THE SENSITIVITY OF ANTS ON SOIL AND AIR TEMPERATURE AS BIOINDICATORS OF CLIMATE CHANGE IN SMALL ISLANDS OF INDONESIAFransina Latumahina and Gun Mardiatmoko
The international community is worried about the increasing number of disasters caused by climate change. The main effort is to carry out mitigation and adaptation programs. In this regard, one of the studies that need to be done is to see ants as bioindicators of climate change. Sampling of ants is carried out by systematic sampling with a path length of 250 m and a width of 20 m as many as 10 lines. Line distance of 30 m. Three methods of taking ants were carried out, namely: (1) Hand Collecting (2) Pitfall trap and (3) Bait trap and preserved in 70% alcohol. The type of ant that has a strong correlation with air temperature and / or soil temperature will be more sensitive to climate change than the type with low correlation. Thus only certain types of ants can be used as bioindicators of climate change. From the results of the inventory of ants, 32 species of ants were obtained as many as 3,110 tails. Of the 32 types of ants, 5 of the most common species were found and the 5 least species were found. The types of ants that are included have a high correlation with soil temperature and air temperature, namely: Cardiocondyla nuda, Myrmicaria brunnea subcarinata, Polyrhachis bellicosa, Myrmoteras binghami and Crematogaster difformis. This type of ant is most rarely found at the study site. Ants that are less correlated with soil temperature and air temperature are: Polyrhachis abdominal, Hypoponera bugnioni, Leptogenys diminuta, Odonthoponera tranversa infuscata and Oecophylla smaragdina subnitide. This type of ant is most easily found in the study location.
