Nearshore Vertical Distribution Of Barnacle Cyprids: Temporal Patterns And Hydrographic Variability, Gabriela Yamhure
Nearshore Vertical Distribution Of Barnacle Cyprids: Temporal Patterns And Hydrographic Variability, Gabriela Yamhure
Theses
Most benthic organisms living in the intertidal zone have planktonic larvae that reside temporarily in the water column before settling in their adult habitats. Larvae aggregate in offshore larval pools, and transport horizontally and vertically in the water to remain in the nearshore and during their pelagic life. While some horizontal transport of larvae can be attributed to advection, behavioral responses, like vertical swimming and buoyancy control, allow larvae to position themselves at depths where flow direction can be exploited. Thus, knowledge on how vertical larval distribution relates to physical processes can be fundamental to better understand larval transport. These …

Investigation Into The Mechanism Of Ion Transport In Rio Negro Characiformes, Vineza D. Reduta
Undergraduate Honors Theses
Four fish species within the Characiform Order [(Rosy tetras (Hyphessobrycon rosaceus), Serpae tetras (Hyphessobrycon eques), Emperor tetras (Nematobrycon palmeri) and Penguin tetras (Thayeria obliqua)] are native to the ion-poor, acidic waters of the Rio Negro. In this paper, we focus on Wood’s revised Na+/NH4+ exchange model to gain better insight into the mechanisms of ion transport within the Characids. We exposed each species to two experimental treatments: (i) 1mM ammonia (high external ammonia [HEA]), to test coupling of Na+ uptake and ammonia excretion, and (ii) 100μM Acetazolamide …
