What herbs tell us about tropical forest age in Cameroon

This post was led by Jacob Willie 

 

Assessing forest ages can be an important measure for management, yet while temperate forests are generally well studied in this regard tropical systems lack often this knowledge. One would think that simply measuring tree height will already provide a proper estimate, yet the level of uncertainty is particularly high in fast-growing tropical tree species, hence prohibiting reliable estimates to tease apart younger from older successional stages.

Ten years after publication the Helgolandian Grey Seal population keeps pace with predictions

The North Sea is one of the most intensely used marine areas with over 80 million people living within 150 km from its shore and harboring one of the largest heavy industrial areas in the world. This intense use by humans comes with severe impacts on its manifold ecosystems for centuries but especially since industrial times.

Yet, over the last decades there has been a tremendous effort to protect the local biodiversity ranging from the establishment of a network of national parks to protect the Waddensea in the Netherlands, Germany and Denmark, which later reached UNESCO World Heritage status, to protection of Seabirds and large marine mammals of which the Grey Seal (Halichoerus grypus) is the local apex predator.

Zosteromics chronicles: lessons learned in gene expression

As part of planning the fieldwork for the upcoming Kenya expedition to sample DNA from highland-lowland lineages of white-eyes we thought that data on gene expression might be a nice additional source of information to be linked to the genomic work we seek. However, none of us has experience in transcriptomics or how we can preserve RNA under tropical field conditions.

Tell me the tree and I tell you what’s growing underneath

This post was done together with Stefanie DeGroote 

 

Forests are often species rich. Their big trees provide shelter for many other plant species that grow in their shade, forming the so-called understory. Forest ecosystem functioning benefits from species-rich understories. Thus, it is important to find out what influences diversity in this forest layer. Yet, the problem is that factors affecting understory diversity are hard to find out. It could be species composition and diversity of the trees or the size of the forest patch.

Where to Eat & Drink in Ghent during #EAB2017

Inspired by the local foraging and sightseeing guides of the annual ESA meetings posted on the Dynamic Ecology blog, we thought we should give you something similar for #EAB17. Since we are based in Ghent (and tried a lot), we present you a selection of TERECs most favorite locations for food, coffee, drinks, and dance so that you can make the most out of your conference stay here in Ghent and enjoy your networking at nice places! While trying some of these places you will already discover a lot of Ghent’s historic city center. For more info on the sightseeing aspects check visit.ghent.be.

Zosteromics chronicles: The yellow pages of the Avian Ecology & Evolution side of TEREC

 

With the launch of the TEREC blog, I thought it’s great to write about ongoing and upcoming stories on White-eyes. In case you don’t know or simply forgot, here’s the pitch: We want to study these little yellow birdies to learn about avian evolution and how adaptation is facilitated in rapidly changing environments. That said, we want to use the toolboxes in genomics and modeling to learn more about what makes the „great speciator“ (Ernst Mayr) so great.
