The ecological literature on eastern forest‐floor herbs and data collected in the southern Appalachians Tennessee North Carolina suggest five possible mechanisms for reducing or limiting alpha diversity of vernal logged stands, three which may also account slow recovery some herbaceous species: (1) logging reduces populations rarer herbs; (2) species are further reduced during successional stages following logging, either by inability to adapt changed microclimate competition with r...

The European wild boar Sus scrofa L., an exotic species, entered the Great Smoky Mountains National Park during 1940s. Because of their high reproductive potential and adverse impact on native flora fauna, hogs have become a major management problem within park. During summer 1973, quadrat sampling canopy understory Gray Beech Forest was conducted in both hog—free hog—occupied sectors Removal herbaceous other types hog rooting damage showed no direct relationship to importance any individual...

Torrey Bot.

Genetic variation was examined in Helonias bullata , a threatened perennial plant species that occurs isolated wetland habitats. Fifteen populations representing the species’ geographic range were sampled. diversity low for ( H es = 0.053) as well within ep 0.029). Of 33 allozyme loci examined, 11 (33%) polymorphic, while on average only 12.8% (4) of polymorphic populations. The number alleles per locus 2.36 and averaged 2.09 across For every genetic parameter calculated, H. lower than...

Most studies of microplastics in freshwater have investigated presence creeks and rivers below sewage effluents storm drains. This study examines microplastic distribution surface waters, including springs primary streams, located within small, urban Karst watersheds, with without sources wastewater treatment discharge. Study locales were Texas, United States, either Waco on the Brazos River or downstream from San Marcos River. Research teams collected 800 ml water four different small...

A survey of vernal, forest‐understory herbs was conducted on 52 routes, 10 sample sites each, along the Susquehanna River and its major minor tributaries in southeastern Pennsylvania northeastern Maryland. Mature forest stands, as compared to younger successional had a greater diversity cover native understory frequencies K ‐selected species such Trillium flexipes Dicentra canadensis . Vernal with high fidelity river corridor were likely be more mesic habitat preference, occupy limited range...

In Christianity, Wilderness, and Wildlife, Susan Bratton brings to life the tradition of Christian wilderness spirituality, from Old Testament accounts Noah Moses Celtic monasteries Franciscan order. She traces a long history divine encounters in biblical literature, including visions, providential protection, spiritual guidance, calls leadership - all which highlight importance nature thought. This book will command attention growing audience for works at intersection environmentalism spirituality.

Academics have critiqued the Abrahamic faiths, particularly Christianity, as inadequate to respond today’s environmental dilemmas due abstract theological qualities like concept of a unified or transcendent God. Christianity and Islam are earth’s most populous religions, however, they growing in global south. A literature review finds that both indigenous world religions develop strategies for sustainability. Examples include: Amazonian fisheries, Islamic gardens, monastic forest management,...
