    Near-complete extinction of native small mammal fauna 25 years after forest fragmentation (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-09-28
    Description: Tropical forests continue to be felled and fragmented around the world. A key question is how rapidly species disappear from forest fragments and how quickly humans must restore forest connectivity to minimize extinctions. We surveyed small mammals on forest islands in Chiew Larn Reservoir in Thailand 5 to 7 and 25 to 26 years after isolation and observed the near-total loss of native small mammals within 5 years from 〈10-hectare (ha) fragments and within 25 years from 10- to 56-ha fragments. Based on our results, we developed an island biogeographic model and estimated mean extinction half-life (50% of resident species disappearing) to be 13.9 years. These catastrophic extinctions were probably partly driven by an invasive rat species; such biotic invasions are becoming increasingly common in human-modified landscapes. Our results are thus particularly relevant to other fragmented forest landscapes and suggest that small fragments are potentially even more vulnerable to biodiversity loss than previously thought.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gibson, Luke -- Lynam, Antony J -- Bradshaw, Corey J A -- He, Fangliang -- Bickford, David P -- Woodruff, David S -- Bumrungsri, Sara -- Laurance, William F -- New York, N.Y. -- Science. 2013 Sep 27;341(6153):1508-10. doi: 10.1126/science.1240495.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, National University of Singapore, 14 Science Drive 4, Singapore 117543, Singapore. lggibson@nus.edu.sg〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24072921" target="_blank"〉PubMed〈/a〉

    Response to comments on "Can we name Earth's species before they go extinct?" (2013)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 2013-07-23
    Description: Mora et al. disputed that most species will be discovered before they go extinct, but not our main recommendations to accelerate species' discoveries. We show that our conclusions would be unaltered by discoveries of more microscopic species and reinforce our estimates of species description and extinction rates, that taxonomic effort has never been greater, and that there are 2 to 8 million species on Earth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Costello, Mark J -- May, Robert M -- Stork, Nigel E -- New York, N.Y. -- Science. 2013 Jul 19;341(6143):237. doi: 10.1126/science.1237381.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Leigh Marine Laboratory, Institute of Marine Science, University of Auckland, Post Office Box 349, Warkworth, New Zealand. m.costello@auckland.ac.nz〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23869006" target="_blank"〉PubMed〈/a〉

    Publication Date: 2013-01-19
    Description: A paper by Wearn et al. (Reports, 13 July 2012, p. 228) yields new insights on extinction debt. However, it leaves out the area dependence of the relaxation process. We show that this is not warranted on theoretical or observational grounds and that it may lead to erroneous conservation recommendations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Halley, John M -- Iwasa, Yoh -- Vokou, Despoina -- New York, N.Y. -- Science. 2013 Jan 18;339(6117):271. doi: 10.1126/science.1231438.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Applications and Technology, University of Ioannina, Ioannina, Greece. jhalley@cc.uoi.gr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23329033" target="_blank"〉PubMed〈/a〉

    Can we name Earth's species before they go extinct? (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-01-26
    Description: Some people despair that most species will go extinct before they are discovered. However, such worries result from overestimates of how many species may exist, beliefs that the expertise to describe species is decreasing, and alarmist estimates of extinction rates. We argue that the number of species on Earth today is 5 +/- 3 million, of which 1.5 million are named. New databases show that there are more taxonomists describing species than ever before, and their number is increasing faster than the rate of species description. Conservation efforts and species survival in secondary habitats are at least delaying extinctions. Extinction rates are, however, poorly quantified, ranging from 0.01 to 1% (at most 5%) per decade. We propose practical actions to improve taxonomic productivity and associated understanding and conservation of biodiversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Costello, Mark J -- May, Robert M -- Stork, Nigel E -- New York, N.Y. -- Science. 2013 Jan 25;339(6118):413-6. doi: 10.1126/science.1230318.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Leigh Marine Laboratory, University of Auckland, Post Office Box 349, Warkworth, New Zealand. m.costello@auckland.ac.nz〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23349283" target="_blank"〉PubMed〈/a〉

    Invasive plants have scale-dependent effects on diversity by altering species-area relationships (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-01-19
    Description: Although invasive plant species often reduce diversity, they rarely cause plant extinctions. We surveyed paired invaded and uninvaded plant communities from three biomes. We reconcile the discrepancy in diversity loss from invaders by showing that invaded communities have lower local richness but steeper species accumulation with area than that of uninvaded communities, leading to proportionately fewer species loss at broader spatial scales. We show that invaders drive scale-dependent biodiversity loss through strong neutral sampling effects on the number of individuals in a community. We also show that nonneutral species extirpations are due to a proportionately larger effect of invaders on common species, suggesting that rare species are buffered against extinction. Our study provides a synthetic perspective on the threat of invasions to biodiversity loss across spatial scales.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Powell, Kristin I -- Chase, Jonathan M -- Knight, Tiffany M -- New York, N.Y. -- Science. 2013 Jan 18;339(6117):316-8. doi: 10.1126/science.1226817.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Washington University in St. Louis, St. Louis, MO 63130, USA. kipowell@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23329045" target="_blank"〉PubMed〈/a〉

    Time scales of critical events around the Cretaceous-Paleogene boundary (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-02-09
    Description: Mass extinctions manifest in Earth's geologic record were turning points in biotic evolution. We present (40)Ar/(39)Ar data that establish synchrony between the Cretaceous-Paleogene boundary and associated mass extinctions with the Chicxulub bolide impact to within 32,000 years. Perturbation of the atmospheric carbon cycle at the boundary likely lasted less than 5000 years, exhibiting a recovery time scale two to three orders of magnitude shorter than that of the major ocean basins. Low-diversity mammalian fauna in the western Williston Basin persisted for as little as 20,000 years after the impact. The Chicxulub impact likely triggered a state shift of ecosystems already under near-critical stress.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Renne, Paul R -- Deino, Alan L -- Hilgen, Frederik J -- Kuiper, Klaudia F -- Mark, Darren F -- Mitchell, William S 3rd -- Morgan, Leah E -- Mundil, Roland -- Smit, Jan -- New York, N.Y. -- Science. 2013 Feb 8;339(6120):684-7. doi: 10.1126/science.1230492.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Berkeley Geochronology Center, 2455 Ridge Road, Berkeley, CA 94709, USA. prenne@bgc.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23393261" target="_blank"〉PubMed〈/a〉
