Back from the Brink is based on material presented at a conference held by the Commonwealth Endangered Species Advisory Committee in Sydney in December, 1995. The purpose of the conference was to bring together practitioners with a wide range of "hands-on" recovery planning and implementation experience to review and refine the recovery process for threatened species and ecological communities. A foreword by Dr Andrew Burbidge (Endangered Species Advisory Committee) addresses the need for community involvement and government co-operation, and highlights the importance of the recovery process itself, if conservation of threatened species and ecological communities is to be successful.

This comprehensive textbook provides a modern, self-contained treatment for upper undergraduate and graduate level students. It emphasizes the links between structure, defects, bonding, and properties throughout, and provides an integrated treatment of a wide range of materials, including crystalline, amorphous, organic and nano- materials. Boxes on synthesis methods, characterization tools, and technological applications distil specific examples and support student understanding of materials and their design. The first six chapters cover the fundamentals of extended solids, while later chapters explore a specific property or class of material, building a coherent framework for students to master core concepts with confidence, and for instructors to easily tailor the coverage to fit their own single semester course. With mathematical details given only where they strengthen understanding, 400 original figures and over 330 problems for hands-on learning, this accessible textbook is ideal for courses in chemistry and materials science.

This chapter reviews the study of cooperative behavior between species, with emphasis on examples of cooperative hunting found in a wide range of species. Seen in this context, the idea of cooperative hunting between humans and wolves that evolved into present relationships with dogs does not seem unusual or surprising. The chapter then critiques the proposal that competition between species is more important than cooperation in structuring ecological communities, discussing how this notion leads to a suite of ideas philosophically separating humans from the rest of the natural world. In many ways Western science is unintentionally complicit in such thinking. The chapter concludes by discussing complex cooperation, including long-term relationships between members of different species.

Collecting of Carabidae was conducted using pitfall traps at four sites. The first two sites (T1 + T2) were at the slope of Macošská stráň and the other two sites (T3 + T4) at the slope of Vilémovická stráň. The study was done in 2008 and 2009. At Macošská stráň in 2008, 21 species of Carabidae with the total number of 228 individuals were found and in 2009, 18 species of the total number of 116 specimens were collected. At Vilémovická stráň in 2008, 22 species of Carabidae with the total number of 1977 specimens were found and in 2009, 21 species of the total number of 623 specimens were caught. In terms of classification of relictness, Macošská stráň in 2008 was dominated by species of adaptable group A (60%), species of eurytop group (E) were represented by 35% and of relic group (R) by 5%. In 2009, the same representation of species of groups A and E (47%) were found and the species of group R were represented by 6%. Vilémovická stráň in 2008 was dominated by species of group A (52%), species of group E were represented by 43% and of group R by 5%. In 2009 also dominated species of group A (54%), species of group E were represented by 41% and of group R by 5%. In the studied area we reported four endangered species of Carabidae protected by Law (No. 395/1992 Coll.) as amended, these were Calosoma auropunctatum (critically endangered), Brachinus crepitans, Carabus ullrichii and Cicindela campestris (endangered) and two species listed under the Red List of Threatened Species of the Czech Republic (Veselý et al., 2005). One of the species is listed as vulnerable (Calosoma auropunctatum) and one as near endangered (Carabus cancellatus). Another significant species found on the monitored sites was Aptinus bombarda.

<p>ESA's Swarm mission continues to deliver excellent data providing insight into a wide range of geophysical phenomena. The mission is an important asset whose data are used within a number of critical resources, from geomagnetic field models to space weather services. As the product portfolio grows to better deliver on the mission's scientific goals, we face increasing complexity in accessing, processing, and visualising the data and models. ESA provides “VirES for Swarm” [1] (developed by EOX IT Services) to help solve this problem. VirES is a web-based data retrieval and visualisation tool where the majority of Swarm products are available. VirES has a graphical interface but also a machine-to-machine interface (API) for programmable use (a Python client is provided). The VirES API also provides access to geomagnetic ground observatory data, as well as forwards evaluation of geomagnetic field models to give data-model residuals. The "Virtual Research Environment" (VRE) adds utility to VirES with a free cloud-based JupyterLab interface allowing scientists to immediately program their own analysis of Swarm products using the Python ecosystem. We are augmenting this with a suite of Jupyter notebooks and dashboards, each targeting a specific use case, and seek community involvement to grow this resource.</p><p>[1] https://vires.services</p>

ABSTRACT:We examine whether religion influences company decisions related to corporate community involvement (CCI). Employing a large US sample, we show that the CCI initiatives of a company are positively associated with the level of Christian religiosity present in the region within which that company’s headquarters is located. This association persists even after we control for a wide range of firm characteristics and after we subject our results to several econometric tests. These results support our religious morality hypothesis which holds that companies headquartered in regions with higher levels of Christian religiosity will engage in more CCI initiatives. We also find that while Catholic and mainline Protestant religiosity have a positive influence on firms’ CCI initiatives, evangelical Protestant religiosity does not. This supports our differentiated responses hypothesis which holds that institutional differences among religious groups will produce different effects on companies’ CCI. This hypothesis is based on institutional theory.

In global trade analyses, plants are neglected in comparison to animals. Controlling and monitoring international trade in threatened species contributes to their overall conservation. Here, an in-depth look at the dynamics of the international trade in attractive and widely traded carnivorous Old World pitcher plants (Nepenthes spp.) from their first appearance in the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES) Trade Database in 1983 until 2017 is presented. The current trade of Nepenthes is rapidly growing in terms of the total volume traded and the number of both species and importing countries. Most of pitcher plants are globally traded as artificially propagated live plants. The share of wild-originated live plants was only 0.09%. Hybrids and Nepenthes spp. dominated the trade, representing 61 and 15% of the total traded volume respectively, followed by N. alata and N. mirabilis. The latter species was also the most traded species from the wild. Sri Lanka is a hotspot, exporting the highest volume and number of species of live pitcher plants. Monitoring of the trade is complicated by (1) the absence of a permit obligation for seeds, seedlings and in vitro cultures, and (2) the outdated list of valid species in the CITES Checklist. Using a holistic approach with a focus on the permanent monitoring, recording and assessing of international trade is desirable.
