"Two mosquito species in America have been engaged in a battle for dominance for the past 30 years: the native Aedes aegypti and the invasive Aedes albopictus -- also known as the Asian tiger mosquito The tiger mosquito has a distinct competitive advantage Male Aedes albopictus are really good at wooing female Aedes aegypti The resultant interspecies mating permanently sterilizes the female, effectively ending her reproductive future But Aedes aegypti are evolving the ability to resist the advances of Aedes albopictus Although this is good news for Aedes aegypti the outlook is darker for humans, as Aedes aegypti are key transmitters of diseases like Zika and dengue fever Researchers have now started to uncover the genetic changes tied to this resistance Uncovering the molecular correlates governing mosquito mating preferences could lead to better control strategies and might help prevent future outbreaks of disease Burford Reiskind, et al..."

The study of biomimicry and sustainable design promises great benefits in design applications, offering cost-effective, resourceful, non-polluting avenues for new enterprise. An important final caveat for students to understand is that once copied, species are not expendable. Biomimicry is intended to help people by identifying natural functions from which to pattern human-driven services. Biomimicry was never intended to replace species. Ecosystems remain in critical need of ongoing protection and biodiversity must be preserved for the overall health of the planet. This activity addresses the negative ramifications of species decline. For example, pollinators such as bees are a vital work force in agriculture. They perform an irreplaceable task in ensuring the harvest of most fruit and vegetable crops. In the face of the unexplained colony collapse disorder, we are only now beginning to understand how invaluable these insects are in keeping food costs down and even making the existence of these foods possible for humans.

This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they learn about cladograms and the vast variety of dinosaurs that once roamed Earth. The activity opens by telling kids that there are more than 400 known species of extinct dinosaurs and by explaining how cladograms show their relationships to one another. Students then go to an interactive cladogram that has 19 dinosaur species. Each of the 19 dinosaurs includes a trading card with details about the species and its discovery, photographs, and interactive multiple-choice and "Fact or Fiction?" quizzes.

"HIV infection remains unacceptably common among women in sub-Saharan Africa. One possible contributing factor is the composition of the vaginal microbiota, as African, Caribbean and other Black (ACB) women have an increased rate of bacterial vaginosis (BV), which is associated with increased HIV risk. Targeting the vaginal microbiota and treating BV could help prevent HIV among women. In the absence of BV, the vaginal microbiota is predominated by one of several _Lactobacillus_ species that provide different levels of BV and HIV protection. _L. crispatus_ is associated with exclusion of BV-associated bacteria and reduced HIV risk while _L. iners_, the most common species among ACB women, seems less protective. The reduced protection provided by _L. iners_ is supported by genomic differences, such as the absence of a gene encoding an HIV-trapping D-lactate isomer and the presence of genes encoding pro-inflammatory cytotoxins..."

Global populations have for decades migrated more and more to coastal regions. This colonization of the coast has resulted in large areas of what was formerly rocky shores, salt marshes, and mudflats becoming built environment for people. What’s more, as sea levels rise more, coastal defenses are being put in place to protect towns and cities from the oceans. These coastal defenses are also replacing natural habitats that play a vital role in the life cycle of fish, including spawning locations, nurseries, and sources of planktonic food. This, in turn, is affecting the fish stocks in the oceans. During this lesson, students will gain a basic understanding of the idea that specific habitats are essential in the lifecycle of some species. Students will work through the engineering design process to build a ‘bio-block’ solution to make sea walls a more nature-friendly solution for flood protection.

There is life all around us! Look out a window, and we see a variety of living things. Even in the middle of a big city, plants grow in between cracks in the sidewalk. All that life is called Biodiversity. Check out the Natural Resources Intern video to learn how high school students are improving biodiversity on an Eastern Oregon ranch. Then, in the Discovery Challenge video, investigate biodiversity at two different sites by collecting data at each sites. With your data, you will be able to compare the biodiversity at the two sites.
This lesson introduces NGSS standards, and those standards are listed in the lesson and is part of the Explore Science Club series, an online Career Connected Learning program developed by the Greater Oregon STEM Hub. To learn more find us at: www.go-stem.org.

Short Description: The aim of this book is to build a bridge between conservation theory and practice. The narrative is focused specifically on Canada. This permits an integrated treatment, where conservation theory is presented in the context of the social and institutional framework responsible for its implementation. Special attention is given to topics that are the subject of debate or controversy, as they provide valuable insight into the practical aspects of conservation. The result is a comprehensive synthesis of applied biodiversity conservation, tailored to the needs of conservation students and practitioners in Canada.
Long Description: Conservation is often portrayed as an applied science—a body of knowledge about how ecological systems function, how they are threatened, and how they can be maintained. Conservation is also a form of management. It entails working with people to achieve desired ecological outcomes, grappling with conflicting land-use objectives, and making optimal use of available conservation resources. The aim of this book is to build a bridge between these two perspectives, linking theory with practice.
Major topic areas include the history of conservation, the social and scientific foundations of conservation, threats to biodiversity, applied conservation methods at both the species and ecosystem levels, the accommodation of climate change, and structured decision making. Special attention is given to topics that are the subject of debate or controversy, as they provide valuable insight into the practical aspects of conservation. The narrative is focused specifically on Canada. This permits an integrated treatment, where conservation theory is presented in the context of the social and institutional framework responsible for its implementation. The result is a comprehensive synthesis of applied conservation, tailored to the needs of conservation students and practitioners in Canada. Learning is supported by an engaging and clear writing style and 196 colour illustrations.
