Fireflies in South East Asia: Species Diversity, Distribution, and Habitat (2015-2021)

Abstract

The information on soil physicochemical properties is vital for the optimum wood biomass production in forest plantation management. The objective of this study was to determine the topsoil physicochemical properties under different Acacia mangium stand ages and their effect on the growth parameters. Five plots were established randomly within each five different stand ages. In all sample plots, the diameter at breast height (DBH) and the total height of standing trees were measured. Soil samples were collected at a depth of 0 to 20 cm at three random points in each plot, then mixed to get a composite before determining physical and chemical properties. DBH mean and the total height of A. mangium increased as stand age increased. The mean annual volume increment maximised at the 8.5 years old stand with 27.9 m3 ha-1 yr-1. Survival rate and stem density decreased as stand age increased. Principal component analysis (PCA) results showed that the most important soil physical properties were soil organic matter, silt and sand contents, bulk density, and moisture content. For soil chemical parameters, exchangeable magnesium (Mg), cation exchange capacity (CEC), total carbon (TC), total nitrogen (TN), and carbon-to-nitrogen (C/N) ratio were the influential soil variables. Soil pH, available phosphorus (P), and clay content were negatively correlated with the growth development of A. mangium trees. Observations suggest that multiple soil variables are essential for the success of the A. mangium plantation.

New distributional records of fireflies (Coleoptera, Lampyridae, Luciolinae) from two Eastern States of India with notes on their biology and an updated Indian checklist

“… aquatilis (India, Laos, Thailand, Vietnam) and Scl. substriata (India, Myanmar, Sri Lanka) ( Gorham 1880 , Ballantyne et al 2013 , Ballantyne et al 2016 , Ballantyne et al 2019 , Seri and Rahman 2021 ) have demonstrated scattered distribution which is revealed by their presence in fewer countries of this global subregion.…”

Some Abiotic and Biotic Factors Influencing Firefly Population Abundance in Southeast Asia: A Review

“…In Southeast Asia and the Indo-Pacific region, over 400 species have been identified, most of which are members of the Luciolinae family (Ballantyne et al, 2015). Seri and Rahman (2021) successfully identified 145 firefly species across Southeast Asian countries (including Malaysia, the Philippines, Indonesia, Cambodia, Myanmar, Singapore, Sri Lanka, Papua New Guinea, Laos, Thailand, and Vietnam). At the same time, the authors were also unsuccessful in locating studies in Brunei.…”

“…At the same time, the authors were also unsuccessful in locating studies in Brunei. Additionally, they noted that data on firefly species found in countries such as the Philippines, Indonesia, Cambodia, Myanmar, Singapore, Sri Lanka, Papua New Guinea, Laos, and Vietnam is extremely outdated due to the country's lack of research (Seri & Rahman, 2021). Regretfully, there has been a decline in the distribution and abundance of numerous firefly species during the previous few decades (Lauff, 2017;Lloyd, 2018).…”
