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 …

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 …

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

Lateral Eyes Direct Principal Eyes As Jumping Spiders Track Objects, Elizabeth M. Jakob, Skye M. Long, Duane P. Harland, Robert R. Jackson, Ashley Carey, Mary Emma Searles, Adam H. Porter, Cristina Canavesi, Jannick P. Rolland

All Peer-Reviewed Publications

One way of circumventing the functional tradeoffs on eye design [1,2] is to have different eyes for different tasks. For example, jumping spiders (Salticidae), known for elaborate, visually guided courtship and predatory behavior [3], view the same object simultaneously with two of their four pairs of eyes: the antero-lateral eyes (ALEs) and the principal eyes (reviewed in [2]; Figure 1A). The ALEs, with immobile lenses and retinas, wide fields of view, and hyperacute sensitivity to moving stimuli [4], are structurally distinct from the principal eyes, which have the best spatial acuity known for terrestrial invertebrates and can discern fine details …

Acarine Biodiversity In Ecuador: Two New Species Of Endoparasitic Chiggers (Acarina: Trombiculidae) From Terrestrial Andean Anurans, Ricardo Guerrero, Mario Humberto Yánez-Muñoz

MANTER: Journal of Parasite Biodiversity

Two species of endoparasitic chiggers, Vercammenia neotropica n. sp. and Microtrombicula ecuadorensis n. sp., are described, both found in terrestrial anurans of the genus Pristimantis collected in the Andes of Ecuador. A new combination is proposed for Trombicula yorkei Sambon, 1928 as Microtrombicula yorkei (Sambon, 1928) n. comb., and Schoengastia lynni Ewing, 1942 is placed as incertae sedis. This is the first record of species of the genus Vercammenia in the Neotropical region.

Comparative Investigations Of Social Context-Dependent Dominance In Captive Chimpanzees (Pan Troglodytes) And Wild Tibetan Macaques (Macaca Thibetana), Jake A. Funkhouser, Jessica A. Mayhew, Lori K. Sheeran, John B. Mulcahy, Jin-Hua Lee

All Faculty Scholarship for the College of the Sciences

Theoretical definitions of dominance, how dominance is structured and organized in nature, and how dominance is measured have varied as investigators seek to classify and organize social systems in gregarious species. Given the variability in behavioral measures and statistical methods used to derive dominance rankings, we conducted a comparative analysis of dominance using existing statistical techniques to analyze dominance ranks, social context-dependent dominance structures, the reliability of statistical analyses, and rank predictability of dominance structures on other social behaviors. We investigated these topics using behavioral data from captive chimpanzees (Pan troglodytes) and wild Tibetan macaques (Macaca thibetana). We used a …

An Observed Instance Of Cooper’S Hawk (Accipiter Cooperii) Predation On A Chicken In An Urban Environment, Don Arp Jr.

Nebraska Bird Review

On February 21, 2015, I had the opportunity to observe a Cooper’s Hawk (Accipiter cooperii) attack, kill, and feed on a chicken in an urban environment.

The attack occurred around 1:10 p.m. on February 21, 2015, in Lincoln, Nebraska, in a residential area that is often referred to as the Bethany neighborhood. With large mature trees and landscape hedges, it provided excellent cover for the hawk’s attack. Weather data for that day show a low temperature of 18 degrees Fahrenheit and a high temperature of 40 degrees Fahrenheit. There was residual snow cover in some areas, as Lincoln had experienced …
