Our main field of activity is Numeric-Morphology-Based-Alpha-Taxonomy (NUMOBAT) of the ant genera Bothriomyrmex, Camponotus, Cardiocondyla, Formica, Hypoponera, Lasius, Leptothorax, Myrmica, Plagiolepis, Tapinoma, Temnothorax and Tetramorium by means of high-resolution stereomicroscopy, imaging methods, geometric morphometrics and explorative and hypothesis-driven data analyses.

During the last decades, we developed an advanced methodology for NUMOBAT in ants that is basically applicable also in other groups of organisms. It consists of (1) measures for error reduction during microscopic investigation (Seifert 2002), (2) removal of allometric variance (Seifert 2008), (3) development and application of a new exploratory data analysis called Nest Centroid Clustering (NC clustering) and (4) a fine-tuning of generated clusters by means of canonical variance analysis.

We aim at taxonomic decision finding by integrative taxonomy – in ants mainly performed by combining data of external morphology, nuclear DNA, ethology and chorology.

Other focal points are investigation of phenomena of evolution such as hybridisation as a significant factor of speciation and adaptive radiation, Social Cleptogamy, individual and social polymorphism or sympatric speciation. Four separate research projects on interspecific hybridisation, which have been completed by publications, deal with hybridisation (1) of two more distantly related Formica species in south Finland, (2) of two closely related Formica species in Germany, (3) of three cryptic Formicaspecies in the Alps and (4) of two distantly related Messor species in Italy.

A long-term monitoring program of ant populations in Central Europe which has been launched in 1979 includes now 240 study plots of basically any habitat in which ants can reproduce. The program records the nest density of ants relative to 17 niche dimensions according to a standard protocol. The numerically recorded data allow a more precise investigation of species-specific patterns of adaptation or preferences and synecological issues such as species richness and biomass in dependency from environmental factors and interspecific displacement. These investigations pave the road for a truly predictive ecology and the data provide a valuable historic biodiversity archive. The data allowed for the first time to demonstrate that Gauze’s principle of competitive exclusion is acting on the level of multi-species communities and not only in reduced laboratory settings with pairs of unicellular organisms.

We developed a method for the standardized description of soil temperatures in terrestrial ecosystems. The method has been made available for the public since the year 2012 in the form of the freely downloadable software package CalibSoil. Recording of soil temperatures has been a special focus in the long-term monitoring project of ant populations in Central Europe since the year 1979. A long-term continuation of this program and evaluation of the data by CalibSoil will allow a more precise description, assessment and prediction of the consequences of global warming on the habitat level.

We are working on the final steps towards a global dragonfly assessment: assessing all Odonata species globally against the criteria of The IUCN Red List of Threatened Species. The assessments with information on ecology, distribution, threats and the threat categories are public available on www.iucnredlist.org. Information from this website is frequently used for conservation planning, environmental impact assessments and for scientific and public purposes.

Our focus is on Africa, where we are compiling information on ecology, biogeography and conservation for dragonflies for the continent (information is available on African Dragonflies & Damselflies Online), maintain a point locality database maintained and provide identification literature (The Dragonflies and Damselflies of Eastern Africa). Another focus is capacity building in Africa through workshops, training courses and the supervision of PhD candidates. We have been cooperating with various conservation agencies (IUCN, NABU, African Parks) and contributed surveys and recommendations for conservation actions.

CalibSoil allows you to determine

• the habitat-dependent and macroclimate-dependent  components of soil temperature of your study sites, independent of the weather fluctuations which usually occur within a season or between years,
• maximum calibrated soil temperature which is an indication of the mean seasonal heat stress, and
• mean calibrated soil temperature which is the deciding environmental variable influencing mean metabolic rate.

The procedure is simple enough to be introduced as a standard method in terrestrial ecology. In addition to the CalibSoilsoftware you need only:

(a) adequate thermometers recording maximum temperatures,
(b) data from one to three of the nearest meteorological stations – these data are the daily air temperature and sunshine duration on the investigation day and on the 14 days prior this date and the monthly mean air temperature and monthly sum of sunshine hours from May to August of the 10 years prior the year of investigation,
(c)  a sufficiently sunny day between 1 May and 31 August.

For further information, read the user manual of CalibSoil and the more detailed background information on the derviation of the method and the algorithms used. Both files are also included in the software package.

By 14 December 2023 the determined and systematically arranged parts of the collection contained more than 1,036,467 specimens of about 18,500 species (among them 17,500 Palaearctic). These are divided as follows. 

Type material is present from 255 species, including 134 holo-, lecto- oder neotypes. More detailed:  Formicidae (171, 113), Diptera (19, 11), Cicadina (51, 5), Hymenoptera without Formicidae (5, 1), Coleoptera (3, 1), Sternorrhyncha (5, 2) and Trichoptera (1, 0).

The oldest voucher specimens date to about 1860 and originate from the collections of the then Naturforschende Gesellschaft der Oberlausitz. The Pterygota collection remained rather marginal during the period from 1860 to about 1975. A severe decline in quality and quantity happened in the years between 1921 and 1946: due to financial shortcomings and the only unsalaried leadership of the whole museum, parts of the collections were sold or degenerated.

A significant improvement in state of preservation and systematic order as well as an increase in quantity began with the appointment of Rolf Franke as an Entomological Preparator (1972) and the installation of modern standard cabinets in separate storage rooms (1976). The appointment of a fixed post for a scientist in 1981 formed the fundament for an upswing of research that is focused from this time up to the present on systematic, ecology and evolution of largely Palaearctic ants.

The number of mounted, determined, systematically ordered and catalogued pterygote insects increased from about 130,000 in the year 1981 to about 410,000 in the year 2011 owing to donations, purchases and own collective activities. The ethanol collections of an estimated 500,000 specimens originate mainly from sampling during soil biology projects of the SMNG from the year 1960 up to the present. They are arranged in a very rough systematic order and are not scientifically developed.
