Background: Oecophylla smaragdina is distributed from India, SE Asia and Australia including many tropical Islands. A recent phylogenetic study based on mitochondrial DNA analysis reveals that Bangladesh is the overlapping zone of both Indian and Southeast Asian type of O. smaragdina. These two different lineages of Indian and SE Asian type have the opportunities of creating the zone of contacts, but no such data was found. In this study, shed light was given to reveal the chance of hybridized colony of O. smaragdina in Bangladesh. Methods: To asses the hybridization scenario, 28 O. smaragdina colony from 27 localities in Bangladesh were analyzed using Longwave length Rhodopsin (LWRh) nuclear gene sequences and was compared with the mtDNA sequences, which was collected from the same localities and deposited into NCBI GenBank. Results: The inconsistency between mitochondrial and nuclear gene types was observed from two colonies of the overlapped zone of contact. These two colonies were identified as SE Asian type by mtDNA analysis however, by nuclear DNA analysis; it was identified as Indian type. These significant discrepancies within the colony suggested the possibility of hybridization of weaver ant in Bangladesh.

The frog genus Microhyla was considered as the South, East, and Southeast Asian frog species. Microhyla orientalis was described in 2013, distributed in Java and Bali, Indonesia. Thenceforth, it was known as the easternmost distribution of this genus within the oriental region, but recently this species was recorded from the Timor Island and Sulawesi on the Wallace regions. We applied molecular analysis to evaluate the taxonomic status  and the origin of the Wallacean population. Phylogenetic analysis using the partial 16S mitochondrial gene demonstrated that the Java, Timor and Sulawesi populations were not significantly different from the Bali population. This Wallacean population of M. orientalis was originated from Java and possibly it is accidentally distributed by humans through the expansion of agricultural activity.

Abstract. Ever since Fredrickson and Roberts (1997) proposed objectification theory, research on self-objectification and – by extension – other-objectification has experienced a considerable expansion. However, most of the studies on sexual objectification have been conducted solely in Western populations. This study investigates whether the effect of target sexualization on social perception differs as a function of culture (Western vs. Eastern). Specifically, we asked a Western sample (Belgian, N = 62) and a Southeast Asian sample (Thai, N = 98) to rate sexualized versus nonsexualized targets. We found that sexual objectification results in dehumanization in both Western (Belgium) and Eastern (Thailand) cultures. Specifically, participants from both countries attributed less competence and less agency to sexualized than to nonsexualized targets, and they reported that they would administer more intense pain to sexualized than to nonsexualized targets. Thus, building on past research, this study suggests that the effect of target sexualization on dehumanization is a more general rather than a culture-specific phenomenon.
