Abstract By studying substrate (choriotope) preferences of 25 caddisfly taxa in the Schreierbach stream, a calcareous, first order tributary Ybbs river (Lower Austria), we aimed on (1) detecting microhabitat space and time, (2) to relate this information with ontogenetic choriotope shifts, (3) explore relationships between feeding guilds choriotopes chosen. For this, took six sets bi-monthly mu...

This study presents a methodology for combining archival data storage tags (DSTs) and ultrasonic transmitters to investigate the microhabitat conditions of adult Cancer magister (Dana), inhabiting an estuary. The temperature, salinity and depth experienced by freeranging Dungeness crabs was recorded at 10min intervals for periods ranging from 1 week to 8months. Crabs were tracked using a hydrop...

We compare lizard assemblages of Cerrado and Amazonian savannas to test the ecological release hypothesis, which predicts that niche dimensions and abundance should be greater in species inhabiting isolated habitat patches with low species richness (Amazonian savannas and isolated Cerrado patches) when compared with nonisolated areas in central Cerrado with greater species richness. We calculat...

Cancer is now understood to be a process that follows Darwinian evolution. Heterogeneous populations of cancerous cells that make up the tumor inhabit the tissue 'microenvironment', where ecological interactions analogous to predation and competition for resources drive the somatic evolution of cancer. The tumor microenvironment plays a crucial role in the tumor genesis, development, and metast...

Forest ecosystems have a distinct vertical dimension, but the structuring of communities in this three-dimensional space is not well understood. Water-filled tree holes are natural microcosms structured metacommunities. Here, we used these as model systems to analyze how insect and occurrence abundance individual species influenced by biotic abiotic microhabitat characteristics, position hole, ...

The distinction between concrete and abstract concepts is psychologically valid but so far it can hardly be quantified in any objective way, which prevents it from being further studied in computational linguistics. This paper proposes a systematic way to measure concreteness from the surface structure of dictionary definitions. Comparing the scores from WordNet definitions with human ratings, ...

In most developed countries, gender equality and neutrality have been widely promoted and embraced— through public policy—as a socio-cultural goal since at least the mid-twentieth century. Accordingly, we predicted that a population of highly educated youth from a relatively wealthy developed country (mostly students from a Canadian university) would display little or no significant gender bias...

Food manufacturers need to understand the taste preferences of their consumers in order to develop successful new products. The existence of consumer segments that differ in systematic ways in their taste preferences can have important implications for product development. Rather than developing a product to please all potential consumers, the manufacturer may decide to optimize the product for...

The main aim of the present study was to scrutinize substrate and microhabitat preferred by Himalayapotamon emphysetum under laboratory conditions. In first experiment, different substrates: gravel, stones, cobbles were placed in round plastic containers, second experiment: grass, aquatic plants, wood fragments used as microhabitats for analyzing preference crab species. Minimum mortality obser...
