Correlaciones fenotípicas, genéticas y ambientales en Cucurbita moschata Duch. Ex Poir [PDF]

open access: yesActa Agronómica, 2005
El estudio estimó las correlaciones fenotípicas, genéticas y ambientales entre doce caracteres agronómicos en dos dialélicos de zapallo (uno entre cinco variedades y otro entre cinco líneas S1, originadas de las anteriores).

Estimación de heredabilidad y correlaciones genéticas en caracteres morfológicos y fisiológicos para una población de Zamia obliqua A.Br. (Zamiaceae: Cycadales)

open access: yesActualidades Biológicas, 2014
La respuesta a la selección natural en caracteres cuantitativos en una población natural depende de la magnitud de variabilidad genética y las correlaciones genéticas en los rasgos, y estos parámetros genéticos pueden diferir entre categorías de rasgos ...

Genetic diversity and IUCN Red List status

open access: yesConservation Biology, Volume 37, Issue 4, August 2023., 2023
Abstract The International Union for Conservation of Nature (IUCN) Red List is an important and widely used tool for conservation assessment. The IUCN uses information about a species’ range, population size, habitat quality and fragmentation levels, and trends in abundance to assess extinction risk.

Validating graph‐based connectivity models with independent presence–absence and genetic data sets

open access: yesConservation Biology, Volume 37, Issue 3, June 2023., 2023
Abstract Habitat connectivity is a key objective of current conservation policies and is commonly modeled by landscape graphs (i.e., sets of habitat patches [nodes] connected by potential dispersal paths [links]). These graphs are often built based on expert opinion or species distribution models (SDMs) and therefore lack empirical validation from data

Estimation of additive genetic variance when there are gene–environment correlations: Pitfalls, solutions and unexplored questions

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 5, Page 1245-1258, May 2023., 2023
Abstract Estimating the genetic variation underpinning a trait is crucial to understanding and predicting its evolution. A key statistical tool to estimate this variation is the animal model. Typically, the environment is modelled as an external variable independent of the organism, affecting the focal phenotypic trait via phenotypic plasticity.

Disentangling direct from indirect effects of habitat disturbance on multiple components of biodiversity

open access: yesJournal of Animal Ecology, Volume 91, Issue 11, Page 2220-2234, November 2022., 2022
Given that anthropogenic disturbance is one of the most important factors influencing ecological communities, a better understanding of the reciprocity of the various components of biodiversity is needed to predict the development of disturbed natural communities.
