He Effects Of Climate Change On Native Icelandic Plants: A Morphometric Analysis, Maia Jones
He Effects Of Climate Change On Native Icelandic Plants: A Morphometric Analysis, Maia Jones
Independent Study Project (ISP) Collection
This study seeks to evaluate the morphology of three native Icelandic plant species, Alchemilla alpina, Arabidopsis petraea, and Silene uniflora, in order to determine if changing climatic conditions have had an effect on Icelandic vegetation during the twentieth century. I measured herbarium specimens collected during a time period before 1950, and during the period from the late 1960s to the present. Using traditional morphometrics methods, I searched for changes in morphological traits such as plant height, leaf length to width ratio, and leaf size, then performed two-tailed t-tests to analyze the results of the analyses. I found significant changes …
The Taxonomy, Reproduction, And Distribution Of Rare Plants: A Study Of Magnolia Sp. In The Río Zuñac Reserve, Ecuador, Alyssa Kullberg
The Taxonomy, Reproduction, And Distribution Of Rare Plants: A Study Of Magnolia Sp. In The Río Zuñac Reserve, Ecuador, Alyssa Kullberg
Independent Study Project (ISP) Collection
Ecuadorian cloud forests are biodiversity hotspots and centers of unprecedented levels of endemism, but they are also under-researched and under-protected. This study took place in the Río Zuñac Reserve, which is a reserve of about 850 ha located in the Tungurahua province of Ecuador, and is home to at least 20 endemic plant species. Three new species of Magnolia have been discovered in this reserve in the past five years: Magnolia llanganates, Magnolia vargasiana, and one species that has yet to be formally described. This study dealt with accurately locating and describing new individuals of these species over the …
Surveying The Distributions Of Melaleuca Quinquenervia, Psidium Cattleianum, And Litsea Glutinosa At Analalava Special Reserve, Hanusia Higgins
Surveying The Distributions Of Melaleuca Quinquenervia, Psidium Cattleianum, And Litsea Glutinosa At Analalava Special Reserve, Hanusia Higgins
Independent Study Project (ISP) Collection
This study surveyed the distributions of three invasive plant species, Melaleuca quinquenervia, Psidium cattleianum, and Litsea glutinosa at the Analalava Special Reserve in Mahavelona, Madagascar. Analalava is a 229-hectare degraded patch of low-elevation humid forest on the northeast coast of Madagascar, and one of the last forest fragments remaining in the region. It is a haven for biodiversity, containing 343 recorded species of plants, 12 of which are locally endemic. Invasive species are considered the second-most significant threat to biodiversity, both worldwide and specifically at Analalava. Based on a systematic transect survey of these three targeted invasive species, their distributions …
Investigation De Regeneración Natural De Plantas Vasculares En La Reserva Madrigal Del Podocarpus / Investigation Of Natural Regeneration Of Vascular Plants In The Madrigal Reserve Of The Podocarpus, Sy Baker
Independent Study Project (ISP) Collection
En el Sur de Ecuador, hay una historia larga de incendio que está asociada con la historia de la agricultura y ganadería a causa de las técnicas de tala y quema para despejar áreas para campos y también quemaduras intencionales para fertilizar los suelos y mejorar productividad agrícola (Fernandez et al 2015). En los últimos días de Noviembre de 2016, un incendio quemó campos, la Reserva Madrigal de Podocarpus, y parte del Parque Nacional Podocarpus en Loja, Ecuador—el enfoque de este estudio. En este estudio: (1) se registraron las especies y distribución de plantas pioneras y sobrevivientes, (2) la se …
Soil Total Organic Carbon And Farmers’ Perceptions Associated With Bokashi Application In Cerro Punta, Panama, Emma Searson
Soil Total Organic Carbon And Farmers’ Perceptions Associated With Bokashi Application In Cerro Punta, Panama, Emma Searson
Independent Study Project (ISP) Collection
Sustainable use and maintenance of agricultural soils are important for maintaining long-term agricultural productivity and environmental quality. These issues are especially important in Cerro Punta, known as the breadbasket of Panama, which is experiencing severe erosion. While current practices and agrochemical usage damage soil health and function over time, application of organic material improves soil physic-chemical properties such as nutrient and total organic carbon (TOC) content. Bokashi, a fermented organic soil amendment with effective microorganisms (EM), is thought to be especially beneficial due to its ability to augment populations of soil microbes, which deliver plant-available nutrients to crops and improve …
Comparing Avian Diversity And Anthropogenic Disturbance At Sendero Los Quetzales Cerro Punta, Panamá, Sloane Merdinger
Comparing Avian Diversity And Anthropogenic Disturbance At Sendero Los Quetzales Cerro Punta, Panamá, Sloane Merdinger
Independent Study Project (ISP) Collection
This report summarizes the survey of land and avian diversity along a transect that runs from the exterior to the interior of the Los Quetzales Trail of Parque Nacional Volcán Barú in Cerro Punta, Chiriquí, Panamá. The region of Cerro Punta is Panamá’s primary producer of produce and also home to one of the most biodiverse land reserves in the world. Despite protection efforts the area is continuously threatened by human development. The study juxtaposes calculated Shannon-Wiener Biodiversity Indices across graduated levels of anthropogenic disturbance to determine if there is a significant difference in biodiversity between areas with low, intermediate, …
