Diversity and Composition of Aquatic and Riparian Plants in Lake Tondano, North Sulawesi

Biosfer: Jurnal Tadris Biologi
Aquatic and riparian vegetation plays a fundamental role in maintaining freshwater ecosystem structure, biodiversity, and ecological processes. However, increasing environmental pressures have altered vegetation communities in many tropical lakes ...

Ecological scale mediates nonlinear relationships of animal nutrient excretion with dissolved organic matter

Journal of Animal Ecology, EarlyView.
We show that nutrient excretion by vertebrates and invertebrates varies nonlinearly with dissolved organic matter concentration and composition and by taxonomic rank, with stronger patterns at the individual compared to the community level. Our findings highlight the importance of examining animal‐mediated nutrient cycling across taxa and ecological ...

Optimized Stratification for Mapping Riparian Vegetation in Arid and Semiarid Environments

, 2019
This paper describes a method of mapping riparian vegetation in semi-arid to arid environments using the Landsat normalized difference vegetation index (NDVI). The method successfully identified a range of riparian community types across the entire state

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Longitudinal dimensions of land-use impacts in riverine ecosystems

Acta Limnologica Brasiliensia
: Aim Rivers are linked longitudinally via the flow of water and the spatial dimensions of the changes in local riparian vegetation are still poorly understood.

Consistent Choice of Prey Source Habitat Across Diverse Landscapes by a Selective Insectivorous Bat

Integrative Zoology, EarlyView.
After analyzing the diet of the greater horseshoe bats in three distinct colonies, we identified significant spatial and temporal differences, particularly noting a stronger reliance on riparian habitats in Mediterranean areas. The species exhibits great ecological adaptability with strong plasticity in prey source habitats, shifting preferences among ...

The Effects of Streamflow Regulation of Riparian Vegetation

, 1987
A study of the effects of streamflow regulation on riparian vegetation focused on seedling establishment along 30 low-gradient, alluvial streams throughout central California. Initial establishment densities were generally lower on regulated streams than along non-regulated ones.

Extinction Debt Paid Off: The Demise of the European Polecat (Mustela putorius) in NE Iberia

Integrative Zoology, EarlyView.
We studied a vanishing polecat population for a decade, until its ultimate demise, using camera trap and roadkill data, landscape descriptors and dietary and toxicological analyses.Polecat favoured farmland and avoided forests and water bodies occupied by the invasive American mink.

Spatial Patterns of Avian Stable Isotopes Reveal Ecological Impacts of Climate and Land‐Use Change

Integrative Zoology, EarlyView.
Increased feather δ15N values with pasture coverage reveal an elevated baseline δ15N in grazing landscapes, while broader isotopic niches in farmland habitats reflect agricultural expansion's significant influence on resource use patterns of the avian community.

Diversity and Species Richness of Lepidopteran Stemborers and Their Host Plants Across Major Vegetation Mosaics of East Africa. [PDF]

Ecol Evol
Lepidopteran stemborer populations in wild habitats are increasingly influenced by anthropogenic disturbances, including urbanization and agricultural intensification in addition to climate change, which alter community composition and diversity within fragmented native ecosystems.
