Given the global continuous rise, artificial light at night is often considered a driving force behind moth population declines. Although negative effects on individuals have been shown, there no evidence for sizes to date. Therefore, we compared trends of Dutch macromoth fauna over period 1985-2015 between species that differ in phototaxis and adult circadian rhythm. We found show positive or are nocturnally active stronger than not attracted diurnal species. Our results indicate an...
Abstract The mating behaviour and the factors affecting male success in individually marked free-ranging red squirrels (Sciurus vulgaris) were studied over a 4 year period with aid of radio-telemetry. In coniferous area 12 mating-chases observed against 14 deciduous study area. A mean 3.19 adult males took part mating-chase, one which was leading that defended oestrous female. accounted for 24 29 matings, while five cases other able to mate successfully. had general highest dominance rank,...
The widely used Global Historical Climatology Network (GHCN) monthly temperature dataset is available in two formats—non-homogenized and homogenized. Since 2011, this homogenized has been updated almost daily by applying the “Pairwise Homogenization Algorithm” (PHA) to non-homogenized datasets. Previous studies found that PHA can perform well at correcting synthetic time series when certain artificial biases are introduced. However, its performance with real world data less studied....
Currently, numerous strategies and new initiatives for improving quality of schooling at the primary secondary levels are being considered implemented, with strong support from multilateral agencies, including World Bank IDB. These include increasing availability teaching materials, in-service training teachers, improvement methods, supply subsidized breakfast lunches school, etc. There is little dispute these important necessary interventions. However, design, monitoring evaluation...
Abstract In 2016, the Royal Dutch Meteorological Office (KNMI) homogenized daily temperature records for Netherlands from 1901 to 1950 allow a realistic comparison of temperatures present. The homogenizations main station De Bilt were carried out using Percentile Matching Method (PMM) with one reference and 56-month period. this study, it is shown that corrections in number tropical days (maximum ≥ 30 °C) depend strongly on choice length A total 116 different variants homogenization out, all...
Butterflies of the genus Maniola are known for their large morphological variation, at inter- as well intraspecific level. Given overlap in wing-patterns, habitat selection, and geographic distribution various species, genitalia morphology is sometimes only possibility to tell specimen apart. In this paper we describe diagnostic characters distinguish different species by means genitalia. Included also first detailed description illustration apparatus Sardinian endemic nurag . Further, two...
