Conservation Biology, EarlyView.Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

MODELO DE PREDICCIÓN DE LA DIGESTIBILIDAD DE PASTURAS HERB�CEAS NATURALES EN LAS ISLAS CANARIAS
Tropical and Subtropical Agroecosystems, 2009 Knowing the energy content of pastures is necessary in order to estimate the livestock carrying capacity of grasslands. Taking into account the high cost of analyses for determining the digestibility of herbaceous biomass as an estimate of its energy content, this study proposes a model for predicting digestibility values on the basis of the most ...

Entomologia Experimentalis et Applicata, EarlyView.We measured the plasticity in sexual bimaturism (SBM; differences between sexes in the timing of sexual maturity) in the black soldier fly (BSF) by exposing larvae to nutrient availability and humidity stress. Our results show that SBM can range between protandry and protogyny depending on the environmental quality. Additionally, we found the degree of

Quantitative Structure-Property Relationships for Predicting the Retention Indices of Fragrances on Stationary Phases of Different Polarity [PDF]
, 2017 El objetivo de este trabajo fue el desarrollo de relaciones cuantitativas estructura–propiedad predictivas para el modelado de índices de retención (I) de fragancias, medidas en tres fases estacionarias de diferente polaridad: DB–225MS, HP5–MS y HP–1. Se

Contrasting mechanisms driving the northward expansion of African raptors in Europe
Journal of Zoology, EarlyView.Recent climate warming and landscape changes are enabling African raptors to reach Europe through contrasting mechanisms. Using species distribution models, we show that the Atlas Long‐legged Buzzard expands northward following climatic suitability, whereas African vultures reach Europe despite low climatic favourability through socially mediated ...
