Migration

9.0K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

Frequency-dependent Selection01:21

Frequency-dependent Selection

24.4K
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.

Epiphytes, Parasites, and Carnivores

17.0K
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...

Summary
This summary is machine-generated.

High-elevation trees are more suitable insect hosts due to increased leaf nitrogen and lower tannins, supporting the atmospheric deposition hypothesis. This finding impacts herbivore population dynamics in the northeastern United States.

Area of Science:

  • Ecology
  • Forestry
  • Entomology

Background:

  • Conspecific trees at different elevations face varied conditions, influencing insect herbivore suitability.
  • Two hypotheses explain altitudinal differences: temperature constraints on growth versus increased palatability from atmospheric nitrogen deposition.

Purpose of the Study:

  • To evaluate the temperature and atmospheric deposition hypotheses regarding insect herbivory on high- and low-elevation trees.
  • To compare foliar chemistry and insect growth rates between high- and low-elevation tree populations.

Main Methods:

  • Insect bioassays using Lymantria dispar larvae were conducted.
  • Foliar nitrogen and condensed tannin levels were analyzed.
  • Simulated atmospheric nitrogen deposition was applied to valley trees.

Main Results:

  • High-elevation trees exhibited higher leaf nitrogen and supported greater insect growth rates.
  • Foliar chemistry of high-elevation trees (higher nitrogen, lower tannins) indicated greater host suitability.
  • Simulated nitrogen deposition altered valley tree chemistry, mimicking high-elevation traits.

Conclusions:

  • The atmospheric deposition hypothesis is broadly supported, explaining increased host suitability of high-elevation trees.
  • Atmospheric nitrogen deposition influences spatial patterns of herbivory and herbivore community composition.
  • Elevational differences in tree chemistry and host suitability are linked to nitrogen deposition patterns.
