Linking climate change to population cycles of hares and lynxThe 10-year population cycles of snowshoe hares and Canada lynx are the classic example of race between prey and predator in the ecological textbooks. By the use of historic fur harvest data, we find predation is necessary but not sufficient in causing the observed 10-yr cycles; while extrinsic climate factors are important in producing and modifying the sustained cycles. We find recent climate warming likely contributes to the recent decline of lynx population and disappearance of cycles by increasing rainfall but reducing snow in Canada.Oct 22, 2013 -

Further research published on New Phytologist found that elevated CO2 increased the abundance of the pea aphid by decreasing the ethylene signaling pathway in legume plantsElevated CO2 modifies the performance of herbivorous insects mainly by altering host plant nutritional quality and resistance. We previously reported that elevated CO2 enhanced biological nitrogen fixation (BNF) of Medicago truncatula , which resulted in an increased supply of amino acids to the pea aphids ( Global Change Biology 2013, 19: 3210-3223 ). Current study examined the N nutritional quality and aphid resistance of sickle, an ethylene-insensitive mutant of M. truncatula with super-nodulation, and its wild-type control A17 under elevated CO2 in open-top field chambers.Sep 29, 2013 -

A recent research concerning the effect of elevated CO2 on the interaction between legume plant and aphid were published on Global Change BiologyGlobal atmospheric CO2 concentration has been increasing at an accelerating rate, and is anticipated to reach at least 750 ppm by the year 2100 (IPCC, 2007). Rising atmospheric CO2 levels can dilute the nitrogen (N) resource in plant tissue, which is disadvantageous to many herbivorous insects. Aphid, a phloem sucker insect, appear to be an exception that warrants the further study. The current study used an N-fixing-deficient mutant (dnf1) of Medicago truncatula and its wild-type control to determine how elevated CO2 (750 ppm vs. 390 ppm) affects the nutritional interactions among host plant, pea aphid and its endosymbiont Buchnera.Aug 27, 2013 -
A Recent Progress on DNA Taxonomy - Heuristic optimization for global species clustering of DNA sequence data from multiple lociClustering molecular sequences based on the level of similarity can give information on the number and diversity of species, and is a very commonly used approach for assessing species level diversity in many taxonomic groups. The number of available multi-gene datasets is growing rapidly, although the literature is currently dominated with single gene analyses, with remarkably little discussion of integrated species clustering using multi-locus dataset.Aug 09, 2013 -
