Identifying species of birds by their songs is an important part of censusing, watching, and enjoying birds. However, differentiating among scores or hundreds of bird songs in an area can be difficult. Placing songs into a descriptive key can help in this endeavor by requiring the user to analyze each song and to identify similarities and differences among songs. In 2016, I published a bird song key to the Pipeline Road area in and adjacent to Soberanía National Park, Panama, which included 321 songs of 216 species. This key is, to my knowledge, the largest bird song key in the world. Since the key was published, two species—Rufous-breasted Wren (Pheugopedius rutilus) and Rufous-and-white Wren (Thryophilus rufalbus)—have moved into the area. This addendum adds three songs of Rufous-breasted Wren and three songs Rufous-and-white Wren to the key, thereby increasing the key’s song total to 327 and its species total to 218.

The uniqueness of human music relative to speech and animal song has been extensively debated, but never directly measured. To address this, we applied an automated scale analysis algorithm to a sample of 86 recordings of human music, human speech, and bird songs from around the world. We found that human music throughout the world uniquely emphasized scales with small-integer ratios, particularly a perfect 5th (3:2 ratio), while human speech and bird song showed no clear evidence of scale-like tuning. We speculate that the uniquely human tendency toward scales with small-integer ratios may have resulted from the evolution of synchronized group performance among humans.

Background: Identifying bird songs is an integral part of censusing, watching, and enjoying birds. However, doing so can be difficult due to the large variety of songs and, often, subtle differences among them. One way to facilitate this is to place songs into a descriptive key, thereby analyzing each song as well as identifying similarities and differences among songs. Objective: Here I present a key to bird songs in a bird-rich location in and adjacent to the Pipeline Road area, Soberanía National Park, Panama, to help researchers and birders in Panama identify and learn these songs, and, more importantly, to provide a model for a key to aid in the analysis and characterization of bird songs in other areas. Methods: After an unfruitful attempt to find a key I could use as a template, I developed an order of choices that groups similar songs, eliminates duplication, and optimizes the probability of correctly identifying them. The order is: trill or churr, slur (for songs that do not trill or churr), tempo, pitch, and other pertinent attributes. I followed a published system of descriptive units of bird songs (i.e., element, phrase, section) and gleaned from many sources how to describe various aspects of bird songs (e.g., pitch, quality, tempo). Definitions of terms and final choices are linked to recordings of songs available in www.xeno-canto.org. Results: This key includes 321 songs of 216 species in the intact rainforest along southern Pipeline Road and the fragmented forests and wetlands adjacent to the southern entrance to Pipeline Road. These songs include all but the most rarely heard songs of the area. Conclusion: This key is the first example of a descriptive key to bird songs in Central or South America, and is unique in at least the western hemisphere in its large scope, ordering of choices, and use of links to xeno-canto. It also provides a model for the construction of keys for bird songs in other areas. In addition, this work describes and utilizes many aspects of bird songs that, if employed, can improve your abilities to listen to, remember, and differentiate among songs.

The two main approaches to the use of the comparative method in legal research, functional and cultural, have some "predetermined" considerations regarding the results that will (or should) be discovered by comparing various legal phenomena — should the emphasis be on similarities or differences between these phenomena. These considerations are based on the vision of, respectively, the universal or pluralistic nature of law of various societies, and in fact they are able to correct substantially the process of cognition of legal phenomena using the comparative method, adjusting it to the desired result. In the case of similarities, we can talk about artificially narrowing the circle of countries under investigation. In the case of differences, the isolation of systems and the uniqueness of their cultural characteristics are unreasonably exaggerated. The alternative assumptions presented in the theory of comparative law regarding the existence of universal principles of law or the fundamental uniqueness of each legal system require a critical rethinking of constitutional provisions and practice in comparative studies. The use of the comparative method in constitutional law is not reducible to the implementation of the ideas of political philosophy, and objective conclusions should not be replaced by predetermined normative guidelines. The similarities and differences revealed by the researcher of constitutional ideas, norms and practices can be considered as a result of comparison of independent value.Constitutional law is associated with a variety of substantial constructs existing in the world, not excluding, however, their intercommunication. Understanding these constructions requires attention to both the similarities and the differences in specific legal orders (as well as the reasons for their functioning in this, and not another form). The use of the comparative method in the absence of striving for predetermined results is simultaneously aimed at understanding the laws of development of constitutional institutions and maintaining the horizon of their diversity as an important component of this development. Each time, the researcher should distance himself from his prejudices regarding the similarities or differences between the institutes under study, rechecking whether the obtained results are really the results of applying the comparative method, and not the initial constructions.The logic of a comparative study corresponds to the construction of theories of "middle level", aimed at forming the theoretical model of a particular legal in-stitution, taking into account the practice of implementing this institution in specific states. The focus on middle-level theories within the framework of the comparative method allows one to go beyond the description of single systems, formulate conclusions at the level of generalization that ensure the comparability of the studied objects, and at the same time maintain an understanding of the diversity of constitutional models.

Pilgerodendron uviferum (D. Don) Florin is an endemic, threatened conifer that grows in South America. In the sub-Antarctic territory, one of the most isolated places in the world, some forest patches remain untouched since the last glaciation. In this study, we analyze the tree structure and tree diversity and characterize the environmental conditions where P. uviferum-dominated stands develop within the Magellanic islands in Kawésqar National Park, Chile. An environmental matrix using the databases WorldClim and SoilGrids and local topography variables was used to identify the main environmental variables that explain the P. uviferum-dominated stands. PCA was used to reduce the environmental variables, and PERMANOVA and nMDS were used to evaluate differences among forest communities. The results show that two forest communities are present within the Magellanic islands. Both forest communities share the fact that they can persist over time due to the high water table that limits the competitive effect from other tree species less tolerant to high soil water table and organic matter. Our results contribute to knowledge of the species’ environmental preference and design conservation programs.

The current study aims to tackle the theoretical understanding of intention as between Sharia and law. It addresses the similarities and differences in the analysis of interpretation of intention across sharia law and law. The paper contrasts between the two ways of dealing with the concept of intention that is both technical and intuitive, across law and religion. Starting from the hypothesis that the concept of intention in sharia law originated in classical contextual realities different from the contemporary realities of Saudi Arabia and become outdated, the study attempts to answer the following questions: How can the concept of intention be adapted to the new socio-economic realities of Saudi Arabia with its new vision toward the world? How can the concept of intentionality adopt by sharia benefits from the analysis of law theory relating to intention? In order to answer the questions of the study, the study adopts the comparative law methodology through which concept of intention is comparatively examined in both sharia and law. The research investigates the historical and cultural context that gives rise to the concept of intentionality in both sharia law and law, as it helps reflect on aspects of similarity and differences and how gap between the sharia law and law can be bridged. The collected data is obtained through comparing sharia law in Saudi Arabia to the law applied in the West. The study has reached a conclusion that the sound methodological application of the concept of intention in sharia law requires the integration of elements and concepts from the Western law concept of intention.

<p><strong>Abstract.</strong> The Second Edition of the Atlas of Yellowstone will celebrate the 150-year history of the world’s first national park – and reflect on the future of Yellowstone and its evolving place in the world. Like the first Atlas of Yellowstone published in 2012, the Second Edition will provide a comprehensive view of the human and natural setting of Yellowstone National Park. Also like the First Edition, the new edition will portray variations over space and time, explore human-nature interactions throughout the region, document connections of Yellowstone to the rest of the world, and &amp;ndash; ultimately &amp;ndash; guide the reader to a deeper appreciation of Yellowstone.</p><p>Beyond that, the new edition will provide much expanded coverage of the park’s history. Readers will better understand the many different ways in which the creation of Yellowstone National Park has preserved and altered the landscapes and ecology of Yellowstone and conservation thought and practice, both locally and around the world.</p><p>The new atlas will also reflect advances in scientific data collection, knowledge, and insight gained since publication of the first edition. New topic pages will address key management issues ranging from increased visitor impact to wildlife disease to light pollution. In addition, many of the 850 existing graphics will be updated, reimagined, or replaced by new graphics that capture the remarkable wealth of data that has become available since the First Edition. Whether it be tracking of individual wolves, ecosystem imagery from space, or detailed visitor surveys &amp;ndash; new data provide insights that could not be graphically displayed before.</p><p>The Second Edition celebrates 150 years of America’s best idea and what that has meant to the world. The significance of Yellowstone National Park to conservation, scholarship, and the human experience is enormous, and deserves a volume that captures that importance.</p>

As trajetórias femininas na vida pública vêm ganhando cada vez mais espaço, com mulheres do mundo tomando as ruas como forma de luta e resistência. Na Argentina, dois exemplos emblemáticos servem como espelho para outros movimentos: as Madres de Plaza de Mayo e as feministas do Ni Una Menos. Criados em diferentes contextos sociais, faixas etárias e motivações políticas, estes grupos se tornaram estandartes da luta política e reivindicação a nível federal, e até mesmo global. Similaridades e diferenças entre os dois grupos devem ser observadas para entender de forma adequada suas constituições enquanto agentes sociais e políticos. Além disso, pretendemos perceber como essas mulheres, jovens e senhoras, transformaram a questão do feminino e do gênero em sinônimo de uma luta frente a uma sociedade patriarcal em todo o mundo.Palavras-chave: Gênero, Resistência, Ni Una Menos, Madres de Plaza de Mayo AbstractWomen's trajectories in public life have been gaining more and more space, with women of the world taking over the streets as a form of struggle and resistance. In Argentina, two emblematic examples serve as a mirror to other movements: the Madres de Plaza de Mayo and the feminists of Ni Una Menos. Built on different social contexts, age groups, and political grounds, have become banners of political struggle and claim at federal, and even global, level. Similarities and differences must be observed to properly understand their constitutions as social and political agents. In addition, we intend to understand how these women, young and old, have transformed the issue of the feminine and gender into a struggle that clashes with a worldwide patriarchal society.Keywords: Gender, Resistance, Ni Una Menos, Madres de Plaza de Mayo
