To establish effective locations and sizes of potential protected areas for reef ecosystems, detailed information about source and sink relationships between populations is critical, especially in archipelagic regions. Therefore, we assessed population structure and genetic diversity of Acropora tenuis, one of the dominant stony coral species in the Pacific, using 13 microsatellite markers to i...

The Afrotropic subgenus Deranchylaeus; of the colletid bee genus Hylaeus is revised for the first time on the basis of all the available type material. Here, 28 new synonymies were detected: Prosopis flaviscutum Alfken and Hylaeus graaffi Cockerell = H. curvicarinatus (Cameron); H. microstictus Cockerell = dregei (Strand); H. bequaertianus Bridwell and H. ogilviei Cockerell = H. gabonicus (Vach...

Heterotrophic feeding in newly-settled coral planulae can potentially improve survivorship and accelerate early development in some species; however, an optimal diet to facilitate this does not currently exist. This study evaluated the efficacy of three heterotrophic feeding regimes (enriched rotifers, unfiltered seawater, and a novel, particulate diet), against a wholly-phototrophic treatment ...

The reliability of different egg counting methods for estimating the intensity of Trichostrongylus tenuis infections in red grouse, Lagopus lagopus scoticus, was investigated in the autumn, when grouse may harbour high parasite intensities. Possible limitations to the use of these methods were also examined. Faecal egg counts were found to accurately estimate T. tenuis worm intensities, at leas...

Twenty species of Pselaphinae are newly recorded from New Brunswick, Canada. This brings the total number of species known from the province to 36. Thirteen of these species are newly recorded for the Maritime provinces of Canada. Dalmosella tenuis Casey and Brachygluta luniger (LeConte) are newly recorded for Canada. Collection and habitat data are presented for these species.

The aim of this note is to record the occurrence of the copepod Cyclopoida Thermocyclops tenuis in the Pantanal region, Central West of Brazil. The sampling was carried out in September, 2008, in a small artificial pond with an area of 22 m and 0.5 m deep, located in the city of Corumbá, MS, at 19° 00” 02’ S and 57° 37” 50’ W. The material was concentrated in a plankton net with 68 μm mesh size...

Hylastes spp. (Coleoptera: Scolytidae) were evaluated as potential vectors of Leptographium spp. fungi. Bark beetles were trapped from stands ofloblolly pine, Pinus taeda L., exhibiting a range of decline symptoms in central Alabama. Under controlled conditions, field-collected adult Hylastes salebrosus Eichoff (Coleoptera: Scolytidae) and Hylastes tenuis Eichoff (Coleoptera: Scolytidae), which...

Caste polyethism has been recorded in some termite species, however the foraging behavior of subterranean termites remains poorly known. Heterotermes tenuis Hagen (Isoptera: Rhinotermitidae) is a subterranean termite that is native to Brazil and is an agricultural and urban pest. The aim of this study was to investigate which caste acts as scouts when searching for food sources and determinate ...
