TITLE:

THE INFLUENCE OF CLIMATE CHANGE AND LAND USE ON
DISTRIBUTION OF EPHEMEROPTERA SPECIES (INSECTA)
THREATENED WITH EXTINCTION IN BRAZIL

KEY WORDS:

Niche Modeling, Neotropical, Atlantic Forest, Conservation, Suitability

PAGES: 71
BIG AREA: Ciências Biológicas
AREA: Ecologia
SUMMARY:

Climate change, primarily driven by deforestation, has significant impacts on

global biodiversity, affecting distribution and increasing species extinction. Strong

evidence suggests that changes in the abundance, distribution, and diversity of aquatic

insects are consistent with the widespread effects of land use and climate change.

Understanding these combined effects is essential for predicting future patterns in

species distribution and managing biodiversity conservation strategies. This study

aims to identify, in different scenarios, the potential geographic distribution of

endangered Ephemeroptera species in Brazil. The R 4.1.2 environment with the

ENMTML package (ANDRADE et al., 2020) was used, with the Bioclim, Domain, and

RandomForest algorithms for modeling, with 10 replicas for each species. The metrics

used were Area Under the Curve (AUC), True Skill Statistic (TSS), Jaccard, Sørensen,

and Fpb. The open-source software QGIS version 3.16.2 was used to produce the

maps. Occurrence points of six endangered Ephemeroptera species and a set of

environmental variables represented by seven bioclimatic variables plus two terrain

variables were used. The results corroborate that all species are vulnerable or at risk

of future extinction, with fragmented areas with little suitability for species survival.
