Effects of habitat composition and landscape structure on worker foraging distances of five bumblebee species [PDF]

Ecological Applications, 2016
Bumblebees (Bombus spp.) are important pollinators of both crops and wild flowers. Their contribution to this essential ecosystem service has been threatened over recent decades by changes in land use, which have led to declines in their populations.

Field Activity of Reticulitermes grassei (Isoptera: Rhinotermitidae) in Oak Forests of the Southern Iberian Peninsula

Sociobiology, 2014
This paper presents preliminary data on the field activity of Reticulitermes grassei Clément in oak forests of the southern Iberian Peninsula. Recent research has provided information on the nature and intensity of termite damage to cork oaks (Quercus ...

Shortening day length as a previously unrecognized selective pressure for early breeding in a bird with long parental care [PDF]

, 2014
Several different selective pressures have been suggested to explain an intense competition for early return to breeding grounds in birds. In this study we hypothesized that shortening day length during summer months may constitute additional ...

Foraging under conditions of short-term exploitative competition: The case of stock traders [PDF]

, 2013
Theory purports that animal foraging choices evolve to maximize returns, such as net energy intake. Empirical research in both human and nonhuman animals reveals that individuals often attend to the foraging choices of their competitors while making ...

Late Winter Foraging by Honeybees (Hymenoptera: Apidae) at Sapsucker Drill Holes [PDF]

, 2017
Observations of Apis mellifera foraging at sapsucker drill holes were made during February 1988 in southwestern Virginia. Foraging bouts were dependent upon temperature; more bees visited drill holes when ambient temperatures exceeded 10oC. Honeybees did

Does foraging efficiency vary with colony size in the fairy martin Petrochelidon ariel? [PDF]

, 2009
Colonial breeding occurs in a wide range of taxa, however the advantages promoting its evolution and maintenance remain poorly understood. In many avian species, breeding colonies vary by several orders of magnitude and one approach to investigating the ...

Mucin glycan foraging in the human gut microbiome

Frontiers in Genetics, 2015
The availability of host and dietary carbohydrates in the gastrointestinal (GI) tract plays a key role in shaping the structure-function of the microbiota. In particular, some gut bacteria have the ability to forage on glycans provided by the mucus layer

Sensitivity to Sunk Costs Depends on Attention to the Delay

Frontiers in Psychology, 2021
In the WebSurf task, humans forage for videos paying costs in terms of wait times on a time-limited task. A variant of the task in which demands during the wait time were manipulated revealed the role of attention in susceptibility to sunk costs ...
