The insidious effect of diatoms on copepod reproduction The productive regions of the ocean are characterized by seasonal blooms of phytoplankton which are generally dominated by diatoms. 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.

Photoperiod and Temperature Control in the Regulation of Reproduction in the Female Catfish Heteropneustes fossilis The annual reproductive cycle of the catfish Heteropneustes fossilis is split into the preparatory period (February–April), prespawning period (May–June), spawning period (July–August), and postspawning period (September–January). Ovarian recrudescence, which normally occurs during the prespawning period, are often advanced by photothermal manipulations. During the postspawning and preparatory periods, the tempo of ovarian recrudescence is far faster at 30 C than at other temperatures (ambient, 25 or … Continue reading “Latest Research on Heteropneustes Fossilis: Dec – 2019”

The Continuous Plankton Recorder: concepts and history, from Plankton Indicator to undulating recorders Alister Hardy conceived the continual Plankton Recorder (CPR) survey within the 1920s as a way of mapping near-surface plankton in space and time, interpreting the changing fortunes of the fisheries and relating plankton changes to hydrometeorology and climatic change. The seed he planted has grown to become the foremost extensive long-term survey of marine organisms within the world and therefore the breadth of his vision becomes ever … Continue reading “Latest News on Plankton Research: Dec – 2019”

Semiochemical Parsimony in the Arthropoda A wide type of arthropods have tailored their own semiochemicals to aid multiple functions in various contexts. Semiochemicals, the pheromones and allomones, are detected in invertebrate species in six orders, and it’s been clearly established that these compounds ar used with nice parsimony. the flexibility of those invertebrates in exploitation these natural merchandise for an out of this world diversity of functions emphasizes the importance of semiochemicals within the organic process biology of the Arthropoda. … Continue reading “Latest News on Arthropoda Research: Dec – 2019”

THE EVOLUTION OF AGRICULTURE IN BEETLES (CURCULIONIDAE: SCOLYTINAE AND PLATYPODINAE) Beetles within the weevil subfamilies Scolytinae and Platypodinae are unusual in that they burrow as adults inner bushes for feeding and oviposition. Some of these beetles are known as ambrosia beetles for his or her obligate mutualisms with asexual fungi—called ambrosia fungi—which are derived from plant pathogens in the ascomycete organization referred to as the ophiostomatoid fungi. Other beetles in those subfamilies are known as bark beetles and are associated … Continue reading “Latest News on Curculionidae Research: Dec – 2019”
