Insects are a hyper diverse and ecologically important group. Their high diversity, however, presents challenges in sampling methodology, because rare species unreliably detected with low effort. However, the relationship between effort detections, critical for effective monitoring evaluation of population trends, is too seldom quantified. We sampled forest beetles 3 months 4-ha stand mixed dec...

this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...

Neotropical rainforests sustain some of the most diverse terrestrial communities on Earth. Euglossine (or orchid) bees are a diverse lineage of insect pollinators distributed throughout the American tropics, where they provide pollination services to a staggering diversity of flowering plant taxa. Elucidating the seasonal patterns of phylogenetic assembly and functional trait diversity of bee c...

Species richness is the most commonly used but controversial biodiversity metric in studies on aspects of community stability such as structural composition or productivity. The apparent ambiguity of theoretical and experimental findings may in part be due to experimental shortcomings and/or heterogeneity of scales and methods in earlier studies. This has led to an urgent call for improved and ...

The concept of sustainability is encouraged to preserve natural resources, social values, cultural heritage, and economic capital, which already exist to make available them for the next generations. Moreover, to enhance the level of sustainability in communities, numerous scholars indicated both individual and community identities play a crucial role. Sustainability is attainable and successfu...
