Aphytophagy In The Miletinae (Lycaenidae): Phylogeny, Ecology, And Conservation, John Mathew

Biological Sciences Theses & Dissertations

Less than 1% of all Lepidoptera are aphytophagous; of these, a considerable proportion is found in the family Lycaenidae. The aphytophagous Lycaenidae are believed to have arisen from a mutualistic template involving ant attendance. With this association firmly in place, it is a relatively simple shift to exploitation, either of the ants themselves, through active carnivory on the brood/trophallactic feeding from adults, or by carnivory on ant-tended homopterans, with little to no interference by the ants. Among lycaenids, aphytophagy has arisen several times; most spectacularly in the subfamily Miletinae, where all of the approximately 150 species are presumed or known …

Butterflies Of The North Okanagan, British Columbia, Canada, David L. Threatful

The Taxonomic Report of the International Lepidoptera Survey

An annotated list of 106 species of butterflies known to occur in the north Okanagan area of British Columbia, Canada is presented. Information is provided on flight phenology, elevation and habitat for each species. Field work over the past 100 years shows that this is one of the premiere areas in Canada for butterfly species diversity. More than one third of all known Canadian butterflies have been found in this small area.

Conservation And Restoration Of Pine Forest Genetic Resources In México, C. Sáenz-Romero, Amy E. Snively, R. Lindig-Cisneros

Student Published Works

Deforestation rates in México are about 670,000 ha/year. This threatens the richness of forest genetic resources in México, causing the disappearance of locally adapted populations and rare and endangered pine species. México is one of the six megadiverse countries in the world, with half of the world’s Pinus species. Pinus is one of the most economically and ecologically important forest genera in México. We suggest that delineation of seed zones and the establishment of a network of Forest Genetic Resource Conservation Units (FGRCUs), linked with forest management and ecological restoration programs will protect this valuable resource. We estimate that FGRCUs …

G03-1512 Establishing Conservation Plantings Of Nut Trees And Shrubs By Direct Seeding Methods, Steven D. Rasmussen, Scott J. Josiah, John Wilson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to plant and raise nut trees and shrubs from seed. Seeding methods, planting design, site preparation and post-planting care are discussed.

Conservation tree and shrub plantings create wildlife habitat, improve water quality, produce marketable nuts, and enhance landscape diversity. Usually, nursery-grown seedlings are used to establish these plantings. However, a number of problems exist when using seedlings, including increased costs and reduced initial tree vigor and survival. Direct seeding of tree and shrub seeds avoids many of these problems, and is a proven, effective means to establish conservation plantings in Nebraska and elsewhere.

Community-Based Development Of Multiple-Use Marine Protected Areas: Promoting Stewardship And Sharing Responsibility For Conservation In The San Andres Archipelago, Colombia, Marion Howard, Ernesto Connolly, Elizabeth Taylor, June Marie Mow

Gulf and Caribbean Research

The San Andres Archipelago in the western Caribbean includes some of the largest and most productive coral reef ecosystems in the hemisphere. Declared the Seaflower Biosphere Reserve by UNESCO in 2000, this Colombian archipelago has 3 inhabited islands, 5 atolls, and an oceanic area of 300,000 km². CORALINA, the local representative of the National Environment System, is responsible for environmental planning, management, and education. While setting up the Seaflower Biosphere Reserve, this agency had hundreds of meetings with the islands’ communities, listening to their concerns. Issues, conflicts, and threats to marine and coastal areas were identified during these …

Cc03-431 Make Every Drop Count In Your Home

University of Nebraska-Lincoln Extension: Historical Materials

There are four ways to reduce water in your home ...

1. Maintain -- Fix leaks and dripping faucets. Leaks can account for 14 to 25 percent of all indoor water use.

2. Change -- Change the way water is used in the home.

3. Equipment -- Purchase water-reducing equipment and appliances.

4. Think -- Develop creative water conserving practices that are safe and sanitary.

Start wtih the largest water users. The toilet, shower/bath, and clothes washer account for two-thirds of the water used in an average household.

Taxonomy And Conservation Status Of Acantholimon Laxiflorum Boiss. Ex Bunge (Plumbaginaceae), Musa Doğan, Hayri̇ Duman, Gali̇p Akaydin

Turkish Journal of Botany

Acantholimon laxiflorum Boiss. ex Bunge (Plumbaginaceae), a local endemic species in Turkey, was subjected to taxonomic analysis in order to clarify its taxonomic status, because this species seems to have been wrongly treated and overlooked since it was first described by Boissier. The species is restricted to the east of Arsuz (C5 Hatay, Turkey) along dry riverbank, where it grows in rocky places on serpentine rocks. A full description and an illustration of the species are given, along with some additional information dealing with its ecology, phytogeography and conservation status.
