Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

PLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

Data from: Inbreeding, inbreeding depression and infidelity in a cooperatively-breeding bird [PDF]

, 2018
Inbreeding depression plays a major role in shaping mating systems: in particular, inbreeding avoidance is often proposed as a mechanism explaining extra-pair reproduction in socially-monogamous species.

Strong differentiation between source and ex situ populations of rare plant species revealed by next‐generation sequencing

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is being lost rapidly worldwide due to factors such as climate change and habitat loss. To help safeguard plant populations, conservation strategies include seed banks and conservation cultures. However, it remains unclear how cultivation affects genetic variation compared with wild populations.

A model to infer the demographic structure evolution of endangered donkey populations

Animal, 2017
Stemming from The Worldwide Donkey Breeds Project, an initiative aiming at connecting international researchers and entities working with the donkey species, molecularly tested pedigree analyses were carried out to study the genetic diversity, structure ...

Minimizing inbreeding by managing genetic contributions across generations [PDF]

, 2003
Here we present the strategy that achieves the lowest possible rate of inbreeding (DeltaF) for a population with unequal members of sires and dams with random mating. This new strategy results in a DeltaF as much as 10% lower than previously achieved.

Why rotation and mixture fail: treatment history and the declining acaricide efficacy in Varroa destructor

Pest Management Science, EarlyView.
The effect of IRM strategies (rotation, mixture), one additional year under acaricide treatment (Years treated (+1 year)), and one year without acaricide treatment (Years off treatment (+1 year) on mite mortality relative to an approximately 17% baseline.

Genomic analysis of the inbreeding load for body weight, carcass and reproductive traits in the Rubia Gallega beef cattle population

Genetics Selection Evolution
Background Inbreeding, resulting from mating between relatives, leads to inbreeding depression, which can be traced back to hidden ancestral inbreeding loads.

Genetics of consanguinity and inbreeding in health and disease

Annals of Human Biology, 2017
Context: Inbreeding increases the level of homozygotes for autosomal recessive disorders and is the major objective in clinical studies. The prevalence of consanguinity and the degree of inbreeding vary from one population to another depending on ...

Exome sequencing in schizophrenic patients with high levels of homozygosity identifies novel and extremely rare mutations in the GABA/glutamatergic pathways.

PLoS ONE, 2017
Inbreeding is a known risk factor for recessive Mendelian diseases and previous studies have suggested that it could also play a role in complex disorders, such as psychiatric diseases.

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.
