“…It is known that a range of environmental factors affect the trait diversity of the macrofauna (Park et al, 2008). For example, the functional groups of tube-dwellers/burrowers and deposit feeders are often abundant in silty-sand habitats, whereas sandy sediments often are characterized by motile surface crawlers and carnivores/scavengers (Kun et al, 2019).…”

Macrofauna play a key role in the functioning of mangrove ecosystems. Nevertheless, our understanding of the diversity and functional structure of macrofaunal communities across different habitats in the mangrove forests of the Persian Gulf is limited. In this study, we investigated species diversity and biological trait patterns of macrofauna in different mangrove-associated habitats, i.e., encompassing actual mangrove forests, and adjacent Beaches and Creeks, which exhibit different levels of habitat heterogeneity. Samples were collected from the different habitats in five different locations, over four seasons. A total of 122 macrofauna taxa were identified. The diversity of species was higher in summer than in winter. In the Beach habitats, species diversity showed an increasing trend from land toward the mangrove, whereas in Creek habitats diversity decreased from the Creek toward the mangrove. Multivariate community analysis showed differences in the distribution of abundant species and biological traits across all habitats. Deposit-feeding, crawlers, medium-size, and free-living were the dominant trait modalities in all habitats. The similarities within habitats over the four seasons had the same specific pattern of species and biological trait abundance in the Beach and the Creek, increasing from the non-covered habitat into the mangrove trees. Although many species shared similar traits, the abundance-driven differences in trait expression between habitats showed the importance of habitat filtering. The results of this study will be useful in the conservation of mangrove forests and they give a deeper understanding of the ecological patterns and functions of benthic macrofaunal communities in the Persian Gulf.

“…This finding is consistent with a previous report from Chen and Ma (2017), who found that phytophages were the dominant FFG in a mangrove wetland (located in same area as the wetland in the current study) whether or not the area had been invaded by Spartina alterniflora.

Along the north coast of Spain, for example, the occurrence of different macroinvertebrate FFGs was best explained by chlorophyll-a concentration, wave exposure, sea surface temperature, and beach slope (Rodil et al 2014).…”

Understanding the relationships between mangrove forest succession and the functional diversity of mangrove fauna could facilitate the restoration of mangrove ecosystems, which have been severely damaged in recent decades. The current report describes changes in macrobenthic functional diversity in a mangrove chronosequence that included a primary community (unvegetated shoal), an early community (Avicennia marina), a middle community (Aegiceras corniculatum), and a late community (Bruguiera gymnorrhiza + Rhizophora stylosa) in Zhanjiang, China. Phytophages were the dominant macrobenthic functional feeding group regardless of mangrove succession stage, sampling season, or macrobenthic faunal parameter (species richness, abundance, and biomass). As mangrove succession progressed, the proportions of macrobenthic species richness, abundance, or biomass represented by omnivores significantly increased (except for biomass and in the late stage; ranged from 0.065 to 0.230 and 0.033 to 0.368, respectively in wet season, and 0.000 to 0.192 and 0.000 to 0.396, respectively in dry season), while the proportions significantly decreased for detritivores during the dry season (ranged from 0.156 to 0.056, 0.107 to 0.019, and 0.066 to 0.005, respectively). Non‐metric multi‐dimensional scaling and PERMANOVA also indicated that the structure of macrobenthic faunal functional feeding groups was significantly affected by mangrove succession. Further analyses indicated that the changes in the relative dominance among macrobenthic faunal functional feeding groups during mangrove succession were mainly associated with changes in plant density, coverage/canopy density, and total nitrogen content of sediment, i.e., they were mostly associated with changes in food sources. The results increase our understanding of the relationship between benthic functional diversity and mangrove succession and could help guide mangrove restoration in China and around the world.

“…However, some scientists prefer to use benthic macroinvertebrates in bioassessment (Reece & Richardson, 2000). Benthic macroinvertebrates continuously respond to short-and long-term disturbances of their habitat (Park et al, 2008), such as flooding, siltation brought about by deforestation (Stanford, 2006), agriculture effluents, and urban pollution (Compin & Céréghino, 2007). In addition, their sedentary foraging, short life cycles, and preference for habitats around toxic sediments make benthic macroinvertebrates ideal candidates for bioassessment indicators (Reece & Richardson, 2000).…”

“…The distribution and proportion of FFG within a stream are influenced by the availability and amount of specific food resources (Vannote et al, 1980). Changes in the distribution of FFGs in spatial scale denote variations in the food base's environmental conditions (Park et al, 2008).…”

Functional feeding group (FFG) is an approach that classifies macroinvertebrates based on their utilization of organic matter food resources. Across streams and rivers, variations in the distribution of FFGs reflect the unequal distribution of food resources, which are affected by varying environmental conditions and disturbances to the ecosystem. In the tropics, the distribution of FFGs does not follow the pattern observed in temperate streams. This study aims to (1) determine the FFGs present in selected Philippine tropical streams, (2) assess the variations in FFG distributions and how the distributions vary across space, and (3) evaluate how FFG distributions are affected by certain environmental factors and habitat structure. Benthic macroinvertebrates were collected in 2010 from five sites and assigned to their primary FFG based on published literature. Across study sites, the macroinvertebrates collected were classified into gathering collectors (total n = 4,640), scrapers (n = 1,670), filtering collectors (n = 1,545), predators (n = 632), and shredders (n = 270). Within and between sites, these FFGs varied significantly. Variations explained the upstream-downstream and north-south variations in the mean of FFG abundance in width and depth of the stream, discharge, temperature, pH, riparian vegetation, and habitat stability and variability. This study reveals that the FFG approach is a useful bioassessment tool in tropical aquatic systems. However, there is still a need for verification of the findings in other streams and seasons.
