Theory predicts that environmental filtering determines species assemblages – and their reassembly dynamics in a changing habitat such as a recovering rainforest. This prediction can be tested by studying trajectories of functional trait and phylogenetic composition. Phil Hoenle and coauthors examined 13 morphological traits from a total of 284 ant …
Species differ in their shape, morphology and function. But individuals within a species can be highly variable, too. Such variation likely results from responses to different environmetal conditions. Diego Marín-Armijos, Adolfo Chamba-Carrillo and Karen Pedersen (SP6) studied variation between individuals within a species, an Ecuadorian dung beetle. They compared individuals …
Nos enorgullece presentar nuestro Boletín de REASSEMBLY (Reensamblaje), que resume nuestra experiencia, nuevos conocimientos y retos durante el primer año de nuestra Unidad de Investigación. Cada investigador doctoral y postdoctoral presentó aquí su punto de vista personal. Merece la pena leerlo si quiere echar un vistazo al corazón de nuestro …
We proudly present our Reassembly Newsletter, summarizing our experience, new insights and challenges during the first year of our Research Unit. Each PhD and postdoctoral researcher presented her or his personal views here – worth reading if you want to get a glimpse into the heart of our scientific endeavor. …
Do you know what “autohaemorrhaging” means? It is a deliberate release or ejection of blood (also termed reflex bleeding), reported from some lizards and snakes as well as some insects. It is often interpreted as defensive behavior against predator attacks. But whether reflex bleeding as a defense really works, and …
In our study area – the lowland Chocó rainforest – three monkey species act as important dispersers for tree seeds. Brown-headed spider monkeys climb skillfully through the tree canopies and live almost entirely on fruits. Mantled howlers shape the soundscape and eat both leaves and fruits. And Ecuadorian white-fronted capuchins …
Our PhD candidate Timo Metz (SP 1) presented one of our first results in the Reassembly Unit as a poster at an international meeting of the German Ecological Society (GFÖ) and two other organizations (SFE2, EEF) in Metz (November 24th, 2022). Timo has modelled the role of obligate vs non-obligate …
How quickly does the understory vegetation and litter layer recover following complete removal? This is the main question addressed in our perturbation-recovery experiment in 10 x 10 m subplots (P-REX). After nine months, the litter layer achieved a similar extent as an undisturbed forest patch, and many new tree seedlings …
We had a very fruitful workshop in the National Park Bayerischer Wald (link) in October 5-7th 2022. After a Kick-Off Meeting last year (Palmengarten Frankfurt) and a workshop on data management and networks in the new Chocó lab in March 2022, this has been our third actual reassembly of the …
You don’t often see velvet worms (Onychophora)! Arianna is currently sorting the arthropods from litter extractions of the Reassembly plots. We got excited to see the first velvet worm in this sample. Only few onychophorans are known from Ecuador so far. Fernando Villagomez immediately looked for some morphological details and …
