This algal class has, therefore, traditionally been regarded as providing the bulk of the food that sustains the marine food chain to top consumers and important fisheries. However, this beneficial role has recently been questioned on the basis of laboratory studies showing that although dominant zooplankton grazers such as copepods feed extensively on … Continue reading “Latest Research on Copepod: Feb 2021”

Fire Ant Mound Densities in the United States and Brazil (Hymenoptera: Formicidae) To compare fire ant populations (Solenopsis) in North and South America, we surveyed 102 preselected roadside sites, half in the southeastern United States and half in the state of Mato Grosso do Sul, Brazil. Fire ants were considerably more abundant in the United States. [1] The relation between caste ratios and division of labor in the ant genus Pheidole (Hymenoptera: Formicidae) Ten species of Pheidole, representing as many … Continue reading “Latest Research on Formicidae : March – 2020”
