Seasonal Difference of Gut Microbiota at a Stopover Site in Five Passerines of Different Migratory Behavior

open access: yesIntegrative Zoology, EarlyView.
Seasonal variation significantly reshaped gut microbiota composition in migratory passerine species, whereas the resident species Suthora webbiana showed no clear seasonal shift. Species with similar migratory behaviors exhibited consistent seasonal patterns in their core gut microbiota.

Demand Estimation with Text and Image Data

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT We propose a demand estimation approach that leverages unstructured data to infer substitution patterns. Using pre‐trained deep learning models, we extract embeddings from product images and textual descriptions and incorporate them into a mixed logit demand model.

A method to estimate actual infrastructure‐induced mortality by integrating hierarchical sources of imperfect detection

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Human infrastructures are among the most impactful wildlife threats. Although estimates of animal mortality by these structures exist over a given period, they typically do not account for several levels of imperfect detection (i.e. difference between recorded and true mortality).

VTMaxBox: A reproducible practical tool for measuring voluntary thermal maximum in terrestrial ectotherms

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Thermal traits are central to understanding how ectotherms respond to environmental warming. However, not all thermal traits describe the same biological process. Critical thermal maxima quantify physiological failure, whereas preferred temperatures describe thermal selection under choice conditions.
