How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Scientific societies serve as communities of practice in which scientists develop many of the skills and connections required for the progression of their careers. For example, scientific societies offer their members opportunities to attend career development programs, gain experience in communicating science, and receive recognition for achieveme...

Students sometimes struggle to organize complex concepts and visualize the connectedness of hierarchical groups, yet much of the biological sciences depends on ranking, ordering, or grouping of information. Diagnosing disease, converting units, and evolutionary relationships all follow stepwise ranking of groups of information. This article present...
Many studies have measured gastropod shell strength to investigate abiotic interactions and responses to predation. Shells are often preserved before strength is measured, but preservation may affect shell biomechanics, potentially influencing the outcome of these studies. We hypothesized that commonly used preservation methods (ethanol, freezing,...
Conventionally-grown and organically-grown tomato seeds sourced from both fresh tomatoes and store-bought packages were germinated for seven days to evaluate the effect of seed source on germination rates. Seeds from fresh Roma tomatoes were prepared by allowing them to ferment in their own pulp for 24 hours, while commercially packaged dry seeds d...
Evolution is a fundamental principle in biology, yet students, teachers, and the
public at large all too often misunderstand the way it works. I introduce a
hands-on exercise that emphasizes tree-thinking and phylogenies to organize
biodiversity. During the activity, students observe and investigate the patterns
and processes of macroevolution by f...
A description of a novel method for evaluating student performance
Ecological speciation studies have more thoroughly addressed premating than postmating reproductive isolation. This study examines multiple postmating barriers between host forms of Neochlamisus bebbianae leaf beetles that specialize on Acer and Salix trees. We demonstrate cryptic isolation and reduced hybrid fitness via controlled matings of these...
Animals create a wide variety of structures to deal with abiotic and biotic challenges. We evaluated an intriguing structure whose function has never been thoroughly tested. Specifically, we evaluated the hypothesis that the body-enclosing ‘faecal case’ created and lived in by the immature stages of Neochlamisus leaf beetles reduces their risk of p...
Leaf beetle taxa belonging to the Camptosomata use their fecal material to construct cases within which their larvae develop. Despite this intriguing behavior, the fine-scale natural history of very few camptosomates has been determined. Here, we present a highly detailed account of fecal case construction and associated behaviors and life history...
Constructions composed of faeces are rare in insects, but occur in certain leaf-beetle clades. Members of the subfamily Cryptocephalinae share a complex behavioural and morphological synapomorphy, involving portable faecal cases that house the immature stages. A maternally initiated egg case is expanded and enlarged through four larval stadia, then...
