Selection Strategy Of Small Mammalian Preys By The Common Genet Genetta Genetta Between Natural And Anthropized Environments In Edough Forest Massif (Northeastern Algeria), Fatma Belbel, Mehdi Boukheroufa, Camelia Hesni Benotmane, Rym Sakraoui, Lina Rania Ikram Henada, Feriel Sakraoui

Journal of Bioresource Management

We analyzed fluctuations in of small mammals’ biodiversity through the winter diet of the common genet Genetta genetta (Linnaeus, 1958), to deduce the predator - adopted strategy according to the habitat conditions in which it occurs, particularly in anthropogenic environments. The field sampling was conducted during the 2020 winter season, in two contrasting environments of the Edough mountain range: natural site (Ain Boukal), and anthropized site (Bouzizi landfill). The analysis of 30 collected excrements in each of the two sites, allowed us to identify different food categories including small mammals. The result shows that the common genet is an excellent …


The Evolutionary Dynamics Of Infectious Diseases On An Unstable Planet: Insights From Modeling The Stockholm Paradigm, Angie T.C. Souza, Sabrina B.L. Araujo, Walter A. Boeger 2022 Universidade Federal do Paraná

The Evolutionary Dynamics Of Infectious Diseases On An Unstable Planet: Insights From Modeling The Stockholm Paradigm, Angie T.C. Souza, Sabrina B.L. Araujo, Walter A. Boeger

MANTER: Journal of Parasite Biodiversity

Emerging infectious diseases (EIDs) are, besides a question of food safety and public health, an ecological and evolutionary issue. The recognition of this condition combined with the accumulation of evidence that pathogens are not specialists in their original hosts evidences the need for understanding how the dynamics of interaction between pathogens and hosts occurs. The Stockholm Paradigm (SP) provides the theoretical fundaments to understand the dynamics of diseases and design proactive measures to avoid the emergence and reemergence of infectious diseases. In this review, we revisit the models that evaluate several aspects of the proposed dynamics of the SP, including …


Influence Of Environmental Factors On Surface Activity Of Paruroctonus Marksi (Scorpiones: Vaejovidae) In The Mojave Desert, Zia Nisani, Destiny Frederick, Alejandro Garcia-Plascencia, Daian Lopez, Robert Miller, Linhsan Trinh-Nguyen 2022 Marshall University

Influence Of Environmental Factors On Surface Activity Of Paruroctonus Marksi (Scorpiones: Vaejovidae) In The Mojave Desert, Zia Nisani, Destiny Frederick, Alejandro Garcia-Plascencia, Daian Lopez, Robert Miller, Linhsan Trinh-Nguyen

Euscorpius

Many environmental factors may influence the activity pattern of scorpions in arid ecosystems. We investigated the seasonal variations of Paruroctonus marksi scorpion activity in the Mojave Desert (California, USA). Black light surveys were carried out within two 100 ×100 m plots from August 2017 to September 2018. The majority (85%) of scorpions were found in open areas compared with being in vegetation. The presence of P. marksi was positively correlated with both water vapor pressure and soil temperature, while moon illumination had no significant effect on P. marksi foraging behavior. Scorpions might be using humidity as an indicator of prey …

Distribution And Soil Characteristics Associated With The Neches River Rose-Mallow (Hibiscus Dasycalyx), Morgan E. Langlinais 2022 Stephen F. Austin State University

Distribution And Soil Characteristics Associated With The Neches River Rose-Mallow (Hibiscus Dasycalyx), Morgan E. Langlinais

Electronic Theses and Dissertations

The Neches River rose-mallow, Hibiscus dasycalyx, is a rare herbaceous perennial endemic to East Texas. The threatened, obligate wetland species is currently at risk of being lost in the wild due to habitat loss, encroachment of nonnative and native plant species, and hybridization with two other Hibiscus congeners, Hibiscus laevis and Hibiscus moscheutos. Known locations of each of the three Hibiscus species were used to measure select soil characteristics and habitat variables associated with each of the rose-mallows. H. dasycalyx was concluded to be associated with more fertile soils and slightly more canopy coverage than H. laevis and …


Worldwide Distribution Of Cave-Dwelling Chelodesmidae (Diplopoda, Polydesmida), Rodrigo Salvador Bouzan, Jackson C. Means, Kaloyan Ivanov, Rodrigo L. Ferreira, Antonio Domingos Brescovit, Luiz Felipe Moretti Iniesta 2022 Universidade de São Paulo, Brazil

Worldwide Distribution Of Cave-Dwelling Chelodesmidae (Diplopoda, Polydesmida), Rodrigo Salvador Bouzan, Jackson C. Means, Kaloyan Ivanov, Rodrigo L. Ferreira, Antonio Domingos Brescovit, Luiz Felipe Moretti Iniesta

International Journal of Speleology

Chelodesmidae is one of the most species rich families within the Myriapoda. However, little is known regarding their association with caves. We provide a list of all Chelodesmidae taxa reported from caves, map their worldwide distribution, and discuss the troglomorphic features of the group. A total of 25 species and subspecies from 20 genera and 2 subfamilies have been recorded from 59 caves and cave systems in 11 countries. These numbers represent a surprisingly modest proportion (~3%) of the approximately 800 described species in the family. Records of cave-dwelling chelodesmids appear to be geographically biased with most taxa reported from …


Guano Among Bat Species From Two Regions Shows Influence Of Geography And Diet On Bacterial Community, Rahma Ahmed, Thomas McElroy, Shannon Whitney, Lydia Moore 2022 Kennesaw State Universtiy

Guano Among Bat Species From Two Regions Shows Influence Of Geography And Diet On Bacterial Community, Rahma Ahmed, Thomas Mcelroy, Shannon Whitney, Lydia Moore

Symposium of Student Scholars

Studies of bat guano have shown that the diversity and structure of associated microbial communities can be related to factors such as host phylogeny, life history and reproductive stage, geography, and diet. Many insectivorous bat species in the southeastern U.S. have generalist diets that may shift seasonally to take advantage of abundant prey species or maximize caloric intake. Seasonal shifts in prey availability or consumption should be reflected in a guano microbiome change. We also expected to detect distinct guano microbiomes within species. Within species, distinct microbial communities related to geography, and finally life history and reproductive stage. We compared …

Eat Your Invasives: A Practical And Historical Analysis Of Foraging For Invasive Foods, Grace Hartman

Honors Projects

This paper discusses both the historical and modern role of foraging and why people may decide to forage, as well as barriers new foragers may face and how they can be overcome. Furthermore, the paper discusses how foraging for invasive species can be used as a method of conservation and how simple foraging can be encouraged for this reason.


Caribbean Reef-Building Coral-Symbiodiniaceae Network: Identifying Symbioses Critical For System Stability In A Changing Climate, Shaman Patel 2022 Nova Southeastern University

Caribbean Reef-Building Coral-Symbiodiniaceae Network: Identifying Symbioses Critical For System Stability In A Changing Climate, Shaman Patel

All HCAS Student Capstones, Theses, and Dissertations

Increasing global ocean temperatures and frequency of marine heatwaves pose dire consequences for coral reefs. High temperatures often lead to disruptions in coral symbiosis resulting in coral bleaching, increasing the mortality of corals. However, corals can potentially avoid bleaching peril by associating with thermally tolerant symbionts. Here we provide a tool for understanding symbiosis network stability of Caribbean reef-building corals. We created a network of Caribbean hermatypic corals and their associated Symbiodiniaceae phylotypes. A bleaching model was applied to this network to test for resilience and robustness (R50) to thermal stress. It was also layered with trait data for coral …

With the theme, "Looking Ahead: People and Projects Shaping the Future," the Fall-Winter 2022-2023 leads with the first in what will be a series of articles about offshore wind development impacting Connecticut. That is followed by the inspiring story of how a dying forest was replanted for climate resilience. Next, a profile of longtime marine educator Tim Visel tells about his lasting impact on Connecticut schools and students. Lastly, the complex challenge of dealing with Contaminants of Emerging Concern is examined, with descriptions of how Sea Grant is involved and the particularly troublesome group of substances called PFAS.


Crustacean Assemblage Structure Over The Charlie-Gibbs Fracture Zone Of The Mid-Atlantic Ridge Collected During The 2009 Henry B. Bigelow Expedition, Kathryn Medina 2022 Nova Southeastern University

Crustacean Assemblage Structure Over The Charlie-Gibbs Fracture Zone Of The Mid-Atlantic Ridge Collected During The 2009 Henry B. Bigelow Expedition, Kathryn Medina

All HCAS Student Capstones, Theses, and Dissertations

The Charlie Gibbs Fracture Zone (CGFZ) consists of two nearly parallel fracture transform faults that intersect the Mid-Atlantic Ridge (MAR) axis. This area has high primary productivity and biomass levels due to the topography and water. A predominant hydrographic feature of the MAR is the Sub-Polar Front (SPF) which runs along the southern edge of the CGFZ and is known as a biogeographical boundary for multiple species. As part of The Census of Marine Life project Patterns and Processes of the Ecosystem of the northern Mid-Atlantic (MAR-ECO), this study analyzed the abundance and distribution patterns of the CGFZ crustacean community …


A Colonial-Nesting Seabird Shows No Heart-Rate Response To Drone-Based Population Surveys, Erica A. Geldart, Andrew F. Barnas, Christina A.D. Semeniuk, H. Grant Gilchrist, Christopher M. Harris, Oliver P. Love 2022 Great Lakes Institute for Environmental Research

A Colonial-Nesting Seabird Shows No Heart-Rate Response To Drone-Based Population Surveys, Erica A. Geldart, Andrew F. Barnas, Christina A.D. Semeniuk, H. Grant Gilchrist, Christopher M. Harris, Oliver P. Love

Great Lakes Institute for Environmental Research Publications

Aerial drones are increasingly being used as tools for ecological research and wildlife monitoring in hard-to-access study systems, such as in studies of colonial-nesting birds. Despite their many advantages over traditional survey methods, there remains concerns about possible disturbance effects that standard drone survey protocols may have on bird colonies. There is a particular gap in the study of their influence on physiological measures of stress. We measured heart rates of incubating female common eider ducks (Somateria mollissima) to determine whether our drone-based population survey affected them. To do so, we used heart-rate recorders placed in nests to quantify their …

First Report Of Intraguild Predation In Scorpions (Scorpiones: Buthidae) From Turkey, Şahin Toprak, Rıdvan Kurt, Ersen A. Yağmur 2022 Marshall University

First Report Of Intraguild Predation In Scorpions (Scorpiones: Buthidae) From Turkey, Şahin Toprak, Rıdvan Kurt, Ersen A. Yağmur

Euscorpius

Scorpions are predators of a wide range of invertebrates even including other scorpions. Larger species commonly prey on smaller species or juveniles. Here, we report three cases of intraguild predation of Mesobuthus mesopotamicus (Penther, 1912) and Compsobuthus matthiesseni (Birula, 1905) by Hottentotta saulcyi (Simon, 1880) (Scorpiones: Buthidae) in Şırnak Province, Turkey. These are the first cases reporting antagonistic interactions among scorpions in Turkey.


A Field Synopsis, Systematic Review, And Meta-Analyses Of Cophylogenetic Studies: What Is Affecting Congruence Between Phylogenies?, Valeria Trivellone, Bernd Panassiti 2022 University of Illinois at Urbana-Champaign

A Field Synopsis, Systematic Review, And Meta-Analyses Of Cophylogenetic Studies: What Is Affecting Congruence Between Phylogenies?, Valeria Trivellone, Bernd Panassiti

MANTER: Journal of Parasite Biodiversity

We conducted a field synopsis and systematic meta-analysis of studies that carried out cophylogenetic analyses using algorithms and available software. We evaluated the influence of three factors—namely, cophylogenetic method, association, and ecosystem type—on the outcome of the analyses, that is, the degree of congruence between phylogenies of interacting species.

The published papers were identified using 4 different databases and 13 keywords; we included all studies for which statistical approaches to compare phylogenies (cophylogenetic analyses) of interacting lineages were used. After the initial screening, 296 studies were selected to extract response variable (outcome of the cophylogenetic analyses, i.e., congruent, incongruent, or …
