Abstract The redclaw crayfish ( Cherax quadricarinatus ; hereafter redclaw), native to northern Australia and southern New Guinea, is among the largest freshwater decapods. It matures early considered highly prolific as females may lay over one thousand eggs in a single clutch. Despite generally preferring slow‐moving streams its range, it has wide environmental tolerance, making capable of establishing populations when introduced range other conditions habitats. These biological ecological...
ABSTRACT Standardised terminology in science is important for clarity of interpretation and communication. In invasion – a dynamic rapidly evolving discipline the proliferation technical has lacked standardised framework its development. The result convoluted inconsistent usage terminology, with various discrepancies descriptions damage interventions. A therefore needed clear, universally applicable, consistent to promote more effective communication across researchers, stakeholders,...
Businesses in the pet trade collect and transport many aquatic species around globe, some of these individuals are released into new habitats. Some jurisdictions have introduced laws intended to regulate this trade, but regulations rarely had desired effects. Laws regarding pets often poorly communicated, enforced, not aligned with hobbyists' beliefs. Consequently, may increase number unwanted introductions instead decreasing them. A significant change approach is needed, involving far...
Cherax pulverulentus sp. nov. is a moderately-sized burrowing freshwater crayfish endemic to the streams west of Ayamaru Lake in Bird's Head Peninsula (Framu Subdistrict, Southwest Papua Province), Indonesian part New Guinea. Although this species has been exploited ornamental aquarium trade at least for 21 years, it not formally named until now. Its commonly used commercial names pet are: "Hoa Creek", "Irian Jaya", or "Blue Moon" crayfish, but these are also other more bluish pinkish...
Abstract Freshwater biodiversity is globally threatened by various factors while severe weather events like long-term droughts may be substantially devastating. In order to remain in contact with the water or stay a sufficiently humid environment at drying localities, ability withstand desiccation dwelling hyporheic zone, particularly through vertical burrowing crucial. We assessed of three European native and five non-native crayfish as models survive construct burrows sandy-clayey...
Cherax acherontis n. sp., is a crayfish endemic to the submerged river Yumugima in Hagepma/Jugurama cave New Guinea Highlands, Jayawijaya Regency, Papua Province, Indonesia. This species first crayfish from Southern Hemisphere. The new most similar monticola. Both can be easily distinguished by certain morphological characteristics, which demonstrate C. sp. valid species.
Abstract Numerous freshwater crayfish species are known to become successful invaders when introduced new territories. One of the most invasive in this group is red swamp crayfish, Procambarus clarkii (Girard, 1852). In addition other characteristics facilitating its invasiveness, it also a vector plague, disease mostly lethal non‐North American origin. , at present widespread globally, popular many countries both for human consumption and as an ornamental animal. An established population...
Abstract Modern ornamental fishkeeping is one of the most popular hobbies in world, with various known positive and also negative aspects including introduction non‐native species. Despite this fact, history first imports freshwater tropical fish species for purposes has never been deeply studied usually simplified. Here, we present comprehensive review reported period early sector aquaculture, ending end First World War. Moreover, total number kept updated, a forecast future. We summarised...
The import of aquarium animals has been increasing worldwide in recent years. Despite its contribution to world trade and the economy, this also comprises one main pathways for introduction non-indigenous animals. In past decade, crayfish become a popular pet as well potential threat environment upon escape or release. Since Czech Republic is world's leading importer, exporter, producer aquatic ornamental animals, we prepared detailed analysis imports. present paper provides complete list...
A new species of highly troglobitic cockroach, Nocticola baumi n. sp., is described from limestone caves Papua Province, Indonesia. The the first reported in New Guinea island and differs other known spp. by combination following characters: compound eyes ocelli absent, tegmina fully developed extending beyond abdomen, hind wings legs extremely long. discovery genus on bridges gap between Oriental Australian distribution stresses unknown diversity genus.
For management strategies aimed at biological invasions, a detailed survey of the general public's knowledge is crucial. this purpose, our present study to (i) investigate level comprehension regarding (ii) assess ability responders discriminate between invasive and native species, (iii) evaluate conservation support. Increased awareness invasions on part respondents positively influences willingness protect fish crayfish species not their counterparts. Higher identification scores by...
The pet-turtle market has grown in recent years and become an important pathway for the introduction of alien species Europe. import Trachemys scripta elegans been banned by European Commission Regulation due to its species' expanding territory negative impact on native species. Since demand from hobby breeders persists, however, blocking imports this popular subspecies opens up possibility other potentially invasive turtles. We determined those turtle most common pet trade within Czech...
The private stocking of ornamental crayfish in garden ponds was discussed previous studies, but there is a lack detailed analysis for better understanding this introduction pathway. Czech Republic one leading EU countries trade with and are popular among people. keepers the country were interviewed by self-administered questionnaire to gather data about principal characteristics information breeding that interest conservation managers. Besides releasing into ponds, alarming illegal behavior...
Abstract The pet trade has been responsible for many introductions of non‐native species. Freshwater ornamental plants and animals originating from the are stocked to garden ponds. present survey focused on awareness behaviour related biological invasion risks companies that designed, built, A representative number ( n = 124) (commercial pond architects builders) in Czech Republic were surveyed regarding offer non‐native, invasive threatened native was conducted over entire warm period (from...
Biological invasions are increasingly recognized ecological and economic threats to biodiversity projected increase in the future. Introduced freshwater crayfish particular protruding invaders, exerting tremendous impacts on native ecosystem functioning, as exemplified by North American spiny-cheek, signal red swamp well Australian common yabby. The marbled is among most outstanding invaders due its parthenogenetic reproduction combined with early maturation high fecundity. As their...
Freshwater crayfish are amongst the largest macroinvertebrates and play a keystone role in ecosystems they occupy. Understanding global distribution of these animals is often hindered due to paucity distributional data. Additionally, non-native introductions becoming more frequent, which can cause severe environmental economic impacts. Management decisions related their habitats require accurate, up-to-date data mapping tools. Such currently patchily distributed with limited accessibility...

ABSTRACT The ornamental pet trade has emerged as one of the most important pathways for introduction non‐native aquatic species. In last two decades, freshwater crayfish have become a popular group, with numerous populations established through this way, including some North American red swamp Procambarus clarkii (Girard, 1852). Whilst routes aquaculture‐derived been identified molecular methods and historical documents, obtaining traceability in market is often more challenging. We analysed...
ABSTRACT Ornamental aquaculture and fishkeeping are very popular with millions of enthusiasts worldwide. The number newly imported fish species for ornamental purposes grew slowly from World War I until the 1980s. It then exponentially increased now more than 7900 a large scientifically undescribed morphotypes. Here we present first comprehensive review freshwater brackish importations during boom keeping at turn Millennium discuss this cultural socio‐economic lens in European context....
An increasing number of non-indigenous crayfish species (NICS) apparently pet trade origin have become established particularly in Europe.
