Inilah Semut Yang Lebih Suka Garam Ketimbang Gula

2008/11/04
Coba perhatikan perilaku semut di sekitar rumah Anda. Pisang goreng atau kerupuk di atas meja makan yang notebene tidak manis apakah tetap dikerumuni seperti halnya sejumput gula atau sirup yang tumpah. Kenyataannya sebagian koloni semut bahkan lebih menyukai garam daripada gula. Setidaknya perilaku ini terlihat pada semut-semut yang tinggal di pedalaman yang jauh dari laut. "Ketertarikan terhadap garam meningkat seiring jarak dari laut," ujar Profesor Robert Dudley, salah satu peneliti dari Universitas California Berkeley, AS. Kesimpulan tersebut diambil setelah Dudley dan koleganya dari Universitas Arkansas Little Rock (UALR) dan Universitas Oklahoma membandingkan sejumlah populasi semut di Amerika. Mereka mempelajari perilaku semut dari Amerika Tengah, Selatan, dan Utara yang hidup di lokasi berbeda-beda. Semut yang hidup di habitat berjarak 96 kilometer dari garis pantai ternyata lebih suka larutan garam satu persen daripada larutan gula 10 persen. Kecenderungan ini tampak sekali pada semut pemakan daun daripada semut pamakan daging, seperti semut merah. Semut pemakan daun mungkin membutuhkan asupan garam tambahan lebih banyak karena tidak memperoleh sebanyak semut pemakan daging. Alasan ini sama halnya dengan seekor bison, kijang, atau badak yang suka menjilat tanah untuk menambah asupan garam. Sementara hewan pemakan daging seperti singa gunung dan srigala tidak melakukannya karena sudah cukup mendapatkan garam dari mangsanya. (kompas)
