Summary
This summary is machine-generated.Green sea turtles (Chelonia mydas) were observed feeding on terrestrial frangipani leaves in Costa Rica. This suggests fallen leaves may be a common food source for turtles near coastal trees, even during mating seasons.
Area Of Science
- Marine Biology
- Herpetology
- Behavioral Ecology
Background
- Green sea turtles (Chelonia mydas) are primarily herbivores, with their diet typically consisting of seagrasses and algae.
- Coastal ecosystems, including mangrove forests and areas with deciduous trees, provide unique foraging opportunities.
- Understanding dietary flexibility is crucial for the conservation of sea turtle populations.
Purpose Of The Study
- To document an unusual feeding behavior in a green sea turtle.
- To investigate the potential role of terrestrial plant matter in the diet of green sea turtles.
- To assess if male green sea turtles forage during their reproductive periods.
Main Methods
- Direct observation of an adult male green sea turtle feeding.
- Identification of the terrestrial plant species consumed (frangipani, Plumeria rubra).
- Location of the observation: Cabuyal, a known sea turtle nesting beach on the North Pacific coast of Costa Rica.
Main Results
- An adult male green sea turtle was observed consuming fallen frangipani leaves.
- This feeding behavior occurred in the marine environment adjacent to a coastal terrestrial habitat.
- The observation supports the hypothesis that terrestrial leaves can be a food source for green turtles near coastal vegetation.
Conclusions
- Terrestrial leaves, such as frangipani, may constitute a significant, yet underreported, food item for green sea turtles in specific coastal areas.
- Male green sea turtles may engage in foraging activities during reproductive periods when suitable food resources are available.
- This dietary flexibility highlights the importance of coastal vegetation adjacent to marine habitats for sea turtle foraging ecology.

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
Optimal foraging theory states that natural selection favors foraging strategies that balance the benefits of a particular food, such as energy and nutrients, with the costs of obtaining it, such as energy expenditure and the risk of predation. Optimal foraging maximizes benefits while minimizing costs.
For the Crows
All organisms in an ecosystem occupy a trophic level in the food chain. The lowest level consists of primary producers, which synthesize their food from either solar or chemical energy. Each subsequent level obtains energy from the levels below. Detritivores can occupy any of the levels above primary producers.
Food Chains
Within an ecosystem, energy and nutrients flow through organisms in a sequential order known as a food chain. Each organism occupies a trophic level or a specific place...
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).
Net Production Efficiency
Energy flows through ecosystems, from one organism to the next. However, only the energy stored in an organism as biomass is available as food for the next...
The diverse plant life on Earth—consisting of nearly 400,000 species—can be divided into three broad categories based on biological characteristics: nonvascular, seedless vascular, and seed plants.
Nonvascular Plants Were the First Plants on Earth
Nonvascular plants that live today include liverworts, mosses, and hornworts—collectively and informally known as bryophytes.
Nonvascular plants are characterized by a lack of extensive vascular tissue, and have no true roots,...
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...
