Multi‐scale patterns in the occurrence of an ephemeral pool‐breeding amphibian
Species distributions are governed by processes occurring at multiple spatial scales. For species with complex life cycles, the needs of all life stages must be met within the dispersal limitations of the species.

Scientific Productivity of Brazilian Ecological Stations [PDF]
SummaryProtected areas are frequently used loci for ecological and conservation research, with several national/international designations identifying scientific research as a key objective. For example, Ecological Stations (ESs) in Brazil are strictly protected areas with the explicit goals of protecting nature and hosting scientific research ...

Influence of gas stations on the ecology of the urban environment [PDF]
The aggravation of the environmental situation in major cities of the Russian Federation has been observed in recent years. A significant contribution to the deterioration of the quality of the urban environment has a large number of vehicles and consequently the number of gas stations. They are generally concentrated within the city limits.
