Increasing Capture Rates Of Grassland Birds Over Thirteen Years Indicates Successful Restoration, Katie Stumpf, Charles Muise
Increasing Capture Rates Of Grassland Birds Over Thirteen Years Indicates Successful Restoration, Katie Stumpf, Charles Muise
Georgia Journal of Science
Grassland bird populations are being lost at an alarming rate due to human modifications to grassland ecosystems. Grassland restoration has been shown to mitigate population declines for many species that use these habitats at some point in their annual cycles. We examined capture rates of adult, breeding, and hatch-year birds at a restored grassland site in the piedmont of central Georgia to determine whether colonization, breeding success, hatching success, and recruitment processes were impacting populations of grassland birds. We banded birds approximately twice per month from January 2009 through December 2021 at Panola Mountain State Park. Restoration efforts started in …

Summer To Autumn Population Of Wild Eumaeus Atala On The Ft. Lauderdale Campus Of Nova Southeastern University, Alexandra M. Lens
Mako: NSU Undergraduate Student Journal
Eumaeus atala is an endangered tropical butterfly native to the Caribbean and some parts of Florida, USA. Following population reductions primarily due to habitat loss, E. atala populations are now increasing due to conservation efforts of its cycad host plants, especially Zamia integrifolia (coontie). The purpose of this study was to observe, document, and measure the population of wild E. atala on the Ft. Lauderdale, Florida campus of Nova Southeastern University where landscaping use of host plants supports a natural population of E. atala. Forty-four host plants located in two different sites were observed for 14 weeks. One site …

Impacts Of Invasive Rats On Hawaiian Cave Resources, Francis G. Howarth, Fred D. Stone
International Journal of Speleology
Although there are no published studies and limited data documenting damage by rodents in Hawaiian caves, our incidental observations during more than 40 years of surveying caves indicate that introduced rodents, especially the roof rat, Rattus rattus, pose significant threats to vulnerable cave resources. Caves, with their nearly constant and predictable physical environment often house important natural and cultural features including biological, paleontological, geological, climatic, mineralogical, cultural, and archaeological resources. All four invasive rodents in Hawai‘i commonly nest in cave entrances and rock shelters, but only the roof rat (Rattus rattus) habitually enters caves and utilizes areas …
Checklist Of Bats In Some Areas Of Azad Jammu And Kashmir, Fakhra Nazir, Inayatullah Malik, Sabiha Shamim
Checklist Of Bats In Some Areas Of Azad Jammu And Kashmir, Fakhra Nazir, Inayatullah Malik, Sabiha Shamim
Journal of Bioresource Management
Bats form an essential part of the ecosystem by aiding pollination, keeping insect pests in check and overall maybe helpful as indicators of health status of the ecosystem. This study was conducted to formulate a checklist of bats from different regions in Azad Jammu and Kashmir. Five National parks from Azad Jammu and Kashmir were surveyed for the species of bats present (Dhirkot National Park, Pir Lasura National Park, Pir Chanasi National Park, Banjosa National Park and Tolipir National Park). From the study conducted, 10 species of bats belonging to 5 families were found cumulatively in the five national parks.
Insect (Arthropoda: Insecta) Composition In The Diet Of Ornate Box Turtles (Terrapene Ornata Ornata) In Two Western Illinois Sand Prairies, With A New State Record For Cyclocephala (Coleoptera: Scarabaeidae), Reese J. Worthington, E. R. Sievers, D. B. Ligon, P. K. Lago
Insect (Arthropoda: Insecta) Composition In The Diet Of Ornate Box Turtles (Terrapene Ornata Ornata) In Two Western Illinois Sand Prairies, With A New State Record For Cyclocephala (Coleoptera: Scarabaeidae), Reese J. Worthington, E. R. Sievers, D. B. Ligon, P. K. Lago
The Great Lakes Entomologist
A study of fecal samples collected over a two-year period from juvenile ornate box turtles (Terrapene ornata ornata Agassiz) revealed diets consisting of six orders of insects representing 19 families. Turtles were reared in captivity from eggs harvested from local, wild populations, and released at two remnant prairies. Identifiable insect fragments were found in 94% of samples in 2013 (n=33) and 96% in 2014 (n=25). Frequency of occurrence of insects in turtle feces is similar to results reported in previous studies of midwestern Terrapene species. A comparison of insect composition presented no significant difference between release sites. There is …

Can The Vaquita Be Saved From Extinction?, Gerardo Rodríguez-Quiroz, Wenceslao Valenzuela-Quiñonez, Héctor A. González-Ocampo, Alfredo Ortega-Rubio
Human–Wildlife Interactions
The vaquita (Phocoena sinus) is considered the world’s most endangered marine mammal. It is the smallest member of the porpoise family endemic to the upper part of the Gulf of California. The current population is estimated at less than 30 individuals. The primary reasons for the species decline includes limited habitat and incidental mortalities associated with illegal gillnet fishing activities. Since 2008, the Mexican government has taken environmental and economic actions to protect the vaquita’s focusing in reducing by-catch deaths to zero. In 2015, a federal Agreement decreed by the Secretaría de Agricultura, Ganadería, Desarrollo Rural, Pesca y …
Community Perceptions Of Grivet Monkey Crop Depredation In The Ethiopian Highlands: Implications For Primate Conservation, Aschalew Alelign, Meheretu Yonas
Community Perceptions Of Grivet Monkey Crop Depredation In The Ethiopian Highlands: Implications For Primate Conservation, Aschalew Alelign, Meheretu Yonas
Human–Wildlife Interactions
Human–primate conflicts in Africa have been increasing due to increased human population growth and the resulting competition for forest resources. The Ethiopian Highlands in northern Ethiopia, home to the grivet monkey (Chlorocebus aethiops), once consisted of large forested areas. This region has been severely denuded and now exhibits only small forest patches remaining at sites with special cultural significance in the immediate vicinity of churches. These forest patches, surrounded by agricultural crops, provide refugia habitat for the grivet monkey. We randomly surveyed 50 villagers living near the Batiero Church Forest, a 45-ha forest patch located in northern Ethiopia, to determine …
Genetic Analyses Determine Connectivity Among Cave And Surface Populations Of The Jamaican Endemic Freshwater Crab Sesarma Fossarum In The Cockpit Country, Manuel Stemmer, Christoph D. Schubart
Genetic Analyses Determine Connectivity Among Cave And Surface Populations Of The Jamaican Endemic Freshwater Crab Sesarma Fossarum In The Cockpit Country, Manuel Stemmer, Christoph D. Schubart
International Journal of Speleology
The Jamaican freshwater crab Sesarma fossarum (Decapoda: Brachyura: Sesarmidae) is endemic to western central Jamaica where it occurs in cave and surface streams of karst regions. In the present study, we examine the population genetic structure of the species, providing evidence for intraspecific differentiation and genetic substructure among twelve sampled populations. Interestingly, crabs from caves appear genetically undistinguishable from representatives of nearby surface waters, despite previously observed and described morphometric differentiation. In contrast, genetic isolation takes place among populations from rivers and caves belonging to different watersheds. In one case, even populations from different tributaries of the same river were …
Virginia’S Amphibians: Status, Threats And Conservation, Jennifer Sevin, John D. Kleopfer
Virginia’S Amphibians: Status, Threats And Conservation, Jennifer Sevin, John D. Kleopfer
Virginia Journal of Science
Virginia’s diverse environments support 84 amphibian species (anurans and caudates), making it the third highest state in terms of species richness. However, the Commonwealth matches the global trend in declining amphibian populations with over one-third of its amphibian species in conservation need. The Species of Greatest Conservation Need included in the most recent Virginia Wildlife Action Plan cut across amphibian families and ecoregions. It is challenging to ascertain the exact cause of most of the population declines. In one degree or another, all of the global threats to amphibians exist within Virginia’s borders. While an active research program on amphibians …
Breeding Birds Of Virginia, Bryan D. Watts
Breeding Birds Of Virginia, Bryan D. Watts
Virginia Journal of Science
Virginia supports a diverse community of breeding birds that has been the focus of investigation for more than 400 years. The avifauna reflects the latitudinal position of the state and the fact that the border extends from the Atlantic Ocean to the Appalachian Mountains. A total of 224 species have been recorded breeding in Virginia, 214 of which are extant. Twenty species have colonized the state since 1900 including 14 since 1950. Of all extant species, 102 (48%) are considered common at least somewhere in the state and 64 (30%) are rare to very rare. Diversity varies by physiographic region …
