Anthropogenic disturbance, especially human induced climate change, are the main causes of the rapid decline of biodiversity observed worldwide over the last years. Arthropods are especially responsive to climatic changes due to their ectothermic metabolism and short generation times. Their historic and contemporary use as indicators of environmental health could be a useful technique in monitoring and anticipating the impacts of future climatic change on ecosystems. Accordingly, to predict these impacts, it is important to understand how the abiotic environment shapes arthropod communities. In collaboration with the Ministère des Forêts, de la Faune et des Parcs (MFFP) and Ministère de l'Environnement et de la Lutte contre les changements climatiques (MELCC), in conjunction with sampling in 2018-2019, we used data from the provincial biodiversity monitoring survey to answer the following questions : (1) How do arthropod species assemblages vary along latitudinal and climatic gradients? (2) What species from these assemblages would be suitable indicators of ecosystem changes?
