DOI: DOI: 10.1086/703417. 3 2. ABSTRACT Invasive species often have a significant impact on the biodiversity of ecosystems and the species native to it. One of the worst invaders worldwide is Aphanomyces astaci, the causative agent of the crayfish plague, an often fatal disease to crayfish species not native to North America. Aphanomyces astaci originates from North America and was introduced to Europe in the midst of the 19th century. Since then, it spread throughout Europe diminishing the European crayfish populations. The overall aim of this thesis was to evaluate the threat that A. astaci still poses to European crayfish species more than 150 years after its introduction to Europe. In the first part of the thesis, crayfish specimens, which are available in the German pet trade, were tested for infections with A. astaci. Around 13% of the tested crayfish were clearly infected with A. astaci. The study demonstrated the potential danger the pet trade poses for biodiversity through the import of alien species and their potential pathogens, in general. In the second part of the thesis, the A. astaci infection prevalence of crayfish species in wild populations in Europe was tested. While the stone crayfish, Austropotamobius torrentium, showed high susceptibility to different haplogroups of A. astaci, the narrow-clawed crayfish, Astacus leptodactylus, was able to survive infections, even by haplogroup B, which is considered to be highly virulent. In the last part of the thesis, A. astaci was traced back to its original distribution area of North America. While the crayfish plague never had such a devastating effect on crayfish in North America as it had in Europe, the reasons for the success of invasive crayfish within North America are not yet fully understood. It is possible that A. astaci increases the invasion success of some crayfish species. Several populations of the rusty crayfish, Orconectes rusticus, in the Midwest of North America were confirmed to be infected with A. astaci and a new genotype was identified, possibly indicating that each crayfish host is vector of a unique A. astaci genotype, even in North America. Overall, the present thesis provides evidence that A. astaci is still a major threat to the crayfish species indigenous to Europe. Crayfish mass mortalities still occur in susceptible crayfish species like A. torrentium even 150 years after the first introduction of A. astaci. While there are some indications for increased resistances through processes of co-evolution, the continuous introduction

  • CRAYFISH IDENTIFICATION with DICHOTOMOUS KEYS As The
    CRAYFISH IDENTIFICATION WITH DICHOTOMOUS KEYS As the name implies, a dichotomous key includes a series of paired choices called couplets. Each couplet contains alternative identification characteristics that allow you to advance step by step through the key, until you reach an endpoint (species). Once you reach your endpoint, read through the associated species account, and review the range map to make sure it fits what you found. If after reviewing the account and the map, you think you reached the species in error, go back to the key, and think about where you had to make a difficult decision on which way to proceed in the key. Then, try the opposite choice to see if it leads you to a better answer. When starting out, using dichotomous keys can be frustrating. Sometimes the characteristics presented in the key are straightforward, while other times the differences are extremely subtle. Seldom will every characteristic presented in a couplet match your specimen exactly. Be patient, choose the “best” answer, and as mentioned above, be ready to try alternative routes within the key. Keep in mind also that the photo included within a given species account represents a single, clean individual. There will often be variability in color and size depending on the sex and age class of the individual you are attempting to identify. You will see a good example of this when you are using one of the keys where Cambarus latimanus is present. The common name of this species is Variable Crayfish, and the name is fitting. This species is so variable that in some keys it appears in two places.

They are closely related to the sexually reproducing slough crayfish, Procambarus fallax, which is native to the southeastern United States. Previous studies have shown that marbled crayfish are morphologically very similar to P. fallax. However, different fitness traits, reproductive incompatibility and substantial genetic differences suggest that the marbled crayfish should be considered an independent species. This article provides its formal description and scientific name, Procambarus virgin- alis sp. nov. Key words: parthenogenesis, annulus ventralis, genetic analysis, mitochondrial DNA Introduction Marbled crayfish were first described in 2001 as the only known obligatory parthenogen among the approximately 15,000 decapod crustaceans (Scholtz et al., 2003). The animals were first described in the German aquarium trade in the late 1990s (Scholtz et al., 2003) and became widely distributed in subsequent years under their German name "Marmorkrebs". Stable populations have developed from anthropogenic releases in various countries including Madagascar, Germany, Czech Republic, Hungary, Croatia and Ukraine (Chucholl et al., 2012; Jones et al., 2009; Kawai et al., 2009; Liptak et al., 2016; Lokkos et al., 2016; Novitsky & Son, 2016; Patoka et al., 2016).

  • Marbled Crayfish (Marmokrebs) Control in Ohio
    OHIO DIVISION OF WILDLIFE Marbled Crayfish (Marmokrebs) Control in Ohio Injurious Aquatic Invasive Species (IAIS) are animals that cause or are likely to cause damage or harm to native ecosystems or to commercial, agricultural, or recreational activities that are dependent on these ecosystems. The Ohio Department of Natural Resources, Division of Wildlife has the authority to establish an active list of Ohio IAIS high-risk species through a risk-analysis process to evaluate non-native candidate species via Ohio Administrative Code 1501:31-19-01. Listed species are unlawful to possess, import, or sell unless dead and/or preserved. Prevention: Risk Reduction State and federal partners are working to eliminate the risk of invasive Marbled Crayfish (also known as Marmokrebs) by preventing this Ohio-listed IAIS from public possession and sales in Ohio and to prevent their introduction and spread in Ohio waters and fish culture facilities. Background Marbled Crayfish (Marmokrebs) • Adult size – 10 to 13 cm (4 to 6 inches). Procambarus fallax f. virginalis • Grow and mature rapidly in captivity. • Not native to Ohio, Great Lakes or Ohio River watersheds. • Not known to occur in the wild, except through accidental or purposeful release. • Mostly a cultured species in the North American and European pet trade. “Marmokrebs” is its European common name. An all-female species, it reproduces asexually through parthenogenesis. • Closely related to the slough crayfish, Procambarus fallax, native to Florida and southern Georgia. Current Status, Management, Control and Exclusion in Ohio • Marbled crayfish have been defined as a high-risk IAIS in Ohio as they are non-native, adult females have a high reproductive capacity, and they can displace native crayfish.

Jimenez and Zen Faulkes Department of Biology, The University of Texas-Pan American, 1201 W. University Drive, Edinburg, TX 78539, USA. Email: [email protected] Abstract Marmorkrebs are parthenogenetic marbled crayfish whose origins are unknown. They have potential to be a model organism for biological research because they are genetically uniform, and to be an invasive pest species. Maintaining self-sustaining breeding colonies is a key element of most successful model organisms. We tried to find the best conditions for establishing and maintaining a Marmorkrebs breeding colony for research. Marmorkrebs can be bred in a compact tank system originally designed for zebrafish.

  • Ecological Effects of Predator Information Mediated by Prey Behavior
    ECOLOGICAL EFFECTS OF PREDATOR INFORMATION MEDIATED BY PREY BEHAVIOR Tyler C. Wood A Dissertation Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY May 2020 Committee: Paul Moore, Advisor Robert Green Graduate Faculty Representative Shannon Pelini Andrew Turner Daniel Wiegmann ii ABSTRACT Paul Moore, Advisor The interactions between predators and their prey are complex and drive much of what we know about the dynamics of ecological communities. When prey animals are exposed to threatening stimuli from a predator, they respond by altering their morphology, physiology, or behavior to defend themselves or avoid encountering the predator. The non-consumptive effects of predators (NCEs) are costly for prey in terms of energy use and lost opportunities to access resources. Often, the antipredator behaviors of prey impact their foraging behavior which can influence other species in the community; a process known as a behaviorally mediated trophic cascade (BMTC). In this dissertation, predator odor cues were manipulated to explore how prey use predator information to assess threats in their environment and make decisions about resource use. The three studies were based on a tri-trophic interaction involving predatory fish, crayfish as prey, and aquatic plants as the prey’s food. Predator odors were manipulated while the foraging behavior, shelter use, and activity of prey were monitored. The abundances of aquatic plants were also measured to quantify the influence of altered crayfish foraging behavior on plant communities. The first experiment tested the influence of predator odor presence or absence on crayfish behavior.
