Review This is a unique book dealing with tick species imported to the US through human immigration, migratory birds, exotic animal trade etc. Although the name might suggest it would focus exclusively with ticks found in the US, there are also a few chapters explaining from which continents these invasive ticks were coming and which give valuable information about their ecology, related epidem...

Exotic annual grasses are a major challenge to successful restoration in temperate and Mediterranean climates. Experiments to restore abandoned agricultural fields from exotic grassland to coastal sage scrub habitat were conducted over two years in southern California, U.S.A. Grass control methods were tested in 5 m2 plots using soil and vegetation treatments seeded with a mix of natives. The t...

Controlled experiments show that arbuscular mycorrhizal fungi (AMF) can increase competitiveness of exotic plants, potentially increasing invasion success. We surveyed AMF abundance and community composition in Centaurea stoebe and Potentilla recta invasions in the western USA to assess whether patterns were consistent with mycorrhizal-mediated invasions. We asked whether (1) AMF abundance and ...

Nikodem J. Pop lawski A Relativistic Description of Hadronic Decays of the Exotic Meson π1 Exotic mesons are striking predictions of quantum chromodynamics that go beyond the quark model. They can provide great insight into understanding phenomena such as asymptotic freedom, confinement, and dynamical symmetry breaking. This work analyzes hadronic decays of exotic mesons, with a focus on the li...

A large number of experiments now appear to confirm the existence of the exotic, strangeness +1 θ baryon. The I = 3/2 exotic Ξ3/2 signal observed by NA49 remains to be confirmed (it is not seen by HERA-B, and its compatibility with earlier high statistics Ξ production experiments has also been questioned). Recently, H1 reported evidence for an anti-charmed exotic, though this state was not seen...

We investigate the spin 3/2 baryons in the 27-plet based on flavor SU(3) symmetry. For J = 3/2, we find all the candidates for non-exotic members. For J = 3/2−, we predict a new non-exotic member Λ(1780). Fitting the mass spectrum and calculating the widths of the members show an approximate symmetry of the 27-plet of SU(3). We find that the exotic members have relatively large widths and the Ξ...

A basic question of 4-manifold topology is whether the complex projective plane, CP, admits exotic smooth structures. Thus one is interested in knowing the smallest m for which CP#mCP 2 admits an exotic smooth structure. In the late 1980’s, Dieter Kotschick [K] proved that the Barlow surface, which was known to be homeomorphic to CP#8CP 2 , is not diffeomorphic to it. In following years the sub...

We used Malaise traps to examine the aerial arthropod community in riparian habitats dominated by native willow, exotic saltcedar, or a mixture of these two tree species in central Arizona, USA. Over the course of three sampling periods per year in 2003 and 2004, native habitats had significantly greater diversity (Shannon–Wiener) and supported different arthropod communities compared to exotic...

Theory predicts that stability should increase with diversity via several mechanisms. We tested predictions in a 5-year experiment that compared low-diversity exotic to high-diversity native plant mixtures under two irrigation treatments. The study included both wet and dry years. Variation in biomass across years (CV) was 50% lower in mixtures than monocultures of both native and exotic specie...

The studies on physical properties of wool of six breeds of sheep of Punjab, Jammu and Kashmir. Sixty wool samples, 10 from such of the six breeds were selected to study the physical properties of wool. The study revealed that Dorset (exotic) had maximum staple length followed by Rambuillet (exotic) had maximum staple length followed by Rambuillet (exotic), i.e. 6.03 cm and 5.74 cm respectively...
