New research sheds light on origins of social behaviors
//www.koonmotors.com/releases/2023/09/230905155650.htm
Male fruit flies don't usually like each other. Socially, they reject their fellow males and zero in on the females they discern via chemical receptors -- or so scientists thought.

Male crested macaques more likely to respond to offspring screams recruiting support
//www.koonmotors.com/releases/2023/08/230829130028.htm
When infants are involved in agonistic conflicts, male crested macaques (Macaca nigra) are more likely to respond to screams from their own offspring. This is the conclusion of a recent study led by behavioral ecologists. The researchers studied the behavior of crested macaques in the Tangkoko Nature Reserve on Sulawesi, Indonesia, over a 24-month period (2008 to 2010).

Scientists solve mystery of why thousands of octopus migrate to deep-sea thermal springs
//www.koonmotors.com/releases/2023/08/230823165417.htm
Researchers used advanced technology to study a massive aggregation of deep-sea octopus gathered at thermal springs near an extinct underwater volcano off the coast of Central California. Warm water from hydrothermal springs accelerates development of octopus embryos, giving young octopus a better chance of survival. The Octopus Garden is the largest known aggregation of octopus on the planet -- the size of this nursery, and the abundance of other marine life that thrives in this rich community, highlight the need to understand and protect the hotspots of life on the deep seafloor from threats like climate change and seabed mining.

Biologists find what colors a butterfly's world
//www.koonmotors.com/releases/2023/08/230810141002.htm
As butterflies flit among flowers, they don't all view blossoms the same way. In a phenomenon called sexually dimorphic vision, females of some butterfly species perceive ultraviolet color while the males see light and dark. Biologists have discovered that in at least one species, the variation results from a vision gene's jump onto a sex chromosome. It's the first known finding that this kind of genetic change causes sexually dimorphic vision.

Protected sex: Grouper mating calls in marine managed areas
//www.koonmotors.com/releases/2023/08/230809130630.htm
Groupers produce distinct sounds associated with courtship, territoriality or reproduction. An autonomous mobile wave glider and passive acoustics were deployed to survey two marine protected areas on the western shelf of Puerto Rico to locate spawning aggregations of two commercially important species -- the Nassau and red hind groupers. Findings show these sites are critical habitat for both species and multiple previously unknown grouper species, which highlight the importance of expanding existing seasonal regulations.

一项新的研究北美鸣禽的发现birds can't keep up with the earlier arrival of spring caused by climate change. As a result, they're raising fewer young. By the end of the 21st century, climate change will cause springlike weather to begin 25 days earlier, but birds will only breed about seven days earlier. That change could lead to an average reduction of 12% in breeding productivity for songbird species.

A species of nemertean worm discovered by a marine biologist five years ago affects the reproductive performance of Caribbean spiny lobsters, a critical species in the Caribbean Sea and the Gulf of Mexico. Antonio Baeza, an associate professor in the Department of Biological Sciences, discovered the new worm while researching parental behaviors of the spiny lobster Panulirus argus in the Florida Keys. New research shows the worm affected embryo mortality, fecundity and reproductive output in brooding females.

Undergrad-driven project reveals drought's effects on painted turtles
//www.koonmotors.com/releases/2023/06/230628130412.htm
A projected rise in droughts could muddy the waters for painted turtles and some fellow freshwater-dwelling reptiles, says 11 years of data collected by 50-plus undergraduates. Two recent studies based on the data suggest that drought can lower the survival odds, slow the growth and even skew the ratio of female-to-male painted turtles inhabiting the ponds of the Cornhusker State. Those outcomes emerged despite the water level of a sampled pond in southwestern Nebraska remaining relatively steady throughout the observed periods of drought.

Do warmer temperatures make turtles better mothers?
//www.koonmotors.com/releases/2023/06/230623210244.htm
Warmer temperatures are known to make more turtle eggs become female hatchlings, but new research shows that those females also have a higher capacity for egg production, even before their sex is set. This finding may explain why many animals besides turtles have temperature-dependent sex determination and why the system persists, despite seeming like a risky strategy. It may also provide a troubling glimpse of what could lie ahead in a warming world.

How sweet it is: The fruit fly gut influences reproduction by 'tasting' fructose
//www.koonmotors.com/releases/2023/05/230525141353.htm
A research group has found that in fruit flies (Drosophila melanogaster), circulating fructose derived from dietary sugar is needed for enhanced egg production after mating. In this species, circulating fructose is required for an increase in germline stem cells, which divide into reproductive cells. This increase leads to enhanced post-mating egg production. These findings may help to determine whether fructose influences the reproduction of mammals, including humans.

Researchers successfully induce primate oocytes in the lab
//www.koonmotors.com/releases/2023/05/230525141343.htm
The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for researchers to control the differentiation of stem cells in the lab (in vitro). Of particular interest are oocytes, which are female germ cells that develop into eggs. Understanding their development could have far-ranging impacts, from infertility treatment to conservation of endangered species. A new study has successfully induced meiotic (dividing) oocytes from the embryonic stem cells of cynomolgus monkeys, which share many physiological traits with humans. By establishing a culture method for inducing the differentiation of meiotic oocytes, the researchers aimed to shed light on germ cell development in both humans and other primates.

Researchers have found that time-restricted fasting could cause fertility problems. Time-restricted fasting is an eating pattern where people limit their food consumption to certain hours of the day. It's a popular health and fitness trend and people are doing it to lose weight and improve their health. But the new study shows that time-restricted fasting affects reproduction differently in male and female zebrafish. Importantly, some of the negative effects on eggs and sperm quality can be seen after the fish returned to their normal levels of food consumption. The research team say that while the study was conducted in fish, their findings highlight the importance of considering not just the effect of fasting on weight and health, but also on fertility.

Scientists recently discovered that Luna moths use their long tails as decoys to throw bats off their trail. But their tails also make Luna moths might also make them stand out to potential mates and make them more conspicuous to lurking predators. A pair of complementary studies looked to see whether these colorful, bat-deflecting appendages might come with any additional costs or benefitt

近亲繁殖导致濒危ki的衰落ller whales
//www.koonmotors.com/releases/2023/03/230320143735.htm
The small size and isolation of the endangered population of Southern Resident killer whales in the Pacific Northwest have led to high levels of inbreeding. This inbreeding has contributed to their decline, which has continued as surrounding killer whale populations expand, according to new research.

Air pollution impairs successful mating of flies
//www.koonmotors.com/releases/2023/03/230314155054.htm
A research team demonstrates that increased levels of ozone resulting from anthropogenic air pollution can degrade insect sex pheromones, which are crucial mating signals, and thus prevent successful reproduction. The oxidizing effect of ozone causes the carbon-carbon double bonds found in the molecules of many insect pheromones to break down. Therefore, the specific chemical mating signal is rendered dysfunctional. The researchers show this effect in the vinegar fly Drosophila melanogaster and nine other species of the genus Drosophila. Most remarkably, the disrupted sexual communication also led to male flies exhibiting unusual mating behavior towards ozonated males of their own species.

New insights into cellular 'bridges' shed light on development, disease
//www.koonmotors.com/releases/2023/03/230309125021.htm
Most cells in the bodies of living things duplicate their contents and physically separate into new cells through the process of cell division. But across many species, germ cells, those that become eggs or sperm, don't fully separate. They remain interconnected through small bridges called ring canals and cluster together. In a new study, researchers uncover how it is that germ cells in fruit flies form these ring canals, a finding that they say will provide new insights into a widely shared feature of development and into diseases in which cell division is disrupted.
