The Ecological Succession Of Birds, Charles C. Adams
Study Of Avian Migration Patterns Using Stable Isotope Analysis In The Galite Archipelago, Tunisia, Hsan Ben Jemaa, Said Nouira, François Fourel, Ilham Bentaleb
Study Of Avian Migration Patterns Using Stable Isotope Analysis In The Galite Archipelago, Tunisia, Hsan Ben Jemaa, Said Nouira, François Fourel, Ilham Bentaleb
Turkish Journal of Zoology
This research employed stable isotope analysis to investigate the migratory patterns and geographic origins of the Eleonora's falcon (Falco eleonorae) and its associated prey species within the Galite Archipelago, Tunisia. Feathers collected from both juvenile and adult falcons, along with their prey, were analysed for deuterium isotopic composition using the "Isorix" package in R, which facilitated the geographic assignment based on stable isotope ratios. The results demonstrated no significant difference in deuterium values (δ2H) between adult and juvenile falcons, indicating a lack of geographical variation in moulting locations among the different age groups. However, the isotopic data for adult falcons …
Dietary Observations Of Adult Pleurodema Nebulosum (Anura: Leptodactylidae) From Argentina, Gabriel Natalio Castillo, Cynthia J. González- Rivas
Dietary Observations Of Adult Pleurodema Nebulosum (Anura: Leptodactylidae) From Argentina, Gabriel Natalio Castillo, Cynthia J. González- Rivas
Turkish Journal of Zoology
This study is the first to examine the diet composition of adult Pleurodema nebulosum specimens based on an analysis of the gastrointestinal contents of 78 individuals. Analyzed herein were 40 specimens from a site disturbed due to anthropogenic action and 38 from a protected area in Argentina. Differences were found in the trophic consumption at both sites. In the protected area, P. nebulosum presented an active foraging mode, with a diet specialized in prey items from the Formicidae family. At the disturbed site, this amphibian showed a sit-and-wait foraging mode, with a generalist diet where it consumes Hemiptera and Coleoptera. …

A Revision Of Hong Kong Harvestmen : Biodiversity, Ecological Preferences And Geographical Distribution, Kai Teck Desmond Tan
A Revision Of Hong Kong Harvestmen : Biodiversity, Ecological Preferences And Geographical Distribution, Kai Teck Desmond Tan
Lingnan Theses (MPhil & PhD)
Opiliones, or harvestmen, is a common animal found throughout the world, there are currently over 6,650 species worldwide but the actual number is estimated to exceed 10,000, making it the third largest order in the class Arachnida. Despite its diversity, it is a rather understudied group. In Hong Kong, there are four described species, but the most recent relevant literature dates back to the at least the early 20th century. This thesis focuses on two common species found in Hong Kong: one previously described species (Heterobiantes geniculatus) and one new species (Pseudoleiobunum lutulentum sp. nov.). I …
From Turf To Turf: Fungal Invasion Of Ascocoryne Turficola In A Northern Michigan Bog, Evan L. Coscarelli-Trott
From Turf To Turf: Fungal Invasion Of Ascocoryne Turficola In A Northern Michigan Bog, Evan L. Coscarelli-Trott
All NMU Master's Theses
This is the first paper to report Ascocoryne turficola Boud. 1905 (Helotiales: Ascomycota) within the United States. It is an obligate bog fungus native to Europe and Siberia, where it is extremely rare across most of its range. A. turficola appeared at Lily Pond Bog in Marquette, Michigan (87.47º W, 46.59º N) in 2019, almost contemporaneous with anecdotal reports in Minnesota and Ontario. Since 2019, the Lily Pond population has exploded and become the dominant fungus in this bog but has yet to spread to similar bogs nearby. This species is adapted to long distance dispersal and carries the potential …
The Influence Of Environmental Change On Genetic Diversity Across Spatial And Taxonomic Scales, Connor M. French
The Influence Of Environmental Change On Genetic Diversity Across Spatial And Taxonomic Scales, Connor M. French
Dissertations, Theses, and Capstone Projects
The spatial distribution of genetic diversity is of interest to biodiversity scientists and conservationists and is a fundamental metric of biodiversity. Genetic diversity patterns across spatial and taxonomic scales contain information about population and assemblage dynamics that can convey their resilience to environmental change. Ectotherms are especially linked to their environments and may be especially sensitive to fluctuations in the environment over time. Herein, I investigate global and regional patterns of genetic diversity in two groups of ectotherms, insects and lizards, to understand the relationship between environmental change and genetic diversity, from populations to assemblages. Overall, my research aims to …
Scale-Dependent Population Drivers Inform Avian Management In A Declining Saline Lake Ecosystem, Aimee M. Van Tatenhove, John Neill, Russell E. Norvell, Erica F. Stuber, Clark S. Rushing
Scale-Dependent Population Drivers Inform Avian Management In A Declining Saline Lake Ecosystem, Aimee M. Van Tatenhove, John Neill, Russell E. Norvell, Erica F. Stuber, Clark S. Rushing
Wildland Resources Faculty Publications
Shrinking saline lakes provide irreplaceable habitat for waterbird species globally. Disentangling the effects of wetland habitat loss from other drivers of waterbird population dynamics is critical for protecting these species in the face of unprecedented changes to saline lake ecosystems, ideally through decision-making frameworks that identify effective management options and their potential outcomes. Here, we develop a framework to assess the effects of hypothesized population drivers and identify potential future outcomes of plausible management scenarios on a saline lake-reliant waterbird species. We use 36 years of monitoring data to quantify the effects of environmental conditions on the population size of …
Soil Biogeochemical Properties Remain Altered Following Cessation Of Long-Term Simulated Nitrogen Deposition In A Temperate Forest, Jennie Ellen Wuest
Soil Biogeochemical Properties Remain Altered Following Cessation Of Long-Term Simulated Nitrogen Deposition In A Temperate Forest, Jennie Ellen Wuest
Master's Theses and Capstones
Nitrogen (N) is an essential nutrient in terrestrial ecosystems and the transformations it undergoes mediated by microbes in soil are central to N cycling. While rates of atmospheric N deposition due to anthropogenic activity increased dramatically with the industrial revolution, government regulations in the late 20th century resulted in a reversal. Rates of atmospheric N deposition remain well above pre-industrial levels, but the last two decades have seen a steady decrease in areas such as the Northeastern United States. To investigate the potential for soil recovery from long-term N addition, we measured a suite of soil biogeochemical properties in a …

Association Of Self-Reported Disease Severity With Depression And Anxiety Among Copd Patients, Yousef Saad Aldabayan, Antonieto Alaban, Eduardo Fabella, Amal Ismael Abdelhameed
Makara Journal of Health Research
Background: This study was conducted to estimate the proportion of patients who experience a high impact from chronic obstructive pulmonary disease (COPD) on their health status and those who also experience symptoms of depression and anxiety. It also sought to determine whether the health impact of the disease is associated with anxiety and depression.
Methods: An analytical cross-sectional study was conducted among 177 randomly selected patients with COPD seeking treatment in various primary health centers in Al Ahsa, Saudi Arabia. The COPD Assessment Test (CAT) was used to determine the impact of COPD on health generally, and the …
