Test of theory of foraging mode: Goldcrests, Regulus regulus, forage by high‐yield, energy‐expensive hovering flight when food is abundant but use low‐yield, low‐cost methods when food is scarce

Ecology and Evolution, 2021
Here, I describe foraging behavior of goldcrests, Regulus regulus, based on eight years of field observation in a coniferous forest dominated by Norway spruce Picea abies in southwestern Sweden.

Feeding ecology of a highly aerial bird during its long breeding season

Avian Research, 2023
Pallid Swifts (Apus pallidus), as other swifts, are birds extremely adapted to an aerial lifestyle, showing unique adaptations that allow them to fly almost continuously.

The application of foraging theory to the information searching behaviour of general practitioners

BMC Family Practice, 2011
Background General Practitioners (GPs) employ strategies to identify and retrieve medical evidence for clinical decision making which take workload and time constraints into account.

How Plant Toxins Cause Early Larval Mortality in Herbivorous Insects: An Explanation by Modeling the Net Energy Curve

Toxins
Plants store chemical defenses that act as toxins against herbivores, such as toxic isothiocyanates (ITCs) in Brassica plants, hydrolyzed from glucosinolate (GLS) precursors.

Foraging behaviour of Brazilian riverine and coastal fishers: How much is explained by the optimal foraging theory?

Conservation & Society, 2011
Optimal Foraging Theory (OFT) is here applied to analyse the foraging behaviour of Brazilian artisanal fishers of the Atlantic coast (Itacuruçá and São Paulo Bagre villages) and of the inland Amazonian region (Jarauá and Ebenezer villages).

Creative foraging: An experimental paradigm for studying exploration and discovery. [PDF]

PLoS ONE, 2017
Creative exploration is central to science, art and cognitive development. However, research on creative exploration is limited by a lack of high-resolution automated paradigms.

Trail complexity and foraged plants for the leaf-cutting ant Atta sexdens (Hymenoptera: Formicidae) in a caatinga area of Bahia

Zoologia (Curitiba)
Leaf-cutting ants (LCAs; Atta, Acromyrmex, and Amoimyrmex) are key herbivores in Neotropical ecosystems, preferentially harvesting leaves from palatable plant species such as pioneers and colonizers.

Investigating Optimal Foraging Theory in the Laboratory

The American Biology Teacher, 2014
Optimal foraging theory is a principle that is often presented in the community ecology section of biology textbooks, but also can be demonstrated in the laboratory. We introduce a lab activity that uses an interactive strategy to teach high school and/or college students about this ecological concept.

Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

Advanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Iron‐Mediated Release of Aged Dissolved Organic Carbon From Waterlogged Peatland Under Warming

Advanced Science, EarlyView.
This study conducts a five‐year in situ warming experiment in high‐altitude peatlands to examine dissolved organic carbon (DOC) release. The study shows that warming promotes the release of plant‐derived modern DOC in drained peatlands, but amplifies aquatic export of century‐old DOC from waterlogged peatlands via Fe‐mediated DOC mobilization—a ...
