Success Of Glover’S Reef Marine Reserve On Queen Conch (Strombus Gigas) Populations In Belize, Gianna Fanelli, Ciera Jarrett, Sara Joralemon 2021 University of Central Florida

Success Of Glover’S Reef Marine Reserve On Queen Conch (Strombus Gigas) Populations In Belize, Gianna Fanelli, Ciera Jarrett, Sara Joralemon

The Pegasus Review: UCF Undergraduate Research Journal

The queen conch (Strombus gigas) provides important economic, ecological, and societal benefits to local communities throughout the Caribbean. The species, however, has fallen victim to commercial exploitation and overfishing in many areas. In Belize, even with restricted harvesting seasons, size restrictions, and regulations set by the Convention on International Trade in Endangered Species (CITES), harvesting practices have significantly depleted populations. Marine reserves, including the Glover’s Reef Marine Reserve, were established to protect biodiversity and maintain populations of Belize’s natural coral reefs. Utilizing size, frequency, and evidence of harvesting (shell notches), the 2018 Tropical Marine Biology (BSC 3355) course ...


Holocene Records Of Nebraska Mammals, Hugh H. Genoways 2021 University of Nebraska - Lincoln

Holocene Records Of Nebraska Mammals, Hugh H. Genoways

Zea E-Books

A survey of the archeological and paleontological literature allowed a compilation of Holocene records of mammals in Nebraska. This survey identified Holocene records from 338 sites in 62 of the 93 Nebraska counties. These counties were located throughout state, but there was a concentration of sites in southwestern Nebraska where there were 27 fossil sites in Frontier County and 22 in Harlan County. Fossils sites were underrepresented in the Sand Hills region. Records of fossil mammals covered the entire Holocene period from 13,000 years ago until AD 1850. A minimum of 57 species (with eight additional species potentially present ...

First Description Of Deep Benthic Habitats And Communities Of Oceanic Islands And Seamounts Of The Nazca Desventuradas Marine Park, Chile, Jan M. Tapia-Guerra, Ariadna Mecho, Erin E. Easton, María De Los Ángeles Gallardo, Matthias Gorny, Javier Sellanes

Earth, Environmental, and Marine Sciences Faculty Publications and Presentations

Seamounts and oceanic islands of the Chilean Exclusive Economic Zone at the intersection of the Nazca and Salas y Gómez ridges lie within one of the least explored areas in the world. The sparse information available, mainly for seamounts outside Chilean jurisdiction and shallow-water fauna of the Desventuradas Islands, suggests that the area is a hotspot of endemism. This apparent uniqueness of the fauna motivated the creation of the large Nazca-Desventuradas Marine Park (NDMP, ~ 300,000 km2) around the small islands San Felix and San Ambrosio in 2015. We report for the first time a detailed description of benthic microhabitats ...

Dietary Overlap Between Native And Exotic Fishes Revealed Through Gut Content Analysis At Head Baloki, Punjab, Pakistan, Muhammad Imran, Abdul Majid Khan, Muhammad Tahir Waseem

Journal of Bioresource Management

An imminent threat to indigenous freshwater ichthyofauna is the introduction of alien fishes that can alter the behavior, population dynamics and native community structure. Thus, it is necessary to understand their feeding behaviour to avoid any unwanted incalculable loss. At sampling site, Head Baloki feeding habits both of native (L. calbasu, C. catla, L. rohita and C. mrigala) and alien (H. nobilis, H. molitrix, C. carpio, C. idella, C. auratus, O. aureus, O. niloticus and O. mozambicus) species were analyzed through frequency of occurrence and percentage by number from January 2017-December 2019. Results indicated that L. rohita remained herbivorous while ...


Qualitative Analysis Of A Resource Management Model And Its Application To The Past And Future Of Endangered Whale Populations, Glenn Ledder 2021 University of Nebraska - Lincoln

Qualitative Analysis Of A Resource Management Model And Its Application To The Past And Future Of Endangered Whale Populations, Glenn Ledder

CODEE Journal

Observed whale dynamics show drastic historical population declines, some of which have not been reversed in spite of restrictions on harvesting. This phenomenon is not explained by traditional predator prey models, but we can do better by using models that incorporate more sophisticated assumptions about consumer-resource interaction. To that end, we derive the Holling type 3 consumption rate model and use it in a one-variable differential equation obtained by treating the predator population in a predator-prey model as a parameter rather than a dynamic variable. The resulting model produces dynamics in which low and high consumption levels lead to single ...

Microhabitat Selection Of A Sicilian Subterranean Woodlouse And Its Implications For Cave Management, Giuseppe Nicolosi, Stefano Mammola, Salvatore Costanzo, Giorgio Sabella, Rosolino Cirrincione, Giovanni Signorello, Marco Isaia

International Journal of Speleology

Human activities in subterranean environments can affect different ecosystem components, including the resident fauna. Subterranean terrestrial invertebrates are particularly sensitive to environmental change, especially microclimatic variations. For instance, microclimate modifications caused by the visitors may directly affect local fauna in caves opened to the public. However, since numerous factors act synergistically in modulating the distribution and abundance of subterranean species, it remains challenging to differentiate the impact of human intervention from that of other factors. Therefore, evidence of the impact of tourism on cave invertebrate fauna remains scarce. Over a year and with approximately two visits a month, we investigated ...


Sex-Specific Variation Of Social Play In Wild Immature Tibetan Macaques, Macaca Thibetana, Tong Wang, Xi Wang, Paul A. Garber, Bing-Hua Sun, Lixing Sun, Dong-Po Xia, Jin-Hua Li 2021 Anhui University

Sex-Specific Variation Of Social Play In Wild Immature Tibetan Macaques, Macaca Thibetana, Tong Wang, Xi Wang, Paul A. Garber, Bing-Hua Sun, Lixing Sun, Dong-Po Xia, Jin-Hua Li

Biology Faculty Scholarship

Theories proposed to explain social play have centered on its function in establishing social relationships critical for adulthood, its function in developing motor skills needed to survive, and promoting cognitive development and social learning. In this study, we compared variations in social play among infant and juvenile male and female Macaca thibetana. Given that this species is characterized by female philopatry and male dispersal, we hypothesized that immature females use social play as a mechanism to develop bonds that persist through adulthood whereas immature males use play to develop social skills needed to successfully enter new groups. The results indicated ...

Interannual variability in grassland primary production is strongly driven by precipitation, nutrient availability and herbivory, but there is no general consensus on the mechanisms linking these variables. If grassland biomass is limited by the single most limiting resource at a given time, then we expect that nutrient addition will not affect biomass production at arid sites. We conducted a distributed experiment manipulating nutrients and herbivores at 44 grassland sites in 8 regions around the world, spanning a broad range in aridity. We estimated the effects of 5-11 years of nutrient addition and herbivore exclusion treatments on precipitation sensitivity of biomass ...

Entomology Publications

Honey bee colonies have a yearly cycle that is supported nutritionally by the seasonal progression of flowering plants. In the spring, colonies grow by rearing brood, but in the fall, brood rearing declines in preparation for overwintering. Depending on where colonies are located, the yearly cycle can differ especially in overwintering activities. In temperate climates of Europe and North America, colonies reduce or end brood rearing in the fall while in warmer climates bees can rear brood and forage throughout the year. To test the hypothesis that nutrients available in seasonal pollens and honey bee responses to them can differ ...


Free-Floating Invasive Fern Affects Freshwater Marsh Ecosystem Structure: Changes To Water Quality And Chemistry, Aquatic Vegetation, Fish, And Invertebrates, Charles Wahl 2021 Louisiana State University and Agricultural and Mechanical College

Free-Floating Invasive Fern Affects Freshwater Marsh Ecosystem Structure: Changes To Water Quality And Chemistry, Aquatic Vegetation, Fish, And Invertebrates, Charles Wahl

LSU Doctoral Dissertations

Aquatic invertebrates are important to the function freshwater marshes. They are vital to the transfer of energy from primary producers and organic matter to higher trophic levels. The structure of macroinvertebrate communities is directly associated with aquatic macrophyte diversity and abundance. Submerged macrophytes produce oxygen, are a food source, and provide physical habitat, which allows numerous aquatic organisms to exist. Introduction of the invasive free-floating aquatic fern giant salvinia, Salvinia molesta Mitchell, poses a risk to freshwater ecosystems through limited light penetration, decreased submerged macrophyte abundance, altered water quality and, changes in macroinvertebrate community structure and energy transfer. The objective ...


Male Competition Reverses Female Preference For Male Chemical Cues, Z. Vilella-Pacheco, L. D. Mitchem, Vincent A. Formica, E. D. Brodie III 2021 Swarthmore College

Male Competition Reverses Female Preference For Male Chemical Cues, Z. Vilella-Pacheco, L. D. Mitchem, Vincent A. Formica, E. D. Brodie Iii

Biology Faculty Works

Females must choose among potential mates with different phenotypes in a variety of social contexts. Many male traits are inherent and unchanging, but others are labile to social context. Competition, for example, can cause physiological changes that reflect recent wins and losses that fluctuate throughout time. We may expect females to respond differently to males depending on the outcome of their most recent fight. In Bolitotherus cornutus (forked fungus beetles), males compete for access to females, but copulation requires female cooperation. In this study, we use behavioral trials to determine whether females use chemical cues to differentiate between males and ...

Here, There, And Everywhere: The Problem With Microplastics In Water And What Women Scientists Are Doing To Solve It, Pamela Lazos 2021 University of Pennsylvania

Here, There, And Everywhere: The Problem With Microplastics In Water And What Women Scientists Are Doing To Solve It, Pamela Lazos

wH2O: The Journal of Gender and Water

Plastics — ubiquitous material we cannot seem to live without — are everywhere, but sadly we cannot live with plastics either, at least not peaceably, especially when you consider there will be more plastics in the ocean than fish by 2050. In the intervening years, the photodegradation of plastic resulting in microplastics pollution will be an even bigger problem, affecting every living creature in the ocean, and by extrapolation, mankind. The choices we make and the steps we take to combat the overabundance of plastics in our environment will dictate not just the next 30 years, but the fate of the world ...
