Hotspots on cold mountains: Hot flowers as pollinator refuges in mountain ecosystems

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mountain environments constrain the activity of ectothermic insects. Yet, fine‐scale thermal refuges can buffer these thermal constraints, helping insects remain active in cold conditions.

Differences in the genetic structure of citrus triploid hybrids recovered from 2x X 2x and 4x X 2x sexual hybridizations [PDF]

, 2015
Citrus triploid hybrids can be recovered by 2x X 2x hybridisations as a consequence of the formation of 2n gametes or by interploid hybridisation. Most of the 4x parents used in our program are doubled-diploid (DD), also known as autotetraploid.

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Efficient haploid production on 'Wilking' mandarin by induced gynogenesis [PDF]

, 2015
Seedlessness is a major criterion for the citrus fresh fruit market. Therefore, triploid breeding appears very promising for the selection of new citrus cultivars.

Bee community assembly is regulated by functional traits in pristine tropical forest environments

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding the drivers of bee beta diversity across pristine environments in the Amazon is critical for ensuring biodiversity conservation, restoration, sustainable land use planning and economic development.

Insights on the nutritional ecology of a nocturnal pollinating insect

Insect Science, EarlyView.
Nutritional ecology examines the environmental effects on nutritional needs, food intake and foraging behaviors, and the use of nutrients ingested by animals. Among insects, Lepidoptera are often considered opportunistic foragers that visit a wide variety of available flowers, although with some preferences.

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

Insect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.
