How Food Geometry and Toughness Influence Ingestive Patterns in Lemurs

American Journal of Primatology, Volume 88, Issue 7, July 2026.
Initial bite placement is influenced by food toughness and geometry. Species‐specific feeding strategies reflect differences in masticatory morphology and functional flexibility. Lemur catta is more likely to use the postcanine tooth row; Propithecus verreauxi prefers anterior biting. ABSTRACT We investigate the extent to which food toughness, geometry,

Evaluación de criterios de bondad de ajuste para modelos logit marginales

SaberEs, 2009
En este trabajo se estudia el comportamiento de medidas de bondad de ajuste de modelos logit marginales para datos binarios correlacionados. Algunas de ellas son de carácter descriptivo, basadas generalmente en la noción de pérdida incurrida al usar un modelo aproximado para describir la realidad, y otras constituyen estadísticas globales de bondad de ...

High and dry: Environmental conditions drive opportunities for disease transmission in desert bighorn sheep

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
By using probabilistic models to predict contacts as a function of spatially and temporally varying environmental conditions, we show that population‐level conditions at the time of disease introduction can structure opportunities for transmission within each population.

Environmental detection of the amphibian chytrid fungus in water bodies is associated with host infection along a deforestation gradient

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Linking environmental pathogen detection with host infection patterns can improve surveillance of diseases involving environmental transmission, particularly where direct host sampling is logistically challenging. This approach enables the identification of areas of elevated transmission risk and supports targeted monitoring and management under ...

A sensory ecology approach to understanding snakebites: Influence of sensory cues on the strike of the lancehead pitviper

Journal of Zoology, Volume 329, Issue 3, Page 237-246, July 2026.
Snakes are notable for having a broad range of predators and one of the most diverse repertoires of defensive behaviors. During heightened responses to aversive stimuli, one of the behaviors displayed is the venomous bite, particularly relevant because it triggers snakebite incidents in humans.

Specification(s) of Nested Logit Models [PDF]

The nested logit model has become an important tool for the empirical analysis of discrete outcomes. There is some confusion about its specification of the outcome probabilities. Two major variants show up in the literature.

Estimating nonparametric mixed logit models via EM algorithm [PDF]

The aim of this paper is to describe a Stata routine for the nonparametric estimation of mixed logit models using a Expectation-Maximisation algorithm. We also compare the performance of our estimator with respect to more typical parametric mixed logit ...
