Relationship of phenotypic variation and genetic admixture in the Saltmarsh–Nelson\u27s sparrow hybrid zone [PDF]

open access: yes, 2015
Hybridization is influential in shaping species\u27 dynamics and has many evolutionary and conservation implications. Identification of hybrid individuals typically relies on morphological data, but the assumption that hybrids express intermediate traits

Morphological and Geographical Traits of the British Odonata

open access: yesBiodiversity Data Journal, 2014
Trait data are fundamental for many aspects of ecological research, particularly for modeling species response to environmental change. We synthesised information from the literature (mainly field guides) and direct measurements from museum specimens, providing a comprehensive dataset of 26 attributes, covering the 43 resident species of Odonata in ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

open access: yesMolecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

TRY plant trait database - enhanced coverage and open access [PDF]

open access: yes, 2020
Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits ...

Morphological and population genomic evidence that human faces have evolved to signal individual identity. [PDF]

open access: yes, 2014
Facial recognition plays a key role in human interactions, and there has been great interest in understanding the evolution of human abilities for individual recognition and tracking social relationships.

Overview of molecular signatures of senescence and associated resources: pros and cons

open access: yesFEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Effects of Shell Morphology on the Weight Traits of Manila Clam (Ruditapes philippinarum) from Different Geographical Populations

open access: yesProgress in Fishery Sciences, 2023
Shell morphological traits are important quantitative traits in shellfish. Shell morphology is usually affected by many factors, such as the ecological environment and shellfish genetics.

Phylogenetic patterns of diversification across ecological niches in the African tree genus Guibourtia [PDF]

open access: yes, 2018
Adaptive evolution is thought to be a major driver of organism diversification but the link between phenotypic traits and environmental niche remains little documented in tropical trees.

Inbreeding, Microsatellite Heterozygosity, and Morphological Traits in Lipizzan Horses [PDF]

open access: yesJournal of Heredity, 2003
While the negative effects of inbreeding and reduced heterozygosity on fecundity and survival are well established, only a few investigations have been carried out concerning their influence on morphological traits. This topic is of particular interest for a small and closed population such as the Lipizzan horse.
