“…, Oliver Zielinski a geochemical cycles, significant disciplinary and interdisciplinary gaps in understanding beach ecosystem functioning remain because most studies were uni-disciplinary and focused either on ecology, physical beach environment, management, or biology (Dugan et al, 2010;Nel et al, 2014). Therefore, we conducted a study that combines the disciplines sedimentology, hydrology, biogeochemistry, microbiology, and ecology.…”

The drivers of biogeochemistry in beach ecosystems: A cross-shore transect from the dunes to the low-water line

This study addresses key processes in high-energy beach systems using an interdisciplinary approach. We assess spatial variations in subsurface pore water residence times, salinity, organic matter (OM) availability, and redox conditions and their effects on nutrient cycles as well as on microbial community patterns and microphytobenthos growth. At the study site on Spiekeroog Island, southern North Sea, beach hydrology is characterized by the classical zonation with an upper saline plume (USP), a saltwater wedge, and a freshwater discharge tube in between. Sediment and pore water samples were taken along a cross-shore transect from the dunes to the low-water line reaching sediment depths down to 5 m below sediment surface. Spatial variations in pore water residence time, salinity, and organic matter availability lead to steep redox and nutrient gradients. Vertical and horizontal differences in the microbial community indicate the influence of these gradients and salinity on the community structure. shoreline. We propose that this nutrient efflux triggers growth of microphytobenthos on sediment surfaces of the discharge zone. A first comparison of nutrient discharge rates of the beach site with a nearby sandy backbarrier tidal flat margin indicates that the beach system might be of less importance in supplying recycled nutrients to nearshore waters than the backbarrier tidal flat area.

Gonzalez and Vaske Junior: Feeding of Atherinella blackburni in Brazil 346Feeding ecology of the beach silverside Atherinella blackburni (Atherinopsidae) in a tropical sandy beach, Southeastern Brazil A ecologia alimentar do peixe-rei (Atherinella blackburni) na zona de arrebentação de uma praia arenosa tropical, localizada no sudeste do Brasil, foi acessada a partir da análise do conteúdo alimentar de 198 peixes. Fatores como o tamanho, a estação do ano e o período do dia foram analisados para compreender como estes influenciam a dieta da espécie. Os resultados mostram que A. blackburni é um peixe nerítico costeiro com amplo nicho alimentar. As presas mais recorrentes foram os crustáceos zooplanctônicos, insetos e moluscos bentônicos, sendo os crustáceos da subclasse Copepoda o item dominante na dieta em ocorrência e abundância. A. blackburni aparenta possuir uma leve mudança ontogênica em sua dieta, variando de moluscos bentônicos para crustáceos e em seguida para insetos ao longo do seu ciclo de vida. A atividade diária também demonstrou ser um fator importante para a ecologia alimentar de A. blackburni. O predomínio de peixes pequenos durante o período da manhã, juntamente com as principais presas para esta classe de tamanho, sugere que indivíduos pequenos utilizem as áreas mais rasas para alimentação durante o período da manhã e, durante a noite, movem-se para águas mais profundas em busca de proteção contra predadores. A. blackburni appears to have a slight ontogenetic shift in its diet, changing from benthic molluscs to crustaceans and insects along its life cycle. The diel activity also reveals to be an important factor to the A. blackburni feeding ecology. The predominant occurrence of small fish during the morning, along with the main preys for this size class, suggests that small individuals use shallower waters as feeding grounds during the morning and, during the night, they move to deeper waters for protection against predators.

“…Although our understanding of the ecology of sandy shores has greatly advanced since the 1980's (Defeo and McLachlan, 2005;McLachlan and Brown, 2006;Nel et al, 2014), this habitat is still overlooked in studies of the ecological impacts of global change, e.g. increase in seawater temperature .…”
