Tropical Rain Forest Abiotic Factor

Although tropical rain forests form the worlds most species-rich ecosystems, their origin and history remain unclear, except on the very short timescale of the last 40 000 years or so. This book provides the first comprehensive review of the history of tropical rain forests on a long term geological timescale, commencing with the origin of the angiosperms over 100 million years ago, which today overwhelmingly dominate these forests. Tropical rain forest evolution is discussed in a global context within an up to date plate tectonic, palaeogeographical and palaeoclimatic framework, primarily by reference to the record of fossil pollen and spores. A particularly important aspect of this book is that in addition to published literature, it relies heavily on unpublished palynological data generated for petroleum companies during the course of hydrocarbon exploration programmes. Without access to such data the book could not have been written. The main text of the book reviews the evolution of tropical rain forests on a continent by continent basis, culminating with a global synthesis of their history in relation to the changing positions of the worlds tectonic plates and changing climates. This section also establishes the age of the great tropical rain forest blocks and identifies the worlds oldest tropical rain forests. The final chapter compares 20th Century tropical rain forest destruction with prehistoric forest clearance in temperate regions, and looks for analogues of the present phase of destruction within the geological record before considering long term implications of total rain forest destruction. The book will be of interest to all concerned with tropical rain forests,especially biologists, botanists, ecologists, and students of evolution. It will be valuable for postgraduates and advanced undergraduates, as well as stratigraphers, palaeobotanists, palynologists, and petroleum geologists.

In the 1980s, numerous scientific surveys documented both declining bird populations, especially among Neotropical songbirds that winter in the tropics, and the loss of tropical rain forest habitat. Drawing the seemingly obvious conclusion, scientists and environmental activists linked songbird declines to loss of tropical habitats and alerted the world to an impending ecological catastrophe. Their warnings led to the establishment of the Neotropical Migratory Bird Conservation Program, also known as Partners in Flight, the self-proclaimed largest conservation effort in history. Looking back over more than a decade of efforts to save migrant birds, John Faaborg offers the first serious evaluation of the state of songbird populations today, the effectiveness of conservation programs such as Partners in Flight, and the reliability and completeness of scientific research on migrant birds. Taking neither an alarmist nor a complacent approach, he shows that many factors besides habitat loss affect bird populations and that Neotropical migrants as a group are not declining dramatically, though some species adapt to habitat alteration more successfully than others. Faaborg's state-of-the-art survey thus clarifies the kinds of information we will need and the conservation efforts we should undertake to ensure the long-term survival of Neotropical migrant birds.

Tropical and subtropical dry broadleaf forests - The tropical and subtropical dry broadleaf forest biome is located at tropical and subtropical latitudes. Though these forests occur in climates that are warm year-round, and may receive several hundred centimeters or rain per year, they deal with long dry seasons which last several months and vary with geographic location.

North Western Ghats montane rain forests - The North Western Ghats montane rain forests is a tropical moist broadleaf forest ecoregion of southwestern India. It has an area of 30,900 square kilometers (11,900 square miles), and lies above 1000 meters elevation in the Western Ghats range.

New Caledonia rain forests - The New Caledonia rain forests are a terrestrial ecoregion, located in New Caledonia in the South Pacific. It is a tropical moist broadleaf forest ecoregion, part of the Australasia ecozone.

Quinalt Rain Forest - The Quinalt Rain Forest is a rain forest in the US state of Washington in the valley formed by the Quinault River and Lake Quinalt. The valley is called the "Valley of the Rain Forest Giants" because of the number of record size tree species located there.
