El objetivo fue establecer la composición de especies de mariposas en dos localidades en la cuenca del río Tona. Se recolectaron mariposas en el proyecto Caracterización de la Entomofauna silvestre de la cuenca de río Tona, Santander. Se colectaron 262 ejemplares y 91 especies de las familias Hesperiidae, Pieridae, Lycaenidae, Riodinidae y Nymphalidae. La familia Nymphalidae tuvo la mayor abundancia (169) y riqueza de especies (56), y las especies más abundantes: Euptychoides laccine (15) y Pedaliodes phrasis (12). El análisis de calidad del inventario señaló una riqueza potencial de 168,61, proporción de especies observadas del 53,97% y esfuerzo de muestreo del 99,97%. Puente Rojo tuvo los mayores valores de diversidad: abundancia (168), riqueza observada (72), N0 (165,20), N1 (52,44) y N2 (36,66).

Colombia is a privileged country given the geographical position, the diversity of ecosystems and the great plant complexity, conditions that allow it to occupy the third place in diversity of diurnal butterflies. The objective of this work was to establish the composition of species of diurnal butterflies in four locations of the La Honda basin for which captures were made using entomological nets of 45 cm in diameter, in the project of Characterization of the wild Entomofauna of La Honda basin, located in the northeast of the Colombian Andes. Analysis of inventory quality and analysis of similarity between sampling sites were performed. A total of 226 specimens were collected belonging to 95 species of the family Hesperiidae, Papilionidae, Pieridae, Lycaenidae, Riodinidae and Nymphalidae, the last having greatest abundance (134) and richness of species (53). La Navarra was the site with greatest abundance (110) and richness of species (54). The analysis of inventory quality indicated a potential richness of 167.13 species, a proportion of observed species of 56.24% and a sampling effort of 99.82%. The comparison of inventories allowed establishing that butterfly communities are different for all sampling sites, although there is a slight similarity between La Navarra and La Purnia. Based on the analysis of the inventory quality, it is proposed to carry out new sampling for these and other locations, as well as at different times of the year.

For the purification of the abnormal prothrombin (Pt Metz), advantage has been taken of the existence in the family of three siblings who, being double heterozygotes for Pt Metz and a hypoprothrombinemia, have no normal Pt. Purification procedures included barium citrate adsorption and chromatography on DEAE Sephadex as for normal Pt. As opposed to some other variants (Pt Barcelona and Madrid), Pt Metz elutes as a single symetrical peak. By SDS polyacrylamide gel electrophoresis, this material is homogeneous and appears to have the same molecular weight as normal Pt. Comigration of normal and abnormal Pt in the absence of SDS, shows a double band suggesting an abnormal charge for the variant. Pt Metz exhibits an identity reaction with the control by double immunodiffusion. Upon activation by factor Xa, Pt Metz can generate amydolytic activity on Bz-Phe-Val-Arg-pNa (S2160), but only a very low clotting activity. Clear abnormalities are observed in the cleavage pattern of Pt Metz when monitored by SDS gel electrophoresis. The main feature are the accumulation of prethrombin l (Pl) and the appearance of abnormal intermediates migrating faster than Pl.

Abstract Epilobium belongs to the family Onagraceae, which consists of approximately 200 species distributed worldwide, and some species have been used as medicinal plants. Epilobium nankotaizanense is an endemic and endangered herb that grows in the high mountains in Taiwan at an elevation of more than 3300 m. Alpine herbs are severely threatened by climate change, which leads to a reduction in their habitats and population sizes. However, only a few studies have addressed genetic diversity and population genetics. In the present study, we developed a new set of microsatellite markers for E. nankotaizanense using high-throughput genome sequencing data. Twenty polymorphic microsatellite markers were developed and tested on 30 individuals collected from three natural populations. These loci were successfully amplified, and polymorphisms were observed in E. nankotaizanense. The number of alleles per locus (A) ranged from 2.000 to 3.000, and the observed (Ho) and expected (He) heterozygosities ranged from 0.000 to 0.929 and from 0.034 to 0.631, respectively. The developed polymorphic microsatellite markers will be useful in future conservation genetic studies of E. nankotaizanense as well as for developing an effective conservation strategy for this species and facilitating germplasm collections and sustainable utilization of other Epilobium species.

On The Road

We present the first lizard species list for the municipality of Juruti, state of Pará, Brazil. The list was drawn up as a result of data obtained from specimens deposited in the Herpetological Collection of the Museu Paraense Emílio Goeldi and from inventories conducted in 2008-2011. Sampling methods included pitfall traps with drift fences and time constrained searches. We considered the data collected by other researchers, incidental encounters and records of dead individuals on the road. We recorded 33 species, 26 genera and ten families. Norops tandai was the most abundant species. Compared with the other regions of Amazonia, the region of Juruti presented a large number of lizards. However, further studies with an increase in the sampling effort, could prove this area to be richer in lizards than that observed so far.

Hard Type

The Ni-hard alloys white-cast irons are generally used for high wear work. Among them, those with better impact resistance because of its low carbon content compared to the rest of the family, are studied in this paper. One experimental technique of characterizing the metallic materials is the microstructural study. Several metallographic attacks intended to reveal qualitatively each microconstituent that forms the alloy, as well as the segregation and solidification structure of casting, are studied in this article. The use of color metallography is fundamental in this case to distinguish clearly the microconstituents. The main objective of this paper is to propose a series of attacks that identify each one of the microconstituents present in the alloy that has not been reported up to date.
