Input Sources and Properties of Position-Sensitive Oculomotor Fibres in the Rock Lobster, Panulirus Interruptus (Randall) [PDF]

open access: yes, 1972
Sets of head-up, head-down, eye-up and eye-down motor fibres were studied in the oculomotor nerve of the rock lobster. An eye-withdrawal fibre was also investigated.

Excitatory postsynaptic potentials in rat neocortical neurons in vitro. III. Effects of a quinoxalinedione non-NMDA receptor antagonist [PDF]

open access: yes, 1990
1. Intracellular microelectrodes were used to obtain recordings from neurons in layer II/III of rat frontal cortex. A bipolar electrode positioned in layer IV of the neocortex was used to evoke postsynaptic potentials.

Dimensions of dace dynamics: temporal variation in abundance and survival of an imperiled desert fish guide habitat restoration

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Desert fishes are vulnerable to anthropogenic environmental alterations that degrade habitat and reduce water availability, but these same fishes benefit from restoration actions that reverse the causes of decline. Ash Meadows speckled dace (Rhinichthys osculus nevadensis) is a federally endangered minnow endemic to the Mojave ...

Managing invasive alien crayfish in isolated water bodies: Evaluating control strategies for biodiversity conservation

open access: yesKnowledge and Management of Aquatic Ecosystems
Invasive alien crayfish pose significant threats to biodiversity in aquatic ecosystems. In isolated water bodies they impact local amphibian populations by predation, and altering water quality due to burrowing behaviour.

Diel turbidity cycles in a headwater stream: evidence of nocturnal bioturbation? [PDF]

open access: yes, 2016
Purpose: A small number of recent studies have linked daily cycles in stream turbidity to nocturnal bioturbation by aquatic fauna, principally crayfish, and demonstrated this process can significantly impact upon water quality under baseflow conditions ...

Blue plaque review series: Thomas Graham Brown: Before his time

open access: yesExperimental Physiology, EarlyView.
Abstract Thomas Graham Brown made a seminal discovery, published in 1911 while he was a Carnegie Fellow in the University of Liverpool laboratory of Nobel Prize winner Charles S. Sherrington. Working in cats, he showed that rhythmic ‘voluntary’ behaviour, such as stepping and, by inference, walking, does not result from a chain of reflex events, but ...

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 ...
