External structures at the nest‐site predict asymmetric architecture of nests in a mud‐building bird

open access: yesIbis, EarlyView.
In the animal kingdom, nests are essential structures and textbook examples of extended phenotypes. However, the relationship between builders, nest traits and the nest‐site remains poorly understood. We indirectly examine whether structures in the nest‐site influence nest‐building behaviour, specifically focusing on their effect on nest architecture ...

A statistical model describing the sunshine in the southern metropolitan area of the Mexico Valley

open access: yesGeofísica Internacional, 1990
Se propone un modelo estadístico que simule la densidad de probabilidades para la duración de la radiación solar basado en la suposición de que los intervalos de luz solar y de penumbra se distribuyen exponencialmente.

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

open access: yesNew Phytologist, EarlyView.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Issue Attention in Public Opinion Polls: Pollsters as Agenda Responders and Agenda Setters

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Polling organizations, like other policy actors, must prioritize certain issues. We argue that, for normative and financial reasons, pollsters prioritize issues that are viewed as important by other institutions and the public, leading them to focus survey questions on issues that are on congressional and media agendas, and which are public ...

An Exact Method for Reliable Shortest Path Problems With Correlation

open access: yesNetworks, Volume 87, Issue 4, Page 372-389, June 2026.
ABSTRACT Shortest path problems often arise in contexts where travel times are uncertain. In these settings, reliable paths are often valued more than paths with lower expected travel times. This has led to several variants of reliable shortest path problems (RSPP) that handle travel time reliability differently. We propose an algorithmic framework for

Acclimatisation duration, not just release type, drives post‐release settlement in a large‐scale carnivore reintroduction programme

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our study highlights that when acclimatisation periods are too short, the substantial economic and logistical investment in soft‐release protocols may fail to deliver the expected conservation gains. Therefore, defining evidence‐based acclimatisation periods that are long enough to promote settlement, yet compatible with logistical constraints, may ...
