Background
Professional development (PD) efforts have improved acceptance and pedagogical practice related to the theory of evolution in high school biology teachers. However, these teachers express need for more PD related to evolution. It therefore becomes necessary to understand teachers’ PD needs prior to structuring PD efforts.
Methods
We formulated and validated a model to explain secondary teachers’ PD needs using data from a survey of 276 secondary biology teachers who reported teaching evolution.
Results
In addition to reliable subscales, we found that obstacles to teaching evolution, school and community support for evolution instruction, confidence in evolution instruction, and prior …
Mechanisms Of Ash Resistance To Emerald Ash Borer: Progress And Gaps, Caterina Villari, Justin G.A. Whitehill, Don Cipollini, Daniel A. Herms, Pierluigi Bonello

The emerald ash borer (EAB) invasion of North America has caused widespread mortality of native ash, and is threatening the native ash resources. As a consequence of its devastating impact, EAB has caught the attention of the scientific community, and several studies have focused on different aspects of the biology and behavior of this pest, including its interaction with host defenses. Here we present a review of the published literature on mechanisms of ash resistance to EAB, the understanding of which, despite starting from a tabula rasa, has achieved significant progress in the last few years.

A Quantitative Analysis Of Kalandars And Captive Bears In Pakistan, Thomas P. Rooney, Kendra C. Millam
A Quantitative Analysis Of Kalandars And Captive Bears In Pakistan, Thomas P. Rooney, Kendra C. Millam

In 2013, the Bioresource Research Centre (Islamabad, Pakistan) conducted a comprehensive census of the remaining dancing and bear-baiting bears in Pakistan. This involved locating and counting the actual involved bears and bear keepers (kalandars), collecting detailed socio-economic data from the bear-keepers, and identifying attitudes and key drivers behind this livelihood. This report summarizes the findings from the census, reveals relationships in the data that are not immediately apparent, and identifies potential leverage points for ongoing campaign efforts.
White-Tailed Deer Are A Biotic Filter During Community Assembly, Reducing Species And Phylogenetic Diversity, Danielle R. Begley-Miller, Andrew L. Hipp, Bethany H. Brown, Marlene Hahn, Thomas P. Rooney

Community assembly entails a filtering process, where species found in a local community are those that can pass through environmental (abiotic) and biotic filters and successfully compete. Previous research has demonstrated the ability of white-tailed deer (Odocoileus virginianus) to reduce species diversity and favour browse-tolerant plant communities. In this study, we expand on our previous work by investigating deer as a possible biotic filter altering local plant community assembly. We used replicated 23-year-old deer exclosures to experimentally assess the effects of deer on species diversity (H′), richness (SR), phylogenetic community structure and phylogenetic diversity in paired …

The well-known regenerative abilities of planarian flatworms are attributed to a population of adult stem cells called neoblasts that proliferate and differentiate to produce all cell types. A characteristic feature of neoblasts is the presence of large cytoplasmic ribonucleoprotein granules named chromatoid bodies, the function of which has remained largely elusive. This study shows that histone mRNAs are a common component of chromatoid bodies. Our experiments also demonstrate that accumulation of histone mRNAs, which is typically restricted to the S phase of eukaryotic cells, is extended during the cell cycle of neoblasts. The planarian PIWI homologs SMEDWI-1 and SMEDWI-3 are …
