Climate change has caused various habitats to change around the world. Many life-forms are migrating or changing in order to survive the global temperature change. The species that specialize in what they eat, or may dwindle into extinction. However, species with the highest survival potential are the life-forms that are easily adaptable and willing to explore new options. Species such as weeds and pests are really good at adapting. Here are 6 species that have already made adaptations to the shifting climate.
In Alaska, there is a pink salmon population that has begun its migration trek two weeks earlier than usual. Pink salmon are a species that migrate from the Ocean and travel up fresh water streams to spawn. This migration has been ingrained right into their gene pool. However, a study on genetic and migratory data shows that the genetic marker for late migration has dropped significantly, meaning the salmon are now traveling earlier in their migration season. This mirrors the overall water temperature which have increased (0.03oCelsius/year) over the last 32 years. This study shows that the Salmon are migrating earlier to combat the rise in water temperatures.
These cute little creatures have two shades: brown, or light grey. However, due to milder winters in Finland, it has been noted that there’s been a significant increase of brown tawny owls which can camouflage better in a snow-less environment. While some might say this is survival of the fittest, the fittest are those who can survive in a warmer climate.
European Larger Banded Snails
Snails continuing to evolve in order to survive. There has been a distinct increase in light-colored shell snails. Snails with lighter coloured shells have a lower body temperature. This change has been noted in the Netherlands, where light coloured shell snails have become more dominant, even in shady environments where you would expect darker-coloured shell snails to prevail.
Quino Checkerspot Butterfly (Euphydryas editha quino)
This is an endangered species believed to be doomed because of climate change. However, these unique butterflies have defied the prediction of their extinction by migrating to hire altitudes and choosing a new plant to lay its eggs upon. This is according to research presented at the Butterfly’s Conservations seventh international symposium.
Pitcher Plant Mosquitos
These mosquitoes are known to hibernate in the colder months, but as temperatures are warming up, they have started hibernating later in the season.
The red squirrels in the Yukon are actually benefiting from the environmental change. The increasingly warm springs and dry weather are helping white spruce trees to produce more cones. As a result, it is supplying red squirrels with more to eat. The more females eat in the fall, the earlier they give birth in the spring. There has been a noticeable change in birthing season within this squirrel population.
