Local Environmental Variables Predict Fish Species Richness and Composition in Sand Beaches of a Neotropical River

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Local and regional species diversity is influenced by historical factors, resource availability, biotic interactions, the presence of resources, and adequate environmental conditions. We evaluated the effects of local environmental variables and spatial structure on fish species richness and composition along sandy beaches of a Neotropical ...

Hydrologic Connectivity and Secondary Channel Habitat Properties of the Lower Mississippi River, a Large, Meandering River in the Southern USA

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT In large, meandering rivers, much of the instream flow veers around islands through secondary channels (SCs), which often comprise a substantial proportion of a river's longitudinal path. Due to their dissimilar hydrological conditions, within and among themselves and to the main channel (MC), SCs augment habitat diversity and biogeochemical ...

Different Aspects of the Fundamental Spatial Planning Pattern of Iran

open access: yesتحقيقات جغرافيايی, 2018
The spatial planning rank as an interdisciplinary subject, has currently regained its status in many countries. Yet we cannot lose sight of the fact that, in certain cases, it has not achieved resounding success.

Alpine greening deciphered by forest stand and structure dynamics in advancing treelines of the southwestern European Alps

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Multidecadal satellite observations, like those from Landsat, enable the study of vegetation greenness trends at extensive spatial and temporal scales. Alpine ecosystems show significant increases in vegetation greenness, but the ecological processes driving this greening are less understood.

Short‐term forest harvesting effects on emergence rates of aquatic insects from small streams treated with different riparian management

open access: yesJournal of Applied Ecology, EarlyView.
These results highlight the detrimental impact of harvesting along stream ecosystems where riparian buffer width is insufficient and demonstrate that a 30‐m buffer may offer substantial protection, strengthening the scientific foundation for sustainable riparian forest management.
