arcto makes up the prevailing toxa in terms of abundance in the pre-ETMEE assemblages, accounting for nearly 80% specimens and showing an increasing trend representing a bloom in the last pre-ETMEE levels.
On the contrary, the high diversification and radiation underwent by the Liospiriferina falloti group and very closely related toxa, which is conspicuous along the Pliensbachian-Toarcian transition virtually throughout the Iberian Range, is not evident in the I-LS, where this group is represented only by very scarce specimens of Liospiriferina nicklesi and L.
The diversity of brachiopods is also minimal in this interval in other sectors of the Iberian Range, although some toxa have been recorded in localities with more marly sedimentotion, such as Arino or Rambla del Salto (Garcia Joral and Goy, 2004).
En el caso gallego, A Toxa y Mondariz serian los balnearios prototipo del modelo elitista descrito, aunque en la region funcionaban otros muchos establecimientos (cuadro 2).
Algunos de los balnearios mas elitistas--entre ellos, los estudiados en este trabajo, A Toxa y Mondariz--sobrevivieron a las dificultades e incluso vivieron una especie de edad de plata durante la Dictadura de Primo de Rivera (1923- enero 1930).
El estudio de los casos de A Toxa y Mondariz nos permitira entender mejor el papel de los balnearios de lujo en la Restauracion espanola.
At the two-leaf stage, plant leaves (three plants per line) were infiltrated with purified Ptr ToxA, which was provided by S.
Simple linear regression analysis was performed to evaluate the association of sensitivity to Ptr ToxA with average reaction to P.
1] hybrids of two durum varieties (Entries 52 and 133), or the progenies of multiway crosses involving three to five durum genotypes (entries 40 and 138) showed different reactions to Ptr ToxA from their durum parents.
This population did not segregate for reaction to Ptr ToxA, but the extensive mapping data generated by Faris et al.
The youngest fully expanded leaf at the third leaf stage was infiltrated with purified Ptr ToxA provided by Dr.
Each bulk used for BSA was composed of individuals that were identical at the Tsn1 locus as identified by genotyping with Ptr ToxA infiltration analysis or by scoring of nearby RFLP markers.
