Larval Life History And Abundance Of A Rare Salamander, Eurycea Junaluska (Plethodontidae), Travis Ryan
Travis J. Ryan
The larval life history of Eurycea junaluska was studied in three southwestern North Carolina populations. Populations were sampled quarterly over a 13 mo period and size-class analyses were used to evaluate the pattern of larval growth and metamorphosis. Young of the year appeared in the late spring and experienced rapid growth through the first summer. Growth slowed in the second year and metamorphosis usually occured in the summer at about 25.5 mo post-hatching, although some data suggest that either 1yr or 3yr larval periods may be possible. The overall larval growth rate of E. junaluska is estimated at 1.27 mm/mo, …

Spider silks exhibit remarkable properties, surpassing most natural and synthetic materials in both strength and toughness. Orb-web spider dragline silk is the focus of intense research by material scientists attempting to mimic these naturally produced fibres. However, biomechanical research on spider silks is often removed from the context of web ecology and spider foraging behaviour. Similarly, evolutionary and ecological research on spiders rarely considers the significance of silk properties. Here, we highlight the critical need to integrate biomechanical and ecological perspectives on spider silks to generate a better understanding of (i) how silk biomechanics and web architectures interacted to influence …

Connecting Through Consilience: Ecology, Society, Culture And Technology, Ruth Mirams, Alexander Hayes
Alexander Hayes Mr.
Amongst linguistic, cultural and geographic diversity, humanity is characterised by inquisitiveness, communication and a deep desire to connect with each other. Despite our advanced intelligence and technological capacity, we are creatures of nature - a species which occupies a habitat, depends on consumable resources and fragile in many ways. As a species, we currently face challenges including overpopulation, diminishing resources and habitat degradation. In essence, we are exhausting the resources we depend on. [1] Resource depletion, disruption, famine, growth and sustainability are all observable in other species and natural systems. Human societies and systems can be described through the same …

Uses Of Wild Plants In Ndumba, Eastern Highlands Province, Terence Hays

For Papua New Guineans,l as well as for those who wish to understand them better, traiditional knowledge of the local natural environment is a priceless resource. In the face of increasing commitments to a cash economy, however, many communities are rapidly losing their awareness and appreciation of the rich animal and plant worlds which are immediately available to them. As Powell has recently observed (1976), the recorded information regarding traditional plant knowledge and uses has tended to be widely-scattered in the literature and relatively difficult to access, especially for those who stand to benefit the most from it. A recent …
Does Niche Divergence Accompany Allopatric Divergence In Aphelocoma Jays As Predicted Under Ecological Speciation?: Insights From Tests With Niche Models, John Mccormack, Amanda Zellmer, L. Knowles
Does Niche Divergence Accompany Allopatric Divergence In Aphelocoma Jays As Predicted Under Ecological Speciation?: Insights From Tests With Niche Models, John Mccormack, Amanda Zellmer, L. Knowles

The role of ecology in the origin of species has been the subject of long-standing interest to evolutionary biologists. New sources of spatially explicit ecological data allow for large-scale tests of whether speciation is associated with niche divergence or whether closely related species tend to be similar ecologically (niche conservatism). Because of the confounding effects of spatial autocorrelation of environmental variables, we generate null expectations for niche divergence for both an ecological-niche modeling and a multivariate approach to address the question: do allopatrically distributed taxa occupy similar niches? In a classic system for the study of niche evolution—the Aphelocoma jays—we …
