Belligerent Birds: Do penguins perform unprompted acts of aggression?

Adélie penguins lead busy lives mating, reproducing, and avoiding being eaten. They can do all this from the safety of their colonies. Recently however, scientists discovered penguins roaming outside of their colonies and attacking other bird species. Is there a reason for these attacks, or are these penguins simply aggressive? Francesca GiammonaI am a PhD […]

Bearing teeth: How polar bear dental health can illustrate climate change

It is no secret that climate change is damaging Arctic ecosystems. Because of melting sea ice, Arctic species have had to change their behaviors in order to survive. Polar bears in particular have been spotted eating new and strange diets. But what do these diets consist of, and are they causing harm to this species? […]

Sleeper Sharks: From the jaws of defeat

There are many stories of species close to extinction. Sometimes, species can go locally extinct, disappearing from a particular area. Once this happens, is it possible for species to return to that area? What can humans do to help these species come back? A success story from the Galapagos shark may hold some answers. Francesca […]

The Otter Guys: How heavy metal pollution affects Alaskan northern sea otters

Most pollution is clearly visible in nature, but some types are very subtle. In the case of heavy metal pollution, its effects are nearly invisible, mostly causing harm to the internal organs of animals at the top of marine food chains. How does this pollution affect endangered otter populations, and is it a cause for […]

Killer Consequences: How boats affect the behavior of endangered killer whales

Killer whales are famous for their intelligence and athletic prowess in (and leaping out of) the water. However, for some killer whale populations, human activity on the water can negatively impact their lives. Just how bad is this impact, and does it differ between male and female whales? Francesca GiammonaI am a PhD candidate at […]

Cuttlefish Cognition: are these oceanic invertebrates capable of learning?

The science of animal behavior has become more focused on figuring out the intellectual capacity of non-human, and particularly non-mammalian, animals in recent years. Cuttlefish have now taken the spotlight, and in a recent study, scientists ask the question: can these small marine animals learn, and make decisions based on past experiences? Francesca GiammonaI am […]

Whistle While you Work (for Lunch): Dolphin Communication Techniques During Foraging

Dolphin groups, or pods, need every member working together to communicate and find food. To do this, dolphins whistle to each other. But when humans, and their boats, are in a pods’ natural territory, do dolphins have to change their whistling and feeding behavior in order to successfully chow down? Francesca GiammonaI am a PhD […]

Cold Water Conundrum: How does unusually cold water affect fish growth?

With the threat of climate change ever present, many of us focus on the negative effects of unusually warm water on fish species. But, can abnormally cold water also hurt fishes, and can it hurt different fishes in different ways? Francesca GiammonaI am a PhD candidate at Wake Forest University, and I received a B.S. […]

Microplastics, Canned Fish, and You: How plastic pollution may play a role in your next lunch

Did you know that many plastic items can shed tiny particles called microplastics? These microplastics are present everywhere in our environment, from the sea to the air. But how prevalent are they, and do they pose harm to humans? Researchers attempted to answer this question by studying a common food item – canned fish. Francesca […]

Fish and Fecal Figs: How does the size of one fish affect fig seed growth?

Let’s think of well-known relationships between two different species. Sharks and remoras, hippos and small birds, and….fish and fig seeds? How does one species of fish help fig trees to grow, and how is this plant growth affected by the growth of the fish themselves? Francesca GiammonaI am a PhD candidate at Wake Forest University, […]

Shark Smarts: Can associative learning change shark behavior?

We all know that sharks are excellent hunters, but can the instinctual predatory mind of one of the ocean’s apex predators be influenced by the fishing actions of humans? Can sharks learn to feed differently based on human presence? Francesca GiammonaI am a PhD candidate at Wake Forest University, and I received a B.S. in […]

Can Corals Recover from the Effects of Climate Change?

With climate change becoming a more pressing issue, the world’s coral reefs are suffering heavy consequences. Corals are increasingly becoming bleached, which can lead to reef death. But are there ways for corals to recover from bleaching? Francesca GiammonaI am a PhD candidate at Wake Forest University, and I received a B.S. in Biology from […]

Fat Burning Mode: How one fish survives out of water

Water and air are very different environments. How can a fish with a body built for the water spend time on land when it can’t effectively eat or use its gills? The answer lies with the fish’s ability to alter its metabolism. Francesca GiammonaI am a PhD candidate at Wake Forest University, and I received […]
