Wetlands are a natural habitat for endemic animals of South Kalimantan, namely proboscis monkeys (Nasalis larvatus). These primates are one indicator in wetlands conservation, but now the status of proboscis monkeys is endangered which means wetlands are naturally also damaged. This makes The Indonesian Proboscis Monkey Friends Foundation worried about the preservation of these primates who are endangered in a side the number of foreign researchers who are interested in proboscis monkeys so it also weakens status proboscis monkeys as endemic animals.The Indonesian Proboscis Monkey Friends Foundation wants the proboscis monkey in South Kalimantan to become an identity in the area along with the wetland ecosystem which is the habitat of proboscis monkeys. Therefore a fundamental problem with the design of the Proboscis Monkey Research Station on Wetlands is how the design of the proboscis research station on wetlands is in harmony with natural conditions around it so that it can become the identity of the region. Settlement the problem was solved through the metabolism-organic method and the visual identity-metaphor method. The metabolism-organic method is the solution to the problem of harmony building with nature, while the visual identity-metaphor method is the solution in the matter of regional identity. Based on the two methods, the concept proposed for this design is the concept of "subject-object interaction" which is realized through the concept of "wetland ecology". This concept of "subject-object interaction and wetland ecology" is a concept that elevates interactions between researchers and wetland organisms such as proboscis monkeys by entering the wetland elements into the design of this research station.

AbstractThe forces that are developed when manipulating objects generate sensory cues that inform the central nervous system about the qualities of the object’s surface and the status of the hand/object interaction. Afferent responses to frictional transients or slips have been studied in the context of lifting/holding tasks. Here, we used microneurography and an innovative tactile stimulator, the Stimtac, to modulate both the friction level of a surface, without changing the surface or adding a lubricant, and, to generate the frictional transients in a pure and net fashion. In three protocols, we manipulated: the frictional transients, the friction levels, the rise times, the alternation of phases of decrease or increase in friction to emulate grating-like stimuli. Afferent responses were recorded in 2 FAIs, 1 FAII, 2 SAIs and 3 SAIIs from the median nerve of human participants. Independently of the unit type, we observed that: single spikes were generated time-locked to the frictional transients, and that reducing the friction level reduced the number of spikes during the stable phase of the stimulation. Our results suggest that those frictional cues are encoded in all the unit types and emphasize the possibility to use the Stimtac device to control mechanoreceptor firing with high temporal precision.

The distribution of a species can help guide the protection activities in their natural habitat. Conversely, the lack of information on this distribution makes the protection strategy of this species difficult. The research was conducted in Way Canguk Research Station, Bukit Barisan Selatan National Park from January until March 2018. The purposes of this research were to create a distribution prediction map of Sunda pangolin (Manis javanica) and estimating the environment variables that most influenced the probability of the distribution. Fourteen points of camera trap coordinates were used for presence data with nine types of environment variables such as elevation, slope, understorey, canopy cover, distance from roads, distance from rivers, distance from villages, food source, and distance from the threat. The result of maxent showed an Area Under the Curve (AUC) value of 0.909 categorized as very good. The highest probability of Sunda pangolin distributions was in the Pemerihan Resort and Way Haru Resort area, while the dominant environmental variables included the distance from the village, the canopy cover, and the distance from threat with the value 47.7; 25.85; and 15.8%, respectively. Prediction maps and environment variables can help to identify the population of Sunda pangolin in the wild and can provide input for the national parks to prioritize protection areas for Sunda pangolin from the increased poaching.

A wasp mimicking praying mantis (Mantodea) of the early evolving Mantoididae family was discovered in 2013 at a research station near the Amazon River in Northern Peru. This adult specimen exhibited a striking bright red/orange and black coloration pattern that was undocumented in all known praying mantis species. We tested the status of this new specimen using external morphology, male genital dissections, and geographic distribution. Our findings demonstrate the specimen to represent a new species, Vespamantoida wherleyi gen. nov. sp. nov., that is closely allied with a recently described species, Mantoida toulgoeti Roy, 2010, both of which are included within the newly erected genus. To support our actions, we present high resolution images of museum preserved and living specimens, morphological illustrations, a generic-level distribution map, and recorded video of the behavior of the holotype taken in the field at the time of collection. The bright red/orange coloration contrasted with black markings, the general appearance of a hymenopteran that includes a narrowed wasp waist, and the locomotory patterns and antennal movements mark this newly discovered species as unique among all hymenopteran mimicking Mantoididae as well as all other praying mantises.

A warming climate poses a fundamental problem for embryos that develop within eggs because their demand for oxygen (O 2 ) increases much more rapidly with temperature than their capacity for supply, which is constrained by diffusion across the egg surface. Thus, as temperatures rise, eggs may experience O 2 limitation due to an imbalance between O 2 supply and demand. Here, we formulate a mathematical model of O 2 limitation and experimentally test whether this mechanism underlies the upper thermal tolerance in large aquatic eggs. Using Chinook salmon ( Oncorhynchus tshawytscha ) as a model system, we show that the thermal tolerance of eggs varies systematically with features of the organism and environment. Importantly, this variation can be precisely predicted by the degree to which these features shift the balance between O 2 supply and demand. Equipped with this mechanistic understanding, we predict and experimentally confirm that the thermal tolerance of these embryos in their natural habitat is substantially lower than expected from laboratory experiments performed under normoxia. More broadly, our biophysical model of O 2 limitation provides a mechanistic explanation for the elevated thermal sensitivity of fish embryos relative to other life stages, global patterns in egg size and the extreme fecundity of large teleosts.

Abstract The relations between man and nature constitute an immemorial subject of the geographical research. Man, while striving to understand the surrounding world and its secrets, simultaneously alters and transforms it. The importance of knowing the rules of rational functioning in the natural environment, especially in the modern, globalized world is proven by it being a subject of schooling at all education levels. The purpose of the students gaining knowledge on the natural environment and the rules of its normal functioning in order to provide a balanced development thereof, is also meant to shape appropriate attitudes, consciousness and responsibility for the natural environment, both in the global and local aspects. Therefore, an attempt to determine the significance of the natural environment in shaping the sense of local identity in young people has been made. Studies on the local and regional identity have been conducted with the high schoolers from the Łódź voivodeship using the survey method. The results of the research allowed to determine the level of knowledge on the natural environment in the area of the students’ places of residence, including the areas protected by law. A high importance of natural values in shaping the pride of a person’s place of residence was also proven. Moreover, it turned out that the advantages of the natural habitat are in a high position in terms of areas considered “magical places”. The natural environment values are more likely to shape local identities in students residing in rural areas, in a direct neighbourhood of protected areas, forests or rivers.

In 2012, The Philippine National Aquasilviculture Project (PNAP) was forged and formally launched by the Department of Agriculture - Bureau of Fisheries and Aquatic Resources (DABFAR). To implement the PNAP, a Memorandum of Agreement (MOA) was executed by and between BFAR and the Commission on Higher Education (CHED) on December 16, 2011. The study was conducted to assess the status and development of the PNAP program implemented in Southern Negros, at four (4) Municipalities and two (2) Cities. The BFAR downloaded a total fund amounting Php 10,148,812.50 for the four (4) phases of the program wherein, the Php 6,422,762.5 was spent for resource rehabilitation (mangrove planting); Php 845,000.00 for Aquasilviculture; Php 1,140,000.00 for Multi-species hatchery and Php 1,741,050.00 for administrative costs. The total paid mangrove propagules planted in Southern Negros was 978,000 with 30% buffer with a total of 1,144,260 survived propagules planted in 130.4 hectares of coastal land in Southern Negros and commensurate 673 direct beneficiaries. The 274 fisherfolk beneficiaries augmented income from Aquasilviculture project while a total of 1,284 berried wild bluecrab which estimated to produce up to 2 million eggs have been reared in Multi-species hatchery. A conservative estimate of 1% survival in natural habitat under natural conditions represented the contribution of the project for the beleaguered bluecrab capture fisheries. The beneficiaries really appreciate the efforts made by CHMSC-Binalbagan as program implementer based on their responses on the given important factors of service delivery to the community.

Sygnathidae corals are included in the vurnarable category of CITES because the number in their natural habitat is decreasing. This is partly due to the high predatory activity and utilization as raw materials for traditional medicine so that it has high economic value. This research aims to study the ecological conditions including the distribution and abundance of Sygnathidae reef fish in the waters of Blue Lagoon Karangasem and to study the ecological conditions of the waters. The main marine tourism and recreation activities at Blue Lagoon Beach Karangasem, Bali are now snorkeling tours. This requires attention to the preservation of coastal ecosystems, because tourism is an industry that is very sensitive to external changes, so the region is of concern. Besides studies on marine tourism activities, scientific studies on tourism carrying capacity are also needed to determine the maximum number of tourist visitors that can still be tolerated by an ecotourism area. This research was conducted in the Blue Lagoon Coast Karangasem Bali. This study uses primary data analysis of water quality analysis, the method of determining the suitability of the region based on the multiplication of scores and weights obtained from each water brightness parameter category S1 with a score of 15, coral community cover category S3 with a score of 5, coral life form category S1 with a score of 9 , reef fish category TS with a score of 0, current speed category S2 with a score of 2, and depth of the category S3 with a score of 1. This study was conducted for 3 months, namely in June-August. The determination of the research station is based on the Purposive sampling technique. Secondary socioeconomic data obtained by questionnaire, interview / interview. The purpose of this study is to examine the suitability of the area as a marine tourism activity and analyze the carrying capacity (carrying capacity) of marine tourism areas.

Abstract A population estimation of proboscis monkeys (Nasalis larvatus) has been conducted in Manggar River, Balikpapan. In this non-conservation area, the anthropogenic activities threaten the proboscis monkey habitat. Boat survey technique was applied along ± 17 km of the river in the morning and evening. The number of proboscis monkeys in the surveyed area was estimated to range from 57 to 69 individuals with estimated population density of 4.75 individuals/Km2. Moreover, the population of this primates was divided into 4 groups and the sex ratio between adult males and females was 1:2.33. The proboscis monkeys were distributed in the middle of the river to the upstream. The highest population was found in the upstream area with less human activities. Conservation efforts in the Manggar River need to be carried out considering the proboscis monkey habitat in the area has been fragmented and isolated. These efforts could involve local economic communities.

The genus Origanum is a group of phytochemically diverse, aromatic species. Distributed mainly in Eurasia and Mediterranean, they are used in traditional medicine, cosmetics and for culinary purposes. They possess antiproliferative, antioxidant, antiviral, antiseptic, anti-inflammatory, anti-hypertensive properties. The major constituents of Origanum spp. are carvacrol and/or thymol together with ?-terpinene, p-cymene, linalool, terpinene-4-ol and sabinene hydrate. Several flavonoids and glycosides are also found. Although the Origanum spp. can either be cultivated or sourced from nature, high demand has necessitated increased production. Overexploitation from natural habitat has threatened these species. Also, due to its poor viability and small-sized seeds, cross-pollination abilities, less productive vegetative propagation, climate-dependent conventional propagation, its genetic improvement has been limited and thus scientific management of available germplasms through biotechnological approach is necessary. For in-vitro propagation, the literature review showed significant differences in culture protocols, genotypes and their success rates. Studies reported cell culture-based production of secondary metabolites or isolation of active compounds in different species of Origanum, which show antiproliferative activity in cancerous cell lines. However, significant knowledge gaps exist. The urgent need is to use advance technologies in enhancing either plant propagation thus the production of source material for active constituents or for genetic improvement of Origanum germplasms for contents, as well as to validate the therapeutic potential of Origanum constituents. This review critically appraises the status of mostly underexploited biotechnological know-how and research on highly valued medicinal herbs, Origanum and throws light on prospects and potential.

Third World Approaches to International Law (TWAIL) has a fundamental problem: its scholars don’t quite know how to relate to international law. This problem is constitutive of the theory, born as it was out of disillusionment with the failures of decolonisation and, of course, of international law. As a consequence, we find in TWAIL scholarship the juxtaposition of powerful critiques of international law alongside noisy calls for more international law. TWAIL’s aspirational projects are timid, constrained as they are by TWAIL’s overriding commitment to a legal regime its scholars bemoan. In this chapter, I propose to use counterfactuals to overcome the schizophrenia. I treat counterfactuals as a device that enables methodical explorations of alternative legal imaginaries. Contrary to Venzke, I propose exploring counterfactuals that are neither probable nor sensible within the current regime. For TWAIL, counterfactuals have value if they facilitate thinking beyond the rigidity of the status quo. And that’s the point: if TWAIL’s mission is to upend Eurocentric epistemology and practice, we must begin to imagine international law outside the parameters established by Europe.
