Studies of fecal pellet flux show that a large percentage of pellets produced in the upper ocean is degraded within the surface waters. It is therefore important to investigate these degradation mechanisms to understand the role of fecal pellets in the oceanic carbon cycle. Degradation of pellets is mainly thought to be caused by coprophagy (ingestion of fecal pellets) by copepods, and especial...

Aims: To investigate the combined effect of Arbuscular Mycorrhizal Fungi (AMF) and intercropping on control nematode Radopholus similis in banana.
 Study Design: The study involved an experiment which banana-banana monocrops alongside banana-groundnut banana-sweet potato intercrops were inoculated with AMF Rhizophagus irregularis MUCL 41833 to R. similis.
 Place Duration Study: Centre...

Five new species of Paectes Hübner [1818] related to Paectes arcigera (Guenée) (Puerto Rico, U.S. Virgin Islands, British Virgin Islands, Guadeloupe, Dominica, St. Lucia, Trinidad) and Paectes longiformis Pogue (Brazil) are described: Paectes asper sp. n.

Abstract: Aim In this study, we investigated the effects of secondary PET microplastics (< 53 µm) on Daphnia similis basic life-history parameters survival, age at first reproduction and total offspring number. We also analyzed D. enzymatic activity (superoxide dismutase, catalase glutathione-S-transferase) sub-effect concentrations. Methods performed acute chronic toxicity tests using six c...
