Prey type and foraging ecology of Sanderlings Calidris alba in different climate zones: are tropical areas more favourable than temperate sites? [PDF]

open access: yesPeerJ, 2015
Sanderlings (Calidris alba) are long-distance migratory shorebirds with a non-breeding range that spans temperate and tropical coastal habitats. Breeding in the High Arctic combined with non-breeding seasons in the tropics necessitate long migrations ...

Archigregarines of the English Channel revisited: New molecular data on Selenidium species including early described and new species and the uncertainties of phylogenetic relationships. [PDF]

open access: yesPLoS ONE, 2017
Gregarines represent an important transition step from free-living predatory (colpodellids s.l.) and/or photosynthetic (Chromera and Vitrella) apicomplexan lineages to the most important pathogens, obligate intracellular parasites of humans and domestic ...

Benthic macrofauna of sandy intertidal zone at Santos estuarine system, São Paulo, Brazil

open access: yesBrazilian Journal of Oceanography, 1991
Species composition, faunal density, species diversity and zonation patterns of benthic macrofauna, as well as its relation to sediment characteristics were examined and compared in three sandy beaches on the polyhaline area at Santos estuarine system in

Macroinfauna of Six Beaches near Guaratuba Bay, Southern Brazil

open access: yesBrazilian Archives of Biology and Technology, 2001
Benthic macroinfauna of six beaches near to Guaratuba Bay, Paraná, Brazil were studied in summer and winter of 1994. Sampling stations were distributed along a transect, from upper of the drift line to depths of nearly 3 m behind the first break of the ...

Effects of waste waters on benthic macrofauna of sandy beaches in Todos Santos Bay

open access: yesCiencias Marinas, 1992
The seasonal study of the benthic macrofauna in Todos Santos Bay shows the effects of waste waters on the benthic communities of the intertidal zone. The analysis of the data separates the fauna into two main associations: one made up of the populations

Spatial distribution of annelids in the intertidal zone in Sao Sebastiao Channel, Brazil

open access: yesScientia Marina, 2001
We studied the spatial distribution of annelids in the intertidal zone of two beaches (Engenho d´Água and São Francisco) in São Sebastião Channel, southeastern Brazil, from August 1995 through July 1996. This region is commonly affected by oil spills and

Variability of macrofauna distribution along a dissipative log-spiral sandy beach in Rio de Janeiro, Southeastern Brazil

open access: yesScientia Marina, 2017
Log-spiral beaches display defined physical gradients alongshore. However, the majority of studies focus on the variability of a single population of macrofauna species.

Approximate Bayesian computation for Markovian binary trees in phylogenetics [PDF]

open access: yesarXiv, 2023
Phylogenetic trees describe the relationships between species in the evolutionary process, and provide information about the rates of diversification. To understand the mechanisms behind macroevolution, we consider a class of multitype branching processes called Markovian binary trees (MBTs).

Potential long-term disturbance associated with beach nourishment - insights and observations from Pea Island National Wildlife Refuge, Outer Banks, North Carolina

open access: yesHeliyon, 2023
The longer-term ecosystem impacts associated with a beach nourishment project conducted in 2014 were studied on an ocean beach on the Pea Island National Wildlife Refuge on North Carolina's Outer Banks.
