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

Optimally frugal foraging [PDF]
Physical Review E, 2018 We introduce the \emph{frugal foraging} model in which a forager performs a discrete-time random walk on a lattice, where each site initially contains $\mathcal{S}$ food units. The forager metabolizes one unit of food at each step and starves to death when it last ate $\mathcal{S}$ steps in the past. Whenever the forager decides to eat, it consumes all

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 ...

Birds, 2022 Shorebirds commonly exhibit cathemeral activity and commonly forage throughout a 24 h period. Conservation of endangered shorebirds should then extend to protection at night, yet little data exists on overall time budgets of such species at night.

Utilisation of intensive foraging zones by female Australian fur seals. [PDF]
, 2015 Within a heterogeneous environment, animals must efficiently locate and utilise foraging patches. One way animals can achieve this is by increasing residency times in areas where foraging success is highest (area-restricted search).

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 ...

Plant-associated CO2 mediates long-distance host location and foraging behaviour of a root herbivore
eLife, 2021 Insect herbivores use different cues to locate host plants. The importance of CO2 in this context is not well understood. We manipulated CO2 perception in western corn rootworm (WCR) larvae through RNAi and studied how CO2 perception impacts their ...

Information foraging with an oracle
PLOS ONE, 2023 During ecological decisions, such as when foraging for food or selecting a weekend activity, we often have to balance the costs and benefits of exploiting known options versus exploring novel ones. Here, we ask how individuals address such cost-benefit tradeoffs during tasks in which we can either explore by ourselves or seek external advice from an ...

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
