“…Families such as Comesomatidae, Linhomoeidae and Sphaerolaimidae and some genera (Sabatiera, Sphaerolaimus, Terschellingia, and Daptonema) usually dominate mudflat sediments (Travizi, 2010). A recent study by Bhadury et al (2015) on nematode assemblages in the central west coast of India had similar findings. In this study, Sphaerolaimus and Daptonema had dominated mangrove habitat comprising of mudflat sediments.…”

Nematodes present in all substrates and sediment types with an enormous number of species. The studies on free-living marine nematodes are still limited in Malaysia. The present study provides general information on genus checklist of free-living marine nematodes in the northern part of Peninsular Malaysia in a different ecosystem which are intertidal zones of estuarine, sandy beach and mangrove ecosystems. Samples were randomly collected at three stations in each ecosystem. A total of 34 genera (22 families and ten suborders) were recorded in three ecosystems. Each ecosystem had common genera which also commonly found worldwide. Viscosia genus was observed in all three ecosystems. The nematode genera of Estuary and mangrove ecosystems had greater similarities than those in the sandy beach.

“…dominated the clean high-energy beach, the Northwest Coast (CHE, 26.26%, Table 8). Bhadury et al (2015) and all references therein stated that the Oncholaimus genus is dominant in a sandy environment, probably due to its large body size and feeding habits (omnivores/predators). Sahraeian et al (2020) documented its sensitivity to pollution.…”

Nematode functional traits and community structure approaches are receiving attention and being debated regarding the similarity in gained information. This work applied two nematode methods (i.e. functional traits, community structure) and sex ratios to investigate sandy beaches experiencing physical disturbances and anthropogenic stressors along the Alexandrian coast of Egypt. It is the first study to identify the Egyptian marine benthic nematodes to genus level yielding fourteen genera. This study addressed the following questions. (A) Which analyses of functional traits, community structure, or sex ratio could distinguish beaches experiencing natural disturbances from anthropogenic stressors? (B) What are the driving forces that govern nematode assemblages? Designated beaches were high pollution and energy (HPHE), high pollution but low energy (HPLE), and clean high energy (CHE). The study was conducted in March 2014, applying a stratified random sampling design and advanced multivariate analyses. Results revealed significant discrimination among and within beaches based on functional traits, community structure, and sex ratio. The functional traits (FBM) grouped data into two main groupings, predators and scavengers. Predators and cylindrical shape-tail types were found in high salinity moderately-sorted fine-grained sand dominant at HPHE and CHE. Scavengers and a variety of tail-shape types inhabited low saline water with well-sorted coarse sediment at HPLE. The community structure (CSM) revealed three groupings, as each beach had a specific assemblage based on its response to the measured physiochemical factors (salinity, pH, and temperature). Three genera were responsible for the high contribution across each beach Graphonema sp (HPHE), Enoplolaimus sp. (HPLE), and Oncholaimus sp. (CHE), as well as the co-sharing of Axnolaimus sp at HPLE. However, Axnolaimus sp and Oncholaimus sp showed the highest dissimilarity among beaches. The contribution of the measured factors was 53.8% (FBM) and 35.7% (CSM). Trophic guilds were anthropogenic stressors dependent and tail-shape type physically disturbing-related. However, nematode genera were species-specific to habitat type. The sex ratio was male-biased, and Juvenile-stages seemed to be temperature-dependent. The dissimilarity in the functional trait and community structure data recommend their application in biomonitoring and coastal restoration programs.

“…Accordingly, the focus of Indian meiofaunal studies has been on the ecological aspects and qualitative analysis of meiofauna is mostly restricted to group level identification. Very few studies were dedicated to the taxonomy, especially the species level identification of a particular meiofaunal groups such as halacarid mites (Chatterjee et al, 2012;Chatterjee et al, 2013;Chatterjee, 2015aChatterjee, , 2019, nematodes (Sinha et al, 1985(Sinha et al, , 1987(Sinha et al, , 1989Chinnadurai, Fernando, 2006a, c, 2007bBhaduri et al, 2015;Parsath et al, 2017;Ansari, Bhadury, 2017), harpacticoid copepods (Kondalarao, 1984;Ingole, Ansari, Parulekar, 1990) and foraminifera (Rajeshwararao et al, 2012) but among them also some studies only listed name of the species without any taxonomic detail.…”

“…They reported 59 species belonging to 32 genera. Bhaduri et al (2015) provided a list of free-living nematode species recorded from the selective sandy beach sediments, including some collections from the estuarine -mangrove regions. Ten families, 16 genera and 24 species were encountered from the muddy mangrove sediments.…”

In spite, of being the most threatened coastal habitats in the world, mangrove ecosystems offer a host of goods and services to the coastal communities. With over 4,975 sq.km of the mangrove area, India has the largest mangrove in Asia that constitutes about 45% of the total mangrove cover in South Asia. Mangroves are ecologically significant for their role in shoreline protection but it also acts as important reservoirs of biodiversity comprising both terrestrial and aquatic species. In the present communication, we reviewed the published literature on meiofauna found associated with mangroves. These microscopic organisms occur in very high densities in mangrove sediment and thus constitute a major component of the diet of commercially important fish and prawn larvae. In addition to the importance of meiofauna in the benthic food chain, larval feeding, meiofauna is also used very effectively in coastal environmental monitoring. While a significant number of scientific reports are published involving studies on meiofauna of Indian mangroves, the majority of these studies have focused only on the phylum of taxon or group level identification. Moreover, only a few of the studies have highlighted the role of food availability and abundance of meiofauna within the mangrove mudflat. Consequently, we recommend that future studies should explore the role of meiofaunal species, especially the dominant taxa, in the mangrove ecosystem functioning. Trendy w badaniach meiobentosu namorzynowego w Indiach: przegląd Słowa kluczowe meiofauna, namorzyny, Indie, trendy badawcze Streszczenie Pomimo tego, że są najbardziej zagrożonymi siedliskami przybrzeżnymi na świecie, ekosystemy namorzynowe oferują społecznościom przybrzeżnym wiele dóbr i usług. Z ponad 4975 km 2 powierzchni namorzynów, Indie mają około 45% całkowitej pokrywy namorzynowej w Azji Południowej. Namorzyny mają znaczenie ekologiczne ze względu na swoją rolę w ochronie linii brzegowej, ale pełnią również funkcję ważnych rezerwuarów różnorodności biologicznej obejmującej zarówno gatunki lądowe, jak i wodne. W niniejszym komunikacie dokonaliśmy przeglądu opublikowanej literatury dotyczącej meiofauny związanej z namorzynami. Te #0# mikroskopijne organizmy występują w bardzo dużym zagęszczeniu w osadach namorzynowych, a zatem stanowią główny składnik diety larw ryb i krewetek ważnych z handlowego punktu widzenia. Oprócz znaczenia meiofauny w bentosowym łańcuchu pokarmowym, żerowania larw, meiofauna jest również bardzo skutecznie wykorzystywana w monitoringu środowiska przybrzeżnego. Chociaż opublikowano znaczną liczbę doniesień naukowych dotyczących badań nad meiofauną indyjskich namorzynów, większość tych badań skupiała się jedynie na identyfikacji taksonów. Co więcej, tylko kilka badań podkreśliło rolę dostępności pożywienia i obfitości meiofauny w murawach namorzynowych. W związku z tym zalecamy, aby w przyszłych badaniach zbadać rolę gatunków meiofaunalnych, zwłaszcza taksonów dominujących, w funkcjonowaniu ekosystemu namorzynowego.
