Neuroblastoma is the most common extra-cranial solid tumour in children. Over half of all high-risk cases are expected to succumb to the disease even after chemotherapy, surgery, and immunotherapy. Although the importance of MYCN amplification in this disease is indisputable, the mechanistic details remain enigmatic.

Populations of forest trees exhibit large temporal fluctuations, but little is known about the synchrony of these fluctuations across space, including their sign, magnitude, causes and characteristic scales. These have important implications for metapopulation persistence and theoretical community ecology. Using data from permanent forest plots spanning local, regional and global spatial scales, we measured spatial synchrony in tree population growth rates over sub-decadal and decadal timescales and explored the relationship of synchrony to geographical distance.

Background: Risk score calculators are a widely developed tool to support clinicians in identifying and managing risk for certain diseases. However, little is known about physicians' applied experiences with risk score calculators and the role of risk score estimates in clinical decision making and patient communication.

Methods: Physicians providing care in outpatient community-based clinical settings ( = 20) were recruited to participate in semi-structured individual interviews to assess their use of risk score calculators in practice.

Article Synopsis
  • Canopy gaps play an important role in supporting forest tree diversity, but studies often show mixed results regarding their impact.
  • Our research in a tropical forest in Panama revealed that while individual gaps have slightly higher sapling richness and density initially, these differences become indistinguishable over time.
  • However, when looking at multiple gaps collectively, there were significant increases in species richness and the presence of gap-specialized species, suggesting that gaps are crucial for enhancing overall tree diversity in forests.
