“…α-diversity analysis including Simpson 1/D, Shannon H’, Menhinick, Margalef and Berger-Parker indexes [ 21 , 22 ] was conducted and visualized using the vegan and fossil packages in R, respectively. Principal coordinates analysis (PCoA) was used to visually evaluate the overall difference and similarity of CAZymes between MDD and HC groups [ 23 ].…”

Major depressive disorder (MDD) is a serious mental illness, characterized by disturbances of gut microbiome, it is required to further explore how the carbohydrate-active enzymes (CAZymes) were changed in MDD. Here, using the metagenomic data from patients with MDD (n = 118) and heath controls (HC, n = 118), we found that the whole CAZymes signatures of MDD were significantly discriminated from that in HC. α-diversity indexes of the two groups were also significantly different. The patients with MDD were characterized by enriched Glycoside Hydrolases (GHs) and Polysaccharide Lyases (PLs) relative to HC. A panel of makers composed of 9 CAZymes mainly belonging to GHs enabled to discriminate the patients with MDD and HC with AUC of 0.824. In addition, this marker panel could classify blinded test samples from the two groups with an AUC of 0.736. Moreover, we found that baseline 4 CAZymes levels also could predict the antidepressant efficacy after adjusted confounding factors and times of depressive episode. Our findings showed that MDD was associated with disturbances of gut CAZymes, which may help to develop diagnostic and predictive tools for depression.

“…A total of 40 species belonging to 25 genera and 6 subfamilies were identified in the Kalaburagi district of northern Karnataka, India (Begum et al, 2021). Myrmicinae was the subfamily with the highest species richness among the other six subfamilies, followed by Formicinae, Ponerinae, Dorylinae, Pseudomyrmicinae, and Dolichoderinae.…”

Ants play a crucial role as ecosystem engineers and natural enemies of insect pests in different forests and agroecosystems. Bangladesh’s varied agroecosystem harbors a diverse ant community, it can be utilized to track recent changes to the agricultural environment. However, it’s utilization is deemed due to insufficient taxonomic checklist of ant fauna and their diversity pattern in various ecosystems in Bangladesh. This research aimed to measure the taxonomic and functional diversity of ants in an agroecosystem. Sampling was done by time-unit sampling (TUS) during March- April 2021 in different cropland habitats in Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU) campus. A total of 172 individuals of 20 genera under 5 subfamilies were identified, of which Myrmicinae was the richest subfamily with 9 genera, while Camponotus is the most dominant genus in the ecosystem. Four habitats from BSMRAU campus significantly contributed on ant species richness and diversity matrix as revealed through Principal component analysis (PCA). The functional diversity of identified ant genera was explained using the results retrieved from Shannon Diversity Index, Species Evenness index and Effective number of species (ENS). The Shannon-Wiener diversity index of Field pathway (2.5202) is highest, followed by Entomology field (2.38086), agroforestry field (1.37315) and lowest in rice field (0.16794). Field pathway had the highest value due to comprising several types of vegetation alongside and non-ploughed soil. Rice field has only rice crops that were grown in a wetland; hence, water causes the lowest value. The evenness index (>0.75) implies the probability of stable communities in all the tested habitats except in rice field (0.242), which indicates a depressed community structure and is strengthened by the ENS value as 12.4, 10.8, 3.9, and 1.18 in the field pathway, in entomology field, agroforestry field, and rice field, respectively. The findings generated a comprehensive ant checklist and diversity indices with indicator species to measure the land type transformation and restoration in the agroecosystem of Bangladesh for future research.

“…al, 2017; Bhoje et al ,2014;Begum et al, 2021) the subfamily Myrmicinea has the largest number of species, in our study, likeGhahari et al (2009), the subfamily Formicinae with 16 species from 5 genera (Camponotus, Cataglyphis, Nylanderia, Lepisiota and Plagiolepis) was the most abundant in all habitats followed by Myrmicinae with 12 species from 6 genera (Crematogaster, Monomorium, Tetramorium, Pheidole, Cardiocondyla and Messor), while subfamily Dolichoderinae is poorly recorded with only two species from one genera (Tapinoma) Ghahari et al (2009). in their revisions of ants from rice eld reported nine species from Formicinae, ve species from Myrmecinae, and one from Dolocoderinae.Torabi et al (2017) in their investigation of Ant in the vicinity of Shiraz reported 19 species belonging to 13 genera of the subfamily Dolichoderinae, Formicinae and Myrmicinae but except two species (Cataglyphis nodus and Lepisiota semenovi) none of them was found in our study.…”

Ants are a major part of the ecosystem as they assist in the decomposition process and improve soil quality. They are a great component of animal biomass and act as ecosystem engineers. We assessed the species richness and biodiversity of these arthropods in the habitats with varying degrees of human impact in Shiraz, Fars Province, southern Iran. To this end, 6 habitats (a farm, a dry land and a natural garden in the countryside, and three old gardens (Be’sat, Janat, Babakoohi) in the city) were chosen and sampled bimonthly during 2015–2106. A total of 6270 ant workers belonging to 30 species, 12 genera, and 3 subfamilies were recorded. The most specious subfamily was Formiciniae (16 Specious) followed by Myrmicinae (12 Species), and Dolichoderinae (2 Species). All biodiversity indices (Shannon wiener, Simpson and Margalof) showed a greater diversity in both natural garden and urban landscape: Be’sat and Janat garden, with the lowest amount of human effects, respectively as well as Babakoohi and the lowest in the agricultural and dry land, which had the most effect of human disturbance. Although a significant difference was observed with the habitats (F, 4.255, P = 0.004) and the months (F, 4.327, P = 0.002) of sampling, there was not a significant difference between Babakoohi, natural garden, Janat and Be’sat gardens ((P > 0.05)) nor between field and dry land (P > 0.05), and those two habitats had fewer species compared with the natural garden and city landscape. The highest Jaccard similarity index (0.773) was seen between Janat garden in the city landscape and Babakoohi and then with both Janat and Be’sat gardens (0.731); however, the lowest (0.48) was seen between dry land and Be’sat garden. The result showed that the species composition in the city landscape including different gardens is more similar than the farm and dry land. The Jaccard similarity index between dry land and farm was 0.58 which indicated the low similarity of the ant species in those regions.
