Spatiotemporal Partitioning Of Mammalian Mesopredators In Response To Drought And Urbanization In California's Central Valley, Chad W. Moura
Cal Poly Humboldt theses and projects
Mammalian mesopredators commonly associated with human dominated landscapes often exhibit generalist diets, behavioral plasticity, and relatively high reproductive rates. Because of this wide range of adaptive traits, ecologists have been speculative of what conditions may drive species to change their activity and behavior to avoid or mitigate against resource competition, intraguild predation, and human disturbance. I investigated a community of common mesopredators within the Sacramento Metropolitan Area of California’s Central Valley to address whether species are spatially and/or temporally partitioning due to a defacto apex predator, coyotes (Canis latrans), and humans alongside large landscape altering disturbances: urbanization and drought. I …

Bat Boxes As Mitigation Tools: Factors Impacting Microclimate And Myotis Sodalis Roost Selection, Reed Crawford
Online Theses and Dissertations
Environmental degradation has led to declines in available natural roosting habitat for bats. To mitigate this loss, practitioners often deploy artificial roosts (e.g., bat boxes). There are no established species-specific practices for deployment strategy and roost design selection, but occupancy rates are known to vary across species and roost microclimates can be harmful to bats. Providing bats with thermally beneficial roosts during summer could enhance overwinter survival of WNS-affected species. To further our understanding of roost preference and microclimate, we deployed 40 rocket box roosts of 5 designs at field sites in Indiana and Kentucky. Roosts were deployed in clusters …

The Evolution Of Dragons, Laura J. Mayfield
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Dragons have been depicted in human art as early as 4500 BCE. For centuries, these fantasy creatures have inspired countless folk and fantasy tales, as well as appearing in the art of different cultures around the world. Now there are thousands of different depictions of these huge, flying, fire-breathing lizards, but are any of them possible? In this study, I reference peer-reviewed scientific articles, phylogenetic analysis, and paleoart studies to create biologically-sound dragons. Basing the dragon lineage on a real branch of webbed-winged scansoriopterygids—an extinct family of climbing and gliding maniraptoran dinosaurs—I explored the possible wing-structure, fire-breathing abilities, and effects …

Using Environmental Dna To Detect Estuarine Crocodiles, A Cryptic-Ambush Predator Of Humans, Alea Rose, Yusuke Fukuda, Hamish A. Campbell
Human–Wildlife Interactions
Negative human–wildlife interactions can be better managed by early detection of the wildlife species involved. However, many animals that pose a threat to humans are highly cryptic, and detecting their presence before the interaction occurs can be challenging. We describe a method whereby the presence of the estuarine crocodile (Crocodylus porosus), a cryptic and potentially dangerous predator of humans, was detected using traces of DNA shed into the water, known as environmental DNA (eDNA). The estuarine crocodile is present in waterways throughout southeast Asia and Oceania and has been responsible for >1,000 attacks upon humans in the past …

Peregrine Falcons Nest Successfully During Reconstruction Of Bridge Over Ohio River, Kate G. Slankard, Loren F. Taylor, Dan M. Stoelb, Charlie Gannon
Human–Wildlife Interactions
Peregrine falcons (Falco peregrinus) often nest on bridges over rivers and other waterways, resulting in the need for mitigation planning for bridge maintenance and reconstruction. However, mitigation guidelines for peregrine falcon nests during bridge reconstruction are lacking in the literature. In this paper, we describe the monitoring, spatial, and temporal buffers, nest box installation, and other methods that allowed peregrine falcons to nest successfully on the Milton-Madison (US-421) Bridge during demolition and reconstruction. Construction activities occurred over a 4-year period (2011–2014), and coordination with local road departments and contracted engineers was necessary to accommodate the falcon nest. Nonetheless, …

A coronavirus related to SARS-CoV-2 has been isolated from Malayan pangolins illegally imported into Guangdong Province. It is not the precursor of SARS-CoV-2, but a comparison of viral genome sequences provides further evidence that the virus currently infecting humans. Bats and pangolins have been suggested as the natural reservoirs of a large variety of viruses. Some researchers have given attention to other species as the origin of coronaviruses and none have referred to bats and pangolins as the two emerging coronaviruses origin, which have caused unexpected human disease outbreaks recently. Severe acute respiratory syndrome coronavirus (SARS-CoV) and the Middle East …

Gulf and Caribbean Research
Estimates of Colombian Caribbean coral percent cover in the Southern Caribbean are consistent with those throughout the Caribbean Sea, which has declined to about 10% of historical levels in the last few decades. Human activities like destructive fishing techniques in the marine parks have degraded the reefs over the last few decades. Colombia’s Marine Protected Areas (MPAs) have thousands of square kilometers to map and patrol and few resources to devote to scientific and restoration efforts. Efforts to implement sexual reproduction techniques for restoration are starting to successfully propagate and settle corals on ceramic plates for reef deployment in the …

Williams Honors College, Honors Research Projects
Here I characterized the central neuroanatomy of the Blackspotted Rockskipper, Entomacrodus striatus, native to French Polynesia. The neuroanatomy of E. striatus has not been studied prior to this paper. I used several histology and antibody staining techniques to accomplish this, including Crystal Violet, immunohistochemistry, immunofluorescence, and Bielschowsky’s Silver Nitrate staining. This paper describes the most successful techniques used, identifies major structures in the species’ neuroanatomy, and also explains why studying E. striatus is important in the future of vertebrate research.
Diurnal Time-Activity Budget And Foraging Techniques Of Red-Crested Pochards(Netta Rufina) Wintering At The Wetlands Of West Bengal, India, Arkajyoti Mukherjee, Sudin Pal, Subhra Kumar Mukhopadhyay
Turkish Journal of Zoology
The present study aimed at recording the time-activity budget and feeding techniques of red-crested pochards (RCPs) to test the hypotheses that feeding techniques were influenced by the sexes and contrasting physical conditions of the habitat. The timeactivity budget was quantified using the scanned sample approach. In this study, the mean sex ratio of the RCPs was recorded as 0.655. Dominant behavior was sleeping or resting (42.8% in February to 47.0% in January), followed by swimming (27.1% in February to 29.8% in December), feeding (10.9% in December to 16.6% in February), and preening (9.0% in January to 12.1% in February).

Ecotoxicological Investigation Of Cyanobacterial Crude Extracts Todaphnia Magna Under Subchronic Test Conditions, Tan Duc Nguyen, Xuan Quang Ngo, Thanh Luu Pham, Thanh Son Dao
Turkish Journal of Zoology
Cyanobacterial blooms often consist of mixtures of microcystin-producing and microcystin-free species, and both can cause unpredictable effects on aquatic organisms. In this work, the subchronic effects of the cyanobacterial crude extracts (CCEs) from microcystin-producing and microcystin-free cyanobacteria with different microcystin concentrations (1, 10, and 50 μgL$^{-1}$)on Daphnia magna were investigated. The life-history trait responses of D. magna to CCEs were determined based on survival, reproduction, and somatic growth. In addition, the physiological response, represented by the feeding rate of D. magna on green algae (Scenedesmus sp.), after exposure to both types of crude extracts was estimated. Our results showed that …

Problems With Basing Insect Ethics On Individuals’ Welfare, Susana Monsó, Antonio J. Osuna-Mascaró
Animal Sentience
In their target article, Mikhalevich & Powell (M&P) argue that we should extend moral protection to arthropods. In this commentary, we show that there are some unforeseen obstacles to applying the sort of individualistic welfare-based ethics that M&P have in mind to certain arthropods, namely, insects. These obstacles have to do with the fact that there are often many more individuals involved in our dealings with insects than our ethical theories anticipate, and also with the fact that, in some sense, some insects count as more than an individual and, in another sense, they sometimes count as less than an …

Prostaglandin E2 (PGE2) is a key paracrine mediator of ovulation. Few specific PGE2-regulated gene products have been identified, so we hypothesized that PGE2 may regulate the expression and/or activity of a network of proteins to promote ovulation. To test this concept, Ingenuity Pathway Analysis (IPA) was used to predict PGE2-regulated functionalities in the primate ovulatory follicle. Cynomolgus macaques underwent ovarian stimulation. Follicular granulosa cells were obtained before (0 h) or 36 h after an ovulatory dose of human chorionic gonadotropin (hCG), with ovulation anticipated 37-40 h after hCG. Granulosa cells were obtained from additional monkeys 36 h after treatment with …

The sensitivity of the medulla spinalis to ischemia and reperfusion has been shown in previous in vitro and in vivo studies. However, less is known about the effects of carvacrol administration following ischemia and reperfusion. It was hypothesized that carvacrol might have protective effects on motor neuron functionunder ischemia- and reperfusion-induced oxidative stress. A total of 24 adult Wistar rats were divided into three groups: group I (control group; n = 8), group II (spinal ischemia and reperfusion group; n = 8), and group III (spinal ischemia and reperfusion + carvacrol group; n = 8). Ischemia and reperfusion were performed …
