Particulate nutrient fluxes over a fringing coral reef: relevant scales of phytoplankton production and mechanisms of supply
TL;DR: Seasonal observations of phytoplankton uptake at Ningaloo Reef, Western Australia, reinforce the importance of particulate organic nitrogen (PON) and carbon (POC) in reef nutrient budgets and identify wave action and the dynamics of regional currents as important factors determining plankton supply to the reef.
Sperm Morphology and Velocity are Genetically Codetermined in the Zebra Finch
TL;DR: 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.

Stable isotope analysis reveals community-level variation in fish trophodynamics across a fringing coral reef
TL;DR: In this paper, the authors demonstrate consistent spatial changes in the community-level trophodynamics of 46 species of fish across the fringing Ningaloo Reef, Western Australia, using tissue stable isotope and fatty acid analyses.

Filter feeders and plankton increase particle encounter rates through flow regime control
TL;DR: Numerical simulations reveal that the encounter rate is Reynolds number dependent and that encounter efficiencies are consistent with the sparse experimental data, which has great implications for understanding of selection pressure on the physiology and ecology of organisms.

Positive Allometry and the Prehistory of Sexual Selection
TL;DR: 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.
