A survey of hoolock gibbon  populations was also carried out at 14 sites where  encounter rate, group size and age-sex ratios were  compared between forest size classes. Habitat  variables were influenced more by disturbance level  than fragment size. Disturbed fragments had lower  canopy continuity, food tree diversity, and  important food sources like lianas and climbers.  Home range size was not correlated to the size of  the forest. Gibbons in the two smallest fragments  had almost no fruit in their diet at the end of the  dry season. Gibbons in the disturbed fragments spent  the least time in social interactions and called  less frequently during times of fruit shortage  indicating that they make trade-offs between  conserving energy and investment into group bonding  or territorial defense. Encounter rates of gibbon  groups were lower, and group sizes smaller, in the  fragments than in the large forest.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838378978\"\u003e\u003ch3\u003eHow gibbon populations, home ranges, diet, calling and social behaviour are affected by forest  fragmentation\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838378978","offer_id":39499042979933,"sku":"9783838378978","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/a7ab2522-7c50-47a6-a728-08acbb8432fc.jpg?v=1758779576","url":"https:\/\/shop.autorenwelt.de\/products\/impact-of-forest-fragmentation-on-the-hoolock-gibbon-in-assam-india-von-kashmira-kakati","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
