Personality disorders as predictors of intimate partner violence: A meta-analysis.

Clin Psychol Rev 2021 May 28;88:102047. Epub 2021 May 28.

Purdue University, United States of America.

Despite years of research demonstrating a relation between personality pathology and intimate partner violence (IPV), no meta-analysis has been published examining how well, or poorly, all ten personality disorders (PDs) predict IPV perpetration or victimization, nor has any meta-analysis examined these relations across types of IPV. Therefore, the present study was undertaken to synthesize existing research on the effects of all ten PDs, as well as psychopathy and global PD symptoms, on physical, psychological, and sexual IPV perpetration and victimization. An initial search in PsycINFO, PubMed, and Sociological Abstracts yielded 3988 results. Read More

Assessing the Viability of American Horseshoe Crab () Embryos in Salt Marsh and Sandy Beach Habitats.

Biol Bull 2021 Jun 26;240(3):145-156. Epub 2021 Apr 26.

AbstractFor animal embryos that develop externally, the physio-chemical environment can substantially affect offspring viability. In the case of the American horseshoe crab (), sediment conditions along estuarine shorelines influence development rates and embryonic viability. Sandy beach habitats are considered to have optimal conditions for horseshoe crab embryonic development; however, spawning is often observed outside of these optimal habitats, in areas such as salt marshes, where reduced oxygen availability is thought to decrease the viability of eggs laid in these sediments.

Rhizosphere Bacterial Networks, but Not Diversity, Are Impacted by Pea-Wheat Intercropping.

Front Microbiol 2021 28;12:674556. Epub 2021 May 28.

Agroécologie, AgroSup Dijon, INRAE, Université de Bourgogne - Université de Bourgogne Franche-Comté, Dijon, France.

Plant-plant associations, notably cereal-legume intercropping, have been proposed in agroecology to better value resources and thus reduce the use of chemical inputs in agriculture. Wheat-pea intercropping allows to decreasing the use of nitrogen fertilization through ecological processes such as niche complementarity and facilitation. Rhizosphere microbial communities may account for these processes, since they play a major role in biogeochemical cycles and impact plant nutrition. Read More

Genome-Wide Association Studies Reveal Susceptibility Loci for Noninfectious Claw Lesions in Holstein Dairy Cattle.

Front Genet 2021 28;12:657375. Epub 2021 May 28.

Animal Science Department, University of California, Davis, Davis, CA, United States.

Sole ulcers (SUs) and white line disease (WLD) are two common noninfectious claw lesions (NICL) that arise due to a compromised horn production and are frequent causes of lameness in dairy cattle, imposing welfare and profitability concerns. Low to moderate heritability estimates of SU and WLD susceptibility indicate that genetic selection could reduce their prevalence. To identify the susceptibility loci for SU, WLD, SU and/or WLD, and any type of noninfectious claw lesion, genome-wide association studies (GWAS) were performed using generalized linear mixed model (GLMM) regression, chunk-based association testing (CBAT), and a random forest (RF) approach.
