Macrobenthic Assemblages and the Influence of Microhabitat in a High-Mountain Lake (Northwest Italy)

Diversity
High-mountain lakes are freshwater ecosystems situated above the tree line which are known for their remote locations and limited accessibility. These ecosystems host simplified biotic communities primarily concentrated in the littoral zone and dominated

Abundant prey or optimal microhabitat? Natrix tessellata stays hidden in safe areas in a diverse floodplain along the Danube at Göd, Hungary [PDF]

, 2013
Natrix tessellata (Laurenti, 1768) is a diurnal piscivorous Eurasian snake species with a large distribution area. Along the River Danube it is present in the floodplain and along the lower stretch of tributaries. The distribution of N.

Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

Oikos, EarlyView.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

Predicting Occupancy of Wintering Migratory Birds: Is Microhabitat Information Necessary? [PDF]

, 2012
Information regarding microhabitat, here defined as small-scale vegetation structure, is often useful in predicting use of habitat by birds. Quantifying microhabitat, however, is expensive and labor intensive compared to assessment of habitat at a larger

Bottom–up and top–down drivers influence urbanization effects on insect herbivory in oaks

Oikos, EarlyView.
Urban forests provide essential ecosystem services, including pest control, biodiversity conservation, and human health benefits. Herbivory is a widespread biotic interaction that shapes ecosystem functions, such as primary productivity and soil fertility, which underpin these services.

Distribution of fish among Avicennia and Sonneratia microhabitats in a tropical mangrove ecosystem in South China

Ecosphere, 2019
Mangrove structural complexity plays an important role in the way fish using their habitat. However, the effects of structural attributes on fish spatial distribution remain uncertain.

On the spatial clustering of behavioural phenotypes: matching movement tactics with landscape structure in a large herbivore

Oikos, EarlyView.
In the wild, individuals consistently differ in movement and space use behaviours, depending on their personality. This variation can lead to personality–habitat associations and spatial structuring, potentially generating individual niche segregation.

Bryophyte diversity in karst sinkholes affected by different degrees of human disturbance

Acta Societatis Botanicorum Poloniae, 2019
The diversity of bryophytes in karst sinkholes has received little attention, and these habitats probably play a crucial role as refugia. In this study, bryophyte diversity affected by different levels of human disturbance in five karst sinkholes was ...
