BMC Zoology considers articles on all aspects of zoological research. As the Journal aspires to be as broad as the subject discipline itself, we welcome submissions on all animals.

BMC Zoology is part of the BMC series, which publishes subject-specific journals focused on the needs of individual research communities across all areas of biology and medicine. We offer an efficient, fair and friendly peer review service and do not make editorial decisions on the basis of the interest of a study or its likely impact. Studies must be scientifically valid; for research articles this includes a scientifically sound research question, the use of suitable methods and analysis, and following community-agreed standards relevant to zoological research.

We are delighted to welcome Serge Morand, Brock Fenton, Thomas Flatt, Herbert Hoi and Laurence Packer as Section Editors for the Journal along with an expanding international team of Associate Editors [3]. Together with the in-house Editor, they will provide academic leadership and expertise. As the Journal grows and develops, we will continue to recruit academic editors to the Board in order to adapt to the changing and growing nature of the field.

BMC Zoology requires that experimental research on animals must comply with institutional, national, or international guidelines, and where available should have been approved by an appropriate ethics committee. The Basel Declaration [4] outlines fundamental principles to adhere to when conducting research on animals. Manuscripts that describe new taxa must follow the guidelines set by the International Commission on Zoological Nomenclature [5]. We require the new taxon name and the article it is published in to be registered with ZooBank [6].

BMC Zoology aims to publish work that, after a thorough peer review process by appropriate independent experts, is deemed to be a coherent and valid addition to the scientific knowledge. BMC Zoology will provide an open access platform to allow the effective dissemination of this knowledge, and to allow readers to explore and understand the most important developments, trends and practices in zoology. As the pioneering and original open access publisher, we believe that open access and the Creative Commons Attribution License [7] are essential in this, allowing universal and free access to all articles published in the Journal and allowing them to be read and the data re-used without any restrictions.

BMC Zoology will work closely with the rest of the journals in the BMC-series portfolio [8] to help authors find the right home for their research in the field of zoology. High impact submissions of outstanding merit will be brought to the attention of our flagship journal BMC Biology. We will highlight selected journal content through various marketing channels to ensure the research reaches its target audience and receives the attention it deserves.

The development of molecular tools and phylogenetic methods have contributed to the explosion of taxonomic and phylogenetic investigations. Parasite diversity appears considerable although often cryptic. In a parallel way, the studies of host–parasite interactions and parasitism have influenced many scientific disciplines from biogeography to evolutionary ecology by using various comparative methods based on phylogenetic information. Indeed, hosts and their parasites interact over both relatively long evolutionary and relatively short ecological time. Studies are still needed to investigate the co-diversification and co-interactions of hosts and their parasites in time and space [9].

Theoretical and empirical contributions on host-parasite (and host-symbiont) interactions are various from ecological immunity, to community ecology and health ecology. However, important questions remain regarding the host factors that may explain the diversity and diversification of parasites, and correlatively the effects of parasitism and symbiosis on the diversity and diversification of their hosts including the evolution of their life history traits.

The biotic interactions section of BMC Zoology welcomes submissions on comparative studies of host-parasite and host-symbiont interactions such as the analyses of co-adaptation taking into account history depicting by phylogenetics. Furthermore, BMC Zoology invites studies at the level of populations and communities that investigate biotic interactions in the context of biological invasion and biological conservation. There is a strong interest for publishing studies that investigate biotic interactions in the context of ecosystem regulating services and their implementation. Finally, we also welcome manuscripts that contribute to science-policy dialog for which the debate article type might be the ideal forum.

This general area of zoology covers a large spectrum both in terms of topics and endeavors across a huge variety of animals. For me, bats symbolize the diversity of, and connectivity among topics in this area, so I will explore them as an example.

Many of the ~800 species of insectivorous bats use echolocation to detect, track and identify their prey e.g., [10]. In a sense, these animals communicate with themselves, adjusting the design and timing of their echolocation signals to ensure that they obtain accurate information about their prey and the setting in which it is operating. The recent discovery [11] that a Japanese bat (Pipistrellus abramus) begins to track a second target while still closing on the first one is exciting because of the neuroscience and behavior that is involved. Neurobiology underlying echolocation has revealed the elegance, complexity, and accuracy of this form of behavior [10].

We also know that echolocating big brown bats (Eptesicus fuscus) use sensory hairs to collect information about air flow across their wing membranes [12]. Input from these hairs is fundamental to the maneuverability of flying bats. Still to be determined, however, is how most bats integrate information obtained by echolocation and by vision, because bats are not blind and some have acute eyesight. This is supported by work with Egyptian fruit bats (Rousettus aegyptiacus) which have a mental map of their home ranges [13].

On the other side of the coin, many species of insects, notoriously moths, lacewings, orthopterans, beetles and mantids, have bat detectors, ears allowing them to detect the echolocation calls of marauding bats e.g., [14]. Insects with bat-detecting ears are much less likely to be captured by hunting bats. Some species of tiger moths (Arctiidae) use acoustic displays as aposematic signals or to jam bats’ echolocation [15].

The vampire bat (Fig. 1) emerging from its day roost, adds thermal sensors [16] to its sensory array that includes vision, echolocation, acute hearing, and a high level of olfactory sensitivity. In vampire bats, individual recognition of group members is mediated by at least acoustic and olfactory cues [17]. Other bats also use echolocation calls of conspecifics to locate roosts and concentrations of prey.

Individual vampire bats can beg blood from familiar roost mates that may or may not be genetic relatives. This adds an additional layer of behavior and social interactions to the mix of cognition, sensory biology, signaling and communication. The possibilities are greatly enhanced by recurring evidence of bats learning foraging tasks and identification of prey by watching experienced conspecifics.

I chose bats as an example of the importance of cognition, sensory biology, signaling and communication in the lives of animals and in studies of zoology.

The cognition, sensory biology, signaling and communication section of BMC Zoology will particularly welcome manuscripts that present valid theoretical developments as well as rigorous empirical studies that draw together different aspects of cognition and sensory biology. Making connections to similar studies with other subject species will enhance the readership and impact of the articles. BMC Zoology is an ideal journal to present analyses drawing on large, long-term data sets. The online nature of the Journal makes it well suited to presenting large amounts of data.

Our planet is entering the 6^th mass extinction as a result of human impacts on all aspects of the world’s biota. Human survival depends upon the maintenance of biological diversity in ways that are often complex and poorly understood. Yet it is precisely this understanding that is required to permit conservation of as much of our remaining biological diversity as possible. Conservation research is a diverse field with numerous exciting new theoretical and methodological advances. However, none of these approaches will find successful practical application in the absence of the accurate monitoring of wildlife populations.

Through its conservation and wildlife monitoring section, BMC Zoology is interested in publishing scientifically valid research in all areas related to animal conservation and wildlife monitoring. The Journal considers the term wildlife to encompass all animal life. Of particular interest will be novel theoretical developments, rigorous empirical studies that illuminate conservation principles whether or not the target organisms are actively threatened, methodological advances that increase our ability to assess the status of wildlife populations and science-based commentary aimed at influencing policy makers. The Journal is also interested in publishing analyses that make use of the presentation of large, long term datasets. The online nature of the Journal is particularly suitable for the presentation of such large amounts of data.

The field of life history evolution seeks to explain how natural selection ‘designs’ organisms to achieve and optimize reproductive success under specific environmental conditions and given intrinsic organismal constraints [18–20]. Life history traits (e.g., age and size at maturity, number, size and sex ratio of offspring, age-specific schedules of fecundity and survival, lifespan) are the major phenotypic components of Darwinian fitness and thus direct targets of natural selection. Since natural selection can be defined as heritable variation in fitness components, understanding the causes and consequences of life history variation is of central importance for our understanding of adaptation [19, 20]. Life history traits are often connected to each other via constraining genetic, physiological and developmental relationships [21, 22]. Given these constraining relationships, the interactions among life history traits determine fitness. The study of life histories thus also illuminates our understanding of evolutionary trade-offs and constraints. Broadly defined, the field of life history evolution deals with all facets of life histories and fitness components, including evolutionary, ecological as well as mechanistic aspects [20, 22, 23].

The life history section of BMC Zoology is committed to publishing original research articles in all areas of animal life history including experimental, observational and descriptive studies, and covering the whole range of approaches, including evolutionary ecology, evolutionary demography, field observations, laboratory-based experimental approaches (e.g., phenotypic manipulations and assays, experimental evolution and artificial selection, breeding and quantitative genetic experiments), genetics and genomics, phylogenetics, physiology (including metabolism and endocrinology) and development. Subjects of particular interest also include the evolution and proximate mechanisms of life history plasticity, trade-offs, and constraints, as well as the evolution of life cycles.

In order to understand the physiological functions, adaptions or correlations of animals, we are studying the structure and functionality of subcellular compartments e.g. nuclei, mitochondria, chloroplasts or even smaller cellular parts. To fully understand and characterize an animal, one must also look at the structures and functions of cells, tissues, organs, organisms, habitats and behavioral patterns.

Both disciplines, comparative physiology and morphology, are multi- and interdisciplinary fields. To study them together means understanding evolution, ecosystems, environmental changes and circumstances and analyzing behavior. Looking into how cells, organs and organisms communicate by understanding the informational flow within and between cells, tissues, organs and organisms is a key part. A major research topic in animal physiology, summarizing all its sub disciplines remains the question on how homeostasis is achieved. Homeostasis means to keep you comfortable and constant which for animals mean the ability to explore new ‘worlds’ and ‘niches’.

The last centuries provided fundamental insights and this was achieved by methods sometimes considered old-fashioned and simple. But these methods are still indispensable, valuable and precise providing us with fundamental insights. We now complement these findings, theories and rules by new, modern and exciting methods and possibilities to strengthen and deepen our knowledge. Next generation sequencing (NGS), life-imaging, 4D-fluorescence microscopy, high resolution light microscopy, laser scan microscopy (LSM), single cell analyses and measurements among others are examples of tools and techniques that will provide new insights and possibilities.

Modern zoologists will be able to combine the scientific results coming from different levels of organizations (i.e. population studies, organismal and cellular studies) and integrate it into a whole entity in our field, the integrative and modern disciplines of comparative physiology and morphology.

The comparative physiology and morphology section of BMC Zoology welcomes submissions with a focus on comparative studies at different levels as they exist between different species, populations, individuals, organs, tissues or cells within species. We particularly welcome manuscripts which focus on the special needs of specific organisms providing hints on their evolutionary relationship or convergent evolutionary background.

The first and most sensitive response of an organism to changes in its environment are behavioral changes. Environment and climate change, reduction and fragmentation of habitats and the loss of resources; investigations on how animals adapt to new conditions is timely and important.

We can imagine that children who consume large amounts of unhealthy food and grow up without forming social bonds through the interaction with other children may display unwanted behavioral traits as adults. In non-human animals, increasing or decreasing population densities, rapid changes in physical and social environments, human disturbance and rapid changes in their parasite community or disease risk have an impact on behavior. Behavioral studies are therefore an important area of zoological research.

The sociobiology, parental and sexual behavior section of BMC Zoology welcomes manuscripts about the social, sexual or reproductive behavior of animals. Studies can be correlative, experimental, methodological or theoretical. We are particularly interested in research that focuses on the influence of environmental impact on behavioral patterns but also on the genetic background influencing behavioral adaptation and plasticity. BMC Zoology further invites manuscripts describing mechanistic research on personality or behavioral organization of animal systems including complex statistical approaches such as social network analyses.

Systematics is the branch of biology that deals with classification and nomenclature. Biogeography seeks to understand the patterns of distribution of taxa over space and time. Both incorporate phylogenetic analysis to form the basis for our comprehension of all aspects of our planet’s biological diversity. There has been an increase in the diversity of tools available for the study of both systematics and biogeography: including both means of data acquisition and analysis. The identification and description of existing species as well as the georeferencing of their locality data are particularly important in comparatively underexplored regions of the world. However, the use of new integrative studies in the analysis of species’ distribution and diversity is also generating important new insights in well studied faunas.

The systematics and biogeography section in BMC Zoology embraces studies related to the description of new zoological taxa and their phylogenetic interrelationships and biogeographic histories at all levels. Articles incorporating any rigorously applied methods are welcome. These may range from simple new species descriptions to new phylogeny-based classifications; or they may deal with the impact of newly explored characters on our understanding of the evolution and distribution of any taxonomic group of animals. The online nature of the Journal provides the possibility of publishing very long, copiously illustrated papers should be particularly attractive to those wishing to publish thorough taxonomic revisions, extensive molecular taxonomic treatments, or the results of large scale biogeographic analyses.
