Keeping safe and fed: large heterospecific shorebird flocks to decrease intraspecific competition
(Wiley-Blackwell, 2020-01-01)
Shorebirds join cohesive flocks for safety. The joining of individuals of several species in large heterospecific flocks can optimise individual vigilance and foraging. However, a large number of conspecific individuals ...
BIRD FORAGING IN ANACARDIUM PATCHES IN CENTRAL BRAZILIAN FIRE BREAKS: RELATIONSHIP BETWEEN FLOCK SIZE AND PATCH SIZE
(NEOTROPICAL ORNITHOLOGICAL SOC, USGS PATUXENT WILDLIFE RESEARCH CTR, 2009)
Fire management ran increase the biomass of some plant species at fire breaks in reserves of the Cerrado. For example, numerous and large patches of monkey-nuts (Anacardium humile, Anacardiaceae) provide abundant food ...
Vigilance towards raptors by nuclear species in bird mixed flocks in a Brazilian savannah
(Swets Zeitlinger Publishers, 2002-12-01)
A nuclear or leader species is the one around which foraging activity is organized. In the campo-cerrado (Brazilian savannah) up to four bird species (Saltator atricollis, Cypsnagra hirundinacea, Mimus saturninus, and ...

Silent Flocks: Constraints on Signal Propagation Across Biological Groups
(American Physical Society, 2015-05)
Experiments find coherent information transfer through biological groups on length and time scales distinctly below those on which asymptotically correct hydrodynamic theories apply. We present here a new continuum theory ...
Experimental forest fragmentation alters Amazonian mixed-species flocks
(Elsevier B.V., 2020-02-01)
Habitat fragmentation has been associated with myriad negative effects for forest-dependent birds in the Neotropics. However, the vast majority of negative effects have been inferred from comparisons of pre-existing fragments ...
Decay of interspecific avian flock networks along a disturbance gradient in Amazonia
(Royal Soc, 2014-02-07)
Our understanding of how anthropogenic habitat change shapes species interactions is in its infancy. This is in large part because analytical approaches such as network theory have only recently been applied to characterize ...
