    305— Effects of Anthropogenic Noise on Frog Breeding Populations in Geneseo

    Get PDF
    With both amphibians and their wetland habitats in decline, it is critical to understand what ponds in the local landscape are used as breeding sites. Male frogs advertise for mates in the spring and summer by producing species-specific vocalizations at potential breeding sites. We are using acoustic recordings to examine three local sites for their use for breeding by frogs. Acoustic recordings collected during May 2020 will be analyzed to determine species abundance based on the temporal patterns of activity. By analyzing how the soundscapes and holistic metric of the habitats differ between sites can we understand the frogs\u27 habits. Using Raven Lite we can analyze call frequency to monitor breeding habits of Spring Peepers (Pseudacris crucifer), Northern Gray Treefrog (Dryophytes versicolor), Bullfrog (Lithobates catesbeianus), Wood Frog (Lithobates sylvaticus), and Green Frog (Hylarana erythraea). This research will expand our knowledge about how New York State species use roadside habitat and the behavioral adjustments they have to make to survive there

    The position of graptolites within Lower Palaeozoic planktic ecosystems.

    An integrated approach has been used to assess the palaeoecology of graptolites both as a discrete group and also as a part of the biota present within Ordovician and Silurian planktic realms. Study of the functional morphology of graptolites and comparisons with recent ecological analogues demonstrates that graptolites most probably filled a variety of niches as primary consumers, with modes of life related to the colony morphotype. Graptolite coloniality was extremely ordered, lacking any close morphological analogues in Recent faunas. To obtain maximum functional efficiency, graptolites would have needed varying degrees of coordinated automobility. A change in lifestyle related to ontogenetic changes was prevalent within many graptolite groups. Differing lifestyle was reflected by differing reproductive strategies, with synrhabdosomes most likely being a method for rapid asexual reproduction. Direct evidence in the form of graptolithophage 'coprolitic' bodies, as well as indirect evidence in the form of probable defensive adaptations, indicate that graptolites comprised a food item for a variety of predators. Graptolites were also hosts to a variety of parasitic organisms and provided an important nutrient source for scavenging organisms
