Local biodiversity change reflects interactions among changing abundance, evenness, and richness
Abstract Biodiversity metrics often integrate data on the presence and abundance of multiple species. Yet our understanding of covariation between changes to the numbers of individuals, the evenness of species relative abundances, and the total number of species remains limited.

Effect of storage time and type of packaging on seed quality of tall fescue [PDF]
After harvesting, the seed dormancy of grasses occurs. During the maturing period, seed dormancy is slowly reduced, and seed germination reaches the maximum values of use. Germination decreases during longer storage.

Calobota sericea is being evaluated as a forage for drought stressed areas. The nutritional quality of C. sericea from native populations are poor, and this is believed to be due to poor soil fertility.

Global bounded solution of the higher-dimensional forager-exploiter model with/without growth sources [PDF]
We investigate the higher-dimensional forager-exploiter model with homogeneous Neumann boundary condition. The existence and uniqueness of global bounded classical solution is established for the high dimension.

Abstract Diet is one of a limited set of key ecological parameters defining primate species. A detailed understanding of dental functional correlates with primate diet is a key component for accurate dietary inference in fossil primates. Although considerable effort has been devoted to understanding post‐canine dental function, incisor function remains

Comparative Winterhardiness of Cultivated and Native Alaskan Grasses, and Forage Yield and Quality as Influenced by Harvest Schedules and Frequencies, and Rates of Applied Nitrogen [PDF]
Objectives of this investigation were to compare certain traditional forage grasses with several native Alaskan grass species for forage yield, forage quality as measured by percent crude protein and digestibility (in vitro dry-matter disappearance ...

Morphology and function of pinniped necks: The long and short of it
Abstract Terrestrial vertebrates from at least 30 distinct lineages in both extinct and extant clades have returned to aquatic environments. With these transitions came numerous morphological adaptations to accommodate life in water. Relatively little attention has been paid to the cervical region when tracking this transition.
