Equitable Self-Ownership For Animals, David Favre

Duke Law Journal

This Article proposes a new use of existing property law concepts to change the juristic personhood status of animals. Presently, animals are classified as personal property, which gives them no status or standing in the legal system for the protection or promotion of their interests. Professor Favre suggest that it is possible and appropriate to divide living property into its legal and equitable components, and then to transfer the equitable title of an animal from the legal title holder to the animal herself. This would create a new, limited form of self-ownership in an animal, an equitably self-owned animal. Such …

Assortative Mating Of The Halloween Butterfly Dryadula Phaetusa (Nymphalidae, Heliconiinae), November 2000, Darin Reynaud

Monteverde Institute: Tropical Ecology and Conservation

Possible size-assortative mating was investigated in a captive population of the butterfly, Dryadula phaetusa (Nymphalidae) by comparing the forewing sizes of individuals of mating pairs to the average size of forewings in the whole population. It was postulated that females would prefer larger males because they deposit larger spermatophores, and females would thereby increase their fitness. Males would also prefer larger females because larger females have a better chance of fighting off predators and thus higher fitness. Individuals that were feeding or courting were also measured to document size variation and investigate size-dependent behaviors. There was no evidence for positive …

Diversity, Abundance, Richness, And Composition Of Avian Communities And Avian Foraging Behavior At Ficus Pertusa, November 2000, Heather Whelpley

Monteverde Institute: Tropical Ecology and Conservation

This study investigated differences in success between fruiting Ficus pertusa trees in a single pasture in Monteverde, Costa Rica. Success was qualitatively measured by the abundance, richness and diversity of avian dispersers and the total number of seeds dispersed (as measured by the number of visits by birds that swallow fruits). Each of the four sites was observed for five days from 7:00am – 11:00 am. Significant differences in diversity were found in five of seven comparisons between the sites, but neither diversity nor number of bird visits was related to dbh or crop size of the tree. Significant differences …

Effects Of Microhabitat On Morphological Adaptations Of Pleurothallis Sanchoi (Orchidaceae), November 2000, B. J. Labay

Monteverde Institute: Tropical Ecology and Conservation

An abiotic gradient of wind, moisture and sun across a tree may directly affect morphological traits adapted for water conservation. In this study, Pleurothallis sanchoi was examined in a pasture near the Estación Biológica Monteverde, Costa Rica. I looked at how microhabitats affect morphological adaptations, including leaf thickness, toughness and stomata density. I tested two predictions of my hypothesis that individuals living in harsher conditions would show more adaptations for water conservation. The first is that individuals in a abiotic gradient along a tree will show variance in water conservation adaptations. The second is that in two distinct habitats, full …

The Influence Of Leaf Shape Of Passiflora Biflora In Heliconius Spp. Butterfly Oviposition, November 2000, Sarah M. Dempsey

Monteverde Institute: Tropical Ecology and Conservation

Between species the leaf morphology of Passiflora (Passifloraceae) differ greatly in leaf shape. These differences may be attributed to the presence of Heliconius larvae, who feed exclusively on Passiflora. Adult females may use leaf shape as an oviposition cue, thus the importance of the changing leaf morphology. This study was conducted in an enclosure in the Monteverde Butterfly Garden where I studied three species of Heliconius butterflies: Heliconius hecale, H. charitonius and H. erato. I studied the oviposition behavior on Passiflora biflora due to the varying leaf shapes present, which are two and three lobed leaves. Egg placement showed that …

Pollinia Removal And Visitation In Epidendrum Radicans (Orchidaceae) And Asclepias Curassavica (Asclepiadaceae), November 2000, Nicholas J. Deacon

Monteverde Institute: Tropical Ecology and Conservation

The possibility of a floral mimicry complex between Lantana camara, Asclepias curassavica, and Epidendrum radicans sounds appealing based on their similarity in flower color and overlapping ranges in Central America. The pollinia removal in E. radicans and A. curassavica was observed under different conditions of scale and proximity. The conditions for increased pollinia removal in E. radicans are to have a large inflorescence, close proximity to A. curassavica or L. camara in a patch, isolation from other E. radicans, occurrence in less dense patches, and avoidance of patches that contain L. camara. Asclepias curassavica benefits when alone more than when …

Preferred Sucrose Concentration In Nectarivorous Bats, November 2000, Jeremy C. Sullivan

Monteverde Institute: Tropical Ecology and Conservation

Pollinators and plants are involved in a mutualism, where pollination takes place in exchange for some payment, usually in the form of nectar. One might assume that these nectar rewards would closely match a pollinator’s preference, but flowers may conserve energy by offering an unfavorable, but still suitable nectar reward. Bat pollinated flowers have been found to offer nectar of an 18% sucrose concentration, on average, over a range of 3%-51% (Baker 1998). Where in this range of sucrose concentrations do bat preferences lie? To find out, sucrose concentration preferences of a community of Neotropical bats were studied at the …

Sugar Preferences Of Nectarivorous Bats, November 2000, Kristina L. Keppel

Monteverde Institute: Tropical Ecology and Conservation

Groups of flowers pollinated by the same subset of species will have general characteristics in common. These characteristics, when considered together, are called flower syndromes. For example, flowers that are bat pollinated open at night and are often drab, pale, and green with a musty odor, and contain hexose-rich nectar. Baker and Baker (1983) findings demonstrate that all bat-pollinated flowers have hexose-rich or hexose-dominated nectar. Four feeders were hung outside of the Hummingbird Gallery in the Monteverde Reserve. Each feeder contained a different type of sugar solution: one of fructose, one of glucose, the third of honey (a mixture of …

Crystallization And Preliminary X-Ray Diffraction Studies On The Dna-Binding Domain Of The Multidrug Transporter Activation Protein (Mtan) From Bacillus Subtilis, M. H. Godsey, N. N. Baranova, A. A. Neyfakh, R. G. Brennan

CUP Faculty Research

The N-terminal DNA-binding domain of the multidrug transporter activation protein (MtaN) was crystallized by the hanging-drop vapour-diffusion method using lithium chloride as a precipitant. The crystals are orthorhombic and belong to the space group I2₁2₁2₁, with unit-cell parameters a = 49.4, b = 67.8, c = 115.0 Å. Diffraction data have been collected at 100 K to 2.75 Å resolution at a synchrotron-radiation source.

Curriculum And Assessment : A Question Of Politics?, Christine R. Brew, Gilah C. Leder

Australian Journal of Teacher Education

The Victorian Certificate of Education (VCE) has been subject to ongoing modifications since its full introduction in 1992. These changes were largely driven by vocal opponents of this educational reform. In this paper we give voice to teachers charged with implementing the curriculum and assessment directives of the VCE. Specifically, we draw on the experiences of close to 500 senior mathematics teachers – through interview and survey data - to consider the impact on them of the evolution of the VCE.

Adaptive Response Of Scaphyglottis Acostaei (Orchidaceae) To Microhabitat Variability, November 2000, Andrew Fisher

Monteverde Institute: Tropical Ecology and Conservation

Orchids exhibit many adaptations, including pseudobulbs which store water and root velamen, which assists in water uptake, to deal with the harsh, water stressed conditions that are an integral part of epiphytic life. Within a single host tree the intensity of water stress varies between microhabitats caused by presence of moss and bark fissures to reduce evaporation of water, and positions that increase or decrease exposure to wind, precipitation and sun. The orchid, Scaphyglottis acostaei exhibits variable pseudobulb sizes and water holding potential of velamen, possibly as a result of different levels of water stress and water availability. In this …

Acidic Environments Within Tank Bromeliads And Its Effect On Microorganism Community Richness, November 2000, Jennifer Wade

Monteverde Institute: Tropical Ecology and Conservation

Elfin forest tank bromeliads were shown to have lower pH when positioned below mats of epiphytic bryophyte than in open gaps. The effect of lower pH was studied to see if it influenced microorganism community abundance, species richness, evenness and diversity. It was found that increasing levels of pH over a range of 4.3 – 5.8, increased population sizes of most microorganisms. In fact abundance of individuals in the entire community spanned over an order of magnitude (82- 1936 individuals). Species richness also increased with pH but only as a function of increased abundance of individuals. One species richness was …
