Book Synopsis Ecology and Genetics of Habitat Fragmentation in Spiders of Hawaiian Kipukas by : Amy Gretchen Vandergast
Download or read book Ecology and Genetics of Habitat Fragmentation in Spiders of Hawaiian Kipukas written by Amy Gretchen Vandergast and published by . This book was released on 2002 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biological consequences of habitat fragmentation include changes in community structure, the genetic structure of populations, and species interactions. In the kipuka system, a network of forest fragments surrounded by historical lava flows on the Big Island of Hawaii, I investigated the long-term effects of fragmentation. I examined community structure and population genetic structure of a group of spiders in the genus Tetragnatha (Araneae: Tetragnathidae), and spider parasitism by a mermithid nematode (Nematoda: Mermithidae). Spider communities changed across the boundary between forest fragments and surrounding lava habitat, with a decrease in total species richness and diversity, coupled with a change in the dominant taxon from native Tetragnatha to native Cyclosa (Aranaidae). Severe habitat restrictions for some Tetragnatha species suggested that populations in kipukas may be genetically isolated from one another. I investigated the genetic structure of three Tetragnatha species with variation in population size and habitat specialization in kipukas (T. quasimodo, abundant generalist; T. anuenue, abundant forest specialist; T. brevignatha, rare forest specialist). Based on allozymes and mitochondrial COI, population subdivision among forest fragments was greater for forest specialists than for the generalist. For the specialists, T. brevignatha and T. anuenue, minimum estimates of gene flow among isolated fragments were 0.5 and 0 migrants per generation, respectively. However for the generalist, T. quasimodo, gene flow was high (& ge;20 migrants per generation), regardless of habitat fragmentation. Additionally, the evolutionary relationships among COI sequences were characterized for the three Tetragnatha species, using Tajima's D, a phylogenetic tree-building method, and nested clade analysis. Geographic associations among nested clades revealed evidence of a "volcano-hopping" colonization pattern in T. quasimodo and T. anuenue, and evidence of genetic subdivision in kipuka populations in T. anuenue. Both T. anuenue and T. brevignatha showed significantly negative estimates of Tajima's D, a signature of recent population expansion. These patterns suggest that geologic processes have affected the structure of populations across the Big Island and may be an integral component in the diversification of lineages in this group. Finally, the relationship between Tetragnatha spiders and parasitic mermithid nematodes was investigated. Based on a molecular analysis, Hawaiian spider mermithids appeared to be more closely related to a mainland Aranimeris species, a spider parasite, than to insect-infecting mermithids collected on Oahu and the mainland. In kipukas, parasitism was low (ranging from 0 to 4%) and the number of infected spiders differed significantly among forest fragments. The proportion of spiders parasitized was associated with fragment area, but not with spider density or species richness, suggesting that mermithids are sensitive to habitat fragmentation, but that changes in rates of parasitism do not affect spider community structure. In conclusion, overall results suggest that habitat fragmentation affects habitat specialists and generalists differently, as evident in community structure and population genetic structure. For Hawaiian Tetragnatha, the continual reshaping of the Big Island landscape due to volcanic activity is reflected in the genetic structure of populations, suggesting a link between island geology and micro-evolutionary processes within this group
Book Synopsis Tropical Forest Remnants by : William F. Laurance
Download or read book Tropical Forest Remnants written by William F. Laurance and published by University of Chicago Press. This book was released on 1997-06-21 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in an increasingly fragmented world, with islands of natural habitat cast adrift in a sea of cleared, burned, logged, polluted, and otherwise altered lands. Nowhere are fragmentation and its devastating effects more evident than in the tropical forests. By the year 2000, more than half of these forests will have been cut, causing increased soil erosion, watershed destabilization, climate degradation, and extinction of as many as 600,000 species. Tropical Forest Remnants provides the best information available to help us understand, manage, and conserve the remaining fragments. Covering geographic areas from Southeast Asia and Australia to Madagascar and the New World, this volume summarizes what is known about the ecology, management, restoration, socioeconomics, and conservation of fragmented forests. Thirty-three papers present results of recent research as well as updates from decades-long projects in progress. Two final chapters synthesize the state of research on tropical forest fragmentation and identify key priorities for future work.

Book Synopsis Tropical Biology and Conservation Management - Volume II by : Kleber Del Claro,
Download or read book Tropical Biology and Conservation Management - Volume II written by Kleber Del Claro, and published by EOLSS Publications. This book was released on 2009-05-11 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Tropical Biology and Conservation Management is a component of the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Tropical environments cover the most part of still preserved natural areas of the Earth. The greatest biodiversity, as in terms of animals and plants, as microorganisms, is placed in these hot and rainy ecosystems spread up and below the Equator line. Additionally, the most part of food products, with vegetal or animal origin, that sustain nowadays human beings is direct or undirected dependent of tropical productivity. Biodiversity should be looked at and evaluated not only in terms of numbers of species, but also in terms of the diversity of interactions among distinct organisms that it maintains. In this sense, the complexity of web structure in tropical systems is a promise of future to nature preservation on Earth. In the chemicals of tropical plant and animals, could be the cure to infinite number of diseases, new food sources, and who knows what more. Despite these facts tropical areas have been exploited in an irresponsible way for more than 500 years due the lack of an ecological conscience of men. Exactly in the same way we did with temperate areas and also tropical areas in the north of Equator line. Nowadays, is estimated that due human exploitation, nation conflicts and social problems, less than 8% of tropical nature inside continental areas is still now untouchable. The extension of damage in the tropical areas of oceans is unknown. Thus so, all knowledge we could accumulate about tropical systems will help us, as in the preservations of these important and threatened ecosystems as in a future recuperation, when it was possible. Only knowing the past and developing culture, mainly that directed to peace, to a better relationship among nations and responsible use and preservation of natural resources, human beings will have a long future on Earth. These volumes, Tropical Biology and Natural Resources was divided in sessions to provide the reader the better comprehension possible of issue and also to enable future complementation and improvements in the encyclopedia. Like we work with life, we intended to transform this encyclopedia also in a “life” volume, in what new information could be added in any time. As president of the encyclopedia and main editor I opened the theme with an article titled: “Tropical Biology and Natural resources: Historical Pathways and Perspectives”, providing the reader an initial view of the origins of human knowledge about the tropical life, and what we hope to the future. In the sequence we have more than 100 chapters distributed in tem sessions: Tropical Ecology (TE); Tropical Botany (TB); Tropical Zoology (TZ); Savannah Ecosystems (SE); Desert Ecosystems (DE); Tropical Agriculture (TA); Natural History of Tropical Plants (NH); Human Impact on Tropical Ecosystems (HI); Tropical Phytopathology and Entomology (TPE); Case Studies (CS). This 11-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It is the only publication of its kind carrying state-of-the-art knowledge in the fields of Tropical Biology and Conservation Management and is aimed, by virtue of the several applications, at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.

Download or read book Lessons from Amazonia written by Richard O. Bierregaard and published by Yale University Press. This book was released on 2001-12-11 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deforestation is occurring at an alarming rate in many parts of the world, causing destruction of natural habitat and fragmentation of what remains. Nowhere is this problem more pressing than in the Amazon rainforest, which is rapidly vanishing in the face of enormous pressure from humans to exploit it. This book presents the results of the longest-running and most comprehensive study of forest fragmentation ever undertaken, the Biological Dynamics of Forest Fragments Project (BDFFP) in central Amazonia, the only experimental study of tropical forest fragmentation in which baseline data are available before isolation from continuous forest took place.A joint project of Brazil’s National Institute for Research in Amazonia and the U.S. Smithsonian Institution, the BDFFP has investigated the many effects that habitat fragmentation has on plants, invertebrates, and vertebrates. The book provides an overview of the BDFFP, reports on its case studies, looks at forest ecology and tree genetics, and considers what issues are involved in establishing conservation and management guidelines.
