The Central Role of Dispersal in the Maintenance and Persistence of Seagrass Populations
TLDR
The role that sexual reproduction, pollen, and seed dispersal play in maintaining species distributions, genetic diversity, and connectivity among seagrass populations is explored and the relationship between long-distance dispersal, genetic connectivity, and the maintenance of genetic diversity is addressed. Expand
Back to the future: developing hypotheses on the effects of climate change on ovine parasitic gastroenteritis from historical data.
TLDR
Seasonal rates of diagnosis suggest that, in line with increases in temperature, fewer larvae of Teladorsagia and Trichostrongylus species survive the winter and spring at pasture, while the windows of transmission of these species, and of Haemonchus contortus, have extended into the autumn. Expand
Ultraviolet light increases mortality of nematode larvae and can explain patterns of larval availability at pasture.
TLDR
Increased mortality caused by UV irradiation could help to explain patterns of abundance of infective stages at pasture, especially pronounced population declines in spring when solar radiation rises rapidly and temperature is still low. Expand
The influence of temperature on the development, hatching and survival of Nematodirus battus larvae
TLDR
It is argued that the findings confirm the likelihood of an arctic origin of N. battus, an economically important and highly pathogenic parasite of sheep in the temperate regions, in terms of optimization of larval survival. Expand
SPATIAL AND TEMPORAL VARIABILITY IN BIOMASS AND PRODUCTION OF PSAMMOPHYTIC HALIMEDA INCRASSATA (BRYOPSIDALES, CHLOROPHYTA) IN A CARIBBEAN REEF LAGOON 1
Estimates for the production of calcium carbonate by Halimeda spp. have been based on limited measures in small areas or over short periods, subsequently extrapolated over larger temporal and spatialExpand
The influence of water on the migration of infective trichostrongyloid larvae onto grass
TLDR
Findings suggest continuing random movement of free larvae in parasitic nematodes from sheep dung onto grass, and in the context of trade-offs faced by the parasites. Expand
Hatching behaviour of Nematodirus filicollis in a flock co-infected with Nematodirus battus
SUMMARY The development and survival of larvae of Nematodirus filicollis, an important nematode parasite of ruminants, were extensively investigated in the laboratory for the first time, using eggsExpand
Selective Elimination of Rooted Plants from a Tropical Seagrass Bed in a Back-Reef Lagoon: A Hypothesis Tested by Hurricane Wilma (2005)
VAN TUSSENBROEK, B.I.; BARBA SANTOS, M.G.; VAN DIJK, J.K.; SANABRIA ALCARAZ, M.S.N., and TÉLLEZ CALDERÓN, M.L., 2008. Selective elimination of rooted plants from a tropical seagrass bed in aExpand
The influence of water and humidity on the hatching of Nematodirus battus eggs.
TLDR
Examination of the influence of water on the ecology of the eggs of Nematodirus battus finds that mass hatching of infective larvae, described at pasture when spells of rain follow periods of drought, is unlikely to occur as the result of a sudden water influx into eggs. Expand
Microsatellite markers in the Australian desert plant, Solanum centrale (Solanaceae).
TLDR
Six highly polymorphic co-dominant loci will be useful for investigating genetic diversity and as a simple way of estimating ploidy of wild populations of Solanum centrale. Expand
