Timing and magnitude of climatic extremes differentially elevate mortality but enhance recovery in a fish population.

The countervailing effects of disturbances (e.g., high mortality and enhanced recovery) on population dynamics can occur through demographic processes under rapidly increasing climatic extremes.

Concurrent OPA1 mutation and chromosome 3q deletion leading to Behr syndrome: a case report.

Background: Optic atrophy 1 (OPA1) gene mutations are associated with dominantly inherited optic neuropathy resulting in a progressive loss of visual acuity. Compound heterozygous or homozygous variants that lead to severe phenotypes, including Behr syndrome, have been reported rarely.

Case Presentation: Here, we present a 14-month-old boy with early onset optic atrophy, congenital cataracts, neuromuscular disorders, mental retardation, and developmental delay.
