The Islands of East Melanesia have a unique and highly endemic frog fauna derived entirely from overseas colonisation events. Within New Britain is notable centre diversity endemism, with at least 15 species, mostly in the ceratobatrachid genus Cornufer . Here we describe first pelodryadid treefrog Britain. new species member Litoria thesaurensis group but can be distinguished near relatives by...

We conducted an experiment to quantify the accuracy of methods based on n-alkanes and long-chain fatty alcohols for determining the diet composition of animals grazing complex swards. We cut forage from two indigenous vegetation communities, a Molinia caerulea-dominated grassland and a Calluna vulgaris-dominated dwarf-shrub community, and offered it to mature ewes in different ratios in a zero-...

The significance of mucus trails derived from the herbivorous gastropods Patella caerulea, Monodonta turbinata and Tegula sp. in enhancing microbial activity in marine rocky intertidal and sublittoral zones was investigated by means of microcosm and field experiments. A pronounced increase of bacterial abundance concurrently with extracellular glucosidase activity (alpha-Dand betaD-glucosidase)...

In blue petrels (Halobaena caerulea), females are supposed to be particularly choosy and mate choice can take a couple of years. these lifelong monogamous seabirds, choosing good is crucial has strong influence on their fitness. Due nocturnal habits, the absence sexual dimorphism, physical barrier between males calling from burrow flying above colony, vocal signals seem one main channels for co...
