Songbirds' reproductive success reduced by natural gas compressor noise
Some songbirds are not dissuaded by constant, loud noise emitted by natural gas pipeline compressors and will establish nests nearby. The number of eggs they lay is unaffected by the din, but their reproductive success ultimately is diminished. (2021-02-18)

One in 10 Ohio women thought abortion illegal amid attempts to ban at 6 weeks
Though Ohio never formally enacted a so-called ''heartbeat bill'' banning abortions after six weeks of gestation, legislative and legal actions appear to have fueled beliefs that abortion is illegal in the state, a new study has found. (2021-02-17)

Why overfishing leads to smaller cod
Overfishing, hunting and intensive agriculture and forestry can sometimes contribute to plants and animals becoming endangered. New research from Lund University in Sweden and University of Toronto can now show why this leads to entire populations becoming smaller in size, as well as reproducing earlier.

Biologists at the University of Bristol argue that some animals might be able to blackmail reluctant relatives into assisting with the rearing of young. The study is published today [2 February] in The American Naturalist. (2021-02-02)

Size matters: How the size of a male's weapons affects its anti-predator tactics
When males have to fight for reproductive rights, having larger weapons such as horns gives them an edge. However, this can also limit their mobility, making them more vulnerable to predators. In a recent study, scientists from Japan proved, for the first time, that males of a species adopt different anti-predator tactics--tonic immobility or escape--based on the size of their weapons, opening doors to a better understanding of the evolution of animal behaviors. (2021-01-28)

Loggerhead sea turtles lay eggs in multiple locations to improve reproductive success
Although loggerhead sea turtles return to the same beach where they hatched to lay their eggs, a new study finds individual females lay numerous clutches of eggs in locations miles apart from each other to increase the chance that some of their offspring will survive. (2021-01-28)

3D printing resins in dental devices may be toxic to reproductive health
Two commercially available 3D-printable resins, which are marketed as being biocompatible for use in dental applications, readily leach compounds into their surroundings.

With a little help from their friends, older birds breed successfully
The offspring of older animals often have a lower chance of survival because the parents are unable to take care of their young as well as they should. The Seychelles warbler is a cooperatively breeding bird species, meaning that parents often receive help when raising their offspring. A study led by biologists from the University of Groningen shows that the offspring of older females have better prospects when they are surrounded by helpers. (2021-01-19)

High-ranking male hyenas have better chances with females because they are less "stressed"
Scientists from the Leibniz-IZW have found that interacting with other males is more ''stressful'' for low-ranking than for high-ranking male spotted hyenas. This restricts the time and energy low-ranking males can invest in courting females and is therefore a key factor for lower reproductive success than their high-ranking rivals. This mechanism seems to be more important in determining the number and quality of offspring than physical traits such as attractiveness and fighting ability. (2021-01-18)

Genital shape key to male flies' sexual success
