Genomic responses to increased temperature and pollinator selection in Brassica rapa L.

open access: yesNew Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

Reproductive Ecology of Loeselia mexicana (Polemoniaceae): Protandry, Self-Incompatibility and a Generalized Pollination System Challenge Traditional Ornithophilous Assumptions

open access: yesEcologies
Loeselia mexicana (Polemoniaceae) is a Mexican shrub with significant medicinal value since pre-Hispanic times. Despite its ethnobotanical importance and apparent role in supporting pollinator communities, detailed information about its reproductive ...

Recent Insights Into Alzheimer's Disease: Advances in Pathophysiology and Therapeutic Strategies

open access: yesBrain Health, Volume 1, Issue 1, 26 March 2026.
ABSTRACT Alzheimer's disease (AD) is a complex neurodegenerative disorder driven by interplay among amyloid‐β (Aβ) plaques, tau neurofibrillary tangles, inflammation and comorbid pathologies. Recent advances in biomarkers and therapeutic approvals have reshaped our understanding of its pathophysiology and treatment landscape.

Migratory Status Shapes Exploratory Behavior but Not Learning Performance in Hummingbird Color Discrimination

open access: yesBirds
Behavioral flexibility allows animals to adjust their behavior in response to environmental changes. Hummingbirds, with their tetrachromatic color vision and enlarged hippocampal formation, represent an excellent model for studying cognitive flexibility ...

On the Origin of Risk Sensitivity: the Energy Budget Rule Revisited

open access: yes, 2015
The risk-sensitive foraging theory formulated in terms of the (daily) energy budget rule has been influential in behavioural ecology as well as other disciplines.

Fall Field Report, August–November 2015 [PDF]

open access: yes, 2015
To start, a housekeeping item: in the species accounts that follow, whenever I use the term migrant I am referring to fall migration only. Many species, of course, have differing migration strategies and timing in spring and fall. Much of the data used

Territorial Defense against Hummingbirds and Insects by Tropical Hummingbirds

open access: yesThe Condor, 1978
problems of observing them at close range and the variability of their behavior. Territorial hummingbirds are ideally suited for the study of time and energy budgets for the following reasons. (1) Their daily activities are usually quite localized. (2) They are not affected by the presence of a quiet observer and consequently can be observed at close ...

Colour for behavioural success [PDF]

open access: yes, 2018
Colour information not only helps sustain the survival of animal species by guiding sexual selection and foraging behaviour but also is an important factor in the cultural and technological development of our own species.

Influence of Normal Daytime Fat Deposition on Laboratory Measurements of Torpor Use in Territorial versus Nonterritorial Hummingbirds

open access: yes, 2003
Fat deposition and torpor use in hummingbirds exhibiting distinct foraging styles should vary. We predicted that dominant territorial hummingbirds will use torpor less than subordinate nonterritorial species because unrestricted access to energy by ...
