Epiphytes, Parasites, and Carnivores

Epiphytes, Parasites, and Carnivores

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...

Types of Selection

Types of Selection

Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Optimal Foraging

Optimal Foraging

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.

Frequency-dependent Selection

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Summary

Hyla cinerea frogs prefer different prey in the wild versus the lab. Prey selection depends on insect length, activity, and specific behaviors, influencing feeding success.

Area of Science:

Ecology
Zoology
Animal Behavior

Background:

Hyla cinerea, the green treefrog, is a common amphibian predator.
Understanding amphibian feeding ecology is crucial for ecosystem dynamics.

Purpose of the Study:

To investigate prey selection by Hyla cinerea in both field and laboratory settings.
To identify key factors influencing prey choice in Hyla cinerea.

Main Methods:

Field observations of Hyla cinerea diet.
Laboratory feeding experiments with various insect prey.
Analysis of prey characteristics: length, activity, and behavior patterns.

Main Results:

Spodoptera (Lepidoptera) and Chauliognathus (Coleoptera) larvae are primary field prey.

Musca (Diptera) is the most preferred prey in laboratory settings.

Prey length, activity, and specific behaviors significantly influence Hyla cinerea prey selection.

Conclusions:

Hyla cinerea exhibits differential prey selection based on environment (field vs. lab).
Prey characteristics, including behavior and morphology, are critical determinants of predation success.
