A killer whale social network is vulnerable to targeted removals.
Individuals play various roles in maintaining social integrity of mammalian populations. However, many models developed for managing wildlife resources assume that all individuals are equal. Killer whales are social animals that rely on relationships within and among family groups for survival. In the northeastern Pacific, fish-eating, 'resident' killer whale populations are composed of matrili...
متن کاملVulnerability of a killer whale social network to disease outbreaks.
Emerging infectious diseases are among the main threats to conservation of biological diversity. A crucial task facing epidemiologists is to predict the vulnerability of populations of endangered animals to disease outbreaks. In this context, the network structure of social interactions within animal populations may affect disease spreading. However, endangered animal populations are often smal...
متن کاملArea of Origin, But Not Farm or Sex, Predicts Horse Carcass Weight as a Main Effect
The aim of this study was to evaluate the differences between cold carcass weights (CCW) for the Catalan Pyrenean horse (Cavall pirinenc català) breed according to different variables: area of origin, farm, gender and age. Linear regression models were applied using a generalized linear model (GLM) procedure for CCW of 397 animals (217 males and 180 females) slaughtered in a commercial abattoir...
متن کاملOrcinus orca – Killer Whale
Taxonomic notes: Orcinus orca is currently considered a single, cosmopolitan species, however many populations (including some which occur sympatrically) are ecologically, genetically and morphologically distinct (Rice 1998; Ford 2009). Despite such distinction, the global genetic diversity of the species appears low at both mitochondrial and nuclear DNA markers (Hoelzel et al. 2002; Morin et a...
متن کاملSex Work, Injection Drug Use, and Abscesses: Associations in Women, But Not Men
BACKGROUND Abscesses commonly occur among people who inject drugs (PWID). However, whether the risks are comparable between males and females, and the impact of sex work on abscess risk is unclear. The goal of this study was to examine the contemporary associations of gender and sex work with the risk of abscesses in PWID. METHODS Combining data from two cross-sectional studies conducted in t...
