The costs and benefits of multiple mating in a mostly monandrous wasp [PDF]
, 2015 Funding: NERC DTGThe taxonomically widespread nature of polyandry remains a puzzle. Much of the empirical work regarding the costs and benefits of multiple mating to females has, for obvious reasons, relied on species that are already highly polyandrous.

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean
Remote Sensing in Ecology and Conservation, EarlyView.The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

A review on studies of behavioural ecology of Centrobolus (Diplopoda, Spirobolida, Pachybolidae) in southern Africa [PDF]
Arthropods, 2019 Forty-two studies on fire millipedes are reviewed in which mechanisms of selection; sperm competition and cryptic female choice were studied. Approaches to: (1) quantify size dimorphism and find the selection pressures operating on the sexes, (2 ...

SERS‐Based Nano‐ and Microsystems Toward Biomedical Applications
Small, EarlyView.This review provides a current overview of nano‐ and microscale SERS‐based devices, encompassing all aspects from material design to practical applications. We highlight controlled SERS‐active architectures, including patterned substrates, nanorods, microspheres, micromotors, and microneedles, as well as combinations of these microfluidic systems.

Global Fluoride Toxicology Landscape: Bibliometric Approaches and Scientific Mapping
Environmental Toxicology, EarlyView.ABSTRACT This study analyzed research trends in the 100 most‐cited articles on fluoride toxicology, a topic widely debated due to the toxic effects associated with levels deemed safe for human exposure. A bibliometric analysis was conducted using the Web of Science‐Core Collection, extracting data such as citation count, authors, keywords, journal ...

The adaptive function of masturbation in a promiscuous African ground squirrel.
PLoS ONE, 2010 Studies of animal mating systems increasingly emphasize female multiple mating and cryptic sexual selection, particularly sperm competition. Males under intense sperm competition may manipulate sperm quantity and quality through masturbation, which could

Evolution of sperm morphology in anurans : Insights into the roles of mating system and spawning location [PDF]
, 2014 Background: The degree of postcopulatory sexual selection, comprising variable degrees of sperm competition and cryptic female choice, is an important evolutionary force to influence sperm form and function.

Sperm competition in grey whales
Nature, 1988 SIR-Your legend for the drawing of grey whales taken from Cyall Watson's book Whales of the World, perpetuates the myth that a 'helper' male is necessary for successful mating in this species. The legend states that: "Only one male is involved in the actual mating; the other takes an upright position on the far side of the female, acting as a prop or ...

Environmental Toxicology, EarlyView.ABSTRACT Given the inevitability of human and animal exposure to acrylamide, there is increasing concern regarding its potential health risks. While a number of molecular mechanisms have been proposed, the complexity of acrylamide toxicological pathways and interactions remains incompletely characterized.
