RESOURCE SUBSIDIES ACROSS AQUATIC-TERRESTRIAL BOUNDARIES OF TEMPORARY PONDS
Aquatic habitats are closely linked to surrounding terrestrial habitats via reciprocal subsidies. Much of the research on these subsidies has been focused on streams and lakes, while subsidies across aquatic-terrestrial boundaries of seasonally inundated temporary ponds have received little attention. To address the lack of information regarding these cross-habitat subsidies, we quantified: 1) leaf litter inputs, 2) amphibian egg inputs, 3) terrestrial insect inputs, 4) amphibian metamorph emergence, and 5) aquatic insect emergence for eight temporary ponds. Leaf litter input represented the largest subsidy in this study (93%), followed by terrestrial insect inputs (5%), which represented substantial high-quality subsidies to ponds, and are generally unaccounted for in similar studies. Aquatic insect emergence (0.3%) was generally lower than amphibian metamorph emergence (0.8%). Amphibian egg inputs to ponds represented only 0.2% of total subsidies. Although larger ponds produced greater total fluxes to terrestrial habitats, smaller ponds were often more productive per unit area. Therefore, a mosaic of small ponds may produce greater or equivalent subsidies and may be more important to terrestrial food webs than single large ponds.
