Experimental approach for studying structural changes in axonal membrane upon nerve excitation [PDF]

open access: yes, 2011
The Hodgkin and Huxley (HH) model of action potential has become a central paradigm of neuroscience. Despite its ability to predict action potentials with remarkable accuracy, it fails to explain several biophysical findings related to the initiation and

Understanding the threats posed by non-native species: public vs. conservation managers. [PDF]

open access: yes, 2013
Public perception is a key factor influencing current conservation policy. Therefore, it is important to determine the influence of the public, end-users and scientists on the prioritisation of conservation issues and the direct implications for policy ...

THE DISPERSION OF THE APHANOMYCES ASTACI-CARRIER PACIFASTACUS LENIUSCULUS BY HUMANS REPRESENTS THE MAIN CAUSE OF DISAPPEARANCE OF THE INDIGENOUS CRAYFISH AUSTROPOTAMOBIUS PALLIPES IN NAVARRA

open access: yesKnowledge and Management of Aquatic Ecosystems, 2006
The tendency of population decline of the indigenous crayfish, Austropotamobius pallipes, in Navarra was reduced by the implementation of a plan of restoration in 1996. Recently, a new drop in population numbers has been noticed.

Colonization and dispersal rates of two non-native crayfish species (Pacifastacus leniusculus and Procambarus clarkii) in NE Portugal [PDF]

open access: yes, 2010
In Europe, a generalized regression of the native crayfish was observed during the past decades. Simultaneously, several non-native species spread in most countries.

Assessing the invasion potential of non-native branchiobdellidans: experimental studies of survival, reproduction and competition [PDF]

open access: yes, 2017
The impact of invasive species on the recipient ecosystem can be strongly influenced by the presence of associated symbionts. It is therefore important to evaluate the likelihood of co-introduced symbiont establishment, and this requires an understanding

BIOCIDE TREATMENT OF PONDS IN SCOTLAND TO ERADICATE SIGNAL CRAYFISH

open access: yesKnowledge and Management of Aquatic Ecosystems, 2006
This trial aimed to eradicate illegally introduced signal crayfish Pacifastacus leniusculus in the North Esk catchment, Scotland. Sites treated were (1) an isolated gravel-pit (c. 9,000 m3), with crayfish present for 6 years; (2) three dammed ponds, (c.
