Spinnen en loopkevers ingezameld tijdens een korte bodemvalbemonstering te Doeveren (ZedelgemâOostkamp)
-
Spiders and carabid beetles were collected with pitfall traps during a short sampling campaign in the spring of 2017 (from 24/05 to 11/07) in the nature reserve Doeveren at ZedelgemâOostkamp. 49 species of spiders and 34 species of carabid beetles were found. We here discuss some particular species of both arthropod groups that are mentioned as threatened on the Red list for Flanders. We comment the management and heathland restoration measures of the last years and its impact on both faunas

A natural death assemblage of fishes from an early modern archeological context in Antwerp (Belgium)
-
Abstract An unusual concentration of tens of thousands small fish remains discovered during rescue excavations in the town of Antwerp, Belgium, is described. The material was found in a small depression with no associated archeological material but could be dated to the first half of the 16th century based on its stratigraphic position. About 3500 freshwater fish were found in articulating position and it is shown that they died naturally during a single depositional event after an exceptional flood. The species spectrum and the reconstructed fish lengths make it possible to document the season when the catastrophic mortality occurred. This assemblage differs from the few assemblages of natural mortality reported in the literature, which are all of the attritional type.

First record of the invasive longhorn crazy ant, Paratrechina longicornis (Latreille, 1802) (Hymenoptera: Formicidae) from Mt. Elgon, eastern Uganda
-
We report the first observation of the invasive longhorn crazy ant (Paratrechina longicornis) in the Mount Elgon region of eastern Uganda. About 43 000 ants were sampled in 256 locations throughout the Ugandan foot slopes of Mt. Elgon in the years 2014, 2015 and 2016. We found P. longicornis in five locations in and around the town of Budadiri, Sironko district. The visual species identification was confirmed by COI gene-based DNA barcoding. That this species was found in only a small area suggests that it has only been recently introduced. The impact that P. longicornis will have on the local agricultural system or the biodiversity within the Mount Elgon National Park remains unclear. The Mt. Elgon region is a unique key biodiversity area where baseline data can be collected now to quantify the effects of P. longicornis as it increases its distribution within the region.

Spectral Requirements for the Development of a New Hyperspectral Radiometer Integrated in Automated Networks - the Hypernets Sensor
-
Networking of automated instruments on unmanned platforms has proved to be the most effective way to provide validation data for earth observation optical missions. However, with most current networks, such as AERONET-OC [1] for water and RADCALNET for land [2], the validation data are multispectral and/or limited in viewing geometries, resulting in modelling associated uncertainties to cover all spectral bands of all sensors and to correspond to satellite viewing geometries. Therefore, the HYPERNETS Project is developing a new hyperspectral radiometer to be integrated in automated networks. The main goal of the project is to acquire hyperspectral measurements of water and land reflectance and validate every optical earth observation satellite remote-sensing sensor in the Visible-Near Infrared (VNIR) and Short-wave Infrared (SWIR) spectral range. The present study reports the spectral characteristics of current and future earth observation missions. These characteristics represent the main drivers for the design of the HYPERNETS sensor.
