“…LST can be affected by westward Rossby waves in recent studies (Sheu et al, 2010;Zhang et al, 2010;Zheng et al, 2011). Rossby wave originate from the eastern/central North Pacific, which is the region where the wind stress curl has its largest amplitude and is the action center of the PDO-related wind anomalies (Mantua et al, 1997;Qiu 2003).…”

“…Herbicide susceptibility varies among these species (Gonzalez-Torralva et al, 2010;Zheng et al, 2011); however, due to the difficulty in their identification, reports of unsuccessful control might involve weed misidentification. Developing a deeper understanding of the genetic structure of these species may help scientists to develop more precise identification tools and effective strategies for control.…”

ABSTRACT. The distinction among Conyza canadensis, C. bonariensis, and C. sumatrensis is a challenge for weed science. In the current study, primers for microsatellite (SSR) loci were used to investigate the molecular divergence among the three species, the genetic structure of the populations at the molecular level and the level of genetic admixture among Conyza plants from southern Brazil. Twelve primers amplified well-defined DNA segments for all 88 samples of the three Conyza species. The estimated proportion of SSR polymorphic loci, number of alleles, and mean expected heterozygosity were higher in samples of C. bonariensis than in samples of C. sumatrensis or C. canadensis. Conyza canadensis was the species with the lowest molecular diversity. High genetic divergence was observed among the three species. The well-defined ancestral groups for each species led to the identification of samples of Conyza with ancestral genomes from the three species. Hybridization events between pairs of these species may have occurred in crop fields from southern Brazil. The high molecular diversity in resistant biotypes of C. sumatrensis indicated that these biotypes have a high potential to colonize new areas, which increases its potential as a weed.Keywords: horseweed, molecular divergence, SSR loci.Mistura genética em espécies de Conyza (Asteraceae) reveladas por marcadores microsatélites RESUMO. A identificação das espécies Conyza canadensis, C. bonariensis e C. sumatrensis tem sido desafiadora para a ciência das plantas daninhas. No presente estudo, primers para locos microssatélites (SSR) foram utilizados para investigar a divergência molecular entre as três espécies; mostrar como as populações estão geneticamente estruturadas em nível molecular e avaliar o nível de mistura genética entre as plantas de Conyza no Sul do Brazil. Doze primers amplificaram segmentos de DNA bem definidos em todas as 88 amostras das três espécies. A proporção estimada de locos SSR polimórficos, o número de alelos, e a heterozigosidade média esperada foram mais altos nas amostras de C. banariensis do que nas demais. C. canadensis foi a espécie com menor diversidade molecular. Divergência genética alta foi observada entre as três espécies. A formação de grupos ancestrais bem definidos para cada espécie levou à identificação de amostras de Conyza com genoma ancestral das três espécies. A ocorrência de hibridização entre as três espécies pode ter ocorrido nas lavouras do Sul do Brasil. A diversidade molecular alta em biótipos resistentes de C. sumatrensis indicou que estes biótipos têm um alto potencial para colonizar novas áreas, o que agrava seu potencial como planta daninha.Palavras-chave: buva, divergência molecular, locos SSR.

“…The second type is eddy generated locally by wind stress curl Wang et al 2008b); the orographic wind jet and enhanced wind stress curl in the lee of the Taiwan Island and Luzon Island chains could lead to stronger Ekman pumping and spin up eddies. The third type is eddy propagating from the western Pacific through the LS as Rossby waves (Sheu et al 2010;Zheng et al 2011). The eddies from the western Pacific could freely pass through the LS during fall and winter, when Kuroshio loops into the SCS with weakened potential vorticity (PV) gradient, but they are usually blocked during spring and summer when the Kuroshio leaps northward with strengthened PV gradient.…”

Satellite images of sea-surface temperature, surface chlorophyll a concentration, and sea-level anomaly, together with ocean reanalysis data of Asia and Indian-Pacific Ocean (AIPOcean1.0), are utilized to study the three-dimensional characteristics and evolution of an anticyclonic warm eddy adjacent to the southwest coast of Taiwan during October and November 2006. Originated from the Kuroshio intrusion in the Luzon Strait, but unlike previously found westward moving anticyclonic eddies (AE) in the northeastern South China Sea, this AE was so close to the Taiwan coast and stayed where it was formed for over 1 month until it dissipated. Energy analysis is utilized to study the evolution process of the AE, and it shows that the barotropic instability (BTI) and baroclinic instability introduced by the Kuroshio intrusion flow appear to be the main energy sources for the AE. Periodical enhancement/relaxation of local northeasterly monsoon and its associated negative wind stress curl modify the current patterns in this region, reinforce the intraseasonal variability of the Kuroshio intrusion flow, and act together with Kuroshio to form the AE. Eddies detected from AIPOcean1.0 data also show that AEs are most likely to be generated southwest of Taiwan during the transition period of summer monsoon to winter monsoon, and generally, the BTI of Kuroshio intrusion contributes more than the direct wind stress work to the increase of the eddy kinetic energy for the generation and growth of the AEs.
