Recent molecular analyses of the stone crayfish have revealed a high degree genetic diversity. The greatest diversity is found in western Balkans (Dinarides), where more than half known phylogroups exist relatively small geographical area, some them having smaller distribution range others. While Croatian and Slovenian parts Austropotamobius torrentium areal are well described, data from Bosnia Herzegovina (BA) lacking. Here we provide 13 different localities northwestern BA. We analysed two mtDNA markers results with total 12 MT-COI nine MT-16SrRNA haplotypes, majority novel haplotypes. Both genes confirmed presence discovery new group named VOJ. CSE phylogroup was most widespread restricted to Vrbas basin. first detection BAN BA indicates its wider connects previously isolated findings Croatia. 18 unique haplotypes as particular interest, but further studies needed clarify their exact relationship other lineages.

ABSTRACT The idle crayfish ( Austropotamobius bihariensis Pârvulescu, 2019), endemic to Romania's Apuseni Mountains, urgently requires a specific conservation plan. Due its recent description, efforts have been limited, highlighting the need for immediate and practical recommendations ensure protection. Over 13 years, field observations were conducted evaluate population trends identify threats following IUCN standards. Additionally, geospatial assessments predictive modelling employed estimate both optimal habitat current size under three distinct scenarios. primary identified include poor forest management, extreme drought, anthropogenic development riverbed alterations, all contributing declines in abundance. most severe impacts arise when these pressures converge at single site, compounded by chronic, low‐virulence plague infection (A‐haplogroup). total is estimated 31,150 (± 449.9 SE) individuals, with 1,163,754 m 2 of suitable habitat, which only 37.9% lies within protected areas realistic scenario. Poor water quality was found significantly reduce modelled size. In light findings, we propose series targeted actions tailored each area highlight importance extending measures beyond their boundaries. recommend implementing ‘ark sites’ concept regions ecological conditions, stable populations genetic diversity, safeguard species through effective management.

There is increasing concern that the effects of biological invasions may be magnified by other human-induced global changes. Here, we compare non-consumptive imposed invasive vs. native predators and how these (differential) responses to both predator types depend on warming prey latitude. We raised damselfly larvae from central- high-latitudes in incubators under two temperatures (current [20 °C] [24 °C]) further exposed them one three cues: noble (native), signal (invasive at latitudes) spiny-cheek but absent high crayfish. Growth rate increased central-latitude decreased high-latitude response The crayfish only reduced growth prey. Cues all species generally caused a higher net energy budget, warming. Our results demonstrated were able recognize novel (spiny-cheek crayfish) cue, revealed differential toward shared (signal crayfish). data provide rare support for change factors magnify impact predators.
