Deforestation and forest degradation are key drivers of biodiversity loss and global environmental change. Ecosystem restoration is recognized as a global priority to counter these processes. Forest restoration efforts have commonly adopted a predominantly ecological approach, without including broader socioeconomic variables and the characteristics of the rural context.

Article Synopsis
- Computational neurosurgery combines artificial intelligence and computational modeling to enhance the diagnosis and treatment of neurosurgical conditions, aiming to advance clinical neurosciences.
- The field seeks to integrate ethical considerations to ensure that the use of AI is conducted responsibly and prioritizes patient care, ultimately aiming to prevent errors in treatment.
- This initiative serves as a guide for practitioners, ethicists, and scientists in the application of ethical standards within computational neurosurgery.
Background: The dilemma of neuro-oncological surgery involving suspected eloquent cortex is to maximize the extent of resection while minimizing neurological morbidity, referred to as the "onco-functional balance." Diffuse lower-grade gliomas are capable of infiltrating or displacing neural function within cortical regions and subcortical white matter tracts, which can render classical anatomic associations of eloquent function misleading.
Observations: This study employed presurgical navigated transcranial magnetic stimulation (nTMS) to determine the motor eloquence of a diffuse lower-grade glioma at the superior frontal gyrus extending and intrinsic to the primary motor cortex in a 45-year-old female.
Background And Importance: The surgical management of intramedullary spinal cord tumours (IMSCT) poses inherent risk to neurologic function. Direct-wave (D-wave) monitoring is routinely reported to be a robust prognostic measure of spinal cord function via midline recording within the epidural or intradural space in a cranial-caudal montage. We explored the feasibility of bilateral epidural D-wave monitoring with routine evoked potentials in promoting safe and maximal resection in a patient with diminished midline D-wave baselines associated with an eccentric intramedullary cervical astrocytoma.

- Top carnivores, like Tasmanian devils, influence ecological communities through competition and predation, but human habitat disturbance also plays a significant role.
- A study analyzing stable isotopes showed that the decline of Tasmanian devils affected both their own and spotted-tailed quolls' ecological niches, with narrower niches observed in human-altered environments.
- Overall, the research found that anthropogenic disturbances impact mammalian carnivore niches more than the decline of top carnivores themselves, suggesting a complex interplay between these factors.
