Social inhibition maintains adaptivity and consensus of foraging honeybee swarms in dynamic environments [PDF]
arXiv, 2019 To effectively forage in natural environments, organisms must adapt to changes in the quality and yield of food sources across multiple timescales. Individuals foraging in groups act based on both their private observations and the opinions of their neighbors. How do these information sources interact in changing environments?

Journal of Dairy Science, 2003 The Penn State Particle Separator has led to widespread measurement of forage and total mixed ration (TMR) particle size. However, a large proportion of small particles may pass through both sieves when a TMR is analyzed, and field research has suggested

Alfalfa seed processing on different equipment [PDF]
Journal on Processing and Energy in Agriculture, 2011 For the establishment and exploitation of alfalfa, the seed must be of high purity, germination, and high genetic value. Most of these requirements is realized through processing or removal of foreign matter and seeds of lower quality.

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas
American Journal of Botany, EarlyView.Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract Large, citizen‐science species databases are powerful resources for predictive species distribution modeling (SDM), yet they are often subject to sampling bias. Many methods have been proposed to correct for this, but there exists little consensus as to which is most effective, not least because the true value of model predictions is hard to ...

Inheritance of main quantitative traits in broad bean (Vicia faba L.)
Journal of BioScience and Biotechnology, 2019 The purpose of this study was to analyze the values of some genetic parameters of hybrid populations of Vicia faba, which would allow rational selection of desired genotypes in terms of main quantitative traits.

Forage Intercropping for Resiliency Experiment [PDF]
, 2017 Producing high quality forage crops is exceedingly challenging in Vermont as climate change progresses with more precipitation, faster rates of precipitation, and higher annual temperatures (Faulkner, 2014).

A continuous model of ant foraging with pheromones and trail formation [PDF]
arXiv, 2014 We propose and numerically analyze a PDE model of ant foraging behavior. Ant foraging is a prime example of individuals following simple behavioral rules based on local information producing complex, organized and ``intelligent'' strategies at the population level.

Functional diversity of farmland bees across rural–urban landscapes in a tropical megacity
Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract Urbanization poses a major threat to biodiversity and food security, as expanding cities, especially in the Global South, increasingly compete with natural and agricultural lands. However, the impact of urban expansion on agricultural biodiversity in tropical regions is overlooked.
