“…The subfamily Ponerinae stands out for its richness and abundance in samples already taken in Conservation Units and forest fragments in southern Brazil (Lutinski et al, 2018). The genera Pachycondyla (S = 6) and Hypoponera (S = 5) richness is similar to that obtained in other studies performed in the same region (Cantarelli et al, 2015;Rizzotto et al, 2019).…”

“…The composition and richness of ant assemblages sampled in this study reflects the accumulated knowledge about the myrmecofauna occurring in southern Brazil (Ulysséa et al, 2011;Diehl et al, 2014;Dröse et al, 2017). The most species-rich subfamilies in samples from the Turvo State Park, Myrmicinae, Formicinae, Ponerinae and Dolichoderinae, corroborates Lutinski et al (2018). The richness of the subfamily Mymicinae predominate in ant samples of the States of Santa Catarina, Paraná, and Rio Grande do Sul (Ulysséa et al, 2011;Diehl et al, 2014;Lutinski et al, 2016;Dröse et al, 2017;Rizzotto et al, 2019).…”

The knowledge of ant assemblages that occurs in Conservation Units in the Atlantic Forest domain is a priority, considering the number of endemic species and the impacts that this biome has been suffering. The aim of this study was to evaluate ant assemblages in the Turvo State Park, which is the largest conservation unit in the State of Rio Grande do Sul and presents an important role on biodiversity protection. Two samplings were conducted in 2019, one in the summer (January) and the other in the spring (November and December), at five sites 2 km apart, with pitfall traps (soil and canopy), sardine baits, glucose, beating net, sweeping net and manual collection. We sampled 121 species in the summer and 120 in the spring, totaling 163 ant species. A total of 78 species (47.8%) occurred in both sampling seasons. The richest genera in the study were Camponotus (S = 30), Pheidole (S = 23) and Linepithema (S = 11). Seventeen species were recorded for the first time for Rio Grande do Sul state. The results indicate that this is one of the most species-rich assemblages of ants ever surveyed in a conservation unit in southern Brazil. The study highlights the importance of Conservation Units as protected environments against habitat loss for ant biodiversity. The results of this study contribute to myrmecofauna knowledge and serve as a basis for environmental impact studies, management plans and conservation of Atlantic Forest remnants.

The objective of this work was to evaluate ant species interacting with mealybugs in sugarcane plantations, the frequency of occurrence, and the effects of the interaction with ants on mealybug population size. The data was collected in a sugarcane plantation area in Seropedica, Rio de Janeiro, Brazil. The insect species were collected from 70 thoroughly inspected sugarcane plants and the nature and frequency of the interactions were evaluated. The effect of the interaction with ants on mealybug abundance was evaluated by counting the number of adult females of each mealybug species on ten plants isolated and ten plants not isolated from ants. Two mealybug species were collected: Aclerda takahashii (Kuwana, 1932) and Saccharicoccus sacchari (Cockerell, 1895). Ten and seven ant species were found interacting with A. takahashii and S. sacchari, respectively, which were distributed among six genera; the most frequent genera were Crematogaster and Camponotus. Three ant species interacted exclusively with A. takahashii, whereas the others interacted with both mealybug species. The abundance of A. takahashii females was significantly higher on non-isolated than on isolated plants (Paired t-test; t = 2.34; p = 0.04). However, no significant difference in S. sacchari abundance was found between isolated and non-isolated plants (t = 0.27; p = 0.8), nor for the two species combined (t = 1.9; p = 0.09). Thus, ant species that interact with mealybugs in sugarcane plantations cause increases in A. takahashii populations which, at a larger scale, can reduce crop yield.

To accelerate the monitoring and counting of biodiversity of various species, there is a need for automating the process of computing biodiversity. The calculations of the alpha and beta biodiversity indexes are fundamental for the analysis of ecological and biodiversity studies. Sukhna and Dhanas lakes, India are critical for the maintenance of the health of the residents and aquatic life thriving in them. Both lakes are prone to pollution. Due to these factors, there is a need for building digitized infrastructure for monitoring the health of these lakes. Hence in this research work, an automated algorithm has been devised for the computation of biodiversity of microorganisms. The work focuses on the surface water of both these lakes. The automation of biodiversity computation is done with image processing algorithms and is applied to the primary data collected. From this study, it is apparent that the counting of microorganisms using image processing algorithms is an easier and efficient way for biodiversity studies as compared to the manual process of estimating the population of microbes. The results show that the species richness of Dhanas Lake is more as compared to Sukhna Lake. The dissimilarity between the two lakes is five species as per the primary data collected. This shows that the biodiversity of Dhanas Lake is better than the Sukhna Lake but it is prone to harmful algal blooms. This may be attributed to the fact that Dhanas Lake may have multiple sources of pollution that need to be identified.
