Species of the páramo affected by climate change

An analysis of the moorland ecosystem in Costa Rica revealed drastic changes in the local flora due to the effect of climate change.

The main results show that a large number of plants have decreased due to the scarcity of pollination and, therefore, there is less reproduction of flora species.

Animals are also affected, as the chances of finding food are diminished.

Paramo ecosystems are those found in the peaks of hills and highlands, generally have a humid climate.

The Costa Rican páramo has more than 70% of the plants with flowers registered in these ecosystems in Latin America.

Researchers from the University of Costa Rica (UCR), the Universidad Nacional (UNA), the Tecnológico de Costa Rica (TEC) and the Estatal a Distancia (UNED) participated in the study.

The research was carried out in Cerro Buena Vista, Cerros Sákira and Cerro Las Vueltas Biological Reserve.

Mobilization

Not only is there a decline in plant species; the increase in the Earth’s temperature also forces various species of animals and flora to migrate to higher ground such as moors.

This has caused pollinator species such as bees and hummingbirds to affect their habitats, food and ecosystem dynamics.

According to María Maglianesi, biologist at the UNED, “a high level of asynchrony was found in plant-pollinator interactions,” which averaged 26 days.

In other words, pollinators are more advanced than the plants they visit, which affects the food availability of some animals.
