Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure
Oikos, EarlyView.Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

Combined nutritional stress and a new systemic pesticide (flupyradifurone, Sivanto®) reduce bee survival, food consumption, flight success, and thermoregulation. [PDF]
, 2019 Flupyradifurone (FPF, Sivanto®) is a new butenolide insecticide that, like the neonicotinoids, is a systemic nicotinic acetylcholine receptor (nAChR) agonist.

Oikos, EarlyView.The ability of plants to attract pollinators is context‐dependent, influenced by floral traits, abundance, and resources from the plant community. Indirect interactions through shared pollinators, from competition to facilitation, may lead to varied reproductive outputs in plants, and the mechanisms behind these interactions remain to be fully ...

Is there a diel pattern to nectar secretion in the Red Bloodwood Corymbia gummifera? [PDF]
, 2013 Nectar secretion was measured at 6-h intervals over a 24-h period in flowers of the Red Bloodwood, Corymbia gummifera (family Myrtaceae). Secretion varied among time periods and among trees. There was no clear diurnal or nocturnal pattern.

Botanical Sciences, 2013 El néctar de flores polinizadas por colibríes es usualmente robado por animales no polinizadores, por ello se esperaría que plantas sometidas al robo de néctar presenten distintas estrategias que permitan mitigar los costos asociados.

Ecology, 2016 AbstractSecondary metabolites that are present in floral nectar have been hypothesized to enhance specificity in plant–pollinator mutualism by reducing larceny by non‐pollinators, including microorganisms that colonize nectar. However, few studies have tested this hypothesis.

Oikos, EarlyView.Niche breadth, reflecting the range of environmental conditions or resources a species can exploit, influences its distribution, persistence, vulnerability to environmental change, and interspecific interactions. The elevational niche‐breadth hypothesis predicts broader ecological niches at higher elevations due to increased environmental stress and ...

Bumblebees gain fitness through learning [PDF]
, 2007 Despite the widespread assumption that the learning abilities of animals are adapted to the particular environments in which they operate, the quantitative effects of learning performance on fitness remain virtually unknown. Here we evaluate the learning
