Body size was measured for 67 of the approximately 120 invertebrate species on Marion Island. These include more than 60% of the 29 acarine families, and more than 80% of the remaining terrestrial invertebrate species. Thus the data are regarded as representative of the entire invertebrate fauna of sub-Antarctic, Marion Island. Length–mass and fresh–dry mass relationships were calculated for orders, families and species to provide a means of estimating body size parameters for species in collections and those which are known from only a few specimens. A comparison of the regression slopes for the different taxonomic ranks indicates that it is better to use regressions from the lowest possible taxonomic level for prediction of body mass. Differences between length–mass relationships for Marion Island insects and continental assemblages raises the question as to the applicability of continental regressions to sub-Antarctic species. This study provides a useful means for estimating body size parameters for Antarctic and sub-Antarctic invertebrates and provides baseline data on an important species trait that seems to be changing with local and global environmental changes.

As millennial workers enter and dominate the global workforce by 2025, understanding their leadership styles is vital to bring about higher level of performance and productivity in the workplace. The Millennials, the next generation of leaders, are entering the workforce and assuming leadership positions in a relatively short period. More often, they found themselves leading employees that are older than themselves and yet their leadership traits and styles are not fully understood. The study explores factors affecting leadership styles of millennial managers and how they are manifested and applied in managing and resolving conflict involving older subordinates. Using a qualitative approach, it employs interviews, participant observation, and prolonged engagement with four millennial managers from the National Food Authority in the Philippines as they lead, manage, and interact with their older staff. Data collected were triangulated by document analysis and interview of the millennial managers’ subordinates themselves. The results of the study show that the participants’ leadership competencies are in the early stages of development. The participants consider building good impression and rapport highlighting the importance of soft skills in leadership, strong sense of respect, reverse mentoring, delegation of tasks, and the ability to handle expectations and performance as factors in managing older employees. This study draws the attention to examining the leadership attributes and potentials of Filipino millennial managers in the context of Philippine workplace culture using insights from Public Administration, Social Sciences, and Psychology.

The development of new technology for food production is essential to sustain man's needs for survival. The use of farmlands for food production and industrial purposes goes beyond the carrying capacity of the environment. The study determined the applicability of Vertical Farming using Hydroponic Technology to onion production in Nueva Ecija, Philippines. The country is known as the onion capital of Southeast Asia. The study measured the technology's sustainability and acceptability to onion farmers. By using experimental method, interview, and Focused Group Discussions (FGD), the study established its viability. Three phases of field experiments were conducted in August 2016, May 2017 and July 2017 using the Vertical Farming and Hydroponics Technology and Single Factor Analysis of Variance. The results showed that there is significant difference in the growth of onion bulb per week and the suitability and comparability of the technology to conventional farming. The study concluded that the VFH technology is acceptable to most onion farmers except the aspect of the cost of initial investment which requires government subsidy for the ordinary onion grower to avail of this new and sustainable technology in onion production.
