Generalized graphical mixed models connect ecological theory with widely used statistical models

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Ecological dynamics are often analysed across multiple sites, times, and variables. Ecologists typically represent interactions across space, time, and variables using generalized linear mixed models (GLMMs), generalized additive models (GAM), and structural equation models (SEM).

Information flow and the adoption of soil‐improving and water conservation measures, and household welfare: Insights from a randomized controlled trial in Uganda

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Extension services are designed to facilitate the flow of information from researchers to farmers. However, information failures continue to impede the diffusion of soil‐improving and water conservation technologies in Sub‐Saharan African countries. We use a randomized controlled trial (RCT) to examine the impact of an extension‐based campaign

Traditional and Geometric Morphometrics and Invariant Shape Descriptors of Catfish Otoliths in the Yucatán Peninsula: Tools for Species Identification and Individual Size Estimation at Maya Archaeological Sites

open access: yesArchaeometry, EarlyView.
ABSTRACT This study investigates the use of otolith shape analysis for species identification and size estimation in Ariopsis felis and Bagre marinus, based on 181 modern otoliths obtained from a scientific collection and recent sampling in the coastal regions of Campeche and Yucatán, as well as 39 archaeological otoliths corresponding to the Early ...

Growth and Variation in Fallow Deer (Dama dama L.) From Two Contrasting Habitats in Southern Britain

open access: yesActa Zoologica, EarlyView.
ABSTRACT We have compiled a unique data set on the age, sex, body weight and dimensions of over 500 European fallow deer from two contrasting areas of habitat in southern England: a high‐density managed parkland population and a lower‐density feral woodland one.

Weaponry Investment in the Socially Monogamous Snapping Shrimp Alpheus brasileiro (Decapoda: Alpheidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Weapons are morphological structures used by animals in various contexts, especially in intra‐specific contests and visual displays. In snapping shrimps of the genus Alpheus, particularly the monogamous species Alpheus brasileiro, both sexes bear enlarged chelipeds, potentially conferring advantages in mate competition or territorial defence ...
