Plankton merupakan komponen utama rantai makanan di ekosistem perairan. Fitoplankton banyak ditemukan permukaan perairan pada siang hari, sedangkan zooplankton malam hari. berperan penting sebagai bioindikator untuk mengetahui kesuburan dan perubahan kondisi lingkungan Perubahan akan berdampak penurunan kelimpahan, keanekaragaman distribusi plankton. Keberadaan plankton juga dipengaruhi oleh fa...
The severity of damage to host plants by omnivorous pests can vary according to the availability of plant and animal prey. Two omnivorous mole crickets, Scapteriscus vicinus Scudder and S. borellii Giglio-Tos, were used to determine if the availability of prey influences damage to hybrid bermudagrass by adult mole crickets. Experiments were conducted in arenas with either grass alone (control)...
The initiation of intracellular infection of legume roots by symbiotic rhizobia bacteria and arbuscular mycorrhiza (AM) fungi is preceded by the induction of calcium signatures in and around the nucleus of root epidermal cells. Although a calcium and calmodulin-dependent kinase (CCaMK) is a key mediator of symbiotic root responses, the decoding of the calcium signal and the molecular events dow...
The relationship between biodiversity and ecosystem functioning is a central issue in ecology. Previous studies have shown that producer diversity can impact the consumer community via predator-prey interactions. However, direct observations of this relationship remain rare, in particular for aquatic ecosystems. In this research, the relationship between phytoplankton diversity (species richnes...
BACKGROUND Cyclops syndrome is characterized by loss of terminal knee extension due to proliferative fibrous nodule formation in the intercondylar notch. This complication occurs in the early postoperative period after anterior cruciate ligament reconstruction (ACLR). The pathogenesis of Cyclops syndrome is not well understood. HYPOTHESIS Persistent hamstring contracture after ACLR is associa...
of fresh fish bile on guinea-worm embryos and also on cyclops infected as well as uninfected. It was found that fresh bile of the following species of fish, Barbus puckelli, Barbus punctatus and Barbus gelius, exerts a definite lethal action on cyclops and also on guinea-worm embryos. When undiluted fresh bile was used, it was found that it took about one to two minutes to kill the cyclops and ...
Precise regulation of the signaling range of secreted molecules is essential for proper pattern formation during development. The Nodal family of TGF-beta proteins has been shown to function as both short- and long-range signals. But the underlying mechanisms remain elusive. In this study, we investigated the regulation of the signaling range of zebrafish Nodal proteins Cyclops and Squint, whic...
