Do Moderate-Luminosity Active Galactic Nuclei Suppress Star Formation? [PDF]

, 2009
The growth of supermassive black holes and their host galaxies are thought to be linked, but the precise nature of this symbiotic relationship is still poorly understood. Both observations and simulations of galaxy formation suggest that the energy input

Density-and trait-mediated effects of a parasite and a predator in a tri-trophic food web [PDF]

, 2014
1. Despite growing interest in ecological consequences of parasitism in food webs, relatively little is known about effects of parasites on long-term population dynamics of non-host species or about whether such effects are density- or trait- mediated ...

Genetic characterization of Angiostrongylus larvae and their intermediate host, Achatina fulica, in Thailand

PLoS ONE, 2019
Angiostrongyliasis is a parasitic disease caused by nematodes of the genus Angiostrongylus. Distribution of this worm corresponds to the dispersal of its main intermediate host, the giant African land snail Achatina fulica.
