The Entrance As A Complex Ecotone In A Neotropical Cave, Xavier Prous, Rodrigo Lopes Ferreira, Claudia Maria Jacobi
The Entrance As A Complex Ecotone In A Neotropical Cave, Xavier Prous, Rodrigo Lopes Ferreira, Claudia Maria Jacobi
International Journal of Speleology
Cave entrances are transition zones with intermediate characteristics between epigean environments, which bear lower environmental stability, and hypogean environments, with lower food resources. Associated to these interfaces there is a specific community, capable of exploiting its unique and intermediate characteristics. This work investigated this community in a Brazilian limnestone cave, identifying its arthropod species composition and spatial distribution, and exploring its relationships with climatic and structural environment characteristics and trophic relations. An ecotone zone was identified, with 55 species found only in the ecotone, 49 species were shared with the epigean community, 37 species with the hypogean community, and 14 …

Biology Faculty Articles
Morphological variation in natural populations is a genomic test bed for studying the interface between molecular evolution and population genetics, but some of the most interesting questions involve non-model organisms that lack well annotated reference genomes. Many felid species exhibit polymorphism for melanism but the relative roles played by genetic drift, natural selection, and interspecies hybridization remain uncertain. We identify mutations of Agouti signaling protein (ASIP) or the Melanocortin 1 receptor (MC1R) as independent causes of melanism in three closely related South American species: the pampas cat (Leopardus colocolo), the kodkod (Leopardus guigna), and Geoffroy’s cat …

Sulfidic Spring In The Gypsum Karst System Of Monte Conca (Italy): Chemistry And Microbiological Evidences, Marianna Messina, Tiziana Grech, Fiorenzo Fiorenza, Alessandro Marlettta, Pietro Valenti, Salvatore Petralia
International Journal of Speleology
Monte Conca Cave is a karst system placed in Messinian evaporites, consisting of an active cave and a resurgence located on the massif of Monte Conca, Campofranco within the "Riserva Naturale Integrale di Monte Conca". A sulfidic spring is located in the terminal gallery of the cave. To characterize the physical and chemical parameters of the Monte Conca cave and of the sulfidic spring, air temperature, relative humidity, water pH, and concentrations of dissolved sulfides, nitrates and sulfates were monitored. The high sulfide consumption rate in the sulfidic spring, evaluated by a kinetic study, suggests that biotic consumption is dominant. …

Psychology Faculty Research
The objective of this research was to describe the organization, connectivity and microstructure of the corpus callosum of the spider monkey (Ateles geoffroyi). Non-invasive magnetic resonance imaging and diffusion-tensor imaging were obtained from three subjects using a 3T Philips scanner. We hypothesized that the arrangement of fibers in spider monkeys would be similar to that observed in other non-human primates. A repeated measure (n = 3) of fractional anisotropy values was obtained of each subject and for each callosal subdivision. Measurements of the diffusion properties of corpus callosum fibers exhibited a similar pattern to those reported in the …

Biomarkers Of Animal Health: Integrating Nutritional Ecology, Endocrine Ecophysiology, Ecoimmunology, And Geospatial Ecology, Robin Warne, Glenn Proudfoot, Erica Crespi
Biomarkers Of Animal Health: Integrating Nutritional Ecology, Endocrine Ecophysiology, Ecoimmunology, And Geospatial Ecology, Robin Warne, Glenn Proudfoot, Erica Crespi
Publications
Diverse biomarkers including stable isotope, hormonal, and ecoimmunological assays are powerful tools to assess animal condition. However, an integrative approach is necessary to provide the context essential to understanding how biomarkers reveal animal health in varied ecological conditions. A barrier to such integration is a general lack of awareness of how shared extraction methods from across fields can provide material from the same animal tissues for diverse biomarker assays. In addition, the use of shared methods for extracting differing tissue fractions can also provide biomarkers for how animal health varies across time. Specifically, no study has explicitly illustrated the depth …
Evolution And Ecology Of Two Iconic Australian Clades: The Meliphagidae (Birds) And The Hakeinae (Plants), Eliot Trimarchi Miller
Evolution And Ecology Of Two Iconic Australian Clades: The Meliphagidae (Birds) And The Hakeinae (Plants), Eliot Trimarchi Miller
Dissertations
The first part of this dissertation explores the evolution of two iconic groups of species through Australian climate space: the Meliphagidae, or honeyeaters, which are primarily nectar-feeding birds, and the Hakeinae, a section of the plant family Proteaceae. Both groups are inferred to have had their origins in Gondwanan rainforests that were widespread across Australia 45 million years ago and then diversified into more arid environments as the continent’s climate became more arid. Accordingly, dry environments are inhabited by closely related (phylogenetically clustered) sets of species, although, in contrast to the honeyeaters, Hakeinae communities are characterized by more localized diversification. …
Drift Algae In New Haven Harbor And Impacts On Benthic Communities, Roman Zajac, Andrea Mccarthy
Drift Algae In New Haven Harbor And Impacts On Benthic Communities, Roman Zajac, Andrea Mccarthy
Biology and Environmental Science Faculty Publications
In 2009 the University of New Haven initiated studies to develop a contemporary database and assessment of the benthic ecology of New Haven Harbor. Previous studies were last conducted in the 1970s and 1980s (e.g. McCusker, and Bosworth 1979, 1981, Rhoads and Germano 1982). Benthic populations and communities are excellent indicators of environmental conditions and are regularly used for environmental assessment in estuarine and coastal waters (e.g. Pearson and Rosenberg 1978, Rhoads et al. 1978, Zajac and Whitlatch 2001, Mangi 2003). Given the inherent ability of the benthos to integrate sediment and water quality, many environmental indicators and indices to …

The Role Of The Primary School Principal In Developing Student Leadership, Gregory Hine, Shane D. Lavery
The Role Of The Primary School Principal In Developing Student Leadership, Gregory Hine, Shane D. Lavery
Education Papers and Journal Articles
The development of student leadership potential is an important issue to investigate (Archard, 2009; Hine, 2013; McNae, 2011). Yet to date, little research efforts have focussed on student leadership development programs within primary schools (K - 6). This research examined three aspects of student leadership within eight Catholic primary schools in metropolitan Perth, Western Australia. These aspects included the principals’ understanding of the term ‘student leadership’, their perception of the most appropriate form of student leadership in Catholic schools, and how they envisaged their role within a student leadership program. Qualitative data were collected through the exercise of semi-structured interviews …

Significant climate risks are associated with a positive carbon–temperature feedback in northern latitude carbon-rich ecosystems,making an accurate analysis of human impacts on the net greenhouse gas balance of wetlands a priority. Here, we provide a coherent assessment of the climate footprint of a network of wetland sites based on simultaneous and quasi-continuous ecosystem observations of CO2 and CH4 fluxes. Experimental areas are located both in natural and in managed wetlands and cover a wide range of climatic regions, ecosystem types, and management practices. Based on direct observations we predict that sustained CH4 emissions in natural ecosystems are …

Biology Publications
Reticulitermes termites play key roles in dead wood decomposition and nutrient cycling in forests. They also damage man-made structures, resulting in considerable economic loss. In the eastern United States, five species (R. flavipes, R. virginicus, R. nelsonae, R. hageni and R. malletei) have overlapping ranges and are difficult to distinguish morphologically. Here we present a molecular tool for species identification. It is based on polymerase chain reaction (PCR) amplification of a section of the mitochondrial cytochrome oxidase subunit II gene, followed by a three-enzyme restriction fragment length polymorphism (RFLP) assay, with banding patterns resolved via agarose gel electrophoresis. The assay …

Spider Assemblages And Dynamics On A Seasonal Island In The Pripyat River, Belarus, Izabela Hajdamowicz, Lucyna Pilacka, Wlodzimierz Meissner
Turkish Journal of Zoology
Spider assemblages on a seasonal river meadow island were studied in spring 2006 and 2007. Samples were collected with a set of 20-30 pitfall traps once every 5 days. Altogether, 1179 spiders belonging to 30 species were collected. There were 5 constant dominant species: medium-sized wandering Pardosa prativaga, and small-sized air colonizers Oedothorax retusus, Erigone dentipalpis, Oedothorax fuscus, and Pachygnatha degeeri. The relatively low species diversity was higher in 2007 and grew throughout the season with the lowering of the water level. The total turnover of species involved the least abundant species (below 1% of the total), mainly Linyphiidae. Abundance …

Composition And Seasonal Variation Of Epigeic Arthropods In Field Margins Of Nw Portugal, Fátima Cristina Paulino Simão, Miguel Angel Carretero, Maria José Aires Do Amaral, Amadeu Mortágua Velho Da Maia Soares, Eduardo Mateos
Turkish Journal of Zoology
Field margins act as shelters for different arthropod taxa in agricultural fields. Several factors may promote seasonal changes in arthropod communities, especially in regions with marked seasonality, such as Mediterranean areas. Epigeic arthropods were sampled from the margins of fields located in northwestern Portugal during 2 contrasting seasons, spring and autumn. Organisms were identified to family or order level and seasonal variation in arthropod communities was evaluated. Abundance, group richness, and feeding guild parameters were affected by sampling season, with both abundance and richness being higher in spring. Of the groups captured in both seasons, most evidenced either higher abundance …
