Will Climate Change Lead to the Extinction of Certain Species?
In the event of climate change, many species of animals could be in danger of going extinct. This article discusses some of the factors that can help predict if a particular population will be affected. It also discusses how climate change will affect different areas of the world.
A recent study examining 538 species and 581 sites in the wild has shown that the heat wave of November 2018 was the worst month since records were kept. Although many of the eponymous creatures were killed off by the heat, a handful of the more notable species were a bit better off. In fact, a mere 10 to 30 percent more water is needed to feed this particular group of creatures than was the case in the past. On a positive note, a new generation of grazers has helped to improve grazing rates in the long run. The one major blip in the long term plan is the extinction of many species such as the nipah and nipah. Similarly, a growing population of wolves has helped improve the quality of life for wolves in the wild. However, a resurgence of wolves and other strays has been accompanied by a resurgence of foxes. Likewise, the sexing of a female wolf has helped to increase resuscitation rates of male wolves, the latter of which is a must if repopulations are to continue.
While there is no denying the impact of climate change on humans, it is the animals themselves that have the most to lose. This is especially true in the Arctic where the aforementioned ice-dependent aforementioned polar bears are facing an apocalyptic future. Fortunately, there are a handful of novel solutions in the works to combat the apocalypse. For example, the aforementioned polar bears have been found to be breeding in a number of remote locations such as Alaska and Greenland where they once would have been omitted from the picture.
Sea level rise
If you’ve lived in coastal regions for any length of time, you’ve probably noticed some of the impacts of climate change. You may have seen wildfires, warmer temperatures, and more severe storms. However, you may not be aware of how some species are being affected by the changes.
There are hundreds of species being impacted by climate change. One study found that there are 10,967 species on the IUCN Red List that are threatened by climate change. The United States is home to 1,383 federally protected endangered species.
Sea level rise is one of the most significant threats to many of these species. In addition to the loss of habitat, sea levels threaten public infrastructure and coastal property.
Some species are already becoming extinct. Climate change is killing coral reefs and depleting nutrients. It has also caused changes in the biology of migratory songbirds. These changes affect species that are adapted to warm climates.
There are more than 100 species that depend on shallow coastal water for survival. Those that depend on freshwater are at higher risk, as are those that live in low-lying areas.
For example, the polar bear is experiencing population declines in Alaska. Whales, penguins, and seals are also at risk. They rely on krill, a primary food source, for their survival.
Rising seas also cause erosion. This damage can lead to the death of trees from the roots up. Other coastal areas are threatened by floods, and they are also vulnerable to damage from storms.
There are also effects that will affect the entire food chain, including marine ecosystems. Algal blooms are increasing. Ocean acidification is reducing krill populations. Increased sea-ice melt is threatening the Arctic Ocean.
Many of these effects are locked in due to historical emissions. But they are expected to get worse as the climate continues to change. Adaptation measures can minimize cascading impacts. Adaptation is crucial for species that are highly dependent on freshwater.
Adaptation can include measures that help people in the affected areas prepare for the risks of sea level rise. Taking action to prepare for coastal flooding can help reduce direct losses.
Human-wildlife conflict is a growing problem worldwide. It has many potential negative impacts, including: loss of livelihood, injury and death, persecution of species, and loss of habitat. There are numerous ways to mitigate and prevent human-wildlife conflict. The first step to minimizing it is understanding the root causes and factors that contribute to it.
Climate change may exacerbate human-wildlife conflict in several ways. One example is the shifting of marine predators’ ranges due to warmer sea temperatures. Another is the growth of human population in the vicinity of wildlife habitats.
Moreover, climate change could exacerbate conflict by increasing the likelihood of people and wildlife competing for resources. Specifically, this might be the case with bears, who are forced to expand their search for prey. They are also more likely to venture closer to human settlements.
Human-wildlife conflict is a global issue that should be addressed by policymakers. For instance, the IUCN World Conservation Congress Resolution on human-wildlife conflict highlights the need to improve the welfare of both people and animals, while at the same time protecting natural areas. In addition, it calls for the inclusion of human-wildlife conflict into Sustainable Development Goals (SDGs) implementation plans.
Some of the factors that can lead to human-wildlife conflict include: the expansion of human populations into the area of wildlife habitats; the spread of diseases in wild animals; and the introduction of new species into a given ecosystem. As a result, wildlife is forced to share limited resources, thereby increasing the risk of extinction.
Climate change is a huge contributor to human-wildlife conflict. It increases the risk of extreme weather events. This includes droughts, marine heatwaves, and disease outbreaks. Additionally, it has a direct effect on vegetation in forests and vegetation in agricultural fields.
While the impact of climate change on wildlife is still being investigated, researchers have identified a few potential sources of human-wildlife conflict. These include: polar bears, who are forced to expand their hunting and feeding habits, and flying foxes, who need to be hosed down to keep them cool.
Regardless of the factors that cause human-wildlife conflict, it can be a very complex process. However, researchers have discovered several techniques for detecting and minimizing it.
Predicting whether a population will go extinct
Predicting whether a population will go extinct due to climate change depends on the life history traits of the species and its environment. Life history traits include species’ longevity, age, reproductive capacity and their ability to survive extreme weather events. However, life-history traits can only be documented in a few species, and can only be experimentally confirmed.
Recent studies have shown that climate-related extinctions have occurred in recent years. Researchers from the University of Arizona have combined data on extinctions and climate to estimate the likelihood that nearly 8% of current species will go extinct by the year 2070.
Species can respond to changing conditions in three ways: by moving to cooler habitats, persisting in the existing habitat, or becoming extinct. While some species will survive the changes, most will not be able to escape quickly enough. These results indicate that global biodiversity will suffer from climate change.
Climate-related extinctions are occurring at different rates at different sites. The study examined long-term population records of 157 mammal species. A key variable was maximum annual temperatures. Increasing temperatures at a site were associated with local extinctions. They also found that shorter living mammals were more susceptible to changes in weather.
Despite the fact that climate-related extinctions are occurring, researchers are still unsure about the best way to predict which species will go extinct. There are many technical and data-acquisition challenges that prevent current approaches from reaching their full potential. Fortunately, new technologies are making it easier to integrate genetic information into ecological projections. This could revolutionize the way we quantify species vulnerability to climate change.
One approach is to combine genomic data and traditional population genomic techniques to develop hybrid SDMs. Genomics-based SDMs subdivide species’ distribution into genetic clusters associated with climatic conditions. By integrating these approaches with other models, such as eco-evolutionary models, more realistic predictions are possible.
Another approach is to use time-for-time analyses. In this approach, data is gathered from natural populations. Such analysis is less relevant for assessing broad-scale biodiversity responses to climate change. It is only useful for species that have been surveyed over a long period of time.
