Spatial and temporal variability of sandy intertidal macrobenthic communities and their relationship with environmental factors in a tropical island

Patterns of spatial and temporal distribution of the macrobenthic fauna on an estuarine macrotidal sandy beach on the Amazon coast (Brazil)

“…A similar pattern was also found in areas influenced by monsoons, where large changes in the benthic fauna were related to the high rainfall during monsoon months (Ansell et al, 1972;Equbal et al, 2018;Pandey & Thiruchitrambalam, 2019).…”

“…High pluviosity sharply reduces salinity, leading to the restriction or exclusion of species that are exclusively marine or poorly adapted to low salinity (Kinne, 1971). A similar pattern was also found in areas influenced by monsoons, where large changes in the benthic fauna were related to the high rainfall during monsoon months (Ansell et al., 1972; Equbal et al., 2018; Pandey & Thiruchitrambalam, 2019).…”

Spatial variation in macrobenthic assemblages and their relationship with environmental factors in the upstream and midstream regions of the Heihe River Basin, China

“…Compared with the upper reaches, the middle reaches were greatly affected by anthropogenic activities, which led to complex and changeable river habitat conditions; in addition, the nutrients were abundant and the stability and heterogeneity of the riverbed were high. Previous studies have shown that greater riverbed sediment stability and habitat heterogeneity are associated with high biodiversity (Shumway et al 2007;Pandey and Thiruchitrambalam 2019).…”

Biomonitoring of the Application of Monoculture and Integrated Multi-Trophic Aquaculture (IMTA) Using Macrobenthic Structures at Tembelas Island, Kepulauan Riau Province, Indonesia

“…Environmental variability is believed to be the key to changes in microbenthic structure expressed by variation in index values. Depending on the location, the main environmental factors affecting the distribution and structure of macrobenthic animals reported by most authors, such as food availability, particularly organic matter, salinity and sediment characteristics, especially mud or clay content, and hydrodynamic water ecosystem, explained a significant part of macrobenthic spatial patterns [1,10,14,15,18].…”

“…However, some studies have shown the importance of physical abiotic factors as the main drivers of the spatial patterns of macrobenthic species distribution, i.e., temperature and salinity gradients of water [13], the availability of food, dissolved organic particles, salinity, and sediment grain sizes [14]. Spatially, they are mainly influenced by sediment characteristics, such as organic matter and grain size [15]. This study covered three different sampling locations, namely where the IMTA farming method was applied (IMTA Site), a reference site situated roughly 1 km from the IMTA site (Reference Site), and a monoculture site situated roughly 3 km from the IMTA site (Monoculture Site) ( Figure 1).…”
