Bison are highly efficient grazers that convert forage into high-quality protein, making growth efficiency an important factor in livestock production. Weight per day of age (WDA) is a key m…
ISEF · 2026
Animal Sciences Second Award
Pygmy and dwarf sperm whales (Kogia breviceps and Kogia sima) are deep-diving cetaceans with limited internal health data due to low visibility. Necropsies often reveal stomach infestations…
CSEF · 2026
Zoology (Senior Division) First Award
Predator-prey interactions often involve temporal sequences of sensory cues, where predator-derived chemical signals are detected by the prey before physical contact occurs. Whether prey neu…

Animal Sciences
Bees pollinate the flowers of many fruit trees which produce a significant proportion of our food supply. It is therefore important to improve beekeeping practices to produce healthier bees…
CSEF · 2026
Zoology (Junior Division) Second Award
The goal of this experiment was to observe the effect that different extreme conditions had on the speed and mobility of Hypsibius exemplaris, an animal from a species of microscopic inverte…
CSEF · 2026
Zoology (Senior Division) Fourth Award
Honeybees (Apis mellifera) are essential pollinators sustaining agricultural productivity and ecosystem stability but are severely threatened by the parasitic mite Varroa destructor, a prima…
ISEF · 2026
Animal Sciences Fourth Award
Traditional begging signals given by the altricial young of birds serve to communicate need to parents and solicit provisions during feeding visits. Such signals often incur costs, like pred…

Animal Sciences
In this project, the major aim is to identify the relationship that exists between the sound type and the level of stress in the dogs. In this project, there are three dogs. Each dog is expo…
CSEF · 2026
Zoology (Junior Division) Honorable_mention Award
Basal cell carcinoma (BCC) is driven by abnormal activation of the Hedgehog (HH) signaling pathway through the Smoothened (SMO) receptor. HH signaling also regulates regeneration and posteri…
ISEF · 2026
Animal Sciences
I was investigating and tracking the kinds of pollen that different colonies were collecting. Specifically local hives vs. domesticated hives. I compared four different hives, two which were…
ISEF · 2026
Animal Sciences
Microplastics are emerging environmental contaminants that have been detected in diverse ecosystems and biological systems. Increasing evidence suggests that these particles can induce oxida…
ISEF · 2026
Animal Sciences Fourth Award
Raw fish (sashimi) consumption is common in Japan, and angle-dependent coloration is regularly observed during meals. Although similar coloration has been reported in meat, few studies have…
ISEF · 2026
Animal Sciences
Honeybees exhibit trophallaxis, a behavior in which a recipient extends their proboscis to drink a nectar droplet held by the donor's mouthparts. During this process, the recipient's antenna…
CSEF · 2026
Zoology (Senior Division)
Tardigrades are eight legged microscopic invertebrates that are known for their ability to survive in extreme conditions by entering “tun” state, which is regulated by internal reactive oxyg…
ISEF · 2026
Animal Sciences
Local anesthetics are used to temporarily block nerves from transmitting pain signals during invasive medical procedures. Complications can arise when large doses are inadvertently administe…
ISEF · 2026
Animal Sciences
Microplastic pollution is an emerging environmental health threat, with polystyrene microplastics detected in water, food, and even our blood. Their toxicity arises from leachable endocrine-…
ISEF · 2026
Animal Sciences
Numerous factors can affect avian biodiversity including air temperature, precipitation, wind, and air quality. This study aimed to determine how these meteorological and wildfire-related fa…
ISEF · 2026
Animal Sciences
Crayfish are a keystone species in freshwater ecosystems, meaning that disruptions to their behavior can cascade through the entire environment. Building upon statistically significant 2025…

Zoology (Junior Division)
Disasters can have a big effect on ecosystems and survival of different species. The goal of this experiment is to study how droughts and famine affect animals, specifically ants. Ants have…
CSEF · 2026
Zoology (Senior Division)
My project investigates the effects of magnesium chloride (hexahydrate) on the regeneration speeds of planaria, a low-level invertebrate flatworm. Planaria are well known for their exception…
CSEF · 2026
Zoology (Senior Division)
Global warming is raising the core temperature of the earth slowly. Temperature is known to have an effect on the metabolism of insects, thus speeding up their growth and development. Furthe…
