“After seeing what the physique traits of the fish have been, we are able to predict how local weather change will have an effect on the sizes of those species in the event that they proceed to face a rise in temperature within the years 2050-2100,” she says.

Moraga has additionally studied a variant of the 5S gene in rays present in freshwater and marine environments, in addition to figuring out the evolution of physique measurement in sharks and rays, utilizing phylogenetic-ecological info.

“We will decide which have been the optimum sizes in sure geological instances such because the sizes reached by extinct species such because the (large shark) Megalodon,” she says.

Childhood Ardour for Nature

Moraga grew up in Cali, Colombia, which is a land-locked metropolis, a number of hours drive kind Colombia’s Pacific coast and really early on she had an affinity for nature and the pure sciences.

One other Colombian researcher who’s trying into the previous for clues to easy methods to confront future challenges is Catalina Suarez.
