As a young species of 200.000 years, human is part of earth ecosystem. For 3.8 billion years, other livingbeings have evolved, adapting and selected by nature, until we came and disrupt the balance. Populationgrowth and climate change impact all of earth’s ecosystem. Urbanization and deforestation resulted in floodingin parts of Indonesia. Flooding is worse in urban areas as more risks involved. The Search and Rescueoperation can benefit from remote controlled unmanned vehicles to help save people. Conventional propulsionuses propeller, however in urban flooding condition, there are lots of debris in the water and the propeller canget stuck. Biomimicry uses nature’s genius to solve problem with emphasis on sustainability. This approachseeks nature’s advice in designing an alternative solution to the propeller problem in certain condition. Mobuliformswimmers, such as Manta Rays, present a model of efficient and debris-proof propulsion that can be used inthe search and rescue unmanned vehicles. This paper will highlight the Biomimicry process in designing aSearch and Rescue vehicle, called RCM3D-SAR that uses inspiration from Manta Ray’s pectoral fins. Thedesign is based on additive manufacturing technology and form follows function approach.

The planktonic protist interactome: where do we stand after a century of research?

Microbial interactions are crucial for Earth ecosystem function, but our knowledge about them is limited and has so far mainly existed as scattered records. Here, we have surveyed the literature involving planktonic protist interactions and gathered the information in a manually curated Protist Interaction DAtabase (PIDA). In total, we have registered ~2500 ecological interactions from ~500 publications, spanning the last 150 years. All major protistan lineages were involved in interactions as hosts, symbionts (mutualists and commensalists), parasites, predators, and/or prey. Predation was the most common interaction (39% of all records), followed by symbiosis (29%), parasitism (18%), and ‘unresolved interactions’ (14%, where it is uncertain whether the interaction is beneficial or antagonistic). Using bipartite networks, we found that protist predators seem to be ‘multivorous’ while parasite–host and symbiont–host interactions appear to have moderate degrees of specialization. The SAR supergroup (i.e., Stramenopiles, Alveolata, and Rhizaria) heavily dominated PIDA, and comparisons against a global-ocean molecular survey (TARA Oceans) indicated that several SAR lineages, which are abundant and diverse in the marine realm, were underrepresented among the recorded interactions. Despite historical biases, our work not only unveils large-scale eco-evolutionary trends in the protist interactome, but it also constitutes an expandable resource to investigate protist interactions and to test hypotheses deriving from omics tools.

Here, we have surveyed the literature involving planktonic protist interactions and gathered the information in a manually curated Protist Interaction DAtabase (PIDA). In total, we have registered ~2,500 ecological interactions from ~500 publications, spanning the last 150 years. All major protistan lineages were involved in interactions as hosts, symbionts, parasites, predators and/or prey. Symbiosis was the most common interaction (43% of all records), followed by predation (39%) and parasitism (18%). Using bipartite networks, we found that protistan predators seem to be “multivorous”, while parasite-host and symbiont-host interactions appear to have moderate degrees of specialization. The SAR supergroup (i.e. Stramenopiles, Alveolata and Rhizaria) heavily dominated PIDA, and comparisons against a global-ocean molecular survey (TARA Oceans) indicated that several SAR lineages, which are abundant and diverse in the marine realm, were underrepresented among the compiled interactions. All in all, despite historical biases, our work not only unveils large-scale eco-evolutionary trends in the protist interactome, but it also constitutes an expandable resource to investigate protist interactions and to test hypotheses deriving from omics tools.

Modeling Permafrost's Role in the Global Carbon Cycle

A team of international scientists surveyed an array of Earth ecosystem models, recommending several ways to reduce uncertainties.

The Earth Ecosystem In The Region Of Gjirokastra

The earth ecosystem in the region of Gjirokastra is the greatest earthbound potential because it protects the ground, the microclimate, the agricultural crops, favors tourism and re-creation. The ecosystem of Gjirokastra region has been changing after 1990 as a result of wide historical, socio-economical, political and demographical factors. The multifunctional, sustainable and integrated use of ecosystem is very necessary; able to realize the dynamic development, which actually is exposed to danger. The existence of original and intrude forests is of a great importance.
