Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

open access: yesTAXON, EarlyView.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

The Pollen Collected by Bumble-Bees

open access: yesThe Journal of Animal Ecology, 1951
This study was carried out in western Scotland (Dunbartonshire) where the Bombidae, though numerous, are represented by few species. Bombus lucorum L., B. agrorum Fabricius, B. hortorum L. and B. pratorum L. are all common, the first being perhaps the most abundant. Only two other species, B. terrestris L. and B.

Pollination‐related plant traits under environmental changes: Seasonal and daily mismatches produce temporal constraints

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollination is a key tenet of ecosystem sustainability and food security, but it is threatened by climate change. While many studies investigated the response of plant‐pollination traits to temperature, few attempted multifactorial and integrative approaches with ...

Effect of temperature on the bioactive properties of bee pollen [PDF]

open access: yes, 2013
Bee pollen is flower pollen collected by the honey bee, Apis mellifera, for the purpose of feeding its larvae in the early stages of development.

Moisture source and diet affect development and reproduction of Orius thripoborus and Orius naivashae, two predatory anthocorids from southern Africa [PDF]

open access: yes, 2012
The effect of moisture source and diet on the development and reproduction of the pirate bugs, Orius thripoborus (Hesse) and Orius naivashae (Poppius) (Hemiptera: Anthocoridae) was examined in the laboratory. Both species had been collected in and around

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

Gradual pollen release in a buzz‐pollinated plant: Investigating pollen presentation theory under bee visitation

open access: yesFunctional 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,

The effects of methyl parathion on the colony dynamics of Apis mellifera : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Science in Ecology at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2000
The detrimental effects of pesticides to honey bee colonies were assessed using a combination of electronic and manual sampling techniques. Initial experiments determined that electronic bee counters could be used to identify and monitor toxic events ...

Separate and synergistic anti‐herbivore effects of non‐glandular trichomes and leaf chemistry in a desert plant

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant defence phenotypes commonly integrate physical and chemical traits that may act synergistically against herbivores, but empirical evidence for synergy as a defence strategy remains limited.
