“…Possible explanations may include the death of older sires, older sires becoming reproductively senescent or unable to compete with the younger sires, or an inability of the oldest sires to reproduce based on life-time accumulation of environmental contaminants such as PCBs that can interfere with reproduction (Wells et al, 2005). The increase in new sires may also be related to the observed decline and leveling off of environmental contaminants such as PCBs in Sarasota Bay dolphins (Kucklick et al, 2022) with concomitant changes in the age structure of the males of the SBDC showing males to live longer.…”

Genetic analyses, initiated in 1984, have played a major role in our understanding of the structure and social relationships of the long-term resident community of common bottlenose dolphins (Tursiops truncatus) in Sarasota Bay, Florida (SBDC). One component of our ongoing study of the community’s social system involves using blood samples from periodic catch-and-release sampling for life history and health assessment studies, as well as skin from biopsy dart sampling studies and strandings, to investigate paternity and mating strategies in this community. These analyses, covering a span of four generations of calves, were originally based on chromosomes and protein electrophoresis, but with the advent of microsatellite DNA technology, the latter has become our analysis of choice. We have performed paternity analyses on 204 known mother-calf pairs. For 151 of the calves (74%), sires were identified within the SBDC, but for the remaining 26% of the calves all sampled males associated with the community were excluded and it is likely that a substantial contribution of paternity to the SBDC comes from outside the community. Of the SBDC males, only 52 males of the more than 200 potential sires were sires. The age of sires at time of conception of a calf ranged from 10 to 43 years, averaging 24 years old. These males have sired 1-7 calves during a documented period of reproductive tenure of as much as 24 years (average = 21.4 years). Four males have sired 6-7 calves each, these males siring calves in the community for more than 20 years. Another 19 males have each sired 3-5 calves and the remaining 30 males were identified as sires of 1-2 calves. Paired males sired 75% of the calves while 25% of the calves were sired by unpaired males. Females with multiple offspring generally had multiple sires for these offspring. These paternity analyses support the hypothesis that a major avenue of gene flow in the SBDC is through the males given their greater ranges, with occasional exchange via visits from males from other areas, as well as the occasional brief movements of females from outside the community range into the community.

“…In different phrases, persistent organic pollution (POPs) are organic compounds which can be present in marine environments round the arena due to their resistance to environmental degradation. Their excessive lipophilicity makes them able to bioaccumulating in massive quantities within the tissues of marine organisms [4]. Marine waters are suffering from continual pollution that continue to be for lengthy intervals of time and come to be to be had to marine biota, main to a negative impact on population and individual health after they reach them thru water or atmospheric shipping.…”

Persistent Organic Pollutants (POPs) are organic compounds that have been banned or restricted for all purposes. Banning these compounds does not guarantee that the chemicals will not be found in the environment. This is related to the persistence nature of POPs. To investigate the presence of POPs in the environment. Environmental monitoring of POPs is one of the efforts to support POPs management. The most frequently discussed pollutants in the last 3 years are polychlorinated biphenyls (PCBs). In addition, an effective method in degrading Persistent Organic Pollutants is the fabrication of ultra-thin graphitic carbon nitride decorated CoFe2O4/Mn3O4 nanosheet membranes with a yield of 94.5% and a kinetic rate (0.1367 min.-1) For norfloxacin (NOR) within 30 minutes. But for a method that uses simple, efficient and affordable technology to remove organic pollutants from aquatic systems is Biosorption using biomass waste, using tannin-rich waste such as coffee grounds and green tea grounds capable of degrading 10 μM chlordecone.
