BODY SIZE MEDIATED COEXISTENCE IN SWANS

Body Size Mediated Coexistence in Swans

Differences in body sizes may create a trade-off between foraging Accessories efficiency (foraging gains/costs) and access to resources.Such a trade-off provides a potential mechanism for ecologically similar species to coexist on one resource.We explored this hypothesis for tundra (Cygnus columbianus) and trumpeter swans (Cygnus buccinator), a fed

Examination of Sarcocystis spp. of giant snakes from Australia and Southeast Asia confirms presence of a known pathogen - Sarcocystis nesbitti.

We examined Sarcocystis spp.in giant snakes from the Indo-Australian Archipelago and Australia using a combination of morphological (size of sporocyst) and molecular analyses.We amplified by PCR nuclear 18S rDNA from single sporocysts in order to detect mixed infections and unequivocally assign the Collections retrieved sequences to the correspondi
