Bryophyta Sensu Stricto Presence And Function In The Epiphytic Ecosystems Of The Tropical Montane Cloud Forests Of El Valle De Anton, Teaghan Duff Oct 2023

Bryophyta Sensu Stricto Presence And Function In The Epiphytic Ecosystems Of The Tropical Montane Cloud Forests Of El Valle De Anton, Teaghan Duff

Independent Study Project (ISP) Collection

Bryophyta sensu stricto, colloquially known as moss, is often found growing epiphytically in cloud forest ecosystems. Under these conditions, moss may fulfill a secondary foundational species (FS) role, supporting increased habitat for other organisms while remaining dependent on the primary FS host tree. Exploring the dual relationship of moss as both a dependent and supportive organism allows for better understanding of its connective role within ecosystems. Research in the cloud forests of El Valle de Anton focused on relative abundance, environmental surroundings, morphology, and microclimate of mosses to offer baseline data on these connections. Mosses along four different trails within …


Bryophyte (Sl) Growth And Environmental Factors Along An Altitudinal Gradient On Cerro Gaital, El Valle, Coclé, Panamá, Julian Grace-Martin Oct 2023

Bryophyte (Sl) Growth And Environmental Factors Along An Altitudinal Gradient On Cerro Gaital, El Valle, Coclé, Panamá, Julian Grace-Martin

Independent Study Project (ISP) Collection

Research on bryophytes (SL) in the tropics has been lacking compared with the high number of species found there and the potential benefit of bryophytes (SL) as indicators of pollutants and other forms of human disturbance. This study investigated whether or not bryophyte (SL) growth patterns showed relation when compared with environmental factors on the mountain Cerro Gaital in El Valley, Panamá. Whether or not bryophytes (SL) are present, extent of the area covered by their growth, and height of their growth are all aspects of bryophyte (SL) growth that were used. In this study, these three aspects are compared …


Understory Epiphyte Hydrology: Analyzing Water Storage Capacity Of Epiphytes Along An Elevational Gradient In Western Ecuadorian Cloud Forest, Angelina Dodge Apr 2023

Understory Epiphyte Hydrology: Analyzing Water Storage Capacity Of Epiphytes Along An Elevational Gradient In Western Ecuadorian Cloud Forest, Angelina Dodge

Independent Study Project (ISP) Collection

Epiphytes are defined as plants that grow on a host, often another plant, and acquire their nutrients and water from the atmosphere. As such is true, epiphyte composition is largely dependent upon atmospheric and thus climactic conditions. Due to high levels of atmospheric water availability that results from the frequent presence of mist, clouds, and high humidity, epiphytic plants grow and thus store water within the above ground region of the Andean cloud forest at levels higher than in any other ecosystem found in Ecuador. This study was done in hopes of revealing any trends of epiphytic water storage capacity …


A Comparative Plague Study Of Cacao Fungal Disease In Cacao Pods Within Monocultures And Indigenous Agroforests In Ecuador’S Napo Province, Seamus Mccarthy Apr 2023

A Comparative Plague Study Of Cacao Fungal Disease In Cacao Pods Within Monocultures And Indigenous Agroforests In Ecuador’S Napo Province, Seamus Mccarthy

Independent Study Project (ISP) Collection

This study analyzes the composition of three major fungal diseases in Theobroma cacao fruits compared between monocultures and chakra agroforests in the Napo province of Ecuador with the goal of noting similarities and differences in the disease composition between the two systems, as well as investigate possible variation within this poorly understood category of agroforest to better structure future studies. Cacao pods on sampled trees were counted and fungal infections identified visually and by touch. Chakra systems were selected in the communities of Cinco de Enero and Seis de Marzo to the Southwest of Tena, Ecuador. Monoculture data was collected …


Mycorrhizal Fungi And Reforestation In An Eastern Lowland Rainforest Of Madagascar, Sophia Gibby Apr 2023

Mycorrhizal Fungi And Reforestation In An Eastern Lowland Rainforest Of Madagascar, Sophia Gibby

Independent Study Project (ISP) Collection

Most terrestrial plants worldwide make associations with mycorrhizal fungi, yet the fungal diversity of Madagascar is vastly unknown. This research project is a preliminary investigation into the mycorrhizal status of 19 tree species in and near Ranomafana National Park (RNP), a lowland tropical forest on the southeast coast of Madagascar. Arbuscular mycorrhizal (AM) colonization in these species was studied in root samples under the microscope in the laboratory of Centre ValBio (CVB). The degree of AM infection was assessed for three study areas: one directly adjacent to a protected area and two reforestation sites supported by CVB. For the 19 …
