Moreover, total respiration of the guild in relation to season was roughly estimated. Most data were from one site in northern Zealand, Denmark. The energy requirements of this coprophagous guild varied widely through the season. Even at the time of maximum activity, the beetles assimilated only about 0.2% of the energy in a dung pat; hence there is no evidence of competition for food at normal population densities. Neither did other results indicate within-guild competition, past or present. Features like (1) the contagious distribution of beetles on evenly spaced, identical pats, (2) the positive association between species, and (3) habitat specializations within pats may have evolved as adaptations facilitating intraspecific contacts in populations which are often sparse in relation to chances of mating. /// ÃÂ ÃÂ°Ã‘ÂÃÂ¿Ã‘â‚¬ÃÂµÃÂ´ÃÂµÃÂ»ÃÂµÃÂ½ÃÂ¸ÃÂµ Ã‘â‚¬ÃÂµÃ‘ÂÃ‘Æ’Ã‘â‚¬Ã‘ÂÃÂ¾ÃÂ² ÃÂ² ÃÂ³Ã‘â‚¬Ã‘Æ’ÃÂ¿ÃÂ¿ÃÂµ ÃÂ¸ÃÂ· 13 ÃÂ²ÃÂ¸ÃÂ´ÃÂ¾ÃÂ² Aphodius (ÃÂ¸ÃÂ¼ÃÂ°ÃÂ³ÃÂ¾) ÃÂ¸ÃÂ· Ã‘ÂÃÂºÃ‘ÂÃÂºÃ‘â‚¬ÃÂµÃÂ¼ÃÂµÃÂ½Ã‘â€šÃÂ¾ÃÂ² ÃÂºÃ‘â‚¬Ã‘Æ’ÃÂ¿ÃÂ½ÃÂ¾ÃÂ³ÃÂ¾ Ã‘â‚¬ÃÂ¾ÃÂ³ÃÂ°Ã‘â€šÃÂ¾ÃÂ³ÃÂ¾ Ã‘ÂÃÂºÃÂ¾Ã‘â€šÃÂ° ÃÂ¸Ã‘ÂÃ‘ÂÃÂ»ÃÂµÃÂ´ÃÂ¾ÃÂ²ÃÂ°ÃÂ»ÃÂ¸ ÃÂ² ÃÂ´ÃÂ²Ã‘Æ’Ã‘â€¦ ÃÂ²Ã‘â‚¬ÃÂµÃÂ¼ÃÂµÃÂ½ÃÂ½Ã‘â€¹Ã‘â€¦ ÃÂ¸ÃÂ·ÃÂ¼ÃÂµÃ‘â‚¬ÃÂµÃÂ½ÃÂ¸Ã‘ÂÃ‘â€¦ - ÃÂ² ÃÂ¾Ã‘â€šÃÂ½ÃÂ¾Ã‘Ë†ÃÂµÃÂ½ÃÂ¸ÃÂ¸ ÃÂº Ã‘ÂÃÂµÃÂ·ÃÂ¾ÃÂ½Ã‘Æ’ ÃÂ¸ ÃÂ²ÃÂ¾ÃÂ·Ã‘â‚¬ÃÂ°Ã‘ÂÃ‘â€šÃ‘Æ’ Ã‘ÂÃÂºÃ‘ÂÃÂºÃ‘â‚¬ÃÂµÃÂ¼ÃÂµÃÂ½Ã‘â€šÃÂ¾ÃÂ², ÃÂ¸ ÃÂ² ÃÂ´ÃÂ²Ã‘Æ’Ã‘â€¦ ÃÂ¿Ã‘â‚¬ÃÂ¾Ã‘ÂÃ‘â€šÃ‘â‚¬ÃÂ°ÃÂ½Ã‘ÂÃ‘â€šÃÂ²ÃÂµÃÂ½ÃÂ½Ã‘â€¹Ã‘â€¦ ÃÂ¸ÃÂ·ÃÂ¼ÃÂµÃ‘â‚¬ÃÂµÃÂ½ÃÂ¸Ã‘ÂÃ‘â€¦ - ÃÂ² ÃÂ¾Ã‘â€šÃÂ½ÃÂ¾Ã‘Ë†ÃÂµÃÂ½ÃÂ¸ÃÂ¸ ÃÂº Ã‘â‚¬ÃÂ°Ã‘ÂÃÂ¿Ã‘â‚¬ÃÂµÃÂ´ÃÂµÃÂ»ÃÂµÃÂ½ÃÂ¸Ã‘Å½ ÃÂ¶Ã‘Æ’ÃÂºÃÂ¾ÃÂ² ÃÂ² Ã‘â‚¬ÃÂ°ÃÂ·ÃÂ½Ã‘â€¹Ã‘â€¦ ÃÂºÃ‘Æ’Ã‘â€¡ÃÂ°Ã‘â€¦ Ã‘ÂÃÂºÃ‘ÂÃÂºÃ‘â‚¬ÃÂµÃÂ¼ÃÂµÃÂ½Ã‘â€šÃÂ¾ÃÂ² ÃÂ¸ ÃÂ¸Ã‘â€¦ ÃÂ¼ÃÂ¸ÃÂºÃ‘â‚¬ÃÂ¾Ã‘â‚¬ÃÂ°Ã‘ÂÃÂ¿Ã‘â‚¬ÃÂµÃÂ´ÃÂµÃÂ»ÃÂµÃÂ½ÃÂ¸Ã‘Å½ ÃÂ² ÃÂ¿Ã‘â‚¬ÃÂµÃÂ´ÃÂµÃÂ»ÃÂ°Ã‘â€¦ ÃÂ¾ÃÂ´ÃÂ½ÃÂ¾ÃÂ¹ ÃÂºÃ‘Æ’Ã‘â€¡ÃÂ¸.
