Limited inbreeding avoidance at the gamete level despite inbreeding depression in Atlantic salmon (Salmo salar). [PDF]
Our study investigates inbreeding avoidance mechanisms at the gamete level in domesticated Atlantic salmon using sperm motility traits assessments, fertilisation trials, and paternity analysis under competitive conditions. We demonstrate that ovarian fluid from sibling females reduces sperm motility traits and fertilisation rates but found no ...

Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

The McKinleys of Punch: Politics and the Press in Melbourne, 1870s to 1920s
This article re‐examines the Melbourne Punch (1855–1925; known simply as Punch from 1900) as a political weapon in the cut‐and‐thrust of Victorian, local, and national politics, in the hands of its longest‐serving, but least‐known proprietor, Alexander McKinley (1848–1927).

ABSTRACT Parents of children who were removed from home are generally under‐researched, and there is a shortage of knowledge concerning their perceptions and experiences, particularly in complex contexts. Using a context‐informed perspective and intersectionality theory, this study aims to better understand the experiences of parents regarding their ...

Abstract Most business students are not interested in becoming lawyers. Therefore, business law and legal environment instructors must convey why students should study business law. To assist instructors (especially first‐time ones), this teaching note presents interrelated pedagogical questions to introduce the first week of class.

Thirty Years of the Biology of Spermatozoa: The Rise and Future of an Evolutionary Paradigm
A sperm bundle taken from the seminal vescicles of the dung beetle, Onthophagus taurus. Image credit: Leigh W. Simmons. ABSTRACT In the early 1970s, Geoff Parker recognised that because females frequently mate with multiple males, competition for fertilizations will impose significant sexual selection on males and their ejaculates.

We exposed male house mice (fathers) to high‐male or high‐female density conditions during their sexual development and quantified the sperm sex ratio of their sons. Our analyses revealed that the sons of fathers reared under high‐male density conditions, produced, on average, higher numbers of daughter‐producing sperm compared to sons of fathers ...

Sexual conflict as a constraint on asexual reproduction: an empirical review
ABSTRACT Theory predicts that facultatively asexual animals, which can leverage the advantages of both sexual and asexual reproduction, should outcompete obligately sexual and obligately asexual animals. Yet, paradoxically, obligate sexual reproduction predominates in many animal lineages, while the most flexible form of facultative asexuality (i.e ...

Local Government Proliferation and Fiscal Efficiency: Evidence From Ghana
ABSTRACT In many active decentralized nations in the developing world, the number of sub‐national administrative units has continued to increase over the past few decades. In most cases, this churning of more decentralized units does not go without contestation, with critics arguing that they are not done in the true spirit of decentralization but ...

This study combined smartphone‐based ecological momentary assessment (EMA) and fixel‐based analysis (FBA) of diffusion MRI data to examine intraindividual variability (IIV) in cognitive performance and its neural correlates in chronic mild TBI. Our findings revealed persistent cognitive instability linked to daily symptom fluctuations and structural ...
