MerF is a mercury transport protein: different structures but a common mechanism for mercuric ion transporters?
TLDR
It is shown that the merF gene from plasmid pMER327/419 encodes a 8.7 kDa mercury transport protein, by determining in vivo mercury volatilisation when MerF is expressed in the presence of mercuric reductase. Expand
Settlement-competency periods of larvae of three species of scleractinian corals
TLDR
Medium to long-distance larval dispersal of the species studied provides a mechanism for their widespread distribution in subtropical regions, on reefs which are often widely spaced and relatively isolated. Expand
Cell wall accessibility and cell structure limitations to microbial digestion of forage
TLDR
The anatomical limitations to digestion of thick-walled fiber particles in grasses were examined and suggested that an accumulation of toxic levels of phenolic monomers in cell lumens and at the digesting surface is unlikely, but more slowly diffusing phenolic-carbohydrate complexes could reach concentrations toxic to bacteria. Expand
Structural and chemical changes of cell wall types during stem development: consequences for fibre degradation by rumen microflora
TLDR
Analysis of tissue and cell architecture in grasses strongly supports the hypothesis that observed poor digestion of lignifled SW in vivo is due to limits imposed by anatomical structure. Expand
Adaptation to water stress of the leaf water relations of four tropical forage species.
TLDR
Water stress appeared to increase slightly the proportion of bound water (B) and the bulk modulus of elasticity (e) of the grass leaves, but it did not alter the relative water content at zero turgor (RWC0) or the ratio of turgid water content to dry weight of the tissue. Expand
Spawning patterns of scleractinian corals at the Solitary Islands: a high latitude coral community in eastern Australia
TLDR
The delay in the timing of coral spawn- ing at the Solitary Islands compared with the GBR coincides with the delayed rise in sea temperatures in the subtropics, which may account for the less synchronous pattern of reproduction in this high-latitude coral community. Expand
The pathway of arginine catabolism in Giardia intestinalis.
TLDR
There is no direct metabolic interface between arginine and glucose catabolism in Giardia intestinalis, and the activities of these enzymes are up to 250 fold greater than those reported for the enzymes in Trichomonas vaginalis. Expand
Migration ecology and morphometries of two Bar-tailed Godwit populations in Australia
TLDR
Using measurements of bill, wing, tarsus and total-head, it is shown that birds from the two main Australian non-breeding regions belong to separate populations, and that on northward migration, L. l. Expand
