DNA barcoding uncovers two putative new species in Trachelyopterus (Siluriformes: Auchenipteridae)

Journal of Fish Biology, EarlyView.
Abstract Trachelyopterus is a cryptic genus within the Neotropical catfish family Auchenipteridae with a complex history of taxonomic revisions. Despite the notable morphological and genetic similarities among its species, some studies suggest that the genus harbours greater diversity than is currently recognized, including additional species yet to be

Inbreeding and its effect on fitness traits in captive populations of North Persian leopard and Mhorr gazelle [PDF]

, 2015
In this study, linear mixed model analyses was conducted to assess inbreeding depression, purging and founder heterogeneity in relation to fitness traits (survival traits and litter size) in captive populations of North Persian leopard and Mhorr gazelle.

Lifespan of companion dogs seen in three independent primary care veterinary clinics in the United States

Canine Medicine and Genetics, 2020
Background The privately owned companion dog is an emerging model in comparative medicine, notably because it shares the human environment including its risk factors, is affected by many analogous age-related diseases, receives comparable medical care ...

Dissecting the genetic basis of climatic adaptation in wild relatives (Malus baccata) for climate‐resilient apple breeding

Journal of Integrative Plant Biology, EarlyView.
This comprehensive map of genetic variation in wild apple (Malus baccata) and set of key genes associated with adaptation to temperature, precipitation, and soil properties establishes a foundation for breeding climate‐resilient apple cultivars and conserving the genetic resources of wild crop relatives.

Genetic diversity of the Brazilian Creole cattle Pé-duro assessed by microsatellites and mitochondrial DNA

Revista Brasileira de Zootecnia, 2012
The objective of this study was to describe the genetic diversity and structure of the largest Pé-duro population by assessing variation at ten autosomal microsatellite (STR) loci and mitochondrial DNA (mtDNA) sequences.

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

New Phytologist, EarlyView.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Classical, Ancestral, and New Inbreeding of X-Chromosome in Czech Local Dairy Goat Breed

, 2023
The importance of the autosomal inbreeding coefficient for livestock production traits is well documented. In contrast, little is known about inbreeding coefficients for X-chromosomes in livestock populations. On the other hand, several studies have shown that genes on the X-chromosome can contribute to variation in the breeding values of traits ...

Spatial inference of ancestor locations suggests northern refugia for canopy‐forming kelps in the Pacific Northwest

New Phytologist, EarlyView.
Population genetic structure in the Pacific Northwest for (a–c) Nereocystis and (d–f) Macrocystis. Summary Pockets of the formerly glaciated Pacific coastline of North America likely remained ice‐free throughout the Last Glacial Maximum (LGM). These areas may have served as refugia for terrestrial species, but less is known about their role in the ...

The genetic architecture of leaf vein density and its importance for photosynthesis in maize

New Phytologist, EarlyView.
Vein types in maize leaves. Summary Leaf venation density has significantly increased during plant evolution. Higher densities are observed in angiosperms compared with early land plants, and among angiosperms, recently diverged C4 species have the highest values.
