Data Repository For "Use Of Redwood Basal Hollows By Bats: A Focus On The Townsend’S Big-Eared Bat On The North Coast Of California", Amon J. Armstrong

Research Data Sets

Loss of roosting resources, either through disturbance or removal, negatively affects bats. Identifying sensitive species and determining roost requirements are critical components in conserving their habitat. Cavity roosting bats on the North Coast of California are known to use hollows in large redwood trees. In this study, we examined the factors determining the use of basal tree hollows by different bat species at eight redwood forest sites in Del Norte, Humboldt, and Mendocino Counties, California. Bat guano was collected from 179 basal hollow roosts from 2017 to 2018, and guano mass was used as an index of roosting activity. Nine …

Possible new species, future potential discoveries as well as current significance in terms of conservation are discussed.

Extending Coverage Of Specialized Metabolism In Plant Metabolic Reconstructions, Tristan Contant

Summer Research

• The goal was to extend the coverage of PlantSEED by including more secondary metabolic pathways.
• This involves adopting a more integrative approach that shows regard for the lack of conservation of catalytic domains and the condition-specific considerations for specialized metabolite synthesis.

Stormwater Capture Via Green Infrastructure In The Plaster Creek Watershed, Josian Aardema, Dat Cao, Saul Miranda, Jose Munoz, Daniel Kim, Simon Kok, Delaney Sall, Deanna Geelhoed, David Warners

Summer Research

Calvin University’s campus is located within the Plaster Creek watershed, an area of land that extends from Caledonia to the Grand River near downtown Grand Rapids. All of the water within this region drains into Plaster Creek, which, after many years of neglect and mistreatment, has become one of the most polluted waterways in West Michigan. Plaster Creek Stewards (PCS) aims to restore the local watershed by means of education, research and “on the ground” restoration. The focus of their restoration work is to reduce stormwater runoff containing high amounts of sediment, chemicals, and other pollutants. A variety of green …

Jaguars And Pumas Exhibit Distinct Spatiotemporal Responses To Human Disturbances In Colombia’S Most Imperiled Ecoregion, Joe J. Figel, Sebastián Botero-Cañola, Juan David Sánchez-Londoño, Javier Racero-Casarrubia

University of Nebraska State Museum: Mammalogy Papers

Abstract

Coexistence of sympatric felids is facilitated by mutual avoidance and the partitioning of habitats, prey, and time. Anthropogenic disturbances disrupt this coexistence in fragmented landscapes, potentially triggering cascading influences in ecological communities. We used photographic data from 8,717 trap nights (November 2014–June 2016) at 87 camera trap sites in Colombia’s middle Magdalena River basin to compare spatiotemporal overlap among jaguars (Panthera onca), pumas (Puma concolor), their prey, and humans, at sites of high and low disturbance, as determined by the human influence index. Human disturbance events (e.g. domestic dogs, livestock, and humans, including armed hunters) …

Biodiversity Of Small Mammals And Paleoenvironment Of Transbaikalia And North Mongolia In The Late Pliocene, N. V. Alexeeva, M. A. Erbajeva

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

This paper reports the results of analysis on small mammal faunas dwelling during the Late Pliocene the Transbaikal and Northern Mongolia regions. They were found to share many common species, even though some differences linked with local and regional specifics of the environment are the case. High diversity of small mammal taxa, species richness and their prominent quantity specify the localities of Udunga, Beregovaya and Tologoi in Transbaikal region and in Shamar of Northern Mongolia. The compositions of all faunas point to the existence of the savanna-like landscapes and warm semiarid climate in that period.

Hypsugo Stubbei Sp. Nov., A Novel Cryptic Bat Species Of The Genus Hypsugo (Vespertilionidae, Chiroptera, Mammalia) From Mongolia, Dietrich Dolch, Nyamsuren Batsaikhan, Annegret Stubbe, Dirk Steinhauser

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The occurrence of two members of the genus Hypsugo, namely H. alaschanicus and H. savii caucasicus, have been reported for Mongolia in the literature. Due to various taxonomic reassignments within and between genera, the number of records for the genus Hypsugo in Mongolia is quite scarce and sometimes not resolved at species or subspecies level. Despite recognition of the two above-mentioned species, recent reports based on genetic analyses describe only new and further records of H. alaschanicus. Thus, it exists a large uncertainty regarding the occurrence and distribution of H. savii caucasicus in Mongolia. Here, our efforts …

Zur Molekularen Klassifizierung Der Mongolischen Kormorane Phalacrocorax Carbo (Linnaeus, 1758), Lucie Marie Baltz, Michael Stubbe, Davaa Lchagvasuren, Lara-Sophie Dey

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The cormorant Phalacrocorax carbo (Linnaeus, 1758) is a common breeding species at lake areas of Mongolia. Although molecular research has been conducted on many colonies worldwide, no studies of the genetic diversity of Mongolian colonies are known to date. In this study, we sequence for the first time a fragment of cytochrome oxidase 1 (CO1) from ten individuals of the 2017 resident population at Telmen-nuur. Here we perform molecular identification and analyze it in the context of existing data from populations studied worldwide. A clear assignment to the species P. carbo could be shown, but no identification on subspecies level …

Phylogenie, Morphologie Und Ökologie Mongolischer Langohrfledermäuse Der Gattung Plecotus (Mammalia, Chiroptera, Vespertilionidae), Dietrich Dolch, Bernd Gärtner, Klaus Thiele, Dirk Steinhauser, Ariunbold Jargalsaikhan, Annegret Stubbe, Nyamsuren Batsajchan, Davaa Lchagvasuren

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The Palaearctic is a zoogeographical region where knowledge of the distribution, taxonomy and ecology of bats (Chiroptera) is generally quite extensive. However, for many Palaearctic subregions, including Mongolia, detailed knowledge is still quite scarce. Also for some groups of species there are only few studies available to date. This holds also true for the long-eared bats of the genus Plecotus. For the long-eared bats, which live in close family groups and do not migrate over long distances, the development of different life form types can be expected. Studies tackling this are so far lacking.

The fundamental revision of the …

Using Audio Recording Devices And Multiseason Occupancy Modelling To Evaluate Clark's Nutcracker (Nucifraga Columbiana) Occurrence In Whitebark Pine Habitats Of Washington's Cascade Mountains, Lauren Taracka

Undergraduate Honors Theses

The Clark’s nutcracker (Nucifraga columbiana) and whitebark pine (Pinus albicaulis), both native to the harsh subalpine habitats of Washington’s Cascade Mountains, are being negatively impacted by white pine blister rust (Cronartium ribicola), the mountain pine beetle (Dendroctonus ponderosae), and climate change. As temperatures continue to warm, while many species at lower elevations can move upward in elevation to suit their temperature needs, subalpine species do not have that option. Whitebark pine is a keystone tree species - numerous animals consume its high fat, high energy seeds; it’s a nurse tree, providing shelter …

Investigation Of Fluorescence In Selected Mammals Of Arkansas, C. Renn Tumlison, Terry L. Tumlison

Journal of the Arkansas Academy of Science

The adaptive value of fluorescence among the vertebrates has been studied most in fishes and birds, and only a few observations have been published regarding fluorescence in the pelage of mammals. Recently, reports of fluorescence in some marsupials, the platypus, and in flying squirrels have become available. We report the occurrence of fluorescent properties in some mammals from Arkansas. Most carnivores, bats, and rodents did not exhibit the property when viewed under UV light. However, opossums, rabbits, a weasel, muskrats, and moles showed substantial UV response, and a few other mammals showed minor fluorescence. Colors fluoresced included pink, green, and …

Distribution And History Of The Roseate Spoonbill (Platalea Ajaja) In Arkansas, C. Renn Tumlison, Grace Wills, Karen Rowe

Journal of the Arkansas Academy of Science

The Roseatte Spoonbill (Platalea ajaja) is a rare bird in Arkansas and was not reported from the state until 1959, when it was seen in southwestern Arkansas. By use of online sources for citizen science, we elucidate the history of occurrence and present analysis of seasonal distribution of this bird in Arkansas. Individuals arrive in Arkansas as early as April, observations peak in August, and the birds may remain to late October when colder weather promotes southward migration. Most observations are of a few birds, but a maximum of 128 has been counted at one location and time. …

Bird Usage Of Black Marasmius Fibers As Nest Material, Haris Rana, Shayla Smithson, Jack Jackson, Ragupathy Kannan

Journal of the Arkansas Academy of Science

Black Marasmius fungal fibers have been frequently observed in neotropical bird nests. We tested to determine if superior tensile strength and temperature moderation contributes to why these fibers are preferred by some species over other available nesting materials. Marasmius fibers from nests of Yellow-olive Flycatchers (Tolmomyias sulphurescens) were compared to grass fibers from a Yellow-tailed Oriole (Icterus mesomelas) nest from the same area in Belize, Central America. We measured tensile strengths by a universal strength tester which stretched the fibers to their breaking point. We also used HOBO data loggers to compare the temperature differential between …

Effects Of Invasional Meltdown On Community Structure In Marine Ecosystems In The Damariscotta Estuary Of Maine, Kate Lazzeri

Student Research Poster Presentations 2021

Basibiont organisms form the foundation of marine ecosystems by providing additional space for new species to settle on as epibionts. Invasive epibionts may take advantage of this new basibiont presence, which leads to many harmful effects on native organisms such as competition for both resources and food. In some cases, invasive species facilitate recruitment of other invasive organisms, a phenomenon referred to as invasional meltdown, but it is not known if invasion of new basibionts increases invasive epibiont occurrence. The purpose of this study is to answer the following research questions: 1) does the invasion status of the basibiont alter …
