Animal Conservation In St. Louis, Kate O'Sullivan Jan 2024

Animal Conservation In St. Louis, Kate O'Sullivan

Undergraduate Research Symposium

St. Louis has a multitude of organizations involved in the natural sciences. But how many of them actually contribute towards animal conservation? The St. Louis Zoo is an organization that focuses a lot of its effort on presentation, so how does that impact the funds that go towards actually saving the animals? I plan to dive into the different animal-based organizations in St. Louis and its surrounding areas, as well as discuss the positives and negatives of each organization. Furthermore, I will provide examples from several sources that I have been reviewing all year to support my claims. I plan …


Critical Corridor: Survey Of Predator Occurrence And Habitat Use In A Threatened Rainforest Protected Area: Comatsa-Sud And Marojejy National Park, Madagascar, Patrick H. Ross Jun 2022

Critical Corridor: Survey Of Predator Occurrence And Habitat Use In A Threatened Rainforest Protected Area: Comatsa-Sud And Marojejy National Park, Madagascar, Patrick H. Ross

Theses

Madagascar is a nation praised for its floral and faunal endemism and biodiversity. Among the island nation’s most emblematic fauna are its native mammalian carnivores; they are members of the threatened and endemic Eupleridae family. The Corridor of Marojejy – Anjanaharibe Sud – Tsaratanana (COMATSA) is a system of forest protected areas in which three large protected areas are connected in northern Madagascar: Tsaratanana Reserve, Anjanaharibe Sud Special Reserve and Marojejy National Park which is also a UNESCO World Heritage site. COMATSA is a newly protected and currently threatened corridor system that lacks detailed surveys and assessments of its native …

Interactions And Pathogen Transmission Between Carnivores In Madagascar, Fidisoa Rasambainarivo Apr 2018

Interactions And Pathogen Transmission Between Carnivores In Madagascar, Fidisoa Rasambainarivo

Dissertations

Introduced carnivores exert considerable pressure on native predators through predation, competition and disease transmission. Improved understanding of determinant factors of interactions and pathogen transmission between introduced and endemic wildlife may help to predict disease emergence, avoid pathogen spillover and help control outbreaks. Using non-invasive camera traps, I identified areas where transmission of pathogens might happen through records of shared space-use within a protected area in Eastern Madagascar. I showed that indirect interactions between animals were more likely to occur near the research station which may constitute a disease transmission hotspot for carnivores in the landscape. Secondly, I investigated the associations …


110 Years Of Avipoxvirus In The Galapagos Islands, Patricia Parker, Elizabeth Buckles, Heather Farrington, Kenneth Petren, Noah Whiteman, Robert Ricklefs, Jennifer Bollmer, Gustavo Jiménez-Uzcátegui Jan 2011

110 Years Of Avipoxvirus In The Galapagos Islands, Patricia Parker, Elizabeth Buckles, Heather Farrington, Kenneth Petren, Noah Whiteman, Robert Ricklefs, Jennifer Bollmer, Gustavo Jiménez-Uzcátegui

Biology Department Faculty Works

The role of disease in regulating populations is controversial, partly owing to the absence of good disease records in historic wildlife populations. We examined birds collected in the Galapagos Islands between 1891 and 1906 that are currently held at the California Academy of Sciences and the Zoologisches Staatssammlung Muenchen, including 3973 specimens representing species from two well-studied families of endemic passerine birds: finches and mockingbirds. Beginning with samples collected in 1899, we observed cutaneous lesions consistent with Avipoxvirus on 226 (6.3%) specimens. Histopathology and viral genotyping of 59 candidate tissue samples from six islands showed that 21 (35.6%) were positive …


Tapeinosperma Alatum (Myrsinaceae): A Remarkable New Species From Ceram, Diane Holland, P.F. Stevens Jan 1998

Tapeinosperma Alatum (Myrsinaceae): A Remarkable New Species From Ceram, Diane Holland, P.F. Stevens

Biology Department Faculty Works

A new pachycaul species Tapeinosperma alatum D.E. Holland & P.F. Stevens (Myrsinaceae) is described from South Central Ceram. It is characterized by its huge leaves, over 1 m long, and congested, almost Gunnera-like. inflorescence. The distinctive distribution of the Papuasian pachycaul species of Tapeinosperma is briefly compared with that of a number of other unrelated taxa.


An Analysis Of The Variation Within Cratoxylum Arborescens (Clusiaceae) In Malesia, A.C. Church, P.F. Stevens Jan 1997

An Analysis Of The Variation Within Cratoxylum Arborescens (Clusiaceae) In Malesia, A.C. Church, P.F. Stevens

Biology Department Faculty Works

The variation within the widespread West Malesian species Cratoxylum arborescens (Vahl) Blume was analyzed and three distinctive variants were found. These are recognized formally as varieties, var. arborescens, var. miquelii King, and var. borneense A.C. Church & P.F. Stevens. A key and full descriptions are given. The characters employed to delimit the three taxa are discussed and the selection of varietal rank is justified.
