Optimization of Wind‐PV Co‐Generation Systems Using Artificial Bee Colony and Back‐to‐Back Voltage Source Converter

open access: yesIET Smart Energy Systems, EarlyView.
The Graphical Abstract depicts the proposed Artificial Bee Colony algorithm‐based optimal tuning of PI controllers for back‐to‐back Voltage Source Converters in a hybrid wind–PV system. ABSTRACT This paper proposes a hybrid model‐based back‐to‐back voltage‐source converter (B2B‐VSC) system comprising a Photovoltaic (PV) array and a Permanent Magnet ...

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Sex Determination in the Honeybee [PDF]

open access: yesCell, 2003
Sex determination in honeybees involves a multi-allelic locus, such that homozygotes develop as males and heterozygotes as females. In this issue of Cell, report the cloning of the sex-determining gene, csd. It codes for an SR protein, and different alleles have very different amino-acid sequences. Inactivating csd leads to development as a male.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect 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.

The defence of the honeybee community [PDF]

open access: yesProceedings of the Royal Society of London. Series B - Biological Sciences, 1954
Abstract Pairs of colonies of differently coloured bees were placed with their entrances only 2 in. apart, and m any bees tried to enter the wrong colony, as if it were their own. Strangers were recognized by their different scent, and their reception depended upon foraging conditions.

Spatial and seasonal patterns of potential orchard pollinators across a Lake Ontario gradient

open access: yesAgricultural and Forest Entomology, EarlyView.
Potential pollinator captures varied by season, trap height and distance from Lake Ontario, indicating that flower visitors were not evenly distributed during apple bloom. Several common bee genera, including Lasioglossum, Agapostemon, Andrena and Apis, overlapped more closely with apple bloom than the dominant retained fly genus, Toxomerus.
