Subterranean termites in the genus Heterotermes Froggatt (Rhinotermitidae: Heterotermitinae) are pantropical wood feeders capable of causing significant structural damage. The aim of this study was to investigate soldier morphological attributes in three Puerto Rican species of Heterotermes previously identified by sequencing of two mitochondrial genes and attributed to Heterotermes tenuis (Hag...

BACKGROUND The preference for a fairer skin-tone has become a common trend among both men and women around the world. In this study, seaweeds Sargassum polycystum and Padina tenuis were investigated for their in vitro and in vivo potentials in working as skin whitening agents. Seaweed has been used as a revolutionary skin repairing agent in both traditional and modern preparations. The high ant...

The fungus Alternaria tenuis normally produces tenuazonic acid (3-acetyl-5-secbutyltetramic acid). On supplementation of the culture substrate with l-valine and l-leucine, the organism formed two new tetramic acids, 3-acetyl-5-isopropyltetramic acid and 3-acetyl-5-isobutyltetramic acid, respectively. l-Phenylalanine was not utilized by the organism as a tetramic acid precursor.

This report describes a unique case of presumed migration of Parelaphastrongylus tenuis through the spinal cord into the eye of a llama where it survived and matured within the ocular environment. Blindness of the eye was most likely attributable to migration of the parasite through the central nervous tissue.

The meningeal worm (Parelaphostrongylus tenuis) is a nematode parasite that commonly infects white-tailed deer (Odocoileus virginianus; WTD) throughout the deciduous forest biome and deciduous-coniferous ecotone of eastern and central North America; the species is not known to occur west of the grassland biome of central North America. We used county-specific prevalence data to evaluate potenti...

The genus Liolaemus is one of the most ecologically diverse and species-rich genera of lizards worldwide. It currently includes more than 250 recognized species, which have been subject to many ecological and evolutionary studies. Nevertheless, Liolaemus lizards have a complex taxonomic history, mainly due to the incongruence between morphological and genetic data, incomplete taxon sampling, in...

New Zealand Journal of Ecology (1997) 21(2): 121-128 ©New Zealand Ecological Society E. wiltoni Locket, Leptyphanthes tenuis (Blackwall) dominated in pitfall trap catches. In this paper, we provide the first quantitative data on the density and diversity of spiders in New Zealand cultivated land under different management regimes, and compare the species assemblages with those found in similar ...

1. Among the commonest sexual signals of birds are the red-yellow traits pigmented by carotenoids, but how they reliably advertise individual quality remain poorly understood. Here we tested the hypothesis that carotenoid-based signalling is enhanced by testosterone but reduced by parasites, and that the dual action of testosterone on ornament expression and parasite resistance ensures reliable...

Abstract In recent years the quest for a circular economy approach and upcycling of secondary raw materials have been pushed in global political agenda. Increased interest has taken by recovery from sludges, brines, contaminated waters other media, all included larger umbrella identified as “low-grade” mineralisation. Contaminated soils an interesting role this process, various methodologies de...
