Centuries of Anadromous Forage Fish Loss: Consequences for Ecosystem Connectivity and Productivity

open access: yes, 2012
Lost biomass of anadromous forage species resulting from the seventeenth to nineteenth century damming of waterways and from overharvest in the northeastern United States contributed to significant changes in coastal marine—terrestrial ecosystems ...

Hypercanines: Not just for sabertooths

open access: yesThe Anatomical Record, EarlyView.
Abstract Hypercanines are here defined as hypertrophied caniniform teeth, that is, canine teeth that are elongated to serve specific functions in different clades of mammals and their synapsid ancestors. This article presents an overview of the occurrence of hypercanines, their growth, and their function across a broad range of clades.

Predation thresholds for reintroduction of native avifauna following suppression of invasive Brown Treesnakes on Guam

open access: yesEcological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract The brown treesnake (BTS) (Boiga irregularis) invasion on Guåhan (in English, Guam) led to the extirpation of nearly all native forest birds. In recent years, methods have been developed to reduce BTS abundance on a landscape scale. To help assess the prospects for the successful reintroduction of native birds to Guåhan following BTS ...

Forage Brassica Variety Trial [PDF]

open access: yes, 2012
Forage brassicas can provide a near-concentrate type diet late in the season, allow for an extra grazing opportunity after annual row crops are harvested, and establish forage to fill a gap in feed quality and supply.

Disparity of turbinal bones in placental mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Insect assemblages and their preference for Lupinus albus and L. luteus

open access: yesIrish Journal of Agricultural and Food Research, 2018
While lupin has undergone extensive research to ascertain its suitability for growth as forage or grain legume crop, the present trend is for research to be centered on its applicability in the seed protein and oil industry.

Warm Season Annual Forage Performance Trials [PDF]

open access: yes, 2010
In 2010, the University of Vermont Extension continued their research to evaluate warm season annual forage systems. Warm season annual forages include grasses such as sorghum, sudangrass, sorghumsudangrass, Japanese millet, and pearl millet varieties ...

Group Foraging in Dynamic Environments [PDF]

open access: yesarXiv, 2012
Previous human foraging experiments have shown that human groups routinely undermatch environmental resources much like other animal species. In this experiment, we test whether humans also selectively rely on others as information sources when the environmental state is uncertain, and we also test whether overt signals of other foragers' success ...

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

open access: yesThe Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.
