Data from: Parallel declines in abundance of insects and insectivorous birds in Denmark over 22 years
- 负责人：
- M?ller, Anders Pape
- 摘要：
- Farmers in most western countries have increased use of fertilizer and pesticides with impact on wild animals and plants, including the abundance
Data from: Territory size decreases minimally with increasing food abundance in stream salmonids: implications for population regulation
- 负责人：
- Grant, James
- 关键词：
- contiguous territories density limitation population density stream salmonids territoriality elastic disc model
- 摘要：
- educing territory size will be inefficient; a 20-fold increase in food abundance would be required to double population density. Our analysis may also have implications
Data from: Altitude shapes the environmental drivers of large-scale variation in abundance of a widespread mammal species
- 负责人：
- 关键词：
- 摘要：
- ropean badger (Meles meles), across France. We used (1) direct detections of 9,439 dead and living badgers, from 2006 to 2009, to estimate badger relative abundance
Data from: Climate and local abundance in freshwater fishes
- 负责人：
- 摘要：
- al factors regulating local abundance. While range-wide variation in population abundance associated with environmental conditions has been investigated in terrestrial
Data from: Crossing the (Wallace) line: local abundance and distribution of mammals across biogeographic barriers
- 负责人：
- 摘要：
- regions. But the consequences of these translocations are difficult to predict. We compared local abundance and distributions in four tropical mammal
Data from: Abundance and extinction in Ordovician-Silurian brachiopods, Cincinnati Arch, Ohio and Kentucky
- 负责人：
- 摘要：
- e found conflicting patterns, indicating a more complex relationship between abundance and extinction in the geologic past. This study tests the relationship bet
Data from: A closer examination of the 'abundant center' hypothesis for reef fishes
- 负责人：
- 摘要：
- to Atlantic reefs. Methods: We used underwater visual estimates of fish abundance, containing 22,963 transects and 1,215 species. For each species
Data from: Are exotic plants more abundant in the introduced versus native range?
- 负责人：
- 摘要：
- controls within the native range to attain higher abundance in the introduced range. However, introductions may also allow inherently successful species access to new regions wher
Data from: Experimental reduction of plant abundance changes interaction frequency of a tri-trophic micro-food web: contrasting responses of gene
- 负责人：
- 摘要：
- seed predators. 3. The neutral process hypothesis posits that network topology and interaction frequency are determined by the relative abundances
Data from: Environmental DNA analysis of river herring in Chesapeake Bay: a powerful tool for monitoring threatened keystone species
- 负责人：
- 摘要：
- Environmental DNA (eDNA) sampling has emerged as a powerful tool to detect and quantify species abundance in aquatic environments. However, relative
