Evaluación biológica poblacional de macha (Mesodesma donacium, Lamarck 1818) en la provincia de Islay, Arequipa. Febrero 2015

La evaluación se realizó entre el 20 y 26 de febrero 2015, el área de distribución de la macha comprendió la playa entre punta Corio y Sombrero Chico en la provincia de Islay; no se registró entre el Boquerón y La Ensenada. La mayor concentración se observó entre Las Cuevas y El Tablón (área de repoblamiento de Islay). La densidad relativa de las estaciones/transectos varió entre 0 y 20,39 ejem/m2. El área efectiva de distribución se calculó en 1´413.514 m2, se estimó abundancia en 7´722.393 ejemplares y biomasa total 147,58 t. Se analizó biométricamente 2.612 ejemplares, la talla varió entre 26 y 90 mm de longitud valvar (LV), con moda principal en 62 mm y secundaria en 76 mm, la longitud promedio fue 59,17 mm, el 89,43% estuvo debajo de la Talla Mínima de Captura (TCM= 70 mm). Los perfiles medios de playa fueron de pendiente suave que varió entre 1,00° y 1,72°; en el Sector sur (Punta de Bombón) se observó playas intermedias acercándose a los límites de playas disipativas (Ω entre 3,14 y 5,92), en el Sector norte (Dean Valdivia - Mejía) se observaron playas intermedias - disipativas (Ω entre 4,53 y 5,22). La temperatura superficial del mar varió entre 16,4 y 21,0 °C, promedio 18,2±0,02 °C. En el análisis del plancton, entre El Molle y Cardones y El Conto y Mejía, se observó larvas D y umbonadas con características similares a Mesodesma donacium.

Abad y señor de Rute. Don Juan de Córdoba y la repoblación de la banda morisca cordobesa

A real time Taqman RT-PCR for the detection of rabbit hemorrhagic disease virus 2 (RHDV2)

As key prey, the wild rabbit downsize constitutes a major drawback on the endangered Iberian lynx (Lynx pardinus) re-introduction in the Iberia. Several captive breeding units mostly located in Alentejo, endeavour the wild rabbit repopulation of depleted areas assigned for the lynx re-introduction. Here we report an RHDV2 outbreak that occurred in early 2016 in a wild rabbit captive breeding unit located in Barrancos municipality. The estimated mortality rate between March and April 2016 was approximately 8.67%. Anatomopathologic examination was carried out for 13 victimized rabbits. Molecular characterization was based on the complete vp60 capsid gene. The 13 rabbit carcasses investigated showed typical macroscopic RHD lesions testing positive to RHDV2- RNA. Comparison of the vp60 nucleotide sequences obtained from two specimens with others publically available disclosed similarities below 98.22% with RHDV2 strains originated in the Iberia and Azores and revealed that the two identical strains from Barrancos-2016 contain six unique single synonymous nucleotide polymorphisms. In the phylogenetic analysis performed, the Barrancos-2016 strains clustered apart from other known strains, meaning they may represent new evolutionary RHDV2 lineages. No clear epidemiological link could be traced for this outbreak where the mortalities were lower compared with previous years. Yet, network analysis suggested a possible connection between the missing intermediates from which the strains from Barrancos 2013, 2014 and 2016 have derived. It is therefore possible that RHDV2 has circulated endemically in the region since 2012, with periodic epizootic occurrences. Still, six years after its emergence in wild rabbits, RHDV2 continues to pose difficulties to the establishment of natural wild rabbit populations that are crucial for the self-sustainability of the local ecosystems.
