The role of salmonid fishes in conservation of the endangered freshwater pearl mussel (Margaritifera margaritifera)
2016
The abundance of freshwater pearl mussels (Margaritifera margaritifera) has declined widely during the past century, and new conservation initiatives are needed. This thesis focused on the relationship between M. margaritifera and its salmonid host required for reproduction of this species. First, by exposing fish experimentally to glochidium larvae of M. margaritifera, different M. margaritifera populations were shown to demonstrate strong differences in their ability to parasitize different salmonid species. Atlantic salmon was clearly a better host for mussels in large river channels, whereas in small headwater tributaries brown trout was the best, or the only suitable, host. These findi…

Carlos Castilla e il "Teatro Geografico antiguo y moderno del Reyno de Sicilia" (1686)
2008
Il saggio fornisce notizie inedite sulla figura di Carlos Castiglia, sconosciuto “editor” del “Teatro Geografico Antiguo y Moderno del Reyno del Sicilia”, il prezioso codice cartografico del 1686, oggi custodito a Madrid, presso l’Archivo General y Biblioteca del Ministerio de Asuntos Exteriores y de Cooperacion; tali notizie permettono di avanzare ulteriori ipotesi sull’oscura genesi dell’opera, sulle aspettative del committente e sul ruolo del suo curatore. The paper presents unpublished information on the person of Carlos Castilla, unknown “editor” of the “Teatro Geografico Antiguo y Moderno del Reyno del Sicilia” the precious chart Code of 1686, now housed in Madrid, at the Archivo Gene…
Development and validation of a bioenergetics model for juvenile and adult burbot
2003
Oxygen consumption of juvenile and adult burbot Lota Iota was measured in an intermittent-flow respirometer to determine the effect of temperature and fish body mass on metabolic rate. These results were combined with data from earlier experiments and the 'Wisconsin bioenergetics' model was constructed. The model was validated under laboratory conditions by comparing observed and predicted food consumption and growth of burbot fed on dead vendace Coregonus albula. There was a good correspondence between observed and estimated growth and food consumption under experimental conditions: the mean absolute per cent errors of growth and food consumption were 4.8 and 24.0%. Estimated values with t…
Cryptic microgeographic variation in responses of larval Atlantic cod to warmer temperatures
2021
AbstractAlthough temperature is known to drive species dynamics and distributions, our understanding of the extent to which thermal plasticity varies within species is poor. Differences in plasticity can arise through local adaptation to heterogeneous environments, hybridization, and the release of cryptic genetic variation in novel environments. Here, wild Atlantic cod (Gadus morhua) from contrasting environments inside and outside of a fjord system in southern Norway spawned freely in a semi-natural laboratory environment, generating pure crosses and reciprocal hybrids. A common-garden rearing experiment of the larvae at 6°C, 9.5°C, and 13°C revealed cryptic genetic variation in thermal r…
Taxonomy and palaeobiogeography of the Cenozoic Euro-Mediterranean rissoid gastropod Galeodinopsis and its relationship with close genera
2014
The investigation of the Late Paleogene to Late Neogene species of rissoid gastropod Galeodinopsis in the Euro-Mediterranean area has supported the hypothesis that this genus is an intermediate form between two well-known rissoids, Alvinia and Manzonia. We recognized four species of Galeodinopsis: G. biangulata, G. germanica sp. nov., G. semperi (new name for Rissoa duboisii), and G. tiberiana. The oldest (very Late Eocene/Oligocene) representatives of Galeodinopsis, G. biangulata, and G. semperi, share similar shell shape and microsculpture with Alvinia. This suggests that Galeodinopsis originated from some Eocene species related to Alvinia. The new species represents the first occurrence …
