Rapid species turnover in tropical mountains has fascinated biologists for centuries. A popular explanation for this heightened beta diversity is that climatic stability at low latitudes promotes the evolution of narrow thermal tolerance ranges, leading to local adaptation, evolutionary divergence and parapatric speciation along elevational gradients. However, an emerging consensus from research spanning phylogenetics, biogeography and behavioural ecology is that this process rarely, if ever, occurs.

Current diabetes treatment guidelines and algorithms recommend an individualized approach to setting glycemic goals and selecting treatment. Although a single antihyperglycemic agent may be appropriate as the initial T2DM pharmacotherapy, the progressive nature of the disease due to declining pancreatic β-cell function will result in the vast majority of T2DM patients eventually requiring two or more antihyperglycemic agents.

- Long-distance migratory species, like the Grey-cheeked Thrush, are under pressure to migrate quickly and use stopover sites to refuel during their journey.
- A study in northern Colombia demonstrated that the birds can fly more than 3000 km, emphasizing the critical role of stopover sites in their migration strategy.
- The research indicates that fuel loads gained at these sites and the timing of departure significantly impact migration speed, potentially affecting the birds' overall fitness and survival, highlighting the importance of conserving these key fueling locations.
