    Hurricane disturbance and tropical tree species diversity (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-10-29
    Description: The debate over the maintenance of high diversity of tree species in tropical forests centers on the role of tree-fall gaps as a primary source of disturbance. Using a 10-year data series accumulated since Hurricane Joan struck the Caribbean coast of Nicaragua in 1988, we examined the pattern of species accumulation over time and with increased sampling of individuals. Our analysis shows that the pattern after a hurricane differs from the pattern after a simple tree-fall disturbance, and we conclude that pioneers are limited in large disturbances and thus do not suppress other species the way they do in smaller disturbances.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vandermeer, J -- Granzow de la Cerda, I -- Boucher, D -- Perfecto, I -- Ruiz, J -- New York, N.Y. -- Science. 2000 Oct 27;290(5492):788-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University Herbarium, School of Natural Resources and Environment, University of Michigan, Ann Arbor, MI 48109, USA. jvander@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11052939" target="_blank"〉PubMed〈/a〉

    Clusters of ant colonies and robust criticality in a tropical agroecosystem (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-01-25
    Description: Although sometimes difficult to measure at large scales, spatial pattern is important in natural biological spaces as a determinant of key ecological properties such as species diversity, stability, resiliency and others. Here we demonstrate, at a large spatial scale, that a common species of tropical arboreal ant forms clusters of nests through a combination of local satellite colony formation and density-dependent control by natural enemies, mainly a parasitic fly. Cluster sizes fall off as a power law consistent with a so-called robust critical state. This endogenous cluster formation at a critical state is a unique example of an insect population forming a non-random pattern at a large spatial scale. Furthermore, because the species is a keystone of a larger network that contributes to the ecosystem function of pest control, this is an example of how spatial dynamics at a large scale can affect ecosystem service at a local level.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vandermeer, John -- Perfecto, Ivette -- Philpott, Stacy M -- England -- Nature. 2008 Jan 24;451(7177):457-9. doi: 10.1038/nature06477.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Kraus Natural Science Building, University of Michigan, Ann Arbor, Michigan 48109, USA. jvander@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18216853" target="_blank"〉PubMed〈/a〉

    Bats limit insects in a neotropical agroforestry system (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-04-05
    Description: Exclosure experiments have demonstrated the effects of bird predation on arthropods. In a Mexican coffee plantation, we excluded foliage-gleaning bird and bat predators from coffee plants. Effects of bats and birds were additive. In the dry season, birds reduced arthropods in coffee plants by 30%; birds and bats together reduced arthropods by 46%. In the wet season, bats reduced arthropods by 84%, whereas birds reduced them by only 58%. We conclude that previous "bird" exclosure experiments may have systematically underestimated the effects of bats.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams-Guillen, Kimberly -- Perfecto, Ivette -- Vandermeer, John -- New York, N.Y. -- Science. 2008 Apr 4;320(5872):70. doi: 10.1126/science.1152944.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Natural Resources and Environment, University of Michigan, Ann Arbor, MI 48109, USA. kimwg@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18388285" target="_blank"〉PubMed〈/a〉

    Enigmatic biodiversity correlations: ant diversity responds to diverse resources (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-04-10
    Description: A pattern noted in ecology is that diversity at one level begets diversity at other levels. In the case of consumers competing for similar resources, the diversity of those resources is thought to provide some degree of niche diversification in which a diverse set of consumer species can coexist. If, however, the diverse resources are not sufficiently distinct from one another, from the standpoint of the consumer species, such niche diversification will not exist. We experimentally show that a diverse array of twigs attracted 80% more species of twig-nesting ants than a monospecific collection of twigs. The specific tree species from which the twigs were derived did not explain the pattern. It appears that diversity per se at one level (twigs) creates conditions that promote diversity at another level (nesting ants).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Armbrecht, Inge -- Perfecto, Ivette -- Vandermeer, John -- New York, N.Y. -- Science. 2004 Apr 9;304(5668):284-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Natural Resources and Environment, University of Michigan, 430 East University, Ann Arbor, MI 48109, USA. inge@univalle.edu.co〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15073375" target="_blank"〉PubMed〈/a〉

    Species loss and aboveground carbon storage in a tropical forest (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-10-22
    Description: Tropical forest biodiversity is declining, but the resulting effects on key ecosystem services, such as carbon storage and sequestration, remain unknown. We assessed the influence of the loss of tropical tree species on carbon storage by simulating 18 possible extinction scenarios within a well-studied 50-hectare tropical forest plot in Panama, which contains 227 tree species. Among extinction scenarios, aboveground carbon stocks varied by more than 600%, and biological insurance varied by more than 400%. These results indicate that future carbon storage in tropical forests will be influenced strongly by future species composition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bunker, Daniel E -- Declerck, Fabrice -- Bradford, Jason C -- Colwell, Robert K -- Perfecto, Ivette -- Phillips, Oliver L -- Sankaran, Mahesh -- Naeem, Shahid -- New York, N.Y. -- Science. 2005 Nov 11;310(5750):1029-31.

    A keystone mutualism drives pattern in a power function (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-18
    Description: Data that can be described by a power function are ubiquitous in nature. Although there is consensus that such data frequently emerge generally from nonlinear complex systems, a variety of specific mechanisms may be responsible for creating the pattern in particular cases. Here, we report on the distribution of a scale insect (Coccus viridis) that is a common agricultural pest. Its distribution in an organic coffee farm in southern Mexico generally follows a power function, but there are subtle deviations from that function. We offer a biological explanation for both adherence to the power functions and associated deviations, along with supporting evidence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vandermeer, John -- Perfecto, Ivette -- New York, N.Y. -- Science. 2006 Feb 17;311(5763):1000-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109, USA. jvander@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16484494" target="_blank"〉PubMed〈/a〉

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Observations of the ponerine antEctatomma ruidum suggested that this is a cleptobiotic species which appears to use the pheromone trails of other ant species to locate individual workers carrying food. To test this hypothesis an arena was set up to quantify the position of eachE. ruidum that entered the arena with respect to its position on or off a well-established foraging trail ofPheidole radoszkowskii, a myrmicine. Encounters betweenE. ruidum andP. radoszkowskii are described. Quantitative data and behavioral observations support the cleptobiosis hypothesis. This study adds yet another dimension to the diverse array of foraging strategies of the Ponerinae.
