The limitations of the methods of identifying the floral source of honeys [PDF]
, 1998 The pollen grains in honey reveal the types of plants that were around when the bees produced the honey, thus it is valid to use melissopalynology to determine the geographical origin of honeys, but there are several reasons why it is less valid for ...

Pollination by flies, bees, and beetles of Nuphar ozarkana and N. advena (Nymphaeaceae) [PDF]
, 2000 Nuphar comprises 13 species of aquatic perennials distributed in the temperate Northern Hemisphere. The European species N. lutea and N. pumila in Norway, the Netherlands, and Germany are pollinated by bees and flies, including apparent Nuphar ...

Plant protection product residues in plant pollen and nectar: A review of current knowledge
Environmental Research, 2020 Exposure to Plant Protection Products, PPPs, (fungicides, herbicides and insecticides) is a significant stressor for bees and other pollinators, and has recently been the focus of intensive debate and research. Specifically, exposure through contaminated pollen and nectar is considered pivotal, as it presents the highest risk of PPP exposure across all

Oikos, EarlyView.Droughts, increasingly frequent under human‐driven climate change, are expected to intensify globally. Both pulsed and prolonged droughts can strongly affect organismal survival and population dynamics, potentially altering terrestrial communities and ecosystems.

Area‐restricted search under realistic constraints
Oikos, EarlyView.Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

PLANTS, PEOPLE, PLANET, EarlyView.Understanding how climate change impacts the plant life cycle is critical for maintaining biodiversity and ecosystem services. Our findings suggest that Terminalia paniculata Roth, a common tropical deciduous tree species in the Western Ghats, is now flowering and fruiting at more scattered times than it used to in the past.

Salt intake and regulation in two passerine nectar drinkers: white-bellied sunbirds and New Holland honeyeaters [PDF]
, 2012 Avian nectarivores face the dilemma of having to conserve salts while consuming large volumes of a dilute, electrolyte-deficient diet. This study evaluates the responses to salt solutions and the regulation of salt intake in white-bellied sunbirds ...

PLANTS, PEOPLE, PLANET, EarlyView.Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...
