While recent evolutionary studies have focused on a few of these species, here we provide a comprehensive phylogenetic estimate of relationships among the species within the genus. We sequenced three mitochondrial gene regions (COI, 16S, and 12S) and one nuclear region (28S) from 40 species of the genus Euastacus, as well as one undescribed species. Using these data, we estimated the phylogenetic relationships within the genus using maximum-likelihood, parsimony, and Bayesian Markov Chain Monte Carlo analyses. Using Bayes factors to test diVerent model hypotheses, we found that the best phylogeny supports monophyletic groupings of all but two recognized species and suggests a widespread ancestor that diverged by vicariance.

  • Evaluating the Effects of Invasive Brown Bullhead Catfish (Ameiurus Nebulosus) on Kōura (Freshwater Crayfish, Paranephrops Planifrons) in Lake Rotoiti
    Evaluating the effects of invasive brown bullhead catfish (Ameiurus nebulosus) on kōura (freshwater crayfish, Paranephrops planifrons) in Lake Rotoiti A thesis submitted in partial fulfilment of the requirements for the degree of Master of Science (Research) in Biological Sciences at The University of Waikato by Laura Beverley Francis 2019 This thesis is dedicated to Margaret Francis, Tracey Wemyss and Margaret McQuarrie whom passed away peacefully during my studies. Gone but never forgotten. i Abstract Brown bullhead catfish (Ameiurus nebulosus) are opportunistic carnivores native to North America and were first detected in Te Weta Bay, Lake Rotoiti, in March 2016. A cordon was placed across the bay to try and contain catfish, but they had already established populations elsewhere. Spread of catfish in the lake raised concern for resident populations of freshwater crayfish or kōura (Paranephrops planifrons), which are of ecological and cultural significance to Māori. Given the limited knowledge of the potential impacts of catfish on native biota, this thesis aims to evaluate the effects of catfish on kōura in Lake Rotoiti. To do this, Bay of Plenty Regional Council (BOPRC) routine fyke netting data was used to explore species trends and relationships. A habitat survey was also conducted using whakaweku (bracken fern bundles) and fyke nets, to generate data on species’ habitat preferences and kōura metrics (e.g., sizes and sex ratios). In addition to fishing, kōura and catfish stomachs were dissected to determine diet. Potential food items of catfish were also collected for stable isotope analysis to estimate dietary overlap between catfish and kōura, and long-term resource acquisition.

  • A Review of Ecological Interactions Between Crayfish and Fish
    Knowledge and Management of Aquatic Ecosystems (2011) 401, 10 http://www.kmae-journal.org c ONEMA, 2011 DOI: 10.1051/kmae/2011024 Review A review of ecological interactions between crayfish and fish, indigenous and introduced J.D. Reynolds(1) Received January 17, 2011 Revised March 14, 2011 Accepted March 16, 2011 ABSTRACT Key-words: Crayfish (decapods) and fish are both long-lived large members of fresh- crayfish, water communities, often functioning as keystone species. This paper freshwater fish, reviews interactions between these, with emphasis on the European con- keystone text. Native crayfish and fish are in ecological balance, which may involve species, mutual predation, competition and sometimes habitat disturbance. This competition, balance is disrupted by range extensions and translocations of native predation, fish or crayfish into exotic situations. Some fish and crayfish have been translocation, translocated globally, chiefly from North America to other continents. Non- alien invasive indigenous crayfish species (NICS) may impact on native fish, just as in- species, troduced fish impact on indigenous crayfish species (ICS). Competition native species between ICS and NICS may result in making the former susceptible to various mechanisms of interaction with fish, indigenous or introduced. In Europe, long-established NICS – signals, spiny-cheek and red swamp crayfish – may occur in greater densities than ICS; they are more tolerant and aggressive and show more interactions with fish. More recent intro- ductions, still restricted in distribution, have not yet received enough study for their impacts to be assessed. Interactions between fish and crayfish in North and South America, Madagascar and Australasia are also explored. Mechanisms of interaction between fish and crayfish include mutual pre- dation, competition for food and spatial resources, food-web alteration and habitat modification.

In addition, the occurrence and placement of spermatophores on adult females is described from specimens inhabiting small brooks at Otaru and Hamamasu, Hokkaido, Japan, sampled from 1998 to 1999. The second stage juveniles left their mother permanently after some exploration behavior. In adult females, spermatophores were attached to the surface of the seminal receptacle (annulus ventralis), which is situated at the posterior margin of the seventh thoracic sternite. In C. japonicus the invagination of the annulus ventralis is not deep enough to hide the male spermatophores. Previous studies of the Astacidae reported that juveniles left their mother at the second stage, that spermatophores were attached to the surfaces of sternal plates of the last three pereopods, and that an annulus ventralis did not exist. In contrast, Cambaridae juveniles normally detach from the mother at the third stage, but they may detach and stay longer with the parent until the fourth stage.
