Otolith microchemistry analysis revealed that bycatch of European shads, allis shad Alosa alosa and twaite shad Alosa fallax , in western Iberian commercial fisheries removes individuals from a wide array of natal origins, with the most abundant source rivers suffering the heaviest losses. Spatial variation in bycatch risk was evident: Specific marine areas exhibited high natal origin diversity, reflecting complex dispersal. A...

While most anuran species are highly vocal, few of them seem to be endowed with a complex call repertoire. Odorrana tormota , combines a remarkable vocalization complexity with auditory sensitivity over an extended spectral range spanning from audible to ultrasonic frequencies. This species is also exceptional for its ability to modify its middle ear tuning by closing the Eustachian tubes (ET). Using scanning laser Doppler vib...

Key Message Several Fusarium wilt resistance genes were discovered, genetically and physically mapped, and rapidly deployed via marker-assisted selection to develop cultivars resistant to Fusarium oxysporum f. sp. fragariae , a devastating soil-borne pathogen of strawberry . Abstract Fusarium wilt, a soilborne disease caused by Fusarium oxysporum f. sp. fragariae , poses a significant threat to strawberry ( Fragaria $$\times$$...

Research, largely focused on academia, has shown demographic differences in perceptions and experiences of workplace culture in science fields, including natural resources. Less is known about experiences of those working for government institutions. This study examined relationships between demographic characteristics (gender, scientific discipline, years as a scientist), experiences of discrimination or harassment, and perce...

Approximately 6% of the freshwater living northern straight‐mouth nase Pseudochondrostoma duriense in two Spanish rivers had attached post‐metamorphic sea lamprey Petromyzon marinus . Minimum prey size was 16·1 cm fork length and 56·3 g mass. The condition factor of attacked P. duriense was 16% lower than that of unattacked conspecifics.
