Wageningen Marine Research (WMR) conducts a variety of monitoring programs in Dutch waters. These monitoring programs are conducted to gain knowledge of trends, abundance and diversity of fish species in the Dutch rivers and lakes. Many monitoring programs pay special attention to diadromous fish which …

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 …

Climate change is a major contributor to the range shifts of several organisms such as plant species. A range is the geographical area where a species can be found and it is possible for plant species to undergo a range shift while still being present in their original one. These plants are called range-expanders. …

Background: To date, women are most often diagnosed with bacterial vaginosis (BV) using microscopy based Nugent scoring or Amsel criteria. However, the accuracy is less than optimal. The aim of the present study was to confirm the identity of known BV-associated composition profiles and evaluate indicators …

There is a need for scientific research to support sustainable management of remaining forests located within palm oil plantations. As lianas have a significant impact on species diversity, structure and dynamics, they are an important element in tropical forests. This study examined liana carbon stock, …

While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few ‘hyperdominant’species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing morecarbon than any other ecosystem on …

Varanus species are a popular species in the exotic pet trade. Little is known about the distribution of these species and trade could have a negative impact on the status of wild populations. Indonesia and Papua New Guinea have a large diversity of Varanus species and are both known as major wildlife …

Onderzoeksverslag van studenten van van Hall Larenstein naar de vele baten die stadsbomen aan de mens kan leveren. Deze baten worden ecosysteemdiensten genoemd. Het onderzoek naar deze ecosysteemdiensten van stadsbomen, wil de de baten die de stadsbomen leveren inzichtelijk te maken en hier vervolgens …

In many countries the Eurasian otter (Lutra lutra) is extinct or numbers are declining; resulting in a classification as “near threatened” on the IUCN’s Red List. In one-third of the European countries, however, conservation efforts, enabled the return of the species or the improvement of weakened populations. …
