Sperm competition: linking form to function
TLDR
It is shown that increased sperm length is unlikely to be driven by selection for increased swimming speed, and that the relative lengths of a sperm's constituent parts, rather than their absolute lengths, are likely to be the target of selection. Expand
Variability in Isotope Discrimination Factors in Coral Reef Fishes: Implications for Diet and Food Web Reconstruction
TLDR
The results confirm that the use of meta-analysis averages for ΔN is likely to be inappropriate for accurately determining diets and trophic relationships using tissue stable isotope ratios. Expand
Positive Allometry and the Prehistory of Sexual Selection
TLDR
The results question the popular view that the elaborated structures of these fossil species evolved as thermoregulatory organs and provide evidence in support of the hypothesis that Pteranodon crests and eupelycosaur sails are among the earliest and most extreme examples of elaborate sexual signals in the evolution of terrestrial vertebrates. Expand
Sperm Morphology and Velocity are Genetically Codetermined in the Zebra Finch
TLDR
It is shown that sperm velocity is positively phenotypically correlated with measures of sperm length in the zebra finch Taeniopygia guttata, and that selection for faster sperm will simultaneously lead to the evolution of longer sperm. Expand
RELATIONSHIPS BETWEEN SPERM LENGTH AND SPEED DIFFER AMONG THREE INTERNALLY AND THREE EXTERNALLY FERTILIZING SPECIES
TLDR
The results reveal that correlations between sperm size and speed are indeed present and possibly more common than currently thought, however, the direction of the correlationsBetween sperm length and speed were influenced by fertilization mode in contrasting and unexpected ways. Expand
Stable isotope analysis reveals community-level variation in fish trophodynamics across a fringing coral reef
In contrast to trophodynamic variations, the marked zonation in physical and biological processes across coral reefs and the concomitant changes in habitat and community structure are wellExpand
Design of a Hybrid Reed Bed System to Achieve Complete Nitrification and Denitrification of Domestic Sewage
TLDR
By combining horizontal- and vertical-flow systems in the appropriate process sequence it is thus possible to produce a system which removes BOD5, TSS and achieves complete nitrification as well as substantial removal of nitrate and hence a lowered Total N. Expand
Oceanographic forcing of nutrient uptake and release over a fringing coral reef
Nitrate and nitrite (NO x) and phosphate (PO 4) dynamics over Ningaloo Reef, Western Australia, are shown to depend on oceanographic forcing of coupled mass transfer limited (MTL) gross uptake andExpand
Density- and trait-mediated effects of a parasite and a predator in a tri-trophic food web
TLDR
A mixture of density-mediated and trait-mediated indirect effects of parasitism on non-host species creates rich and complex possibilities for effects of parasites in food webs that should be included in assessments of possible impacts of parasite eradication or introduction. Expand
Estimation of intergenerational drift dispersal distances and mortality risk for aquatic macroinvertebrates
TLDR
This work is able for the first time to estimate an upper bound for the mortality risk associated with entering the drift, which, for the G. pulex population under consideration, is less than 1% for individual drift events. Expand
