Bacheler, Nathan Mitchell. "Ecology of bigmouth sleepers (Eleotridae: Gobiomorus dormitor) in a Puerto Rico reservoir." NCSU, 2002. http://www.lib.ncsu.edu/theses/available/etd-20020325-124802.
Full textThe bigmouth sleeper Gobiomorus dormitor is an eleotrid species found in southernFlorida and Texas, along the Atlantic coast of Central and South America, and theCaribbean Islands. This species is important in terms of recreational and consumptivefishing, and conservation. Bigmouth sleepers are harvested by anglers in parts of their range, while in Florida hydrological changes, habitat loss, and reduced waterquality have reduced the species? already small geographical distribution,necessitating conservation measures. There is a paucity of data regarding the biologyof bigmouth sleepers, but accurate knowledge of this species? ecology and behavioris crucial to effective conservation and management plans. Although bigmouth sleeperstypically inhabit lotic habitats, they have been found in four reservoirs in PuertoRico. In Carite Reservoir, abundance and size data indicate that habitat is suitablehabitat for bigmouth sleepers, and the presence of a diversity of size classes ofsleepers suggests that either in-reservoir reproduction or significant recruitmentto the reservoir from an outside source is occurring. This research was initiatedto evaluate the likelihood of each, and to learn more broadly about bigmouth sleeperecology. Population biology, diet, and reproduction of bigmouth sleepers in CariteReservoir were examined between 1999 and 2001. Many sizes of bigmouth sleepers werecollected during this study, ranging from 25 to 400 mm TL. The estimated totalpopulation size in 2000 and 2001 was 1,783 and 3,353 fish, respectively. Daily growthrate of tagged fish ranged from ?0.08 to 0.10 mm/day, and was negatively correlatedwith length of fish at marking. Diet of small bigmouth sleepers (50 ? 100 mm TL) mainlyconsisted of insects, whereas larger fish primarily preyed upon fish and freshwatercrabs. Sexual dimorphism of bigmouth sleepers was evident in the anatomy of theirurogenital papillae; these differences developed at sizes as small as 50 mm TL and persisted throughout the year. Reproduction was seasonal, with the highest gonadosomaticindicies occurring in May and June and the lowest in January and February. The smallestmature male observed was 159 mm TL, while the smallest mature female was 179 mm TL. Size frequency distributions of oocytes in female ovaries during the reproductiveseason typically fell into two size groups, a group of primary oocytes (< 0.20 mm)and one group of maturing oocytes (> 0.20 mm). The largest oocytes observed were 0.70mm from a 270-mm female. Fecundity was negatively correlated with date, suggestingbatch spawning. Fecundity was relatively high (mean = 140,836) and was positively correlated with female body weight. Results of this research not only provide managersand conservationists a better understanding of bigmouth sleepers in Puerto Rico reservoirs, but also contribute to the knowledge of this species? ecology throughoutits range.

Puerto Rico, an island in the Caribbean, has long sought to develop a high-tech economy and has struggled in the process. Two initiatives, Puerto Rico TechnoEconomic Corridor (PRTEC) and the Eastern Central Technological Initiative (INTECO) seek to encourage local firm formation, attract foreign capital, and improve infrastructure to develop a high-tech economy and an innovation culture in the island. The efforts of the initiatives focus on cooperation from the private sector, the government, and academia. Henry Etzkowitz's triple helix model of university-industry-government relations explains the synergies and organizational infrastructure needed to ensure a sustainable economic growth based on technology and innovation. This thesis focuses on the two initiatives in Puerto Rico whose goal is to promote a high-tech economy in the island. The analysis focuses on the initiatives' relationship with the triple helix's three sectors and how they have been working together to achieve their goals. While the initiatives have made significant progress in firm formation through incubators and community outreach programs to educate about technology, organizational barriers such as lack of transparency in the local grant seeking process and the lack of an entrepreneurial culture have not allowed the initiatives to solidify themselves as the generators of the new knowledge-based economy in Puerto Rico.

Find full textPuerto Rico’s lack of effective and affordable energy substitutes after Hurricane Maria resulted in a mortality increase of 4,970 residents (Verma, Murray, and Mamdani, 2018). Puerto Rico’s Island dependency on electric power and no energy substitutes available have provoked a risk to human life after catastrophic events. The problem was measured by comparing Puerto Rico’s reliance on fossil fuels with accessible and economical renewable energy options. Solar photovoltaic (PV) technologies are the optimum alternative to transition from fossil fuel usage to renewable energy. Previous research has demonstrated the impact of using solar panels instead of an electric grid due to the constant solar radiation throughout the year. The analyzed data and projections showed a reduction in fossil fuels and carbon dioxide emissions by implementing solar photovoltaic technologies. The installation of PV systems in landfills, household roofs and transitioning to solar public lighting positively impacts the atmosphere carbon dioxide emissions.
