Human impacts on functional and taxonomic homogenization of plateau fish assemblages in Yunnan, China

open access: yesGlobal Ecology and Conservation, 2015
Human activities and the consequent extinctions of native species and invasions of non-native species have been changing the composition of species assemblages worldwide. These anthropogenic impacts alter not only the richness of assemblages but also the

A Theory-Informed Emotion Regulation Variability Index: Bray-Curtis Dissimilarity [PDF]

open access: yes
We propose Bray-Curtis dissimilarity as a theory-informed ER variability index. We demonstrate its sensitivity in detecting ER variability with simulation studies.

Morpho-genetic profiling and phylogenetic relationship of guava (Psidium guajava l.) as genetic resources in Pakistan

open access: yesRevista Brasileira de Fruticultura, 2018
Guava (Psidium guajava L.) is an open-pollinated crop having 25-40% dissimilarity index which promotes heterozygosity and adds new cultivars. Morpho-genetic characterization of 37 guava accessions was carried out for genetic variability and structure of ...

Confirmation of top cross hybrids in guava using morpho-molecular markers

open access: yesActa Agriculturae Slovenica
The study was conducted to confirm the genetic diversity and hybridity of seventeen guava progenies developed from the top crossing between genetically distinct green and purple guava. The morphological markers and biochemical and molecular markers were

Molecular approach in elite parents of papaya with a focus on seed physiological quality [PDF]

open access: yesRevista Brasileira de Fruticultura
: Papaya seeds have natural barriers (phenolic compounds, seed structure and genetic factors) that make their germination difficult. And the use of seeds is the main means of propagating the species, whether for commercial cultivation, maintenance of ...

Effects of neighborhood interaction on tree growth in a temperate forest following selection harvesting

open access: yesEcological Indicators, 2022
Selection harvesting is a common silvicultural practice in uneven-aged natural forests. Understanding the complex response of individual trees to forest harvesting is of great importance to clearly assess how forest ecosystems respond to future ...
