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

Journal 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.

Can morphological traits explain species-specific differences in meta-analyses?: a case study of forest beetles [PDF]

, 2023
Meta-analyses have become a valuable tool with which to synthesise effects across studies, but in ecology and evolution, they are often characterised by high heterogeneity, where effect sizes vary between studies.

A comprehensive dataset of morphological traits for Indian climbers. [PDF]

Data Brief
Climbers are among the most conspicuous elements of tropical forest ecosystems, where they exhibit exceptional taxonomic diversity. Despite their ecological significance, climbers are notably underrepresented in global plant functional trait databases, limiting our understanding of their ecological strategies and adaptive responses to environmental ...

Evolution of morphological traits in Verbenaceae [PDF]

American Journal of Botany, 2012
• Premise of the study: A new infrafamilial circumscription of the Verbenaceae with eight tribes: Casselieae, Citharexyleae, Duranteae, Lantaneae, Neospartoneae, Petreeae, Priveae, and Verbeneae, has been recently proposed, on the basis of molecular phylogenetic studies. Two genera, Dipyrena and Rhaphithamnus, remain unplaced.

An Intrinsic Geometric Constraint on Morphological Stomatal Traits [PDF]

Frontiers in Plant Science, 2021
A strong negative non-linear relationship exists between stomatal density (SD) and size (SS) or length (SL), which is of high importance in gas exchange and plant evolution. However, the cause of this relationship has not been clarified. In geometry, SD has an intrinsic relationship with SS−1 or SL−2, which is defined as a geometric constraint here. We

Heritability of Morphological and Behavioural Traits in Evolving Robots

SSRN Electronic Journal, 2022
AbstractIn the field of evolutionary robotics, choosing the correct genetic representation is a complicated and delicate matter, especially when robots evolve behaviour and morphology at the same time. One principal problem is the lack of methods or tools to investigate and compare representations.

Physical ecosystem engineering by emergent aquatic vegetation: the importance of biomechanical traits [PDF]

, 2011
PhDThis thesis explores the potential of the emergent macrophyte Sparganium erectum to act as a physical ecosystem engineer and delivers an understanding of the vegetative processes that enable it to function in such a capacity.

Piecemeal microautophagy of the nucleus: Genetic and morphological traits [PDF]

Autophagy, 2009
Nucleus-vacuole (NV) junctions are formed in Saccharomyces cerevisiae through interactions between Vac8 in the vacuole membrane and Nvj1 in the perinuclear ER. Upon starvation, vesicles containing part of the nucleus emanate from these contact sites and finally pinch off into invaginations of the vacuole.

Phenotypic evolution and hidden speciation in Candidula unifasciata ssp. (Helicellinae, Gastropoda) inferred by 16S variation and quantitative shell traits [PDF]

, 2006
In an effort to link quantitative morphometric information with molecular data on the population level, we have analysed 19 populations of the conchologically variable land snail Candidula unifasciata from across the species range for variation in ...
