Flowers And Feeders: A Comparison Of Hummingbird Feeding Activity, Caitlin A. Mchugh
Flowers And Feeders: A Comparison Of Hummingbird Feeding Activity, Caitlin A. Mchugh
Independent Study Project (ISP) Collection
Hummingbird feeders are the best way to see high species abundance and diversity, but few studies examine the differences in species abundance, diversity, feeding patterns, and aggression between flowering plants and artificial feeder sites within the same habitat. Are there significant affects on local hummingbird ecology by the presence of feeders? This paper explores possible answers to this question by investigating discrepancies between the two types of site and the implications of said discrepancies. A high count method was used to estimate species abundance and diversity along with qualitative observation was used to analyze aggression. The study found that, in …
Estatus Actual De Los Búhos Terrestres (Athene Cunicularia) En La Zona De Puerto López, Ecuador: Efectos De Las Creencias Y Sentimientos Hacía Los Animales Silvestres, Allison Qubain
Independent Study Project (ISP) Collection
In response to negative attitudes towards the existing biodiversity in the region of Puerto Lopez, Ecuador and as a follow-up of a study conducted in 2006 on the status of Burrowing Owl (Athene cunicularia) populations, through informal interviews and observation, this investigation focuses on how local sentiments towards nature have affected the current status of the Burrowing Owl populations and their habitat. The investigation revealed that in addition to the effects of legends and beliefs, there is an existing lack of knowledge, understanding, and appreciation for the extremely high biodiversity, which has created an evident fear instilled in the people. …
Food Item Coloration Of The Common Squirrel Monkey (Saimiri Sciureus): An Analysis Of Color Vision Polymorphism At The Tiputini Biodiversity Station, Stefan Cooper Rosin
Food Item Coloration Of The Common Squirrel Monkey (Saimiri Sciureus): An Analysis Of Color Vision Polymorphism At The Tiputini Biodiversity Station, Stefan Cooper Rosin
Independent Study Project (ISP) Collection
Though the genetic and physiological aspects of primate color vision are understood, knowledge of the history and advantage of such an adaptation is currently limited to speculation. It appears that trichromatic color vision arose as a foraging specialization, though there is reason to believe dichromacy, or red-green color blindness, provides unique advantages as well. This study examines the coloration of food items of the common squirrel monkey (Saimiri sciureus) at the Tiputini Biodiversity Station, Yasuni National Park “buffer zone,” Ecuador. Saimiri is known to be polymorphic with respect to color vision, exhibiting both di- and trichromacy. With the goal of …
Playback Experiments Using Regional Duets And Solos: Territoriality In The Grey-Breasted Wood Wren In Eastern Andean Ecuador, Arathi Govind
Playback Experiments Using Regional Duets And Solos: Territoriality In The Grey-Breasted Wood Wren In Eastern Andean Ecuador, Arathi Govind
Independent Study Project (ISP) Collection
In this study, playback experiments were conducted on the Grey-breasted Wood Wren, H. leucophrys, at Yanayacu Biological Research Station and Center for Creative Studies in Ecuador. This study was conducted in order to see how reactive the birds were towards duets from the area, solos from the area, and duets from other regions of the country. Pairs were expected to react more strongly towards duets than solos and familiar duets stronger than unfamiliar ones. Two different playback experiments were conducted. In the first experiment, six different pairs were chosen along with four different song types, a Yanayacu duet, a male …
