  • Conservation Biology and Global Change
    honeyeater (Melipotes carolae), a species that had never been described before (Figure 56.1). In 2005, a team of American, Indonesian, and Australian biologists experienced many mo- 56 ments like this as they spent a month cataloging the living riches hidden in a remote mountain range in Indonesia. In addition to the honeyeater, they discovered dozens of new frog, butterfly, and plant species, including five new palms. Conservation To date, scientists have described and formally named about 1.8 million species of organisms. Some biologists think Biology and that about 10 million more species currently exist; others es- timate the number to be as high as 100 million. Some of the Global Change greatest concentrations of species are found in the tropics. Unfortunately, tropical forests are being cleared at an alarm- ing rate to make room for and support a burgeoning human population. Rates of deforestation in Indonesia are among the highest in the world (Figure 56.2). What will become of the smoky honeyeater and other newly discovered species in Indonesia if such deforestation continues unchecked? Throughout the biosphere, human activities are altering trophic structures, energy flow, chemical cycling, and natural disturbance—ecosystem processes on which we and all other species depend (see Chapter 55). We have physically altered nearly half of Earth’s land surface, and we use over half of all accessible surface fresh water. In the oceans, stocks of most major fisheries are shrinking because of overharvesting. By some estimates, we may be pushing more species toward ex- tinction than the large asteroid that triggered the mass ex- tinctions at the close of the Cretaceous period 65.5 million years ago (see Figure 25.16).

Conservation genetics is a very good example of the practical use of scientific achievements in nature protection. Although its name seems to be self-defining, its specific area of interest, conceptual apparatus and methodological workshop are not widely known and recognizable. The purpose of this review is to clarify any ambiguities and inconsistencies in this respect. It explore what is conservation genetics, what research and practical issues does it deal with and how they can be solved.

  • Understanding Processes of Recovery of the Tibetan Antelope 1 C
    Overcoming extinction: understanding processes of recovery of the Tibetan antelope 1 C. LECLERC, C. BELLARD,G.M.LUQUE, AND F. COURCHAMP Ecologie, Syste´matique et Evolution, Centre national de la recherche scientifique UMR CNRS8079, Universite´ Paris-Sud, 91405 Orsay Cedex, France Citation: Leclerc, C., C. Bellard, G. M. Luque, and F. Courchamp. 2015. Overcoming extinction: understanding processes of recovery of the Tibetan antelope. Ecosphere 6(9):171. http://dx.doi.org/10.1890/ES15-00049.1 Abstract. Since the middle of the 20th century, the Tibetan antelope (Pantholops hodgsonii) has been poached for its wool to make luxury shawls, shahtoosh. This direct overexploitation caused a drastic decline in their population, with a loss of more than 90% compared to the baseline population a few decades ago. Assuming this is an anthropogenic Allee effect (AAE), human attraction for rarity can drive rare species to extinction, which could explain the increasing rates of antelope harvests, paralleling the escalating prices of shahtoosh as the species got rarer. Since 1999, international concern led to conservation actions and the population soon started increasing. This unique situation allowed the presence of an AAE in Tibetan antelope to be tested, as well as an assessment of the potential effects of conservation actions in the presence of this process. We developed a theoretical discrete-time population dynamics model and examined effects of variation in shahtoosh prices. Furthermore, we tested the effects of major conservation actions into our models assessing their relative contribution to population recovery. During the exploitation phase, we found some evidence supporting the presence of an AAE compared to non-AAE models when hunting ceased at antelope population sizes below 10% of the initial population size.

The four steps necessary for life to emerge on Earth. (This is according to accepted scientific evidence.) A. First: An abiotic (non-living) synthesis of Amino Acids and Nucleic Acids must occur. 1. The RNA molecule is believed to have evolved first. It is not as molecularly stable as DNA though. 2. The Nucleic Acids (DNA or RNA) are essential for storing, retrieving, or conveying by inheritance molecular information on constructing the components of living cells.. 3. The Amino Acids, the building blocks of proteins, are needed to construct the “work horse” molecules of a cell. a. The majority of a cell or organism, in biomass (dry weight of an organism), is mostly protein. B. Second: Monomers must be able to join together to form more complex polymers using energy that is obtained from the surrounding environment. 1. Seen in monosaccharides (simple sugars) making polysaccharides (For energy storage or cell walls of plants.) 2. Seen in the making of phospholipids for cell membranes. 3. Seen in the making of messenger RNA used in making proteins using Amino Acids. 4. Seen in making chromosomes out of strings of DNA molecules. (For information storage.) C. Third: The RNA/DNA molecules form and gain the ability to reproduce and stabilize by using chemical bonds and complimentary bonding.

Ladle 1,2 1 School of Geography and the Environment, Oxford University, South Parks Road, Oxford, UK; E-Mail: [email protected]; Tel.: +55-31-3899 1902; Fax: +55-31-3899-2735 2 Department of Agricultural and Environmental Engineering, Federal University of Viçosa, Viçosa, Brazil Received: 13 October 2009 / Accepted: 14 November 2009 / Published: 26 November 2009 Abstract: Extinction forecasting is one of the most important and challenging areas of conservation biology. Overestimates of extinction rates or the extinction risk of a particular species instigate accusations of hype and overblown conservation rhetoric. Conversely, underestimates may result in limited resources being allocated to other species/habitats perceived as being at greater risk. In this paper I review extinction models and identify the key sources of uncertainty for each. All reviewed methods which claim to estimate extinction probabilities have severe limitations, independent of if they are based on ecological theory or on rather subjective expert judgments. Keywords: extinction; uncertainty; forecasting; local extinction; viability 1. Introduction ―Prediction is very difficult, especially about the future‖ Nils Bohr, Nobel Prize winning physicist Preventing the extinction of species is probably the most emblematic objective of the global conservation movement. To fulfill this aim effectively requires that decision makers and environmental managers are provided with accurate information on: (1) the identities of specific species/populations with a high probability of going extinct without further interventions; (2) the predicted rates of extinction among a range of taxa in different geographic areas and biomes under various ecological scenarios.
