Abstract
Elaeocarpus venustus is an endemic as well as endangered tree species habitated in the wet evergreen forests of Southern Western Ghats (SWG), India. Due to insufficient natural regeneration, low seedling tendency, and prevailing anthropogenic disturbances, their distribution has been shrinking in their native environment. Towards conserving this endangered species, we have attempted to propagate E. venustus in its habitat by adopting vegetative propagation techniques of cutting and air layering through growth hormones. Significant growth has been observed by providing 2 mM concentration of indole-3-butyric acid (IBA) for both cutting and air layering. Higher rooting response has been observed through cutting and air layering techniques during monsoon periods. Based on the results of the study, we suggest that the cutting and air layering techniques can be employed as promising strategies towards the in situ conservation and promotion of Elaeocarpus venustus tree species as well as other endangered species in Western Ghats.

Abstract
Human utilization of natural resources acts as a main driver in altering the ecosystem service and functions. Apart from indirect influence, these human activities also tempt for the behavioral shift in insects especially in honey bees. The foraging behavior of honey bees from the natural floral resources to the man-made food sources eventually degrade the ecosystem's services and cause declining of the honey bee population. Understanding this foraging behavior of bees could help in opting for viable conservation measures for honey bees. In order to understand the influence of human utilization of natural resources on the foraging behavior of bees and its negative impacts on the bee population, the study was carried out in the sites where humans collect palm sap. Palm sap collectors used different containers (mud pots and pet bottles) to collect the palm sap from Borassus flabellifer. The number of containers per tree, volume of palm sap per container/tree, bee visiting frequency, and bee mortality per container/tree were measured at different ecosystems. Palm saps were collected freshly and volatile compounds of samples were identified using FT-IR and GC-MS analysis. The identified volatile compounds were used to study the interaction between volatile compounds and odorant-binding proteins (OBPs) of honey bees for understanding the foraging behavior of bees using in silico approach. Our results clearly showed that bee visitation frequency was directly correlated (0.94) with bee mortality in palm sap in different study sites. The average number of bee mortality was recorded as 491.2 ± 23.48 bees per container/tree/day. GC-MS analyses revealed the presence of 35 volatile compounds in collected palm sap from different study sites. Furthermore, molecular docking studies were performed for all 35 palm volatile compounds OBPs of honey bees to analyze their binding affinities. Docking studies showed that 1-methylbutylmandelate and 6-(hydroxymethyl)-1,4,4-trimethylbicyclo [3.1.0] hexan-2-ol have high binding affinity with OBP residues of bees. These volatile compounds might act as an attractant for bee populations for their foraging behavior. Based on this study, we conclude that human utilization of palm sap has created new ecological niches which highly alters the foraging behavior of bees and results in declining bee populations.

Abstract
Analysis of honeybee PBPs is of interest in the development of Biosensor applications. We described the predicted binding of 19 such
compounds with 43-honey bee OBPs using molecular modeling, docking and phylogenetic analysis. Therefore, training the honeybees
using preferred compounds formulate the bees to identify the illicit drugs and bomb compounds. Consequently, high docking score
produced complex such OBP16-N-Phenyl-2-Napthalamine (-12.25k/mol), 3BJH-Crack Cocaine (-11.75k/mol), OBP10-Methadone (-
11.71k/mol), 1TUJ-Dronobinal Cannabis (-11.66k/mol), OBP13-Plasticizer (-11.27k/mol) and OBP24-Ecstasy (-10.89 k/mol) can be
used to identify the compounds using biosensor application. The chemical reaction of the compounds for olfactory sensory was
analyzed using DFT (Density Functional Theory) studies. Some of these compounds show high binding OBPs across distant
phylogeny.
