Long-term Effects of Climatic Change on Fish Species DiversityEntry ID: USDA0555
Abstract: The primary objective of "Long-term Effects of Climatic Change on Fish
Species Diversity" is to understand the long-term effects of climatic
change on fishes, particularly Semionotus. The goal is to investigate
speciation and extinction in fishes both in terms of the organism's
ability to respond to environmental perturbations and in relation to
environmental changes such as global climatic ... change and continental
Collection Organization: Cornell University
Collection Methodology: Biogeographic survey based on seven major
research collections and several smaller ones that together include
faunal samples from 50 different localities in 11 distinct lake
basins. About 1500 specimens have been examined and, in this project,
another 1000 will be studied. Specimens will be identified, measured
using computer-assisted techniques, and their temporal and geographic
localities recorded. Once this biogeographic database is constructed,
"survivors" and endemics will be identified and then tested
statistically for differences in morphological characteristics.
Collection Frequency: Ongoing research.
Update Characteristics: N/A
Data Center: Cornell University
Dissemination Media: Paper-based publications.
Access Instructions: Contact the data center.
