Developing a novel approach to analyse the regimes of temporary streams and their controls on aquatic biota [PDF]

, 2011
Temporary streams are those water courses that undergo the recurrent cessation of flow or the complete drying of their channel. The biological communities in temporary stream reaches are strongly dependent on the temporal changes of the aquatic habitats ...

Contrasting effects of temperature across trophic levels in geothermally warmed soil food webs

Oikos, EarlyView.
Global warming is altering the structure and dynamics of ecological communities, with significant consequences for soil food webs. Rising temperatures are expected to accelerate metabolic rates in organisms, potentially altering species interactions, and the structure and energetics of food webs.

The effects of single versus successive warm summers on an intertidal community

Oikos, EarlyView.
To accurately predict how organisms and ecological communities will respond to future conditions caused by climate change, we must consider the temporal dynamics of environmental stressors, including the effects of repeated exposures to stress. We performed a two‐year passive thermal manipulation in coastal British Columbia, Canada to determine how ...

Modeling of the distribution of 137Cs radionuclide in the Didoriv’s ponds cascade

Ядерна фізика та енергетика, 2016
Basic model of 137Cs radionuclide transfer in the Didoriv’s ponds cascade was created. Monitoring studies of cascade was conducted. On the basis of the field observation data, dynamics of the basic model holding in different chambers and system ...

‘Should’ and ‘can’ active restoration be used in biodiversity offsets? Stakeholder perspectives from New South Wales, Australia

People and Nature, EarlyView.
Abstract Despite their controversial nature, biodiversity offsets are often used as a regulatory tool to counterbalance the impacts of land clearing on biodiversity. Offsets usually aim to achieve no net loss (NNL) of biodiversity through protection and/or restoration of habitat.

Evaluation of Four Supervised Learning Methods for Benthic Habitat Mapping Using Backscatter from Multi-Beam Sonar

Remote Sensing, 2012
An understanding of the distribution and extent of marine habitats is essential for the implementation of ecosystem-based management strategies. Historically this had been difficult in marine environments until the advancement of acoustic sensors.

Sporormiella as a tool for detecting the presence of large herbivores in the Neotropics [PDF]

, 2016
The reliability of using the abundance of Sporormiella spores as a proxy for the presence and abundance of megaherbivores was tested in southern Brazil. Mud-water interface samples from nine lakes, in which cattle-use was categorized as high, medium, or ...

Biogeographic regions and events of isolation and diversification of the endemic biota of the tropical Andes

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance This study unifies quantitative methods with dated molecular phylogenies of different lineages to identify biogeographical regions and understand the spatial and temporal evolution of the biota in one of the most biodiverse hotspots of the ...
