Data from: Parallel declines in abundance of insects and insectivorous birds in Denmark over 22 years
负责人:
M?ller, Anders Pape
关键词:
insect abundance species decline
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

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

摘要:
Environmental DNA (eDNA) sampling has emerged as a powerful tool to detect and quantify species abundance in aquatic environments. However, relative
