There is mounting evidence that efforts to mitigate the adverse effects of human activity on climate and biodiversity have so far been unsuccessful. Explanations for this failure point to a number of factors discussed in this article. While acknowledging cognitive dissonance as a significant contributing …

This study aimed to get more insight into the spatial distribution pattern of the macrobenthos at the Vlakte van de Raan in relation to environmental gradients (median grain size, salinity and bathymetry). 82 samples were collected in November 2016 with a Van Veen grab using the research vessel the ‘RV …

This paper describes the development of one solid phase extraction method for a wide group of pharmaceutical and industrial compounds in wastewater that is analyzed with two LC-MS/MS methods.

Bryophytes are small, haploid, non-vascular plants, which can be divided in three distinct phyla; the mosses (Musci), the liverworts (Hepaticae) and the hornworts (Anthocerotae) (Gradstein & Melick, 1996), (Touw, Kruijer, & Stech, 2016). They are valuable indicators of environmental chance, due to the …

Recent research has shown that many chloroplast markers commonly used for the identification of species in land plants are not useful in the moss genus Campylopus. The only known suitable marker in Campylopus is the nuclear ribosomal ITS1-5.8S-ITS2 region. However, evolutionary patterns of this region …

Naturalis is als biodiversiteitscentrum het instituut dat de rijkscollectie op het gebied van natuurhistorie beheert en hier onderzoek aan doet. Tevens ontsluit Naturalis de gegevens over de collectie in internationale netwerken: dit bevordert de wetenschap wereldwijd. Naturalis legt de nadruk op het …

There is consensus that plant species richness enhances plant productivity within natural grasslands, but the underlying drivers remain debated. Recently, differential accumulation of soil‐borne fungal pathogens across the plant diversity gradient has been proposed as a cause of this pattern. However, …

To ensure stability for ships, ballast water is often used to correct or adjust the list or trim of a ship. After loading the ballast water is often carried across the ocean and discharged in an area with another aquatic environment. As a result, invasive species can end up in the water and effect the …

Met het Verwonderpaspoort (VWP) heb ik mij bezig gehouden gedurende mijn afstudeerstage. Dit is een online platform voor leerlingen van 4 tot 12 jaar en is gekoppeld aan een leerlingenpas. Het platform bestaat nu twee jaar. Leerlingen volgen een activiteit bij één van de twaalf aangesloten Leidse …

The ‘Grand Challenges’ of our times, like climate change, resource depletion, global inequity, and the destruction of wildlife and biodiversity can only be addressed by innovating cities. Despite the options of tele-working, tele-trading and tele-amusing, that allow people to participate in ever …
