High dispersal
WebMixers of TMD series are vacuum mixers with 3 shafts used in the processing of high viscosity products. The particular configuration of the mixing shafts (two disperser shafts and one scraper shaft ) allows high dispersal capacity as well as very short process time. Web22 apr 2012 · Dispersal can stimulate speciation by facilitating geographical expansion across barriers or inhibit speciation by maintaining gene flow among populations. …

Web4 mar 2015 · The second theoretical model, developed by Cheptou & Massol , shows that as the probability of pollination decreases, evolution leads to a positive association between dispersal ability and full outcrossing (in particular dioecy). High dispersal is indeed favoured in spatio-temporal heterogeneous landscapes (Comins, Hamilton & May 1980). Web7 mar 2010 · High dispersal ability and low genetic differentiation in the widespread butterfly species Melanargia galathea. Jan Christian Habel 1,2, Marius Junker 1 & …
WebExtreme overall divergence and high extinction rates are typical of insular endemics. Thus, detecting and understanding nativeness is critical on islands. Resilience to extinction is explored through a mechanistic approach focusing on midwife toads (Anura: Alytidae: Alytinae), an ancient lineage that includes continental and insular species. All alytines … WebHigh grade dysplasia (HGD) refers to precancerous changes in the cells of the esophagus. Gastroesophageal reflux disease (GERD) can be complicated by Barrett’s esophagus …
WebHigh resolution grass pollen concentrations were compared between three microscale sites (<300 m apart) in a rural area in Worcestershire, UK. The grass pollen was modelled with local meteorology in a MANOVA (Multivariate ANOVA) approach to investigate factors relevant to pollen release and dispersion. Web27 gen 2015 · Understanding dispersal ability in pest species is critical for both theoretical aspects of evolutionary and population biology and from a practical standpoint, such as …
Web28 mar 2024 · However, species with large seeds are likely to suffer high seed mortality in areas with insufficient seed dispersal as aggregated undispersed seeds attract vertebrate and invertebrate seed predators as well as pathogens (Augspurger 1984; Chapman and Chapman 1995; Terborgh et al. 2011).
