Bees are critically important for ecosystem function and biodiversity maintenance through their pollinating activity. Unfortunately, bee populations are faced with many threats, and evidence of a massive global pollination crisis is steadily growing. As a result, there is a need to understand and, ideally, predict how bees respond to pollution disturbance, to the changes over landscape gradients, and how their responses can vary in different habitats, which are influenced to different degrees by human activities.
Modeling approaches are useful to simulate the behavior of whole...

Uses Computational Tools to Simulate Endocrine Disruption Phenomena

Endocrine Disruption Modeling provides a practical overview of the current approaches for modeling endocrine activity and the related potential adverse effects they may induce on environmental and human health. Based on the extensive research of an international panel of contributors from industry, academia, and regulatory agencies, this is the first book devoted to using computer tools to better understand and simulate the multifaceted aspects of endocrine disruption in humans and...

This book provides an up-to-date overview of research being done in the field of spatial data quality, which looks at understanding, measuring, describing, and communicating information about the imperfections of geographic data used by GIS and other mapping software. It presents results from a number of current research projects in this area, from the assessment of data accuracy to legal aspects relating to the quality of geographic information. The international contributors focus on the relationship between the quality of geographic data and the quality of decisions based on such data.

Juvenile hormones (JHs) are a group of structurally related sesquiterpenes secreted by the insect corpora allata. They affect most insect life-cycle stages and physiological functions, including embryogenesis, larval and adult development, metamorphosis, reproduction, metabolism, diapause, polyethism, and migration. Juvenoids such as methoprene, hydroprene, kinoprene, pyriproxyfen, and fenoxycarb are man-made chemicals that mimic the structure and/or activity of JHs, selectively targeting and disrupting the endocrine system of insects. They are particularly suited as larvicides for...

After their adventures in New York City, identical twins Payton and Emma Mills thought life would go back to normal. But when the girls are asked to star in a Teen Sheen shampoo commercial, they can't resist--especially because the shoot is in Hollywood
Suddenly life isn't so normal, especially when it involves Ashlynn (Payton's camp nemesis), a supercute heartthrob singer, and a cutthroat movie star wannabe.
When a mix-up at the commercial threatens to shut down production, can Payton, Emma, and...

Emma and Payton are home from Hollywood, but the drama continues: Not only is the Homecoming Dance coming up fast, but there's someone new in school Three someones, actually: triplets. Oliver, Dexter, and Asher look exactly the same, dress exactly the same, and--worse--have exactly the same superior attitude.

When the triplets mention they're participating in a regional Twins & SuperTwins Festival that has a Tweens Division and twin-related contests, Payton and...
