Short-term impact of 1997/1998 ENSO-induced disturbance on abundance and genetic variation in a tropical butterfly

Article Abstract:

A study aims to assess the change in Arhopala epimuta abundance and genetic makeup relative to the 1997/1998 El Nino Southern Oscillation-induced drought and fire, through combined demographic and genetic data inferred from the analysis of 5 microsatellite loci and mitochondrial deoxyribonucleic acid (mtDNA) control sequences. Results suggest that, for mobile species within recently fragmented habitat, habitat loss after disturbance may lead to local population extinction but may augment genetic diversity in remnant local populations because of increased gene flow.

High levels of genetic variation exist in Aspergillus niger populations infecting Welwitschia mirabilis hook

Article Abstract:

The results of the investigation of genetic variation among 89 isolates of Aspergillus niger from three geographically discrete populations of Welwitschia are reported. The aim of the investigation was to describe the genetic variation and diversity within each site and to determine whether patterns exist in the distribution of variation within and between sites.

Heritable components of feline hematology, clinical chemistry, and acid-base profiles

Article Abstract:

Evolution of a feline model to show the extent of genetic regulation in intraspecies variation in blood and serum expression of selected clinical measures is discussed. The results show that serum variability has a genetic basis and is segregating in the feline population.
