To explore how plants may influence dispersal of their own seeds by manipulating the behavior and physiology dispersers, we studied effect a soluble chemical (or chemicals) in fruits Witheringia solanacea (Solanaceae), Costa Rican cloud forest shrub, on passage its through guts one major Black—faced Solitaire, Myadestes melanops (Muscicapidae: Turdinae). Using artificial containing natural seeds, found that presence crude pulp extract reduced median seed retention time nearly 50%. Estimation...
Xantus' Murrelets (Synthliboramphus [Endomychura] hypoleucus) were studied on Santa Barbara Island, California from 1975 to 1979. Clutch initiation occurred March June and usually peaked in April. The two-egg clutch was 45% of the female's weight. Eggs laid eight days apart. Both sexes shared duties during a 34-day incubation period; partners relieved one another every three four days. typically left unattended interval between laying successive eggs, immediately after completion,...
Collisions with buildings cause up to 1 billion bird fatalities annually in the United States and Canada. However, efforts reduce collisions would benefit from studies conducted at large spatial scales across multiple study sites standardized methods consideration of species- life-history-related variation correlates collisions. We addressed these research needs through coordinated collection data on (35), Canada (3), Mexico (2). collected all carcasses identified species. After removing...
Fruit preference by birds is a complex process based upon the morphology and spatial arrangement of fruits on physiological needs capabilities birds. In North America, most can be divided into two groups nutritional content: those rich in sugars relative to lipids, lipids sugars. To investigate how fruit may change seasonally determine if it correlated with state, we designed simple laboratory experiment using American Robins (Turdus migratorius) artificial fruits. During summer autumn,...
Landscape-scale alterations that accompany urbanization may negatively affect the population structure of wildlife species such as freshwater turtles. Changes to nesting sites and higher mortality rates due vehicular collisions increased predator populations particularly immature turtles mature female We hypothesized proportions adult in a will correlate with landscape urbanization. As collaborative effort Ecological Research Education Network (EREN), we sampled turtle 11 states across...

To help introductory biology students understand how plants will respond to higher levels of CO<sub>2</sub>, we have created a multi-week module consisting series four related laboratory lessons. These lessons allow make connections among morphological, physiological, and growth responses <em>Brassica rapa</em> (Fast Plants®)<em> </em>to low (400 ppm) high (800 concentrations atmospheric carbon dioxide (CO<sub>2</sub>). Elevated CO<sub>2</sub> was chosen as an environmentally relevant...
