Purpose Of Review: In response to the COVID-19 pandemic, there has been a remarkably accelerated development of vaccines worldwide. However, an effective distribution system is crucial for vaccination at a national level. Ecuador was one of the first Latin American countries to be most severely affected by the pandemic.

The range of hosts exploited by a parasite is determined by several factors, including host availability, infectivity and exploitability. Each of these can be the target of natural selection on both host and parasite, which will determine the local outcome of interactions, and potentially lead to coevolution. However, geographical variation in host use and specificity has rarely been investigated.

Article Synopsis
  • Organisms like the brown-lipped banded snail are good at showing how climate change affects them and how they might evolve quickly.
  • Researchers looked at shell colors and patterns of over 9,000 snail populations in Europe to see if their features changed due to warming temperatures over the last 50 years.
  • They found that while some colors stayed common, there was a surprising drop in 'Unbanded' shells, showing that other factors, like changes in predators and habitats, also influence how these snails adapt.

Habitat fragmentation may interrupt trophic interactions if herbivores and their specific parasitoids respond differently to decreasing connectivity of populations. Theoretical models predict that species at higher trophic levels are more negatively affected by isolation than lower trophic level species. By combining ecological data with genetic information from microsatellite markers we tested this hypothesis on the butterfly Maculinea nausithous and its specialist hymenopteran parasitoid Neotypus melanocephalus.
