A review of shark conservation and management legal frameworks in the Philippines

Sharks are among the oldest groups of vertebrate animals, dating back to over 400 million years ago. In recent decades, fishing pressure and demand for shark products and derivatives, such as fins, meat, oil, have increased significantly, driving global declines in shark populations. Sharks are a valuable resource in the Philippines and are used for both extractive and non-extractive purposes. The primary objective of this paper is to outline international, national, and local legal frameworks that enable the management and conservation of sharks in the Philippines. This review commences by providing some background regarding the politico-legal context of the Philippines, as well as information related to shark populations, fisheries and research in this country. This paper also aims to make a case that the Philippine government is in a unique position to build on the momentum of past initiatives by passing comprehensive national shark legislation and continuing to support regulation of shark trade globally. While a national legal framework on its own cannot solve all the issues related to shark fisheries and management, it will help create and institutionalize an anchor for existing and future conservation, research, governance, and communication initiatives.

Assessment of geological diversity, geosites, and geotourism potencies at Menoreh Mountain for designation of geopark area

Menoreh Mountain area is an area with very high geological uniqueness. One of the statuses that is contextually determined is a geopark because it provides a framework for conservation, education, and sustainable local economic activities as its pillars that are relevant to the agenda of economic development. It is necessary to characterize the existing geotourism potential in Menoreh Mountain area. This research attempts to identify and develop this potential using spatial and regional complex approaches. Technically, the method used is the Modified Geosites Assessment Model (M-GAM) combined with Hot-Spot Analysis to obtain spatial and non-spatial geotourism potential clustering. Clustering is done using K-Means Cluster Analysis. The results show that the existing geosites, spatially formed a cluster and can be used to determine the theme of the tourism activity to strengthen the geopark pillars. The development of geopark is hindered by several constraints including the division of administration and the disparity of each administrative region's capability. In general, a strategy to tighten the stakeholder and optimize the research is required to initially strengthen the geopark's pilars. It is also important to build a linkage of the geodiversity with the biodiversity and cultural diversity to enhance the significance value of Menoreh Mountain.

Wildlife studies on the Tongass National Forest challenge essential assumptions of its wildlife conservation strategy

AbstractThe Tongass National Forest in southeast Alaska, USA, includes the Alexander Archipelago and narrow North American mainland, comprising one of the largest remaining, largely pristine, coastal temperate rainforest in the world. Management of the Tongass has become increasingly challenging because of expectations of a conservation framework designed to maintain viable populations of native wildlife species while decades of extensive clearcut logging of old‐growth forests has continued. We used the findings of multiple published studies conducted on the Tongass from 1998 to 2017 to examine 4 assumptions of its wildlife conservation strategy (WCS): forest planning assessments of wildlife viability were realistic, forest management and conservation policies are implemented at appropriate ecological scales, old‐growth reserves are effective habitat conservation areas and ensure functional connectivity, and forest‐wide standards and guidelines ensure sufficient habitat for sensitive species in managed landscapes. Several ecological field studies, population and spatial analyses and modeling, and statistical analyses revealed that wildlife viability assessments to evaluate forest plan alternatives underestimated the risk of extinction by only examining individual vulnerable species rather than considering joint probabilities across multiple species; the ecological scale of management and conservation policies do not adequately consider area‐sensitive vulnerabilities of island communities as evidenced by the increasing risk of extirpation of island endemics whose populations have become isolated and reduced; old‐growth reserves are unlikely to maintain viable populations of endemic small mammals in isolation or as functionally connected metapopulations; and a spatially explicit analysis of individual home ranges demonstrated that forest‐wide standards and guidelines provide about half the breeding habitat needed by a federally listed endemic raptor, the Queen Charlotte goshawk (Accipiter gentilis laingi), of which only half of that is secure. Thus, assertions that the WCS is properly functioning as designed are dubious because a comprehensive monitoring plan has not been implemented and vital underlying assumptions are not supported by available science. We recommend 3 forest management and conservation policy adjustments: limit size and location old‐growth forest harvests, restore forests through intermediate stand management of second growth, and conduct a formal review of WCS elements and assumptions.

Estimation of the Aerial Biomass of Trees with Non-Conforming Trunks (Foothills) of the Forests of the Congolese Central Basin by the Method Non-Destructive: Case of the YASIKIA Forests (Opala/Tshopo Province/DRC)

Summary: It is important to estimate the aboveground biomass and carbon stocks of trees with non-conforming trunks in the forests of the central Congolese basin to plan resource management and to assess the contribution of these forests in mitigating the effects of climate change and, this within the framework of conservation at the scale of a reserve, that for Measuring, Reporting and Verifying forest carbon stocks within the framework of national strategies for the reduction of greenhouse gas emissions linked Deforestation and Forest Degradation (REDD+). This study aimed to set up a protocol for estimating the aerial biomass and the corresponding carbon stocks of trees with particular architecture in the Yasikia forest. To succeed, a dendrometric study was carried out for all trees with non-compliant trunks. Dendrometric data were collected on 189 trees divided into 9 families and 20 species. The results of this study show that it is preferable to use the equivalent diameter for a good estimate of the biomass because taking the diameter at the end of the buttress or above, underestimates the quantity of biomass for a tree with a trunk not compliant. The equation used to estimate the woody biomass from different diameters was that of Brown et al., (1989). The results of this study show that it is preferable to use the equivalent diameter for a good estimate of the biomass because taking the diameter at the end of the buttress or above, underestimates the quantity of biomass for a tree with a trunk not compliant.

Establishing Integrative Framework for Sustainable Reef Conservation in Karimunjawa National Park, Indonesia

The Coral Triangle region is facing negative impacts due to unbalanced carrying capacity and inappropriate public behavior, leading to unsustainable reef tourism. As a result, there has been increased awareness and preference for sustainable reef conservation (SRC). This study evaluates the integrative perspective framework of tourists’ heterogeneity preferences in SRC programs using a choice experiment conducted in Karimunjawa National Park (KNP), Indonesia. The study found that tourists preferred boat anchoring at the mooring buoy, a lower number of boats, smaller tourist groups with interpretation, added information boards, and environmental awareness education. Additionally, this research revealed that most tourists preferred the alternative SRC program and had a heterogeneous preference, which showed different features among each group. The scenario of an integrative program generated the highest value compared to the “recreational management” and “institutional control” scenarios. This evidence can assist policymakers in adapting policies for SRC programs and in potentially securing conservation funds associated with enhancing the institutional aspects of carrying capacity and marine environmental education for sustainable marine development.

Four conservation challenges and a synthesis.

Conservation and management of biological systems involves decision-making over time, with a generic goal of sustaining systems and their capacity to function in the future. We address four persistent and difficult conservation challenges: (1) prediction of future consequences of management, (2) uncertainty about the system's structure, (3) inability to observe ecological systems fully, and (4) nonstationary system dynamics. We describe these challenges in terms of dynamic systems subject to different sources of uncertainty, and we present a basic Markovian framework that can encompass approaches to all four challenges. Finding optimal conservation strategies for each challenge requires issue-specific structural features, including adaptations of state transition models, uncertainty metrics, valuation of accumulated returns, and solution methods. Strategy valuation exhibits not only some remarkable similarities among approaches but also some important operational differences. Technical linkages among the models highlight synergies in solution approaches, as well as possibilities for combining them in particular conservation problems. As methodology and computing software advance, such an integrated conservation framework offers the potential to improve conservation outcomes with strategies to allocate management resources efficiently and avoid negative consequences.

Statewide prioritization of vernal pools for pond-breeding amphibians in New Jersey

Vernal pools are required habitat of pond-breeding amphibians, yet their legal protections in the United States are not established, leaving vernal pools vulnerable to development and habitat fragmentation. Seasonally, amphibians migrate to breed in vernal pools. Roads and upland forest loss can jeopardize that migration, resulting in mortality. Vernal pools surrounded by fewer roads and more upland forest are of greater preservation priority in the management of amphibian populations. This study presents a statewide preservation prioritization of New Jersey's 13,594 vernal pools mapped in a previous work. The prioritization builds on that work by calculating a preservation score based on a combination of six characteristics regarding habitat fragmentation in the migratory area surrounding a vernal pool. The scores are calculated at a range of migration distances to account for a variety of amphibian species, and it is found that the different distances make little difference to preservation scores because of the overall small scale at which amphibians migrate. Results are presented that show clear parts of the state that should be prioritized for vernal pool preservation, mainly in areas where fewer roads lead to less development and habitat fragmentation. Areas of preservation priority are further refined using geographic clusters which show assemblages of vernal pools with favorable migratory areas. A special class of vernal pools has migratory areas that are uninterrupted by roads. These vernal pools and the assemblages of favorable migratory areas are often in preserved lands, but those that are not should receive special attention in both the field confirmation of amphibian habitat and subsequent protective measures, which can vary from conservation easements to citizen science interventions in sustaining local amphibian populations. Furthermore, surrounding states that also have a significant amount of vernal pools may be able to use this prioritization framework for preservation and conservation.

An Analytical Framework for Formulating Conservation and Development Measures for Important Agricultural Heritage Systems

Important Agricultural Heritage Systems (IAHS) are complex adaptive systems that are multidimensional and exhibit strategic values of sustainability. In the context of modernization, IAHS have been increasingly challenged. Thus, the heritage sites must explore dynamic conservation approaches and formulate adaptive management strategies. However, few studies have provided either theoretical methods or practical cases as support. In this study, we put forward an analytical framework for IAHS conservation and development measure formulation based on the Driver –Pressure–State–Impact–Response (DPSIR) model and applied it to the Shexian Dryland Stone Terraced System (SDSTS). With this framework, we analyzed the supportive mechanisms for the stable state of the SDSTS, diagnosed the threats and challenges it faces, and then formulated 34 conservation and development measures from six aspects, namely management mechanism construction, ecological conservation, cultural inheritance, green and organic product development, sustainable tourism development, and capacity building. It is demonstrated that the DPSIR-based analytical framework can provide both theoretical and technical support for the formulation of IAHS conservation and development measures, thus having the potential to become a general tool for the dynamic conservation and sustainable development of IAHS.

The benefits of big-team science for conservation: Lessons learned from trinational monarch butterfly collaborations

Many pressing conservation issues are complex problems caused by multiple social and environmental drivers; their resolution is aided by interdisciplinary teams of scientists, decision makers, and stakeholders working together. In these situations, how do we generate science to effectively guide conservation (resource management and policy) decisions? This paper describes elements of successful big-team science in conservation, as well as shortcomings and lessons learned, based on our work with the monarch butterfly (Danaus plexippus) in North America. We summarize literature on effective science teams, extracting information about elements of success, effective implementation approaches, and barriers or pitfalls. We then describe recent and ongoing conservation science for the monarch butterfly in North America. We focus primarily on the activities of the Monarch Conservation Science Partnership–an international collaboration of interdisciplinary scientists, policy experts and natural resource managers spanning government, non-governmental and academic institutions—which developed science to inform imperilment status, recovery options, and monitoring strategies. We couch these science efforts in the adaptative management framework of Strategic Habitat Conservation, the business model for conservation employed by the US Fish and Wildlife Service to inform decision-making needs identified by stakeholders from Canada, the United States, and Mexico. We conclude with elements critical to effective big-team conservation science, discuss why science teams focused on applied conservation problems are unique relative to science teams focusing on traditional or theoretical research, and list benefits of big team science in conservation.

Anatomy of spin-wave-driven magnetic texture motion via magnonic torques

The interplay between spin waves and magnetic texture represents the information exchange between the fast and slow dynamical parts of magnetic systems. Here we formulate a set of magnonic torques acting on background magnetic texture, by extracting time-invariant information from the fast precessing spin waves. Under the frame of magnonic torques, we use theoretical formulations and micromagnetic simulations to investigate the spin-wave-driven domain wall motion in two typical symmetry-breaking situations: the rotational symmetry broken by the Dzyaloshinskii-Moriya interaction and the translational symmetry broken by magnetic damping. The torque-based microscopic analyses provide compact yet quantitative tools to reinterpret the magnetic texture dynamics induced by spin waves, beyond the conventional framework of global momentum conservation.

Suitability Analysis of Water Cultural Heritage Structures in Beijing Based on Analytic Hierarchy Process and Geographic Information Systems

As significant physical carriers of hydraulic science and technology, water cultural heritage (WCH) structures might exert positive effects on the economy, society, and environment. However, it is challenging to develop a scientific conservation plan due to the lack of comprehensive cognition and value assessment criteria for the vast majority of WCH structures. In this study, the analytic hierarchy process (AHP) and geographic information systems (GIS) were introduced to develop a multidimensional evaluation system for WCH in Beijing based on the suitability perspective. This approach proposes a strategy covering macro, meso, and micro levels based on three aspects: heritage value, spatial distribution, and environmental resistance. The findings indicated that there are significant differences in values among the nine heritage categories, and royal gardens and rivers were suggested for greater emphasis on protection. Besides, the distribution of WCH structures is clustered, which can be categorized into four distinct agglomerative zones. Most of the heritage sites are found on built-up land with low elevation and gentle slopes, resulting in high environmental suitability. Lastly, we proposed a framework for conservation with “one centre, two wings, one area, and a multi-node” to facilitate the development of effective policies by decision-makers.

A review of bats of the genus Pseudoromicia (Chiroptera: Vespertilionidae) with the description of a new species

The Cameroon Volcanic Line, which divides the Congo Basin fauna from the West African fauna, is a known area of high endemism for various taxa, but the region’s bat fauna has received little attention. We review variation in morphological and molecular (mitochondrial Cytochrome b) characters in the Tropical African vespertilionid bat genus Pseudoromicia. Assessment of this variation indicates the existence of a new species of Pseudoromicia, from the Mbam Minkom Massif in the Centre Region of Cameroon. The new species is diagnosable by sequence data and is morphologically similar to its putative sister taxon, P. kityoi, from Uganda. Although we suggest that it be assigned to the IUCN category of Data Deficient, there should be some concern as to the conservation status of this species: the Mbam Minkom Massif ecosystem is threatened due to lack of legal conservation frameworks and exposure to increasing human pressure. The new species is in a clade with P. roseveari and P. kityoi. These three species may be relicts of a single widespread species originating in the West African “white-winged” group of Pseudoromicia that then spread east across the tropical moist broadleaf forest into East Africa, and are now restricted to a few upland rainforest patches in West Africa (P. roseveari), in outliers of the Cameroon Volcanic Line region (Pseudoromicia sp.), and the Lake Victoria area (P. kityoi). The smaller, white-winged species are hypothesized to be ancestral, with one extant putative species (P. rendalli) also extending into East and southern Africa (Van Cakenberghe & Happold, 2013). The larger, dark-winged taxa likely dispersed to East Africa and subsequently back to West Africa (e.g., Pseudoromicia sp., P. roseveari). Our data illustrate the potential importance of the Dahomey Gap and climatic changes in the evolution of this group of species. http://zoobank.org/urn:lsid:zoobank.org:pub:30929BAA-4043-422D-B209-16CAB826043E

Complete mitochondrial genome of the Spanish toothcarp, Aphanius iberus (Valenciennes, 1846) (Actinopterygii, Aphaniidae) and its phylogenetic position within the Cyprinodontiformes order

BackgroundThe Spanish toothcarp (Aphanius iberus Valenciennes, 1846) is a small fish endemic to the eastern coastline of the Iberian Peninsula and is currently listed as “Endangered” (category IUCN: EN). It mainly inhabits brackish waters which can exhibit large fluctuations in temperature and salinity throughout the year. The genetics of A. iberus are not well-known since most studies have only evaluated the genetic structure of the species under a conservation framework in order to identify its potential conservation units. Different phylogenetic relationships of Aphanius have been published based on some particular genes. In the present study, the entire mitochondrial genome of A. iberus was obtained for the first time in the context of an A. iberus reference genome and a hypothesis regarding its phylogenetic position was considered.Methods and resultsThe mitogenome (a circular doble-stranded DNA sequence of 16,708 bp) was reconstructed and aligned against 83 Cyprinodontiformes and two outgroup taxa to identify the phylogenetic position of A. iberus. PartitionFinder was first used to test for the best evolutionary model and the phylogenetic analyses were performed using two methods: Maximun-Likelihood Approximation (IQ-Tree) and Bayesian inference (MrBayes). Our results show that A. iberus forms a sister group with Orestias ascotanensis, a cyprinodontiform species native to South America.ConclusionsThe results were congruent with the traditional morphometric reconstructed trees and with a geological vicariant hypothesis involving Cyprinodontiformes where Aphaniidae is shown as a monophyletic family separated from the family Cyprinodontidae. The information gathered from this study is not only valuable for improving our understanding of the evolutionary history of A. iberus, but for future genomic studies involving the species.

Air Quality at Ponta Delgada City (Azores) Is Unaffected so Far by Growing Cruise Ship Transit in Recent Years

The ease of travel allowed by contemporary means of long-range transportation has brought increasingly higher numbers of visitors to remote and relatively undisturbed insular territories. In a framework of environmental conservation of the natural patrimony, sustainably accommodating touristic flooding and the associated polluting footprint poses a demanding challenge. Over the past decade, Ponta Delgada, the largest city of the mid-Atlantic Azores archipelago, has become a hotspot for transatlantic cruise ship (CS) lines in spring and autumn. CSs are substantial contributors to the emissions of greenhouse gases (GHG), as well as hazardous sulphur (SOx) and nitrogen (NOx) oxides. It is hereby retrospectively investigated whether the background levels of air pollutants were raised following the CS influx at Ponta Delgada, which conventionally displays great air quality. The daily CS traffic at the local harbor was associated with the daily concentrations of air pollutants (SO2, O3, NO2, NOx, PM10 and PM2.5), monitored by the local urban background monitoring station (~1.3 km northwards). Exceedances above daily legislated limits from 2013 until 2020 only occurred sporadically for PM10 and PM2.5, often during episodes of natural dust storms. No major correlation was found between CS parameters with the recorded values of pollutants, although a noticeable signal of NOX increase of southern origin is observed during spring days with CS presence. Daily data suggest CS influx has not strongly influenced background air quality. A near-source, real-time monitoring network should be implemented in the city to provide the necessary spatial and temporal resolution for tracking short-term fluctuations in air pollutants during CS arrivals and departures.

DIVERSITY OF LOCAL MAIZE IN EJIDOS OF THE FRAILESCA REGION OF CHIAPAS, MEXICO

<p><strong>Background</strong>: In studies of local maize diversity, conservation is often identified as a linear process, related to the limited analysis of the implications of technological change, especially improved commercial seed, on local maize potential and its conservation. This generates increasing socio-technical complexity <strong>Objective</strong>: To characterize the potential of local maize present in two ejidos of the Frailesca region of Chiapas, considering the farmers' knowledge about them and the configurations they adopt together with other maize in the context of technological change. <strong>Methodology</strong>: Using the snowball technique, peasant domestic production units that conserve local maize (LM) were identified and samples were collected. The ethnographic method was used to deepen the farmers' knowledge of the local varieties and the configurations they share with other maize. The characteristics of the ear and kernel of the collected LM were described. <strong>Results</strong>: In the selected peasant domestic production units farmers maintain 15 varieties of LM based on a broad knowledge of these varieties; the basis of the selection process, conservation and adaptation to the conditions where they preserve them. According to the parameters of grains and cobs the LM collected are concentrated in three groups and form non-linear configurations with improved maize and other local varieties, in correspondence with the homogenizing technological flow typical of the Frailesca region. I<strong>mplications</strong>: This productive environment where the conservation of LM is developed makes evident the importance of an integrative approach to capture their growing socio-technical complexity. <strong>Conclusions</strong>: The LM potential evidenced permanence and morphological variability despite the homogenizing effect of technological change in the study area, where the socio-technical framework of LM conservation becomes more complex and the broad expert knowledge of farmers on the management of maize diversity acquires greater relevance. </p>

Biocultural vulnerability exposes threats of culturally important species

There are growing calls for conservation frameworks that, rather than breaking the relations between people and other parts of nature, capture place-based relationships that have supported social-ecological systems over the long term. Biocultural approaches propose actions based on biological conservation priorities and cultural values aligned with local priorities, but mechanisms that allow their global uptake are missing. Wepropose a framework to globally assess the biocultural status of specific components of nature that matter to people and apply it to culturally important species (CIS). Drawing on a literature review and a survey, we identified 385 wild species, mostly plants, which are culturally important. CIS predominate among Indigenous peoples (57%) and ethnic groups (21%). CIS have a larger proportion of Data-Deficient species (41%) than the full set of International Union for Conservation of Nature (IUCN)species (12%), underscoring the disregard of cultural considerations in biological research. Combining information on CIS biological conservation status (IUCN threatened status) and cultural status (language vitality), we found that more CIS are culturally Vulnerable or Endangered than they are biologically and that there is a higher share of bioculturally Endangered or Vulnerable CIS than of either biologically or culturally Endangered CIS measured separately. Bioculturally Endangered or Vulnerable CIS are particularly predominant among Indigenous peoples, arguably because of the high levels of cultural loss among them. The deliberate connection between biological and cultural values, as developed in our "biocultural status" metric, provides an actionable way to guide decisions and operationalize global actions oriented to enhance place-based practices with demonstrated long-term sustainability.

Research on elastodynamic theory based on the framework of energy conservation

Based on the analysis of establishing dynamic equations by using Newton's mechanics, Lagrange's, and Hamilton's mechanics, a new idea of establishing elastodynamic equations under the framework of energy conservation is proposed. Firstly, Newton’s second law is used to derive wave equations of motion. Secondly, Lagrange's equation, Hamilton's canonical equations, and the corresponding dynamical equations in a continuum medium are derived by using Hamilton’s variational principle. Thirdly, under the framework of energy conservation, Lagrange's equation, Hamilton's canonical equations, and the acoustic dynamic equations of the continuum are established, and the results are proved to be consistent with those derived from classical mechanics. Some fuzzy understandings when using Hamilton's variational principle to establish Lagrange’s equation and Hamilton’s canonical equation, are clarified. A series of dynamical equations established under the framework of energy conservation provides an alternative way to characterize and represent the propagation characteristics of wave motions in various complex media without involving the variational principle of functional extremum. Finally, as an application example, the differential equation of elastodynamics in a viscoelastic medium is given under the framework of energy conservation.

A reimagined One Health framework for wildlife conservation

Abstract The One Health discourse is dominated by the role of animal health as a determinant of human health. This discourse often disregards the intrinsic and ecological value of healthy animals and is thus an inadequate framing for wildlife conservation. Our paper reimagines One Health for conservation purposes based on five premises: (i) health is cumulative; (ii) there are multiple species with different health needs and goals in the same setting; (iii) One Health emphasizes “bundled” relationships unique to a setting, rather than independent and intersecting spheres of health; and One Health should be (iv) equity informed and (v) have a shared goal that can be achieved through intersectoral actions. The reimagined framework is centered on the guiding principle that all actions should ensure no species or generation is prevented from reaching good health by the actions to protect other species or generations. Grounded in the positive outcome of health equity, the framework uses three prompts to guide One Health planning – populations, places and goals. The paper discusses how the framework can be applied for research concerning wood bison herds under imminent threat in Canada.

In the Name of Conservation

This thesis investigates the introduction, adaption, and implementation of the modern concept of heritage conservation in modern China after the opening of its treaty ports. Through an analysis of the different layers of disseminating and receiving knowledge in transnational exchanges, it explicitly points out the divergence between the Eurocentric concept of conservation and the Chinese tradition of treating historic buildings and sites. As a result of the complexity of understanding and adapting an imported idea, the heritage discourse in China is characterised by its own ambiguity. Conservation of modern heritage, in particular those built under colonial power, has seen conflicts of perceptions between conservation planning and interest-led practice. A progressive legislative framework for heritage conservation has had a limited binding effect on stakeholders’ actions to protect listed immovable built cultural heritage sites from artificial damage in China’s contemporary urban practices. By analysing various actors’ interpretations and expressions of the concept of “conservation” (known as “保护” in Chinese) derived from different temporalities, it explores the causes and effects of heritage strategies and approaches created by individuals, groups, and the state apparatus. Theoretically, it challenges the local acceptability of classic conservation principles that are primarily based on European thoughts and cultural background. Practically, it provides adequate clues for a multi-faceted consideration of listed heritage sites in future development. It highlights the significance of creating a powerful local narrative under the authoritative heritage discourse at a crossroads of ongoing globalisation and growing nationalism.
