Habitat Use Of The Key Largo Woodrat (Neotoma Floridana Smalli), Lauren J. Barth
Habitat Use Of The Key Largo Woodrat (Neotoma Floridana Smalli), Lauren J. Barth
FIU Electronic Theses and Dissertations
Key Largo woodrats are an endangered subspecies with an extremely limited habitat. This study sought to understand woodrat habitat preferences in order to guide management. Woodrats build stick nests from natural and artificial materials, so nest distribution and nest occupancy were used as indicators of preference. Distribution was determined by nest surveys, and remote cameras were used to assess occupancy. Forest structure, human disturbance, nest, and animal presence metrics were also collected. More nests were found along abandoned roads than along forest transects and more artificial nests were occupied than natural nests. These findings indicate that woodrats prefer areas with …
Level Of Uv-B Radiation Influences The Effects Of Glyphosate-Based Herbicide On Fitness Of The Spotted Salamander, Nicholas A. Levis
Level Of Uv-B Radiation Influences The Effects Of Glyphosate-Based Herbicide On Fitness Of The Spotted Salamander, Nicholas A. Levis
Masters Theses & Specialist Projects
Numerous causes have been implicated in contributing to amphibian population declines since the 1980's, with habitat modification, ultraviolet radiation (UV-B) and environmental contaminants (such as glyphosate-based herbicide) being among the most common. This study identifies the effects of a generic glyphosate-based herbicide (GLY- 4 Plus) on mortality, immune function, body condition, and morphological plasticity of larvae of the spotted salamander (Ambystoma maculatum) under conditions that reflect open and closed canopy light regimes. Larval salamander responses to glyphosate-based herbicide varied depending on UV-B conditions. In general, it appears that an open canopy (i.e. greater UV-B exposure) may confer fitness benefits. In …
Biological Diversity And Seasonal Variation Of Mesozooplankton In The Southeastern Black Sea Coastal Ecosystem, İlknur Yildiz, Ali̇ Muzaffer Feyzi̇oğlu
Biological Diversity And Seasonal Variation Of Mesozooplankton In The Southeastern Black Sea Coastal Ecosystem, İlknur Yildiz, Ali̇ Muzaffer Feyzi̇oğlu
Turkish Journal of Zoology
In this study, the seasonal distribution of mesozooplankton was investigated between 1999 and 2006 at a station located in the southeastern Black Sea region. A total of 40 cruises were done within the southeastern continental shelf throughout this period in order to collect mesozooplankton samples. A total of 10 mesozooplankton species were identified. The average annual highest abundances of species were 67,770 ind./m^2 in 2000 (Penilia avirostris), 50,048 ind./m^2 in 2001 (Sagitta setosa), 42,143 ind./m^2 in 2006 (Oikopleura dioica), 27,987 ind./m^2 in 2005 (Acartia clausi), 25,792 ind./m^2 in 2001 (Oithona similis), 24,806 ind./m^2 in 2005 (Pseudocalanus elongatus), 12,094 ind./m^2 in …
Competition For Food Between The Markhor And Domestic Goat In Chitral, Pakistan, Nasra Ashraf, Maqsood Anwar, Iftikhar Hussain, Muhammad Ali Nawaz
Competition For Food Between The Markhor And Domestic Goat In Chitral, Pakistan, Nasra Ashraf, Maqsood Anwar, Iftikhar Hussain, Muhammad Ali Nawaz
Turkish Journal of Zoology
The markhor (Capra falconeri) is endangered globally as well as in Pakistan. The Chitral district in Pakistan supports one of the largest populations of this species. The rural communities of the district have large holdings of livestock, which make up a significant part of their livelihood system. The domestic goat is the dominant livestock species, and a potential competitor with the markhor due to habitat overlap. The present study was conducted to examine the extent of food competition between the markhor and domestic goat in Chitral. A total of 120 pellets of the 2 species were collected during the spring …

The Gill Morphology Of The Date Mussel Lithophaga Lithophaga (Bivalvia: Mytilidae), Deni̇z Akşi̇t, Beri̇a Falakali Mutaf
The Gill Morphology Of The Date Mussel Lithophaga Lithophaga (Bivalvia: Mytilidae), Deni̇z Akşi̇t, Beri̇a Falakali Mutaf
Turkish Journal of Zoology
The purpose of the present research was to study the descriptive anatomy of the gill of the mussel Lithophaga lithophaga. Mussels were collected from 2 sites in Antalya Bay, Turkey. Observations using stereomicroscopy and electron microscopy showed that the gills of L. lithophaga consist of homorhabdic filaments, a characteristic of the mytilids. The lamellae have cavities at their laterals in addition to their prominent ciliary structure on the frontal and lateral surfaces. The latero-frontal cilia extend in pairs, one attached to the other with a membrane and showing a composite structure. The ascending and descending lamellae are fused by fan-like …
Time-Activity Budgets Of Wintering Ferruginous Duck, Aythya Nyroca, At Gajoldoba Wetland, Jalpaiguri, India, Tanmay Datta
Time-Activity Budgets Of Wintering Ferruginous Duck, Aythya Nyroca, At Gajoldoba Wetland, Jalpaiguri, India, Tanmay Datta
Turkish Journal of Zoology
Results indicate resting as the main diurnal activity of Aythya nyroca, whereas feeding dominated during the night. Other than resting (56.3%), feeding (16.8%) and swimming (15.2%) were major activities of the diurnal time-activity budget, whereas preening (9.4%) and flying (2.3%) were less frequent and occupied a secondary rank. Feeding and swimming were prevalent during the morning and afternoon hours. During midday, most of the ducks indulged in resting. The small amount of time spent on diurnal feeding was compensated by voracious nocturnal feeding (64.6%), which peaked in the middle of the night. Human interference plays an important role in shaping …
Rotifers Of Southwest Iran: A Faunistic And Biogeographical Study, Raheleh Reihan Reshteh, Hassan Rahimian
Rotifers Of Southwest Iran: A Faunistic And Biogeographical Study, Raheleh Reihan Reshteh, Hassan Rahimian
Turkish Journal of Zoology
The fauna of freshwater rotifers from Khuzestan Province (Southwest Iran) was expected to be different from that of the rest of Iran because of its geographical position, past geological events, climatic conditions, and similarities to neighboring zoogeographical areas. To test this hypothesis, we first had to determine the rotifer fauna of Khuzestan and then compare it with the results of surveys from other parts of Iran as well as with those from neighboring regions. Samples were collected from 10 sites throughout the province from May 2009 to April 2010. During the study, 66 species were identified, mostly with distribution in …
Updated Checklist Of Sponges (Porifera) Along The Coasts Of Turkey, Bülent Topaloğlu, Alper Evcen
Updated Checklist Of Sponges (Porifera) Along The Coasts Of Turkey, Bülent Topaloğlu, Alper Evcen
Turkish Journal of Zoology
This study compiled the data from previous papers emphasizing sponge species on the Turkish coasts. In total, 131 species belonging to 46 families have been reported: 82 species from the Aegean Sea, 63 species from the Sea of Marmara, 51 species from the Levantine Sea, and 13 species from the Black Sea. Among these species, 3 species are new records for the marine fauna of Turkey: Rhizaxinella elongata, Axinyssa digitata, and Terpios gelatinosa. Raspalia viminalis is a new record for the Sea of Marmara. The morphological and distributional features of 3 species are presented. In addition, a checklist of the …

Pentastomids Of Wild Snakes In Australia, Crystal Kelehear, David M. Spratt, Denis O'Meally, Richard Shine
Harold W. Manter Laboratory: Library Materials
Pentastomids are endoparasites of the respiratory system of vertebrates, maturing primarily in carnivorous reptiles. Adult and larval pentastomids can cause severe pathology resulting in the death of their intermediate and definitive hosts. The study of pentastomids is a neglected field, impaired by risk of zoonoses, difficulties in species identification, and life cycle complexities. We surveyed wild snakes in the tropics of Australia to clarify which host species possess these parasites, and then sought to identify these pentastomids using a combination of morphological and molecular techniques. We detected pentastomid infections in 59% of the 81 snakes surveyed. The ubiquity of pentastomid …
