Exocytosis is a general term used to denote vesicle fusion at the plasma membrane, and it final step in secretory pathway that typically begins endoplasmic reticulum (ER), passes through Golgi apparatus, ends outside of cell. Endocytosis refers recovery
For nearly three decades, the Whitfield (1992) characterisation scheme served as a reference framework to type South African estuaries. We outline revised ecosystem classification that incorporates biogeographical zonation and introduces new types. Coastal outlets were re-categorised estuaries or micro-systems. functional estuaries, Estuarine Lakes, Bays Predominantly Open Estuary types largely retained. New are Lagoons Arid Closed Estuaries. The numerically dominant, temporarily open/closed...
Abstract Ocean acidification (OA) refers to a global decline in the average pH of seawater driven by absorption atmospheric carbon dioxide (CO 2 ). Marine macroalgae, while affected this change, are also able modify through their own interaction with inorganic carbonate system. Through action, macroalgae-dominated habitats potential refugia from OA for associated marine species. This review summarises most prominent literature on role macroalgae mitigation and macroalgal serve as refugia. It...
In 2005/2006 a multidisciplinary research programme that included studies on the hydrodynamics, sediment dynamics, macronutrients, microalgae, macrophytes, zoobenthos, hyperbenthos, zooplankton, ichthyoplankton, fish and birds of temporarily open/closed East Kleinemonde Estuary was conducted. Particular attention given to responses different ecosystem components opening closing estuary mouth how this is driven by both riverine marine events. Using complementary dataset daily conditions...

Abstract One of the most critical ecosystem functions provided by shallow coastal habitats is as nurseries for juveniles fish. Many studies that have assessed nursery function structurally complex compared seagrass with unstructured sand and mud such, has emerged important habitat juvenile fishes. Although considerably less work focussed on provision macroalgae within seascapes, recent started to highlight canopy-forming may in fact be comparable seagrass. This review collates research...
Background. The composition of the microbiome in human body sites plays an important role health. vaginal environment is colonized by several species bacteria that have a major influence on reproductive advancement sequencing technologies has made assessment microbiota possible through microbial DNA extraction and sequencing. Therefore, it paramount importance to select sensitive reproducible method, facilitates isolation with sufficient quantity purity, from living environment. Here, we...
Coastal ecosystems serve as important nursery areas, yet they are facing many challenges. For example, eutrophication-induced hypoxia is one of the major threats to functioning coastal ecosystems, particularly estuaries. The Sundays and Swartkops estuaries both experience persistent eutrophic conditions, with frequent phytoplankton blooms (>20 μg Chl-a l−1) that result in instances bottom-water oxygen depletion (<4 mg/l). Bi-seasonal sampling physico-chemical parameters demersal fishes...
Understanding the dietary preferences of endangered species can be useful in implementing conservation strategies, including habitat restoration, translocation, and captive breeding. Environmental DNA (eDNA) from feces provides a non-invasive method for analysing animal diets. Currently, metabarcoding, PCR-based approach, is choice such data. However, this has limitations, specifically PCR bias, which result overestimation importance certain taxa failure to detect other because they do not...
Abstract Physiological rates and processes underpin the relationships between ectothermic organisms, such as fish, their environment. The response persistence of fish populations in an increasingly variable ocean is dependent on distribution diversity physiological phenotypes. Growing evidence suggests that fisheries exploitation can selectively target certain behavioural phenotypes, which may shift exploited to altered states. Here we test if commercial have potential do this a “natural...
Abstract The distributions of ectothermic marine organisms are limited to temperature ranges and oxygen conditions that support aerobic respiration, quantified within the metabolic index (ϕ) as ratio supply demand. However, utility ϕ at local scales across heterogenous environments is unknown; yet, these often where actionable management decisions made. Here, we test if can delimit entire distribution when calibrated an appropriate range (~10 km) using endemic reef fish, Chrysoblephus...
Surimi is a concentrate of myofibrillar proteins obtained from solid residues fish processing, which minced, washed, drained and final by the use stabilizing agents. The aim this study was to evaluate influence using different species: whitemouth croaker (Argyrosomus regius), snapper (Lutjanus purpureus), sandperch (Pseudopercis Numida) tilapia (Oreochromis niloticus). surimi preparation method included immersion in an alkaline solution, followed two immersions saline solutions, water...
Understanding the vulnerability and resilience of coastal ecosystems associated species to climate change is important in planning for a future climate. South Africa’s estuaries are dominated by juvenile marine fish species, with 19 entirely dependent on estuarine nurseries. Juvenile tolerant both extreme hot cold temperatures, stressors (e.g. droughts, floods sea level rise) having direct indirect effects through habitat transformation. By reducing some non-climate impacts fish, such as...
Abstract Background/Aims Juvenile idiopathic arthritis (JIA) is a relatively common chronic paediatric condition with significant potential for lifelong morbidity. Despite advances in medical treatment technologies, persistent discrepancy between ‘ideal world’ (clinical research) and ‘real practice) data suggests quality of care JIA has room improvement. Furthermore, understanding prioritising the outcomes that matter to children families will improve experience clinical reduce impact on...
