Spatio-temporal Functional Regression on Paleo-ecological Data [PDF]
, 2008 The influence of climate on biodiversity is an important ecological question. Various theories try to link climate change to allelic richness and therefore to predict the impact of global warming on genetic diversity.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant chemistry mediates interactions between plants and their environment. While intraspecific chemodiversity at the individual plant level is well studied, the effects of chemodiversity at the plant community level on arthropod interactions need more attention.

Royal Society Open ScienceAgricultural landscapes often provide an impoverished environment for bees given their limited plant and pollen diversity. Agri-environment schemes (AES) such as flower strips have been developed to improve the quality of the agricultural environment for

Some Carbohydrates Found in Pollen and Pollen Substitutes are Toxic To Honey Bees
The Journal of Nutrition, 1977 Carbohydrates in some pollen substitutes (galactose, lactose, raffinose, stachyose, glucuronic acid, galacturonic acid, polygalacturonic acid, and pectin) were toxic to caged adult Apis mellifera L. These toxins can be diluted to safe levels by sucrose.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The rate at which flowers dispense pollen across successive pollinator visits is a key functional trait influencing male reproductive success. Pollen presentation theory (PPT) predicts that when pollinators are abundant and actively groom their bodies to collect pollen,

Journal of Animal Ecology, EarlyView.This study identifies pollen from over 100 plant species—including wildflowers, food and crops—carried by hoverflies alighting onto an oilrig 200 km off the coast during seasonal migrations. Analysis of their movements indicates a huge potential to enhance long distance gene flow between plants and increase pollination services.

Complex effects of climatic variation on bumblebee queen fitness
Journal of Animal Ecology, EarlyView.A dearth of data on the health of wild‐insect populations hinders efforts to fully grasp the extent of historical population declines or unravel the mechanisms driving these effects. We help fill this data deficit by testing how climatic variation affects health, reproduction, size and survival in bumblebees—important insect pollinators.
