About us

Accurate spatial analyses are undoubtedly resulting from processing of large amount of data. Ongoing invasions and diseases are making traditional mapping methods rapidly outdated, but with our reliable and scientifically-proven source of distribution data, you can reach the most accurate results possible.

Our geoportal features built-in visualization modules of crayfish species and records of the crayfish plague pathogen (Aphanomyces astaci) based on scientifically validated data. Our IT magicians works to implement multiple advanced functions in the benefit of science.

The platform is open for anyone but there are two layers of users. Non-registered users can view our maps in a simplified format, with a hexagonal overlay covering the exact locations. While this provides a general overview of crayfish distributions, registered members of the International Association of Astacology can access more advanced features. This includes downloading maps and generate datasets of geospatial variables specifically customised to freshwater habitats within the framework of global hydrographical network.

Our platform has multiple applications, including providing a comprehensive understanding of the invasion phenomenon and the geographic relationships between species ranges. It can also help investigators improve their own studies by providing quick and easy access to raw data on crayfish locations. The downloadable geospatial variables we offer can be used in various species distribution modelling analyses.

The platform is still in its early stages of development, but it already provides a variety of useful tools for those interested in crayfish knowledge.

The most basic function, accessible to all users, is the ability to view species distributions. With a growing list of species, you can quickly and easily get an idea of where certain crayfish are located and how widespread they are. Interested in invasive species and their range across continent? Just a few clicks away.

For those interested in digging the scientific literature, the platform offers a searchable database of research papers related to crayfish. Finding and accessing the original source of data has never been easier.

Researchers looking to model species distributions usually sick for amount of high-quality and accurate data on species occurrences. Our platform contains a wealth of crayfish distribution data, with layers specifically designed for describing aquatic habitats in the background. Once registered, you can extract desired dataset and use it to train your probabilistic models. You'll be pleasingly surprised by the variety of data we have, and soon you will realize that your research goals can reach higher levels.

We are in a permanent effort to pool resources and develop advanced modules for automated analysis, so that this platform can reach higher standards. However, in the meantime, you can also do something very useful, especially if you are a crayfish enthusiast and already have published data, older or very new one. Or you just want to make an effort to centralize publications from your country or region that you do not see indexed here yet. Your contribution are welcomed and really can make the difference, the entire platform becoming even more valuable. And definitely, will be forever appreciated by the community of astacologists.


Important! World of Crayfish can be a repository option for your datasets involving distributions. We can provide accession codes for your unpublished records. Contact us for more details.
