Southeast Asian riverine fishes are classified into three guilds (‘black’, ‘white’ and ‘grey’ species) based on their reproductive migration strategies. In this study, we aimed to investigate whether fish morphology could be used predict the Mekong guilds. Nine dimensionless ratios of morphological traits were describe locomotion food acquisition strategies 121 species. The links between assess...

A fundamental premise of landscape ecology is that finer-scaled local ecological integrity is directly influenced by larger-scaled land use patterns. Therefore, characterizing landscape patterns that are mapped from satellite imagery may provide valuable covariate information about average integrity “on the ground”. This conjecture was evaluated in Pennsylvania for 102 watersheds where land cov...

The expansion of eucalypt forestry worldwide has been accompanied by accidental and deliberate introductions of Australian insects associated with eucalypts. Local insect species have also colonized introduced eucalypts in many regions. This situation provides a unique opportunity to observe the development of new insect communities across trophic levels. Here the history of Australian invaders...

Introduction: Health organizations are required to raise people’s awareness about foodborne diseases and to control and prevent these diseases. Training courses held by guilds are aimed to enhance food hygiene in the society. The present study was conducted to determine the effect of training courses on the awareness, attitude, and performance of confectionery, bakery, and restaurant workers. ...

Previous observations in riparian habitats of Kings Creek, Konza Prairie Research Natural Area, Kansas indicated that emerging aquatic insects represent a concentrated source of food for insectivorous birds, particularly the flycatcher and gleaner guilds. This hypothesis was tested by concurrent measurements of net insect emergence (total emergence minus adults returning to the stream) and dens...

Our goal was to identify herbivory patterns from two insect guilds associated with Cnidoscolus quercifolius in a tropical deciduous forest in northeastern Brazil. We sampled four different habitats: (1) forest edge, (2) mesic (near to the perennial water source), (3) forest interior and (4) rupestrian fields. Habitat edge had lower leaf damage than rupestrian, mesic and forest interior habitats...

One of the most influential gaming trends today, Massively Multi Online Role Playing Games (MMORPG), poses new questions about the interaction between the players in the game. Previous work has introduced concepts such as community, commons, and social dilemma to analyze situations where individual choices may result in suboptimal global results. We propose to use the concept of norms instead. ...

Between 2006 and 2013, we salvaged and necropsied 362 seabird specimens from Tern Island, French Frigate Shoals, Northwestern Hawaiian Islands. Plastic ingestion occurred in 11 of the 16 species sampled (68.75%), representing four orders, seven families, and five foraging guilds: four plunge-divers, two albatrosses, two nocturnal-foraging petrels, two tuna-birds, and one frigatebird. Moreover, ...

The aim of the present study was to find underlying factors of social capital acquisition in online gaming communities (guilds). 391 players of World of Warcraft were asked about their playing habits, their behavior towards fellow players and the bridging and bonding social capital they received by playing. Path analysis revealed five underlying factors of social capital formation in guilds. Ou...

In plant-pollinator communities many pollinators are potential generalists and their preferences for certain plants can change quickly in response to changes in plant and pollinator densities. These changes in preferences affect coexistence within pollinator guilds as well as within plant guilds. Using a mathematical model, we study how adaptations of pollinator preferences influence population...
