Following their first appearance, the invasive fishes Pseudorasbora parva and Perccottus glenii have been in Lithuania for several decades. However, until recently, information relating to their distribution and secondary spread was limited. For this reason, suitable habitats for these fish species were surveyed for their presence across the entire country. Additionally, all previously reported records on the presence of these species were summarized. Results revealed P. glenii to be widely distributed within the country with abundant populations in habitats suitable for the species. The recent distribution of P. parva is restricted to only a few water bodies. It was shown that both species are associated with human mediated transfer, while no natural dispersal of these invasive species was observed. The results of this study suggest that the invasion of Lithuanian inland waters by P. parva and P. glenii is still ongoing, and their occurrence in numerous water bodies, which are still devoid of these species, now seems probable. Demonstrated vectors of P. parva and P. glenii introductions in Lithuania highlight the importance of controlling and screening human activities related to aquaculture, recreational angling and the ornamental fish trade in order to restrict further P. glenii and P. parva expansion in this region.
If any issue attracts the attention of the legal public in the area of judicial review of decisions of health insurance companies, it is primarily an inconsistent attitude of administrative courts to decisions on reimbursement of otherwise non-reimbursed health services pursuant to Sec. 16 of Act No. 48/1997 Coll. on Public Health Insurance. On the basis of suggestions arising primarily from the decisions of the Municipal Court in Prague and the Supreme Administrative Court, or possibly the Constitutional Court, this paper notes three areas of problems, namely the term decision of the administrative authority pursuant to Sec. 65 of the Code of Administrative Justice, participation in the proceedings for an action against a decision of an administrative authority, and finally a procedural succession. The purpose is not to give a definitive solution to these problems, but to contribute to the discussion with further arguments, and also to place the problem in the wider context of legislation and case law. and Poutá-li nějaká otázka pozornost právnické veřejnosti v oblasti soudního přezkumu rozhodnutí zdravotních pojišťoven, jde především o nejednotný postoj soudů ve správním soudnictví k rozhodnutím o úhradě jinak nehrazené zdravotní služby podle § 16 zákona č. 48/1997 Sb., o veřejném zdravotním pojištění. Tento příspěvek si na základě podnětů plynoucích především z rozhodnutí Městského soudu v Praze a Nejvyššího správního soudu, popřípadě též soudu Ústavního, všímá tří okruhů problémů, a sice pojmu rozhodnutí správního orgánu ve smyslu § 65 odst. 1 s. ř. s., účastenství v řízení o žalobě proti rozhodnutí správního orgánu, a konečně procesního nástupnictví. Účelem není podat definitivní řešení těchto problémů, ale přispět do diskuse dalšími argumenty, a také zasadit problém do širšího kontextu právní úpravy a rozhodovací praxe.
Specimens of Neoechinorhynchus (Neoechinorhynchus) poonchensis sp. n. are described from Schizothorax richardsonii (Gray) in the Poonch River, Jammu and Kashmir. Specimens are thick-walled with dissimilar dorsal and ventral para-receptacle structures, anteriorly manubriated hooks, two giant nuclei in each lemniscus and many subcutaneousy. The lemnisci barely overlap the larger anterior testis, the cement gland has eight giant nuclei, and the seminal vesicle is large with thin walls. The vagina is unremarkable but the long uterus is made up of four specialised regions. Neoechinorhynchus rigidus (Van Cleave, 1928), resembles N. poonchensis sp. n. It is distinguished from N. poonchensis sp. n. by having smaller trunk, proboscis, and male reproductive structures, equal testes, unequal lemnisci with three giant nuclei each, and much larger anterior proboscis hook (130 μm in males) than that originally described by Van Cleave (1928) (70 μm in a female). Anterior hook length alone is sufficient to conclude that the N. rigidus of Datta (1937) is not the same species as the N. rigidus of Van Cleave (1928). Van Cleave's (1928) species remains valid and that of Datta (1937) is considered a different species named Neoechinorhynchus pseudorigidus sp. n., herein. Micropores of N. poonchensis sp. n. have variable distribution in different trunk regions and the Energy Dispersive X-ray analysis demonstrated higher levels of sulfur and lower levels of calcium and phosphorus. Sequences of the 18S rDNA gene from nuclear DNA, and cytochrome c oxidase subunit I (cox1) from mitochondrial DNA of N. poonchensis sp. n. were amplified and aligned with other sequences available on GenBank. Maximum likelihood (ML) and Bayesian inference (BI) analyses inferred for 18S rDNA and cox1 showed that N. poonchensis sp. n. was nested in a separate clade.
Efficient and systematic survey methods are essential for wildlife researchers and conservationists to collect accurate ecological data that can be used to make informed conservation decisions. For endangered and elusive species, that are not easily detected by conventional methods, reliable, time- and cost-efficient methodologies become increasingly important. Across a growing spectrum of conservation research projects, survey outcomes are benefitting from scent detection dogs that assist with locating elusive species. This paper describes the training methodology used to investigate the ability of a scent detection dog to locate live riverine rabbits (Bunolagus monticularis) in their natural habitat, and to determine how species-specific the dog was towards the target scent in a controlled environment. The dog was trained using operant conditioning and a non-visual methodology, with only limited scent from roadkill specimens available. The dog achieved a 98% specificity rate towards the target scent, indicating that the dog was able to distinguish the scent of riverine rabbits from the scent of other lagomorph species. The dog has already been able to locate ten of these elusive individuals in the wild. The training method proved successful in the detection of this critically endangered species, where scent for training was only available from deceased specimens.
Two hypogean species of genus Triplophysa are herein described from two subterranean tributaries of the River Yangtze drainage in Guiyang City, Guizhou Province, China. Triplophysa wudangensis, new species, can be distinguished from its congeners by the combination of the following characters: eye reduced, with diameter 5.1-6.5% HL; interorbital width 33.1-35.8% HL; body scaleless; lateral line complete; posterior chamber of air bladder degenerated; anterior nostril with elongated barbel-like tip; distal margin of dorsal fin truncate; dorsal fin with 7, anal fin with 5, and caudal fin with 14 branched fin rays; vertebrae 4 + 34. Triplophysa qingzhenensis, new species, can be distinguished from its congeners by the combination of the following characters: eye reduced, with diameter 2.1-4.4% HL; interorbital width 25.1-30.4% HL; body scaleless; lateral line complete; posterior chamber of air bladder degenerated; anterior nostril with elongated barbel-like tip; distal margin of dorsal fin truncate; dorsal fin with 7-8, anal fin with 5, and caudal fin with 14 branched fin rays; vertebrae 4 + 36. Molecular phylogenetic analysis supported the validity of these two new species and indicated their close relationship with Triplophysa rosa.
A detection dog and handler team were used to recover scats in areas newly colonized by wolves outside the Alpine mountains of France between October 2018 and May 2019. Survey areas were classified as occupied by a resident wolf pack (WP) or dispersers (no-WP). The efficiency of monitoring by a targeted dog-handler team was compared to opportunistic monitoring by trained observers. Use of the detection dog allowed up to 99.6% time savings relative to monitoring by trained observers. Wolf scats found by the dog represented 82.1% of genetically confirmed samples in the 12 sample units (each being 10 × 10 km) monitored by both trained observers and the dog-handler team. Occupancy modelling was used to estimate wolf detection probabilities. Ten kilometres of survey with the dog were required to reach a 98% detection probability in WP territories and 20 km to reach 96% in no-WP areas. By contrast, two years of opportunistic monitoring by trained observers were required to obtain a 90% and 76% probability of detecting wolves in WP and no-WP areas, respectively. The use of the detection dog via dog-team surveys greatly increased the collection of viable samples for genetic analysis and individual genotype identification. Our study offers further confirmation that dog-handler teams can be very effective at locating scats from target carnivores, to supplement or complement human search efforts.
