Performance of Cerrado lizards: a test of the center–periphery hypothesis
Ecography, EarlyView.The center–periphery hypothesis (CPH) states that species' demographic performance declines from the center towards the periphery of their geographic range due to increasingly suboptimal environmental conditions. We tested the predictions under the CPH using two lizard lineages with different activity patterns and distributions, taking lizard body ...

Ecography, EarlyView.Hawaii has experienced profound declines in native avifauna alongside the introduction of numerous bird species. While site‐specific population studies are common, landscape‐level analyses of avian population dynamics are rare, particularly in island ecosystems. To address this gap, we used a density surface model to create a spatio‐temporal projection

BMJ, 2010 #### Summary points The vegetative state may develop suddenly (as a consequence of traumatic or non-traumatic brain injury, such as hypoxia or anoxia; infection; or haemorrhage) or gradually (in the course of a neurodegenerative disorder, such as Alzheimer’s disease).

Persistent vegetative state [PDF]
The Lancet, 1997 SIR—Adam Zeman (Sept 13, p 795) is to be congratulated on his excellent discussion of the concept of persistent vegetative state (PVS). As he points out, this concept is based on a particular model of consciousness and wakefulness that has certain shortcomings.

Prognosis of the posttraumatic vegetative state [PDF]
Acta Neurochirurgica, 1988 Of 1373 patients who, following severe brain injury had been comatose for over 6 hours, 140 (10%) were in a vegetative state one month later. Fifty-nine regained consciousness but none of those aged over 40 became independent during the first year. Of those still in a vegetative state after 3 months, none became independent irrespective of age.

Ethics and the vegetative state
Neuropsychological Rehabilitation, 2005Before discussing ethical issues to do with patients in permanent (or persistent) vegetative state (PVS) it is necessary to address the foundational issue of whether PVS as a concept is able to provide a robust link to situations in the real world. The high reported rates of misdiagnosis and recovery in patients diagnosed as being in PVS casts doubt ...

Cognition in the Vegetative State
Annual Review of Clinical Psychology, 2012Awake but not aware: This puzzling dissociation of the two central elements of consciousness defines the vegetative state. Traditionally, this condition has been believed to imply a brain with preserved hypothalamic and brainstem autonomic functions but with no capacity for cortical cognitive processes.

The vegetative state is characterized by the absence of awareness, voluntary or otherwise purposeful behavioral responses to external stimuli, and communication in the severely brain damaged. It is thought to result from an anatomical/functional disconnection between the brainstem and cortex as a result of diffuse axonal damage/impairment.
