R package for creating custom‐time bioclimatic and derived environmental summary variables

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1585-1594, May 2026.
Abstract Bioclimatic variables, widely used in ecological and biogeographical studies, are typically derived from 30‐year averages of monthly data (e.g. 1971–2000). Unfortunately, the use of these long‐term averaged variables often creates a temporal mismatch with the observational data collected, which potentially undermines how environmental ...

A Natural Language Processing Approach to Identifying Partisan Framing of Climate Change Denialism, Fatalism, and Solutions in US Congressional Speeches

Policy Studies Journal, Volume 54, Issue 2, May 2026.
ABSTRACT This study examines the evolution of climate change discourse in the United States Congress from 1987 to 2017, employing natural language processing (NLP) techniques to analyze floor speeches. Using a la carte (ALC) word embeddings, we investigate how Democratic and Republican members of Congress frame climate change, focusing on denialist ...
