Fish Diversity And Distribution In The Seagrass-Coral Reef Continuum At Two Sites Off The Western Coast Of Isla Bastimentos, Bocas Del Toro, Panama, Kathy Liu
Independent Study Project (ISP) Collection
Coral reefs are the most diverse marine ecosystem and the largest biogenic structure on Earth. They serve as shelter for many reef fishes and are a food source for resident and visiting fish species. In the tropics, coral reefs are often in close proximity to seagrass beds and the two contiguous marine habitats are not only highly interconnected but also highly understudied. The seagrass-coral reef continuum offers a wide array of services to human society as well as to various life stages of reef fishes resulting in diel, temporal, or yearly migrations of fish between the two habitats. Tropical reef …
Large Mammals Of The High Andes A Survey Of Community Composition And Habitat Usage In The Highlands Of Angochagua, Sage Fox
Independent Study Project (ISP) Collection
The large mammal community of the high Andes may be the least understood in South America. It contains multiple threatened and charismatic species including the Andean Bear, Mountain Tapir, Red Brocket Deer, Northern Pudu, and Puma. Many of these species are lacking in distribution and population data. The highlands of the Parroquia de Angochagua were once overgrazed by livestock, but have been mostly restored over the last 20 years through conservation efforts by the local community. These highlands are thought to have populations of all the previously mentioned species, though they had not been surveyed before this study. Transect surveys …
Demography And Behavior Of Critically Endangered Alouatta Coibensis Trabeata Troops In Forest Fragments In And Around Mata Oscura, Veraguas On The Azuero Peninsula Of Panamá, Billy Allen
Independent Study Project (ISP) Collection
The endemic Azuero howler monkey, Alouatta coibensis trabeata, was studied in three sites in and around the Mata Oscura community in Veraguas, Panamá in the western region of the Azuero Peninsula. A. coibensis trabeata is a critically endangered subspecies of A. coibensis that is threatened by continued habitat destruction and human encroachment throughout its entire distribution on the Azuero Peninsula. Sites included the Mata Oscura community (site 1), the Arenas community periphery (site 2), and the Cerro Hoya National Park (site 3). Demography, behavior, and habitat were assessed over 9 days of study in November. Troops were encountered in sites …
Differences In Temporal And Territorial Feeding Patterns Of Various Tropical Trochilidae Species As Observed At Two Different Ecosystems In Soberanía National Park, Delaney Vorwick
Independent Study Project (ISP) Collection
This study aims to illustrate differences in feeding patterns and displays of territorialism at two artificial feeding sites, located in two ecosystems; one site in a secondary forest of Soberanía National Park, the other in a residential area in the nearby town of Gamboa. Four 1-hour observation periods were recorded each day for four days at both sites. During each period of observation, the allocation of time to the three activities of perching, flying, and feeding was recorded, along with the number of visits the feeders. Notes were taken on patterns of territoriality as connected to species and sex. Significance …
The Influence Of Habitat Preference On Longitudinal Population Composition And Distribution Of Groupers (Serranidae) In Chumbe Island Coral Park, Zanzibar Tanzania, Caroline Daley
Independent Study Project (ISP) Collection
A survey of six common grouper (Serranidae) species was conducted on both the western protected and eastern unprotected reefs around Chumbe Island. Species, estimated maturity, and fundamental niche and general habitat preference was extrapolated based on observed realized niche and qualified according to substrate, depth, slope position, and general reef region. Abundance, biomass density, and biodiversity of Serranid populations were compared among locations on the reef with habitat preference in mind in order to best assess how habitat influences population composition, distribution, and health. The results of this study provide depth to previous research on the protected reef and indicate …
Andean Condor Nesting And Behavior: A Study Of A Free-Living Pair And Chick As Well As Population Behavior Near Antisana Ecological Reserve, Ecuador, Ian Handler
Independent Study Project (ISP) Collection
The behavior of the Andean condor (Vultur gryphus), especially nest behavior, is little known outside of captivity. More information on chick-parent interactions and parenting dynamics of successful condor pairs is needed in order to help create an effective conservation plan for a species in peril of extinction. Study of nest home used by a free-living pair of condors and home to a five-month old juvenile began on November 11, 2018 and continued through November 29, 2018. The nest is located in Antisanilla Biological Reserve and nearby Antisana Ecological Reserve. The chick was also tagged with numbers and a tracking device …
Herpetofauna Of Sumak Allpa: A Baseline Assessment Of An Unstudied Island Herpetofaunal Community, Sara Freimuth
Herpetofauna Of Sumak Allpa: A Baseline Assessment Of An Unstudied Island Herpetofaunal Community, Sara Freimuth
Independent Study Project (ISP) Collection
Sumak Allpa is an island dedicated to the provision and protection of habitat for the conservation and rehabilitation of primates. As such, the island - a varzea ecosystem located in the Western Amazon of Ecuador, one of the most biodiverse and also most threatened regions in the world – consists of protected primary forest that is home not only to a variety of primates, but also to an even wider variety of other taxa, nearly all of which have gone unstudied on the island. The present investigation assessed two of those taxa, amphibians and reptiles, in order to establish a …
Blooming Mountains Of Biodiversity: An Investigation Of Angiosperms On Cerro Mayordomo, Tungurahua, Ecuador, Ella Matsuda
Blooming Mountains Of Biodiversity: An Investigation Of Angiosperms On Cerro Mayordomo, Tungurahua, Ecuador, Ella Matsuda
Independent Study Project (ISP) Collection
Ecuador is one of the most biodiverse places on the planet, and many of the species in the region are found nowhere else in the world. The cloud forest is particularly diverse because the mountainous terrain isolates populations and changes in elevation create a wide variety of habitats. Cerro Mayordomo is a relatively unexplored mountain in the cloud forest of Tungurahua, Ecuador. It is known to have very high levels of endemism and several new species have been discovered there, but the biodiversity of angiosperms on the mountain has never been quantified. In this study, 5x5 m quadrants were established …
