Selection acts differently on males and females and drives their phenotypic dissimilarities. Most research has focused on males and how sexual selection shapes their ornaments and weaponry in the context of gaining access to female mates. This is not least due to the fact that humans, as most other vertebrates, show "conventional", "Darwinian" sex roles concentrating our perception on competitive males and caring mothers.

High-quality genomes are an important basis for biological and evolutionary research. However, generating assemblies of high completeness and contiguity requires ideally fresh, flash-frozen samples. The availability of such samples has become a major limitation for biodiversity genomics, in particular for rare or endangered species, or species inhabiting remote regions. On the other hand, museum collections house millions of samples in Germany and worldwide.

The BMBF-funded GBOL, the German Barcode of Life initiative, has been run successfully over the last eight years. It delivered an operative DNA barcode reference library for German animals, fungi and plants. However, a significant proportion of insect taxa has so far been excluded from GBOL and merely all biodiversity research, because no or only very insufficient expertise and information are available that allow to get a grip on them. They are called “Dark Taxa”.

SYNTHESYS+ subproject NA3.1 collects existing standards and practices in the biodiversity biobanking community and identifies gaps.

Pollination is crucial for maintaining angiosperm biodiversity and represents one of the most important ecosystem services. With the increasing threats of massive insect decline, studying pollination and associated networks has become more important than ever. In this study, we target the plant-pollinator networks of two important crops (caraway and apple) using a combination of traditional methods with DNA barcoding and metabarcoding.

Upgrade of an International subprogram (Indopacific Coral Reef Biodiversity and Conservation, IPCRBC) within the local Master program Aquatic Science at Sam Ratulangi University, Manado in order to prepare it for a Double Degree Master program with University of Bonn and Bremen and thus strengthening existing cooperation between teaching partners UNSRAT, ZFMK and ZMT with regard to future collaborations

The Indonesian coastline is characterized by an extremely high biodiversity. This project focusses on a specific bio-system, i.e. Opisthobranchia, their prey organisms, and the associated microorganisms. Based on our knowledge on systematics and ecology of these organisms, the final goal is to identify new drug leads for antibiotics development in a cooperation with colleagues from the Pharmaceutical Biology of the university of Bonn. Sea slugs, forced by the absence of a protective shell, developed highly specialized defense strategies to protect their sensitive epidermis against micro and small organisms, as well as larger predators like fish and crabs. Especially chemical substances fulfill this protective role.

The Enviro-Bio Working Group is a collaboration of biodiversity biobanks within ISBER and ESBB, the international and European biobanking societies.

Insects are one of the most species-rich groups of metazoan organisms. They play a pivotal role in most non-marine ecosystems and many insect species are of enormous economical and medical importance. Unraveling the evolution of insects is essential for understanding how life in terrestrial and limnic environments evolved. The 1KITE (1K Insect Transcriptome Evolution) project aims to study the transcriptomes (that is the entirety of expressed genes) of 1,000 insect species encompassing all recognized insect orders. For each species, so-called ESTs (Expressed Sequence Tags) will be produced…

AMARE is designed to optimize the signal-to-noise ratio in AFLP data sets (single or multiple primer combinations). It identifies potentially erroneous AFLP genotyping errors as the number of non-reproducible scored markers between replicated AFLP profiles of single individuals. As a measure of overall data quality, it simultaneously estimates general replicate error rates.

FASconCAT is a user-friendly software that concatenates rapidly different kinds of sequence data into one supermatrix file.
