Five-minute bird counts were made on Rangitoto Island in 1998 and 1999, 8 and 9 years after the start, and 1 and 2 years after the completion of a 7-year programme that resulted in eradication of the introduced brushtail possum (Trichosurus vulpecula) and brushtailed rock wallaby (Petrogale penicillata). These were compared with counts made in 1990 (immediately before the start of the programme...

The quantitative analysis of low resolution spectra of A and B supergiants is used to determine a distance modulus of 24.99± 0.10 mag (995± 46 Kpc) Based on VLT observations for ESO Large Programme 171.D-0004.

Measurement techniques of nanoscale parameters have been vastly explored nowadays. In systems such as wood that possess anisotropic surfaces, these provide reliable data on the surface morphology and related parameters. The atomic force microscope (AFM) optical were used to investigate roughness Dinizia excelsa. Cuts made in different directions generating three distinct surfaces: radial, tange...

Results from a long-term observational project called the Araucaria Project are presented. Based on Wide Field optical monitoring of 8 nearby galaxies, covering a large range of metallicities, more than 500 Cepheids and a few hundred Blue Supergiant candidates were identified. From the analysis of Cepheid P-L relations of outstanding quality derived from our data we conclude that the slope of t...

Juniperus excelsa is the main tree species of forest stands in the upper elevations of the Kalamoun mountains in Syria. In this preliminary experiment seeds of juniper from four stands in different elevations (1900, 2100, 2200, 2250 m) were subjected to two pre-treatments with different duration period: warm stratification for three-months followed by 45 days warm stratification followed by 45 ...

In this study, we analysed spatial genetic structure (SGS) patterns and estimated dispersal distances in Milicia excelsa (Welw.) C.C. Berg (Moraceae), a threatened wind-pollinated dioecious African tree, with typically low density (approximately 10 adults/km(2)). Eight microsatellite markers were used to type 287 individuals in four Cameroonian populations characterized by different habitats an...

Neocunaxoides promatae sp. nov., Bonzia flechtmanni sp. nov. and Dactyloscirus multiscutus sp. nov. are described from soil and leaf litter in Atlantic rainforest and Atlantic Araucaria forest in natural environments in São Francisco de Paula municipality, Rio Grande do Sul State, Brazil. In addition, the species Pulaeus quadrisolenidius Castro & Den Heyer 2009 and Lupaeus lectus Castro & Den H...
