ANÁLISIS ESPACIAL DE VARIANZA COMO ALTERNATIVA DE EVALUACIÓN DE ENSAYOS DE PROGENIES FORESTALES

open access: yesAgronomía Costarricense, 2016
El uso del diseño en bloques y la aleatori - zación de las diferentes progenies en cada uno de los bloques puede ser insuficiente para el control local de la variación dentro del área del ensayo.

FUENTES DE VARIANZA E INDICES DE VARIANZA EXPLICADA EN LAS CIENCIAS DEL MOVIMIENTO HUMANO

open access: yesPensar en Movimiento, 2002
El análisis de varianza (ANOVA) ha sido utilizado ampliamente para analizar datos de diseños experimentales en las ciencias del movimiento humano. En este trabajo se presentan y se discuten tres índices de varianza explicada: epsilon cuadrado, eta ...

Describing posterior distributions of variance components: Problems and the use of null distributions to aid interpretation

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 10, Page 2557-2574, October 2023., 2023
Abstract Assessing the biological relevance of variance components estimated using Markov chain Monte Carlo (MCMC)‐based mixed‐effects models is not straightforward. Variance estimates are constrained to be greater than zero and their posterior distributions are often asymmetric.

Floristic diversity, composition and dominance across Amazonian forest types respond differently to latitude

open access: yesJournal of Biogeography, Volume 50, Issue 4, Page 685-698, April 2023., 2023
Abstract Aim The latitudinal biodiversity gradient is considered a first‐order biogeographical pattern for most taxonomic groups. Latitudinal variation in plant diversity is not always consistent, and this could be related to the particular characteristics of different forest types.

A systematic review of animal personality in conservation science

open access: yesConservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Although animal personality research may have applied uses, this suggestion has yet to be evaluated by assessing empirical studies examining animal personality and conservation. To address this knowledge gap, we performed a systematic review of the peer‐reviewed literature relating to conservation science and animal personality.

Integration of qualitative and quantitative methods for land‐use‐change modeling in a deforestation frontier

open access: yesConservation Biology, Volume 36, Issue 6, December 2022., 2022
Abstract Development and implementation of effective protected area management to reduce deforestation depend in part on identifying factors contributing to forest loss and areas at risk of conversion, but standard land‐use‐change modeling may not fully capture contextual factors that are not easily quantified.

Patterns of leaf trait variation underlie ecological differences among sympatric tree species of Damburneya in a tropical rainforest

open access: yesAmerican Journal of Botany, Volume 109, Issue 9, Page 1394-1409, September 2022., 2022
Abstract Premise Although ecological differentiation driven by altitude and soil is hypothesized to promote coexistence of sympatric tree species of Damburneya (Lauraceae), the mechanistic role of leaf functional variation on ecological differentiation among co‐occurring species remains unexplored.
