Corticosterone and foraging behaviour in a pelagic seabird [PDF]

open access: yes, 2007
Because endocrine mechanisms are thought to mediate behavioral responses to changes in the environment, examining these mechanisms is essential for understanding how long-lived seabirds adjust their foraging decisions to contrasting environmental ...

Association patterns and foraging behaviour in natural and artificial guppy shoals [PDF]

open access: yes, 2008
Animal groups are often nonrandom assemblages of individuals that tend to be assorted by factors such as sex, body size, relatedness and familiarity.

The development of foraging organization

open access: yesAttention, Perception, & Psychophysics, 2021
In foraging tasks multiple targets must be found within a single display. The targets can be of one or more types, typically surrounded by numerous distractors. Visual attention has traditionally been studied with single target search tasks but adding more targets to the search display results in several additional measures of interest, such as how ...

Onset of morning activity in bumblebee foragers under natural low light conditions

open access: yesEcology and Evolution, 2021
Foraging on flowers in low light at dusk and dawn comes at an additional cost for insect pollinators with diurnal vision. Nevertheless, some species are known to be frequently active at these times.

Foraging innovation in the guppy [PDF]

open access: yesAnimal Behaviour, 1999
When novel behaviour patterns spread through animal populations, typically one animal will initiate the diffusion. It is not known whether such 'innovators' are particularly creative individuals, individuals exposed to the appropriate environmental contingencies, or individuals in a particular motivational state.

Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa

open access: yesAdvanced Science, EarlyView.
Sesbania, a leguminous halophyte, thrives in saline soils. Comparative genomics reveals key genomic variations—particularly chromosomal inversions—are identified as contributors to population differentiation and salt resilience. These findings advance the understanding of genomic variation driving evolution and phenotypic differentiation and offer ...

Development and Breeding of Herbicide‐Resistant Sorghum for Effective Cereal‐Legume Intercropping

open access: yesAdvanced Science, EarlyView.
This study identified two SbALS mutations (A93T and S624N) conferring robust herbicide resistance in sorghum, facilitating efficient weed control. Structural analysis revealed that imazamox resistance is mediated by disrupted herbicide binding. Furthermore, 126 imazamox resistant soybean varieties are screened for sorghum‐soybean intercropping ...
