Professor of Biology. Carlos Botero developed a new model to investigate the effect of extreme weather conditions on living things and to follow the evolutionary adaptation of living things that have not been subjected to such events in history.
Extreme weather events are becoming more frequent, more severe and more common as a result of climate change. Hurricane Dorian is the last example of this scary course. A new study at the University of Washington shows what the consequences of these events will be.
According to studies, animals and plants facing unique changes go through difficult processes. The professor who wants to draw attention to this point. Carlos Botero and his student Thomas Haaland developed a new model. This model helps to predict changes that could lead to the extinction of a particular species.
Talking about the content of the study. “It is difficult to predict how organisms will respond to changes in extreme events because these phenomena are by definition very rare,” Botero said. In this context, Botero says that reviewing the natural history of organisms, past climate regimes and changes in the past will help to better understand the event.
Unexpected vulnerabilities have emerged:
Botero worked with Haaland, a former student at the University of Zurich in Switzerland, to develop an evolutionary model of how populations respond to rare environmental endpoints. The professor thinks that it is difficult for these rare events to affect evolution. Particular attention was drawn to the research as follows:
Species that reproduce only once in their lifetime tend to develop conservative behaviors or morphologies as if they always hoped they would begin an environmental extreme event. In contrast, species where a single individual can multiply more than once and in different contexts (eg a bird nesting on different trees in one season); evolution and environmental extremes.
The main conception of this new model is that species of the “conservative” category can easily adapt to the more common endpoints, but if these endpoints become denser, it is difficult to make adjustments. Ero We see that simple changes in the layout and density of environmental endpoints can be fatal even for populations that have experienced similar events in the past, Bot Botero said. This model helps us better understand when and where we will have problems.
The model can be applied to many peripheral end conditions:
Haaland and Botero say that this simple model can be applied to all kinds of environmental extremes, such as flood, wildfire, heatwave, drought, cold weather and hurricane. Take extreme heat as an example. When there is hot air above normal, this model can be used to predict what will happen to animal or plant species when heat waves last longer or when typical heat waves affect larger areas. Botero’s explanations are as follows:
Geller The regions where heatwaves are rare to contain species that do not exhibit remarkable adaptations to extreme heat. Conversely, areas, where historically hot waves are widespread, can be expected to accommodate species that have already adapted for extreme heat. In this case, our model shows that typical inhabitants in areas where heat waves are rare will be more vulnerable to extreme temperatures. ”
Professor This model, developed by Botero and his student, shows that extreme weather conditions can lead to “fatal” consequences for species that have never experienced such troubles in the past. Now, the professor wants to improve his model and expand his research.
