What happens if a fish gets its tail bitten off? It must survive the injury, but also decide what is more important: recovering or producing offspring. Read on to find out how a deep-sea fish copes with this dilemma. Anastasia YandulskayaI am a PhD candidate at Northeastern University in Boston. I study regeneration of the […]
With human puberty seemingly beginning earlier and earlier, have you ever wondered what triggered sexual development? Dodd et al., studied just that by examining development in clownfish. Brandy BiggarI am a 2nd year Master’s student at the Memorial University of Newfoundland. I am researching the highly invasive species the European green crab, and the impact […]
Same-sex sexual behavior exists across a wide range of animals, but the behavior has long puzzled scientists because of the apparent paradox of mating behavior that does not produce offspring. What is the adaptive value of same-sex mating and what are the different reasons it has evolved in so many species? A recent paper describes […]
Evolution is riddled with trade-offs. One of the classic examples is how to spread maternal resources – is it better for an individual to have a lot of babies or invest more into only one or two? Researchers examined how this trade-off plays out in the marine world by comparing the competing reproductive strategies of […]
Like plastic bags and other larger plastic pieces, these insidious micro particles can make their way into animal digestive tracts and pollute the places they live. This pollution is what concerns Doctors Beckwith and Fuentes, from Florida State University. If microplastics are spreading through the ocean, what does this mean for the future of sea […]
What makes a fish a good mom? Read here to see why scientists now think that big fish moms are the best fish moms. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the sensory biology of deep-sea fishes. I am now working with the South Carolina DNR at […]
As the Earth warms, sea ice declines. What happens to those animals who rely on the ice? Today’s oceanbites looks at one animal, the ringed seal, and how it may be affected by climate change! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I […]
Killer whales, or orcas (Orcinus orca), are amazingly intelligent and social animals. What can they tell us about the evolution of menopause? Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and […]
Phragmites is the ultimate parent in terms of reproductive success, allowing it to increase in area by 25% since 1971 in the Rhode River subestuary. While phragmites can spread asexually through rhizome clones, seed dispersion requiring two parents was the most successful tactic found in this study. Kari St.LaurentI received a Ph.D. in oceanography in […]
Male squid can vary the effort they put into each mating event. Find out what type of female makes the males put in the most energy. Sarah GiltzI am a doctoral candidate in Ecology and Evolutionary Biology at Tulane University. My research focuses on the larval dispersal and development of the blue crab in the […]
A female eagle ray gives birth to two female pups. But she has been housed in a tank without any sexually mature males. Is it a miracle or is there some logical explanation? Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the sensory biology of deep-sea fishes. I […]
Finding a date on Valentine’s Day can be hard! Whether you are single or in a relationship, we are trying to make your week a little brighter by sharing some tales of romance from the ocean. Today we will look at the answer some fishes have found for not being able to find a suitable […]
It might be hard for a box jellyfish to buy into the old adage “sex sells,” especially when their gonads are laced with stinging cells. This is just one bizarre adaptation in these organisms, read on to find out more! Gordon OberPostdoctoral Researcher, Claremont McKenna College I am currently a postdoc at Keck Sciences, Claremont […]
Researchers in Australia investigated whether sea urchin sperm are going to make it through an acidified ocean or if they’ve reached their tipping point. Read on to learn more! Erin McLeanHi and welcome to oceanbites! I recently finished my master’s degree at URI, focusing on lobsters and how they respond metabolically to ocean acidification projections. […]
