This article presents an examination of research conducted on the flora and fauna of Yakutia, with a focus on key findings and outcomes. Throughout the past decades, new discoveries have been made regarding the diversity, distribution, biology, and ecology of the region’s plant and animal life, and an updated inventory of species has been conducted utilizing modern systematic principles and new scientific knowledge.
Zoological sciences widely rely on morphological data to reconstruct and understand body structures of animals. The best suitable methods like tomography allow for a direct representation of 3D-structures. In recent years, synchrotron radiation based x-ray microtomography (SR μCT) placed high resolutions to the disposal of morphologists. With the development of highly brilliant and collimated third generation synchrotron sources, phase contrast SR μCT became widely available. A number of scientific contributions stressed the superiority of phase contrast over absorption contrast. However, here we demonstrate the power of high density resolution methods based on absorption-contrast SRμCT for quantitative 3D-measurements of tissues and other delicate bio-structures in zoological sciences. We used beamline BW2 at DORIS III (DESY, Hamburg, Germany) to perform microtomography on tissue and mineral skeletons of marine sponges (Porifera) which were shock frozen and/or fixed in a glutamate osmium tetroxide solution, followed by critical point drying. High density resolution tomographic reconstructions allowed running quantitative 3D-image analyses in Matlab and ImageJ. By applying contrast and shape rule based algorithms we semi-automatically extracted and measured sponge body structures like mineral spicules, elements of the canal system or tissue structures. This lead to a better understanding of sponge biology: from skeleton functional morphology and internal water flow regimes to body contractility. Our high density resolution based quantitative approach can be applied to a wide variety of biological structures. However, two prerequisites apply: (1) maximum density resolution is necessary; (2) edge effects as seen for example in phase outline contrast SR μCT must not be present. As a consequence, to allow biological sciences to fully exploit the power of SR μCT further increase of density resolution in absorption contrast methods is desirable.

Traditionally, undergraduate science curricula include little or no "ethics," either as theory or practice. However, zoologists are currently enjoying considerable media exposure: some of it positive (as in conservation practice), but more often negative (pertaining to issues such as the use of animals for testing of drugs, and genetic engineering). More than ever before, zoologists are being asked to make value judgments, and many of these involve moral assessment; if we accept that zoologists (along with other scientists) are professionals, then we must accept that they are responsible for any decisions they make, and it then follows that they are accountable, which can have serious ramifications in cases of malpractice. Ethics involves the application of morality in a professional setting. In light of this, teaching ethics is mandatory in degree programs such as engineering and medicine. This paper contends that a key output of zoological education is the undergraduate who is cognizant of the ethical framework and constructs within which he/she must function. The paper concludes with comment on the nature and style of delivery of ethics education.

In many ways, science has never been as popular as it is now. With an ever-increasing number of popular science books on everything from astronomy to climate change and evolution and entire TV channels devoted to science output, the public seems spoilt for choice. However, paradoxically, there is also an increasing disconnect between science—and scientists—and society, and this is certainly evident in the life sciences. This disconnect comes in two forms: interest and level of knowledge. Indeed, one has only to look at the 2012 US presidential election campaign to see the lack of scientific knowledge possessed by many of the political elite about topics such as climate change. If high profile scientific topics are still so widely misunderstood by those in the public eye, it is unsurprising that there is such a lack of understanding of, and interest in, scientific topics in the general public. It should, in theory, be the easiest to address this discontent in subjects like zoology, where the evidence is all around us and can be easily seen, appreciated, and studied by the world’s citizens.
The catalog contains data on the archival collection of fishes of the family Zoarcidae stored in the Laboratory of Ichthyology, Zoological Institute, Russian Academy of Sciences. For each stored item, the following information is given: valid Latin name; other names under which the species could be recorded; specified data of the original label; and category of type material. Appendices include checklists of all stored type species, as well as genera and species currently absent in the archival collection of the Zoological Institute.

THE authors and editors of this book are scientists — disgruntled ones. They are dismayed at attacks on their science and science in general; attacks that come from outside scientific circles and from outside evidence and reason. The critics are widespread and include: those attending rallies where books are burnt, shock jocks who vilify the science of climate change, politicians who ignore the conclusions and recommendations of good science to see their name against another headline, and anonymous others who make death threats against climate researchers. The scientists involved in the production of this book are drawn predominately from zoological backgrounds — writing and communicating are not skills new to them. The book presents the ideas expressed in talks and posters put forward at a forum in 2008. These talks were subsequently written up, polished and peerreviewed before being published in November 2012. The book offers the thoughts and experiences of the authors relating to the book’s title Science under siege: zoology under threat. The forward tells us that the title was coined by Dr Paul Willis, Director of the Royal Institution of Australia (RiAus), yet he maintains he merely gave a name to a thought that evolved through the ruminations of others preparing the forum. The aim of the book is to mount a defence against the attackers, to communicate the real science and expose the shallowness of the attackers’ reasoning.

In the Eastern Aegean lies an island of forested hills and olive groves, with streams, marshes and a lagoon that nearly cuts the land in two. It was here, over two thousand years ago, that Aristotle came to work. Aristotle was the greatest philosopher of all time. Author of the Poetics, Politics and Metaphysics, his work looms over the history of Western thought. But he was also a biologist - the first. Aristotle explored the mysteries of the natural world. With the help of fishermen, hunters and farmers, he catalogued the animals in his world, dissected them, observed their behaviours and recorded how they lived, fed, and bred. In his great zoological treatise, Historia animalium, he described the mating habits of herons, the sexual incontinence of girls, the stomachs of snails, the sensitivity of sponges, the flippers of seals, the sounds of cicadas, the destructiveness of starfish, the dumbness of the deaf, the flatulence of elephants and the structure of the human heart. And then, in another dozen books, he explained it all. In The Lagoon, acclaimed biologist Armand Marie Leroi recovers Aristotle's science. He goes to Lesbos to see the creatures that Aristotle saw, where he saw them, and explores the Philosopher's deep ideas and inspired guesses - as well as the things that he got wildly wrong. Leroi shows how Aristotle's science is deeply intertwined with his philosophical system and how modern science even now bears the imprint of its inventor.
The International Commission on Zoological Nomenclature has voted in favour of a revised version of the amendment to the International Code of Zoological Nomenclature that was proposed in 2008. The purpose of the amendment is to expand and refine the methods of publication allowed by the Code, particularly in relation to electronic publication. The amendment establishes an Official Register of Zoological Nomenclature (with ZooBank as its online version), allows electronic publication after 2011 under certain conditions, and disallows publication on optical discs after 2012. The requirements for electronic publications are that the work be registered in ZooBank before it is published, that the work itself state the date of publication and contain evidence that registration has occurred, and that the ZooBank registration state both the name of an electronic archive intended to preserve the work and the ISSN or ISBN associated with the work. Registration of new scientific names and nomenclatural acts is not required. The Commission has confirmed that ZooBank is ready to handle the requirements of the amendment.
