Effects of the Invasive Round Goby on Swedish Recreational Fishing Values

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The round goby, an invasive fish from the Black and Caspian Seas, has spread to Swedish waters, threatening recreational fisheries. We modeled impacts on the future recreational fishery in Sweden using data from a recreational fishing survey, and estimated effects of the round goby on other fish species. Values attached to recreational fishing

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Wild boar feeding habits before versus after wolf recolonization

open access: yesJournal of Zoology, EarlyView.
By analyzing wild boar diet before and after wolf recolonization in a Mediterranean coastal area, we evaluated whether the return of wolves facilitated feeding on deer carcasses by wild boar. While deer hair was never reported in samples of wild boar feces in 1991–1994, we found it in c.

Signal crayfish are susceptible to crayfish plague infection under physiological challenge

open access: yes, 2013
The carrier status and possible elevated resistance against the crayfish plaque (Aphanomyces astaci) of signal crayfish has been speculated for several decades. We studied the responses of two signal crayfish (Pacifastacus leniusculus) populations against the virulent crayfish plague infections under laboratory conditions.
