In addition, it will provide connectivity and continuity to the “Eastern Road Corridor”, which starts in the city of Santo Domingo traverses the country’s Eastern Region (Figure 1-1). The SEOPC has selected the Moya – Odebrecht Consortium as the company responsible for developing the Detailed Engineering, Construction and Operation phases under a contracting scheme known as Public – Private Participation Scheme (PPP Participación Pública-Privada in Spanish). The Environmental Impact Assessment (EsIA) for the Project was conducted by Golder Associates Inc. in collaboration with RCMA GeoIngeniería CxA and other specialists according to the Terms of Reference provided by the Secretariat of State for Environment and Natural Resources (SEMARN) dated August 26, 2005 and renewed on March 21, 2007 according to Dossier Code No. 2336. Golder Associates Inc. is a consulting firm registered as an environmental services provider before the Sub-secretariat of Environmental Management of SEMARN with Register No. 07-156, as is RCMA GeoIngeniería CxA with Register No. 01-053. The Environmental Impact Assessment includes the perceptions, opinions and concerns gathered during a Citizen Participation process carried out during the EsIA. The EsIA also includes feedback from specialists from SEOPC and the Moya – Odebrecht Consortium. The Final EsIA Report is organized according to the requirements established by the Environmental Authority (SSGA - SEMARN) in the Terms of Reference (TOR), as described below: Section 1 Executive Summary Section 2 Project Description Section 3 Environmental and Social Baseline Section 4 Institutional and Legal Framework Section 5 Stakeholder Consultation Section 6 Environmental Impact Identification, Characterization and Assessment Section 7 Environmental Management and Adaptation Program The following sections present a summary of the EsIA content. Golder Associates July 2007 1-2 07387518 FIGURE 1-1 Eastern Road Corridor Golder Associates July 2007 1-3 07387518 1.2 Project Description 1.2.1 Project Rationale Justification of the Autopista del Coral project is explained below: • The Autopista del Coral represents the missing link in a 224km road corridor that will directly link the city of Santo Domingo with the tourist areas of La Romana, Bayahibe, Higüey, and Verón and with those areas in the so called “Deep East” that include Punta Cana, Bávaro, Cap Cana, Cortecito, Macao, and Uvero Alto. • The proposed road will provide visitors to the eastern tourist areas with easy access to the commercial, recreational and cultural activities in the city of Santo Domingo and other areas in the Eastern region of the Dominican Republic. • The proposed project will play a vital role in interconnecting the main ports, airports, marinas and tourist areas of the region by offering tourists a quick and safe access road. • With design speeds of 100 Km/h in all road sections, the East Corridor (including the Autopista del Coral Project section) will allow travel from Santo Domingo to Punta Cana International Airport in less than two hours. Currently, it takes about 4 hours to travel this route. • Tourism is the main source of economic growth in the Dominican Republic and the greatest generator of foreign currency income. Tourism contributes 40% to the national economy, represents 22% of GDP, and generates 19.2% of the country’s direct and indirect jobs. • The tourism sector in the Dominican Republic had the highest growth in Latin America, with 7.5 % in year 2005. • The tourist areas in the country’s eastern region (La Romana, Bayahibe, Dominicus, Punta Cana, Bávaro, Macao, and Uvero Alto) contain approximately 60% of the 60,000 t rooms that constitute the country’s hotel availability. This area had an 82% average occupancy rate in year 2005. An increase of 10,000 hotel rooms is projected for the next three years in the Bávaro, Punta Cana and Cap Cana zone. • The international airports located in the East Corridor (Las Américas, La Romana, Punta Cana) receive more than 75% of the foreign visitors to the Dominican Republic every year. Golder Associates July 2007 1-4 07387518 1.2.2 Analysis of Route Alternatives The route selection for the Autopista del Coral analyzed three alternative routes: Alternative 1: San Pedro de Macorís – Higüey - Verón Alternative 2: La Romana – La Cruz de los Rondones – Arena Gorda Alternative 3: La Romana – Higüey – Punta Cana The alternatives analysis determined that alternatives 1 and 2 would have lengths of 95 km and 80 km, respectively. The route for Alternative 1 would go through flat topography, while the route for Alternative 2 would cross undulating topography. Both routes were predicted to directly impact towns located within the proposed road corridors. In the case of Alternative 3, the estimated length of the route is 70 km, with the route crossing mostly flat areas with a few undulating zones. Alternative 3 is not projected to directly impact any community in its corridor. Finally, when comparing the three alternatives; alternative 3 has better

[email protected]. ABSTRACT One of the main assumptions of Janzen’s mountain passes hypothesis is that due the low overlap in temperature regimes between low and high elevations in the tropics, organisms living in high-altitude evolve narrow tolerance for colder temperatures while low-altitude species develop narrow tolerance for warmer temperatures. Some studies have questioned the generality of the assumptions and predictions of this hypothesis suggesting that other factors different to temperature gradients between low and high elevations may explain altitudinal distribution of species in the tropics. In this study we test some predictions of the Janzen’s hypothesis at local scales through the analysis of the individual thermal niche breadth in populations of livebearing fishes of the genus Limia and its relationship with their altitudinal distribution in some islands of the Greater Antilles. We assessed variation in tolerance to extreme temperatures (measured as critical thermal minimum (CTmin) and maximum (CTmax) and compared thermal breadth for populations of eight species of Limia occurring in three Caribbean islands and that occupy different altitudinal distribution.

  • The Evolution of the Placenta Drives a Shift in Sexual Selection in Livebearing Fish

  • Population Density of Cebus Imitator, Honduras
    Neotropical Primates 26(1), September 2020 47 POPULATION DENSITY ESTIMATE FOR THE WHITE-FACED CAPUCHIN MONKEY (CEBUS IMITATOR) IN THE MULTIPLE USE AREA MONTAÑA LA BOTIJA, CHOLUTECA, HONDURAS, AND A RANGE EXTENSION FOR THE SPECIES Eduardo José Pinel Ramos M.Sc. Biological Sciences, Universidad Nacional Autónoma de Honduras, Cra. 27 a # 67-14, barrio 7 de agosto, Bogotá D.C., e-mail: <[email protected]> Abstract Honduras is one of the Neotropical countries with the least amount of information available regarding the conservation status of its wild primate species. Understanding the real conservation status of these species is relevant, since they are of great importance for ecosystem dynamics due to the diverse ecological services they provide. However, there are many threats that endanger the conservation of these species in the country such as deforestation, illegal hunting, and illegal wild- life trafficking. The present research is the first official registration of the Central American white-faced capuchin monkey (Cebus imitator) for the Pacific slope in southern Honduras, increasing the range of its known distribution in the country. A preliminary population density estimate of the capuchin monkey was performed in the Multiple Use Area Montaña La Botija using the line transect method, resulting in a population density of 1.04 groups/km² and 4.96 ind/km² in the studied area. These results provide us with a first look at an isolated primate population that has never been described before and demonstrate the need to develop long-term studies to better understand the population dynamics, ecology, and behaviour, for this group in the zone.

It is being submitted for the Degree of Doctor of Philosophy in the University of the Witwatersrand, Johannesburg. It has not been submitted before for any degree or any other examination in any other University. ______________________ ______ day of ______________________ 20_____ ii ABSTRACT Introduced plants will lose interactions with natural enemies, mutualists and competitors from their native ranges, and possibly gain interactions with new species, under new abiotic conditions in their new environment. The use of biocontrol agents is based on the premise that introduced species are liberated from their natural enemies, although in some cases introduced species may not become invasive because they acquire novel natural enemies. In this study I consider the potential for the biocontrol of Bryophyllum delagoense, a Madagascan endemic, and hypothesize as to why this plant is invasive in Australia and not in South Africa. Of the 33 species of insects collected on B. delagoense in Madagascar, three species, Osphilia tenuipes, Eurytoma bryophylli, and Rhembastus sp. showed potential as biocontrol agents in Australia.

    Classification of Tropical Vegetation by Dominica Elaine Harrison A thesis submitted in partial fulfillment of the requirements for the degree of Master’s of Science Earth and Atmospheric Sciences University of Alberta © Dominica Elaine Harrison, 2016 Thesis abstract The increasing anthropogenic pressure on biodiversity in the tropics is resulting in changes to ecosystem structure and increasing species extinction rates (Collen et al. 2013). These issues are heightened in the tropics where 50% of the world’s biodiversity is held in 7% of the world’s terrestrial landmass (Urquhart 2001). The biodiversity of vegetation has been used as an indicator of the overall health and processes occurring in a biological system. This thesis explores ways to quantify the biodiversity of vegetation using different avenues of vegetation classification. In the second chapter of this thesis the leaf economic spectra (LES), a vegetation classification that attempts to provide a general framework to assess plant functional diversity, is used to explore the relationships between the conventional plant functional traits with the newly applied anatomical traits (Wright et al. 2004). This system uses economic principles to help understand plant ecology trade-offs and performance strategies. The LES was used to discern two plant functional groups (PFG), lianas and tree species, at two different Panamanian tropical sites, a tropical wet forest and a tropical dry forest. This was accomplished by examining the interactions between commonly used whole-leaf traits from the LES and newly applied anatomical traits. The addition of anatomical traits to the LES is a new approach (Reich 2014). The findings of this investigation support the hypothesis that trees are resource conservative when compared to their liana counterpart, which are thought to be resource acquisitive (Schnitzer 2005; Asner and Martin 2012).
