Habitat Features, Coyotes, and Humans Drive Diel Activity Variation Among Sympatric Mammals
Integrative Zoology, EarlyView.We found that multiple mammal species show considerable variation in diel activity in response to several factors, with biotic variables (habitat features and the presence of coyotes Canis latrans) having the strongest overall effects. Our results have important implications for trophic dynamics. Future studies will need to account for these underlying

Host Phylogeny and Feeding Habit Jointly Govern Mammalian Gut Microbiota Composition
Integrative Zoology, EarlyView.Herbivores showed higher alpha diversity than carnivores/omnivores, while omnivores had the highest beta diversity. Host phylogeny influenced gut microbiota more strongly in herbivores/omnivores, with phylogenetic distance correlating to microbiota dissimilarity.

Supplementing beef cattle diets with brown seaweed affects coprophagous beetles' dung use
Agricultural and Forest Entomology, EarlyView.Supplementing beef cattle diets with brown seaweed reduced the attractiveness of dung for a common dung beetle (Onthophagus nuchicornis). Dietary supplementation with brown seaweed appeared to reduce the proportion of major males in the F1 generation.

Archaeometry, EarlyView.ABSTRACT Geochemical data compiled from dried sediments from three water reservoirs at the ancient Maya city of Ucanal, Petén, Guatemala, reveal low to undetectable fecal biomarker concentrations. These low concentrations may be the result of the aerobic decay of sterols combined with well‐managed waste disposal practices.

Food System Education Among High School Students [PDF]
, 2016 As the American public school system is currently designed, the average student is likely to graduate high school without ever having received any formal instruction regarding the food system in which he or she takes part as a consumer.

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Conservation Biology, EarlyView.Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Conservation Biology, EarlyView.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.
