Primary Research Paper


Trophic interaction between contiguous habitats is an understudied area despite their ecological importance. We tested four hypotheses related to the visit of foraging birds in temporary ponds inhabited by fish: the local characteristics of ponds influence the (1) abundance and (2) composition of foraging birds; (3) the number of foraging bird visits increases in higher fish abundance; and (4) pond characteristics lead to a non-random spatial structure of fish assemblage. We studied 18 temporary ponds in the floodplain area of Pantanal (center-west Brazil), where we measured environmental variables (pond size, depth, macrophyte coverage, and forest canopy coverage), recorded the number of foraging birds and sampled fish. Foraging birds’ abundance and composition were mainly influenced by forest canopy coverage and pond size, corroborating our first and second hypotheses. The hypotheses 3 and 4 were rejected. Fish abundance was not correlated with higher number of visits of foraging birds and fish distribution was random. Local environmental variables did not affect significantly fish richness and composition. Our results suggest that the abundance of foraging birds and fish presence are determined by different assembly processes (deterministic vs. random), which may limit ponds selection by birds due to the uncertainty in fish distribution and ephemeral nature of temporary ponds.

This study was designed and developed during the Pantanal Ecology course (Ecologia do Pantanal—ECOPAN) of 2013. Thus, we would like to thank all organizers, professors, sponsors (UFMS, MMX, Fundect, Capes, CNPq, Instituto Homem Pantaneiro, Embrapa Pantanal, PPG Ecologia e Conservação), and participants of the ECOPAN 2013 for field logistics, suggestions, and team play. We also thank Elaine Corrêa for all help in the field work and Paulo Henrique Araujo and Francisco Severo Neto for bird and fish identification. The first author would like to thank CAPES/UFRGS for the master’s degree scholarship, and CNPq/UEM and CAPES/Texas A&M for PhD scholarships. We also thank the editor and the anonymous reviewers for improving the manuscript with comments and suggestions.
