Aarey Milk Colony (AMC) is 16km2 of forested area, acts as a buffer to the Sanjay Gandhi National Park, Mumbai. It has gardens, lakes, recreation spots, and a nursery. It also harbors 32 cattle farms, animal husbandry centers. Apart from urbanization and forest degradation, this forest harbors great biodiversity which includes the leopard as a top predator and also lesser-known species of amphibians, reptiles, and arthropods. Considering ants as important bio indicators and the vulnerability of AMC to development plans, a study on the diversity of ants was conducted from January 2016 to May 2016. Four methods were used for data collection of ants—pitfall trap, line-transect, quadrate, and all-out search. A total of 35 species under 24 genera under six subfamilies– Myrmicinae, Formicinae, Ponerinae, Dolichoderinae, Pseudomyrmecinae, and Cerapachyinae were recorded during this study. The Simpson’s diversity index (0.88) for the pit fall trap indicates that the diversity of ants in the...

The present study unfolds the diversity of ants of Bibhutibhushan Wildlife Sanctuary, North 24 Parganas, West Bengal, India. A total of 22 species under 13 genera distributed over 5 subfamilies could be recorded. These include three newly recorded species namely Leisiota frauenfeldi (Mayr) (Formicinae), Crematogaster (Acrocoelia) hodgsoni Forel (Myrmicinae) and Brachyponera nigrita Emery (Ponerinae) from the state and nearly 90.5% of the reported species are new for the district (marked*). Analysis of their zoogeographical distribution reveals that the fauna apart from being Oriental also includes some Palaearctic (72.73%), Australian (13.63%) and Ethiopian (4.54%) elements. The dominant functional group is constituted by the Subordinate Camponotini (36.37%) followed by Generalized Myrmicinae (22.73%), Tropical Climate Specialist (13.63%), Specialist Predator (9.09%), Opportunist (9.09%) and Dominant Dolichorinae (9.09%). Ants are mostly prevalent during Monsoon (81.82%), followed by Postmonsoon (68.18%) and Premonsoon (50.00%). Two species namely Camponotus (Tanaemyrmex) compressus (Fabricius) and Oecophylla smaragdina (Fabricius) are recorded throughout the year. Ranking sequence of the most abundant species in descending order is: Camponotus (Tanaemyrmex) compressus (15.01%) = Oecophylla smaragdina (15.01%) > Crematogaster (Acrocoelia) hodgsoni (12.91%). Camponotus (Tanaemyrmex) compressus and Oecophylla smaragdina are the most dominant species. Data also reveals that both core and buffer zones conjointly offer a better combination of habitat requirement, as 12 species are common in both the zones. Highest no. of species are recorded from leaf litter and ground combined together (22 species) and 6 species are arboreal in nature. Shannon's Diversity Index (α diversity) and Simpson's Diversity Index World Scientific News 120(2) (2019) 81-110-82-both are higher in buffer zone. This reflects the habitat exploitation efficiency of the encountered species. As per Jaccard Index (β diversity) the similarity value of both the zones is only 0.55.

Ants belonging to order Hymenoptera is often thought to be a nuisance in our human life. It is a social insect and can build different nest type. But apart from one Hymenopteran species, i.e. bees which are thought to be beneficial to our ecosystem, ants are not looked upon though roughly. People are always concerned about degradation of ecosystem and its effect on large fauna. But these small organisms are often avoided. Ants though thought to be injurious; it do play essential role in day to day life as to the benefit of ecosystem. The present study tries to emphasize on the diversity profile of ants in an urban area, where different anthropogenic activities are now depleting the normal habitat of ants. Diversity study reveals that Cooch Behar is diverse in ant and a checklist of 12 genera of ant with diversity index of four study sites is provided. It also emphasizes on the fact that Site 4 should be properly restored and freed from human interference, as it shows highest ant div...

Ants are abundant insects and are considered important in ecosystem functioning they have diverse ecological role including nutrient cycling seed dispersal. This research is carried out from January 2018 to April 2018. During this research ant samples were collected from the two ecological habitats. In this finding ants of about 8 species were found different species were collected through different methods and recorded their diversity. Species such as longicornis, pharaonis, indica, C.sericus, hespera, nigra, spathifera, geminate. Among all the species longicornis has found at a greater frequency while the frequency of species indica were reported very less. While considering species richness diversified species were mostly found in the month of April followed by month of January and it was very less in February and march during this research ants were collected by using pitfall traps, scented traps and hand collection methods ants were generally collected during morning and was preserved by the wet preservation methods.

Ant sampling was carried out in different locations of the Department of Atomic Energy (DAE) Campus at Kalpakkam during dry season (March-June 2008). Pitfall traps and hand-picking methods were used to collect ants from 20 different sampling sites. A total of 31 species, 15 genera, and 5 subfamilies of ants were collected. The M yrmicinae were the most common, with 7 genera and 16 species, followed by the Formicinae (4 genera and 8 species), the Ponerinae (2 genera and 2 species), the Pseudomyrmecinae (1 genus and 4 species) and the Dolichoderinae was represented by only 1 species. Interestingly 86.6% of the genera, 83.8% of the species, and 92.4% of the indiv iduals collected belonged to three subfamilies (Myrmicinae, Ponerinae, and Formicinae). The five most species-rich genera were M onomorium, Camponotus, Tetraponera, Crematogaster and Tetramorium. The taxonomic structure of the my rmecofauna sampled, resembles that of Western and Eastern Ghats and other tropical regions in two ways: Firstly, many rare species and a few abundant species: Secondly, the dominance of subfamilies such as Myrmicinae, Ponerinae and Formicinae. The species accumulation curve indicated that the likelihood of getting more number of species in DAE campus and this finding was supported by rarefaction curve

Tropical regions are widely known for their high species diversity, which is often threatened by the growth and encroachment of human activity into natural areas. The ants of Trinidad have been studied, but most surveys and records are restricted to the Port of Spain area on the northeastern coast. Ant biodiversity is an important bioindicator, allowing us to measure the effects of ecosystem disturbances such as human interference, pollution, and climate change. This creates a way to measure changes in the ecosystem as well as potentially assessing the success of efforts to help the environment. Additionally, soil-dwelling ants often act as ecosystem engineers by creating mounds and tunnel systems. This results in important changes to soil chemical composition and can also increase soil arthropod diversity. A large portion of both terrestrial biodiversity and biomass is constituted of ants, due to their ubiquity and global distribution. This study is focused on the ant biodiversity ...

Insects

Ants are one of the largest insect groups, with the most species and individuals in the world, and they have an important ecological function. Ants are not only an important part of the food chains but are also one of the main decomposers on the Earth; they can also improve soil fertility, etc. However, some species of ants are harmful to human beings, which leads to people’s panic or worry about coming into contact with these insects during their daily home life or in their tourism or leisure activities. The presence of ants in indoor living facilities and in outdoor green spaces, parks, gardens, and tourist attractions seriously interferes with the leisure life and entertainment activities of all people (especially children). How can we control ants in these environments? Do we kill them by spraying insecticides, or do we adopt green prevention and control technology for the ecological management of ants? This topic is related to healthy life for the public and the protection of t...

We studied the diversity and abundance of the ant fauna in the canopy and on the ground of a temperate forest (Leipzig Auwald, Germany) and compared the results with those from a Neotropical forest (Surumoni, Venezuela), using similar sampling methods, aided by two identical cranes that gave us ample access to both canopies. The data suggest the presence of approximately four times less ant species in the canopy of the temperate forest compared to the tropical one. In the temperate forest, the relationship between the species richness and presence of ants on the ground versus that found in the canopy, differ to that in the tropics: In the forest at Surumoni, ants were more diverse and had a larger presence in the canopy than on the ground, whereas this was not the case in the Auwald at Leipzig. These preliminary results shows the potential gains to be collected from deeper studies in comparative ecology, assessing the relative biomass of the different components of the ecosystem in the tropics and in temperate environments.

Ants are the amazing, dominant and successful component of ecosystem, likely to be good indicators of ecosystem. The study of species richness and relative abundance of ant population and its cosmopolitan distribution is very important as they are considerable economic importance. Ants deserve a special place among the arthropod fauna to the study of ecology, including behavior, species richness, social habits and high densities. Ants are only constitute the largest chunk of the insects belonging to the endopterygote group. Up to this study 23 species of ants in 18 genera from 5 subfamilies were identified only. These ant species belong to five subfamilies, Formicinae, Myrmicinae, Ponerinae, Dolichoderinae and Pseudomyrmicinae. In Nagpur (MS) region most of the tropical, warm, and temperate genera of ants belong to the subfamilies Crematogaster, Ponerinae and Componotinae are described. The most frequently observed genus areCamponotus and Crematogaster followed by the genera Pheidole and Solenopsis.
