Niche Partitioning Of Monteverde Warbler Species Based On Differences In Microhabitat And Vertical Stratification, September 2001, Justin Pochman

Monteverde Institute: Tropical Ecology and Conservation

Two congeneric warbler species in Monteverde occupy similar niches and may be competing for resources. The Three-striped Warbler (Basileuterus tristriatus) and the Golden-crowned Warbler (B. culicivorus) are both forest interior species that glean and sally for insects within several meters of the ground. This study looks at foraging preferences in these two species in areas of overlap and non-overlap, which is particularly important in light of recent geographic shifts upslope by the Golden-crowned Warbler (Donnelly 1998; Pounds 1999). The results show that the Three-striped and the Goldencrowned Warbler significantly overlap in both altitude (between 1420 m and 1485 m) and …

Effects Of Plant Size And Flower Color On The Reproductive Success Of Pleurothallis Sanchoi (Orchidaceae), September 2001, Sarah Strozinski

Monteverde Institute: Tropical Ecology and Conservation

Factors contributing to the reproductive success of Pleurothallis sanchoi were examined in relation to plant size and flower color. This particular orchid has plants of varying sizes as well as three color morphs including yellow, purple, and yellow with purple petals. First, the potential for reproductive success was deduced by measuring, on individuals in natural populations, leaf and flower number and how they are related to flower color. Second, the removal and deposition of pollinia on flowers of different colors was examined. It was found that larger plants generally had more flowers, although there appears to be an upper limit …

Long-Billed Hummingbird Specificity To Long Corolla Flowers, September 2001, Laura Anne Kefauver

Monteverde Institute: Tropical Ecology and Conservation

Long-billed hummingbirds prefer long corolla flowers, although structurally they can readily visit short corollas (Feinsinger 1983; Mayzel 1997). This study examined how facultative long-billed hummingbird preferences are to corolla length as well as the role of interference competition. Red and orange plastic tubes of two sizes (short = 2 cm, long = 4 cm) were attached to the holes of eight hummingbird feeders to mimic short and long corollas. A total of 64 thirty-minute observations were made counting visits to "corollas" of different color and length, species, and competitive interactions were also noted. The color of the corolla did not …

Opilionids: Social Behavior As A Defense Mechanism, September 2001, Scott Rosenthal

Monteverde Institute: Tropical Ecology and Conservation

Four environments were created with varying populations of opilionids and experienced hourly mass disturbances to observe if there is a relationship between sex and tibia length in grouping in Monteverde, Costa Rica. The ratio of males to females was five to seven and a significant size difference in tibia among sexes was noticed (T-test male mean = 3.719mm; female mean = 3.382mm, P < 0.0001). Additionally males in groups were significantly larger while females showed no difference (male mean tibia length = 3.678mm (solitary), 3.741mm (group), T-test P = 0.0003; female mean = 3.383mm (solitary), 3.381 mm (group), T-test P = 0.9324). As the amount of disturbance increased, the group size would decrease. Yet the percent of return changed little among varying population sizes. Grouping among opilionids may be used to decrease predation. Their chemical defense will have a stronger effect and they may use individuals as barriers from predators with the competitively superior individuals occupying the center of the group.

The Effects Of Habitat Structural Complexity On Bird Species Richness And Composition, September 2001, Alison Jane Duff

Monteverde Institute: Tropical Ecology and Conservation

With the increasing rate of human activities in tropical regions, it is imperative that we understand the effects of habitat change on biodiversity, and develop appropriate conservation methods. A general trend of increasing bird species richness with increasing habitat structural complexity has been observed by a number of ecologists. The purpose of this study was to test whether this relationship holds for cloud forest bird communities in structurally complex primary forest as compared with simpler secondary forestdominated by Conostegia oerstediana (Melastomataceae). I predicted a strong positive correlation between bird species richness and habitat structural complexity, and bird species compositional differences …

Agricultural Land Use And Butterfly Communities, September 2001, Anne Baptiste

Monteverde Institute: Tropical Ecology and Conservation

Forest habitat in the tropics is being converted at an alarming rate into agricultural lands. The result is loss of global biodiversity at accelerating rates. Butterflies are common indicator species of how biodiversity responds to changing land use. Here butterflies were used to examine the potential impact of different agricultural practices in Monteverde, Costa Rica. Butterflies were trapped in forest, banana, coffee, and pasture. This study found that coffee plantations support significantly greater species diversity (x2 P < 0.005), than banana or pasture. The forest patch was found to support the greatest number of forest dependent species although numbers of these indicator species were comparably high in coffee and banana as well. Forest species were almost absent in pasture and along edge. This suggests that there are crops, which better approximate forest conditions, while drastic land transformations have a large detrimental impact on biodiversity.

Effects Of Climate On Inflorescences Of The Aroid (Araceae) Xanthosoma Sp. And Visitation Rates Of Their Scarab Beetle Pollinators, Cyclocephala Sp., September 2001, Jeffrey Lebrun

Monteverde Institute: Tropical Ecology and Conservation

Spadices of many aroids (Araceae) go through a process known as "thermogenesis", manufacturing heat to attract scarab (Coleoptera) pollinators. In Monteverde, Puntarenas, Costa Rica, Xanthosoma undipes occurs in patches at 1550 meters elevation. Here they attract two scarabs that are thought to be the sole pollinators: Cyclocephala nigerrima and C. sexpunctata. Chances of successful pollination of Xanthosoma have been shown to increase drastically with higher visitation rates of scarabs. Previous studies in Monteverde found no relationship between the temperature of the spathe and beetle visitation (Craig 2001) though taller plants at lower altitudes have been shown to attract more beetles …

A Medicinal Plant Analysis In Premontane Wet/Moist And Premontane Wet Life Zones In Monteverde, Costa Rica, September 2001, Ryan Pjesky

Monteverde Institute: Tropical Ecology and Conservation

This study was completed in Monteverde, Costa Rica on the diversity of medicinal plants in: premontane wet/moist and premontane wet forest. The purpose of this study was to find overall plant diversity and medicinal plant diversity within these two forests. After finding medicinal plant diversity, a conservation value could then be applied for each life zone accordingly. This was done by surveying three, 10-meter square plots in both life zones. It was hypothesized that plant diversities would be different within the two life zones. This hypothesis was not supported: the two plant communities had similar richness (S), diversity (H'), and …

A Comparison Of Moss-Dwelling Invertebrates Along An Altitudinal Gradient, September 2001, Lauren Afsahi

Monteverde Institute: Tropical Ecology and Conservation

Moss abundance and the invertebrates that inhabit moss differ with varying elevations. The purpose of this study was to determine if there was a significant difference in diversity and morphospecies composition of moss-dwelling invertebrates between three different elevations on the Pacific slope (1550 m, 1650 m, and 1750 m) along a tropical wet cloud forest. This study also examined if there was a significant difference between the diversity and morphospecies composition between the Atlantic and the Pacific slopes at an altitude of 1750 m. Eighty-one samples of one morphospecies of moss were collected from trees in a tropical wet cloud …

Resurrecting Transformation For The Post-Industrial Era, Douglas A. Macgregor

Defense Horizons

We must hold our minds alert and receptive to the application of unglimpsed methods and weapons. The next war will be won in the future, not in the past. We must go on, or we will go under.

—General of the Army Douglas A. MacArthur, while serving as Chief of Staff, 1931

The Bush administration took office amid high hopes for the fundamental transformation of the Armed Forces. Yet within months, the problem that transformation was designed to solve—changing a large, expensive Industrial Age structure, especially the Army, into a leaner, more strategically agile Information Age force—receded as more pressing …

Germs Or Rations? Beriberi And The Japanese Labor Experiment In Colonial Fiji And Queensland, Judith A. Bennett

Pacific Studies

In the early 1890s, the Colonial Sugar Refinery Company (CSR) introduced Japanese men to their sugar plantations in Fiji and Queensland because man- agement believed they would prove to be superior workers to other “coloured” labor. In Fiji, an outbreak of beriberi killed many of the Japanese. The medical establishment attributed this to an infective agent, instead of diet, so there was fear the disease could spread. CSR quickly abandoned the costly “experiment” in Fiji. In Queensland, however, the company successfully controlled a beriberi outbreak by altering the rations, though for fear of contaminated food rather than for balanced diet. …

About Art, Baruch Blich

CLCWeb: Comparative Literature and Culture

In his article, "About Art," Baruch Blich investigates why is art -- and especially modern art -- so difficult to understand? Why do art objects raise questions as to their status? Why scrutinizing art involves semiotics, philosophy of language, linguistics, epistemology, ontology, and even metaphysics? Why art is interpreted by psychoanalysis as well as by behaviorism and psychology of perception? What anthropology and sociology have to do with art and why do we witness art debated in the courtroom concerning copyright issues? In short -- what makes art a crossroad for many and sometimes conflicting disciplines? Is there something in …

Does Strength Of Phonological Representations Predict Phonological Awareness In Preschool Children?, Judith G. Foy, Virginia A. Mann

Psychological Science Faculty Works

Previous research has shown a clear relationship between phonological awareness and early reading ability. This article concerns some aspects of spoken language skill that may contribute to the development of phonological awareness, as manifested in rhyme awareness and phoneme awareness. It addresses the hypothesis that phonological awareness abilities are associated with measures that purportedly tap into the strength of phonological representations. We examined rhyme awareness, phoneme awareness, articulatory skill, speech perception, vocabulary, and letter and word knowledge in 40 children, aged 4 to 6, who were just beginning to be exposed to for-mat reading experiences in private preschools. The children …

It Isn't Easy Being Green: Environmental Policy Implications For Foreign Policy, International Law, And Sovereignty, Terry Anderson, J. Bishop Grewell

Chicago Journal of International Law

This paper examines how foreign policy involving trade, defense, diplomacy, and international law is being "greened" at home and abroad as environmental groups pressure government agencies to give environmental concerns greater weight. It argues that these changes represent a fundamental shift in US foreign policy and international relations. It identifies problems that arise from these revisions and explains how free market environmentalism offers a sound alternative that will lead to better environmental protection through freer trade, increased wealth, and decentralization.

The Undersea World Of Foreign Relations Federalism, Edward T. Swaine

Chicago Journal of International Law

Long before 'Judge Wapner's Animal Court," commercial television broadcast a nature series perhaps equally relevant to the law-"The Undersea World of Jacques Cousteau." The show was popular because of what it revealed about a world still mysterious to many of us. It also appealed, however, because it managed to maintain that air of mystery-the sense of a truly distinct world that could not be wholly disclosed, a sense conveyed even more plainly in the tites of Cousteau's Oscar- winning documentaries, "Le Monde du Silence" and "Le Monde sans Soleil." This theme undoubtedly owed a great deal to its narrator: more …

Brussels I: A Race To The Top, Nicole Goldstein

Chicago Journal of International Law

The idea for Brussels I sprang from a concern by European justice ministers that e-commerce was lagging in Europe. The European Commission attributed the dearth of online purchases to consumer fear, an opinion about which they have been very forthright in press statements as well as at the debates over the law. Given that consumer groups in Europe have been pushing for the right to sue companies in the consumer's home country, the EU ministers hope that the elasticity of the new jurisdictional regulation will spur e-commerce by bolstering consumer confidence. Many business owners, however, see Brussels I as a …
