Abstract:
ABSTRACT: Louis Fraser, sometime curator of the museum of the Zoological Society of London, was described by his contemporaries as a protégé of the 13th Earl of Derby, an “excellent naturalist”, a “zoological traveller” and the author and publisher of Zoologica typica. Published sources provide some information about Fraser but it is not entirely supported by papers in the Public Record Office, Kew, by the minutes of the council meetings of the Zoological Society of London and by Lord Derby's correspondence held at Liverpool and Philadelphia. Fraser corresponded with Lord Derby for eleven years between 1840 and 1851 and his letters to Lord Derby, together with other archives, provide a more accurate and detailed account of this eventful decade of his life, which included his experiences as zoologist on the 1841 naval expedition to the River Niger and his visit to Tunisia in 1846 collecting for Lord Derby about which, hitherto, little has been written.

Abstract:
The State Zoological Museum and the Establishment of the Polish Academy of Sciences: The Beginnings of the Institute of Zoology of the Polish Academy of Sciences The State Zoological Museum, established in 1928, inherited and developed the legacy of the Zoological Cabinet of the University of Warsaw (existing since 1818). The Cabinet’s collection had been gathered for decades and belonged to eminent personages not only in Poland but also in Europe. The Museum and its collections were threatened many times: first by a great fire in 1935, then by the German attack on Warsaw in 1939 and subsequent occupation, as well as by the outbreak of the Warsaw Uprising and the destruction of the city. After the post-war reconstruction of the Museum, it was time to function in a new political reality, in which the most significant change for this institution was the establishment of the Polish Academy of Sciences. A planned inclusion of the State Zoological Museum in the structures of the newly-founded Polish Academy of Sciences meant that the scientists had to face a dilemma: in exchange for research funds and career development opportunities, they were expected to show favour to the communists and readiness to implement the idea of socialism. In the background of this process, numerous scientific conferences took place, where controversial visions of the future of biological sciences clashed. This process resulted in the transformation of the State Zoological Museum into the Institute of Zoology of the Polish Academy of Sciences.

Abstract:
This paper considers some aspects of the history of the Zoological Museum and the Zoological Institute of the Academy of Sciences of the USSR, which appeared on its base in 1931, during two decades following the outbreak of the First World War. It deals with the scientific, social and political consequences caused for the Zoological Museum by the First World War, two Revolutions of 1917 and subsequent Civil War. The paper describes establishment of the Museum’s Council, which ruled from 1917 to 1930, and an attempt to evacuate collections in 1917, as well as conditions under which the Museum zoologists had to work in the period of the wars and revolutions. The first years of the restoration of normal work of the Zoological Museum after the Civil War are considered, as well as the effects of the flood, which damaged the Ichthyological, Herpetological and Osteological departments of the Museum in 1924. The renaming of the Museum into the Institute during the reform of the Academy of Sciences in 1929–1934 is discussed as well as layoffs and repressions during this reform. The paper considers changes in the Exhibition Department, made on demand of the authorities. The information is given about the Faunistic Conference of 1932, which was hosted by the Zoological Institute of the Academy of Sciences of the USSR under the slogan for “the Party’s” and “Bolshevik’s faunistic studies”.

Abstract:
While Secretary of the Zoological Society of London (1935–42), Julian Huxley used that institution to undertake several types of reform related to his promotion of ‘general biology’. Huxley's goal was to place synthetic, analytical and explanatory work at the centre of the life sciences. Here, zoological specifics served only as instances of generic processes. Huxley's campaigning fitted both into his own lifelong obsession with synoptic views and into much larger transformations in the epistemic culture of the life sciences during the interwar years. However, such campaigns also had their detractors, and the Zoological Society of London provides a superb example of the backlash provoked against these reforms. In 1942 that backlash led directly to Huxley's dismissal as Secretary of that society. This episode serves as a reminder to understand the plurality of views in play during any historical period. In this case, general biology was resisted in a factional dispute over what should be the priority of the life sciences: objects versus processes, induction versus explanation, and particulars versus generics.

Abstract:
The most important zoological collection in London outside of the British Museum was that established by the Zoological Society of London. It was to have only a fleeting existence of 30 years from its foundation in 1825. Yet in that short space of time, its collections of vertebrate specimens came to rival those of the British Museum both in volume and in taxonomic value, and attracted visiting workers from Europe to study its specimens. To some extent its extraordinary success was due to the high calibre of its contributors during the expansionist and exploratory period of the British Empire, but the quality of its curatorial staff played an important role in its success. Well within the three decades of its lifespan inadequate funding leading to difficulties with accommodation and insufficient spending on the care of the specimens caused the collection to deteriorate. Within the administrative priorities of the Society the Museum took second place to the Menagerie and by 1854 the dispersal of the collection had commenced. Some of the material came to the British Museum but not all the important specimens. Many specimens including type material and historically important collections were dispersed to relatively obscure local collections in which their importance has been lost sight of, if it was ever recognized. This paper outlines the history of the Zoological Society's Museum, discusses the importance of its holdings and assesses the contribution that it made to the collections of the British Museum.

Abstract:
American zoological parks have been sites of intense consumer and scholar interest since their origination in the 20th century. Today, zoos reside at a tenacious hub of ideologies, practices, and priorities contributed to by various stakeholder groups. I propose that the foundational cause of this tension is zoological multiplicity: the theory that through human practices and perceptions, animals can embody multiple identities. Via an exploration of zoological multiplicity in American zoos with specific focus on zoo management, zoogoer, and animal activist stakeholder groups, this project proposes the widespread acknowledgment and understanding of zoological multiplicity as a method to improve animal care and global wildlife conservation projects.

Abstract:
Zoo officials have for many years participated in ex situ conservation activities. Recently however, a growing number of zoos have shown an interest in becoming involved with in situ conservation projects. One such zoo is the North Carolina Zoological Park (NCZP) in Asheboro, NC. NCZP officials have committed to several of these projects and are aware of their importance. However, little is known about how visitors regard these activities. The two research questions asked were: 1) Are visitors aware of the NCZPâs involvement in in situ conservation efforts? and 2) Do patronsâ of the NCZP support those efforts? Three hypotheses were identified. These included: H1: visitors with an increased awareness of the zooâs involvement in in situ conservation would provide a greater amount of support for these projects, H2: membership status would not affect a visitorâs level of declared support for in situ conservation, and H3: membership status would affect a visitorâs level of monetary support for in situ conservation. A survey instrument was developed using a cross-sectional design. The survey focused on four key elements including contributions (monetary support), declared support for local and international projects, understanding of in situ conservation, and visitor relationships with the zoo. The survey was conducted on-site at the NCZP in June and July 2007. Tests of statistical significance and measures of association indicated that awareness played a statistically significant role in how much declared support a visitor had for a project, but had little to no role in how much money visitors contributed on an annual basis. Findings also indicated that membership status was not related to declared support and therefore this relationship was not statistically significant. Finally findings indicated that the relationship between membership status and annual monetary contributions was statistically significant. Recommendations for the NCZP were made based on the studyâs findings.

Abstract:
Silks are biomaterials made by spiders and silkworms, evolved for natural functions ranging from protection to predation. The research presented in this Thesis combines principles and methods from engineering, physics and biology to study the material properties of single silk fibres from a biological perspective. In particular, the factors that contribute to the variation in properties of single silk fibres are investigated. The first part of the Thesis focuses on silks made by silkworms. Whether naturally spun or forced reeled, the mechanical properties of these silks are sensitive to a range of environmental and processing conditions, such as humidity, stretching and reeling speed. The research presented in this section contributes to the understanding of how these applied conditions affect silk mechanical properties, which can be understood in terms of silk’s protein structure and biological context. The second section compares both silkworm and spider silk single fibres to other materials in terms of their sonic properties – how the materials propagate sound waves, whether following impact, or propagating vibrations. The results are discussed in the context of the silk’s natural function for impact resistance (silkworm cocoon or spider web) and vibrational signalling (spider silks). The Thesis ends with a discussion of how the presented techniques can be applied to help further our understanding of orb web function through studying spider silks. Overall, this interdisciplinary Thesis contributes to our understanding of the structure-property-function links of these fascinating biomaterials.

Abstract:
Sex chromosomes experience distinct evolutionary environments, due to their unusual pattern of inheritance, and studies of sex chromosome evolution can shed light on the fundamental evolutionary forces acting across the genome as a whole. Here, I combine genomic and transcriptomic data across a wide range of avian species to explore the evolutionary processes governing sex chromosome evolution. Birds are female heterogametic and therefore it is possible, via comparisons with male heterogametic species, to identify the fundamental factors driving sex chromosome evolution, versus those associated with sex. In this thesis, I uncover a complex mosaic of recombination suppression between the Z and W chromosomes, characterized by repeated and independent divergence of gametologs, together with ongoing genetic exchange. Additionally, I highlight the role of mating system, and interplay between evolutionary forces, in driving coding and expression evolution on the Z and W chromosomes. My findings indicate that although the Z chromosome is masculinized for male-specific effects, the magnitude of genetic drift acting on Z-linked genes is elevated in promiscuous relative to monogamous mating systems. In contrast, evolution of the female-limited W chromosome is governed predominately by purifying selection. Together, my results suggest that the role of the Z chromosome in encoding sexual dimorphisms may be limited, but that W-linked genes play a significant role in female-specific fitness. In conclusion, my findings reveal the power of mating system in shaping broad patterns of genome evolution.

Abstract:
Der Streifenkiwi (Apteryx mantelli) kommt im Freiland nur auf der Nordinsel Neuseelands vor. Aufgrund des gefährdeten Bestands ist eine sich selbst erhaltene Zoopopulation wichtig. Kenntnisse des Verhaltens helfen, die Ansprüche der Tiere zu verstehen. Zudem können sie darüber Auskunft geben, inwiefern das Wohlbefinden eines Tieres gegeben ist. Durch die Untersuchung der Brutaktivität sollte ein Überblick über den allgemeinen Verlauf der Brut gegeben und Aktivitätsmuster für den Berliner Hahn erarbeitet werden, um den Verlauf zukünftiger Bruten einschätzen und eventuell positiv beeinflussen zu können. Dazu kamen die Untersuchung der täglichen Aktivität einer Henne sowie Beobachtungen des Verhaltens der Tiere. Diese dienten der Bestandsaufnahme der gezeigten Verhaltensweisen und sollten zusammen mit der Aktivität die Grundlage zur Einschätzung bilden, ob die Ansprüche der Kiwis im Zoo Berlin erfüllt werden, und Hinweise zur Verbesserung der Haltung geben. Die Brutaktivität des Hahnes konnte über drei Brutperioden hinweg detailliert dargestellt werden und zeigte, dass nicht nur innerhalb der Art sondern bei einem einzigen Tier unter ähnlichen Bedingungen die Variabilität so groß sein kann, dass sie für Vorhersagen über den Erfolg einer Brut nicht geeignet ist. Im Zusammenhang mit der Aktivität der Henne ließen sich keine Auffälligkeiten erkennen, die auf eine allgemeine Störung der Tiere schließen lassen oder für eine Beeinträchtigung der Brut verantwortlich gemacht werden könnten. Soweit aus den Beobachtungen im Freiland geschlossen werden kann, scheinen die Kiwis im Zoo ein weitgehend natürliches Verhalten zu zeigen. Die Haltungsbedingungen scheinen den Ansprüchen der Tiere zu entsprechen. Es ließen sich nur bedingt Strategien entwickeln, um die Bedingungen für die Brut und damit für die Nachzucht zu verbessern, da sich die Aktivität des Hahnes während der Brut von Jahr zu Jahr als unerwartet variabel erwies. Für ein weiteres Verständnis des Brutverhaltens und eine mögliche Verbesserung der Bedingungen wäre eine Untersuchung zum Einfluss verschiedener Umweltfaktoren auf die Brutaktivität des Hahnes wünschenswert.
The North Island brown kiwi (Apteryx mantelli) is an endemic inhabitant of New Zealand's North Island. A self-preserving population at the zoos is important because of endangerment in the wild. Knowledge about their behaviour can help to understand the animal's requirements. Additionally it can provide information on the extent to which their well-being is given in captivity. Observing the breeding activity should lead to an overview of the brood's characteristics and the male's activity pattern in order to assess future broods and possibly influence them in a positive way. Additional observations about the female's daily activity and the male's and female's behaviour were conducted. This led to an inventory of their behavioural patterns. Together with the activity data, this provided a basis for assessing the well-being of the kiwis at Berlin Zoo and to optimize the keeping conditions. The male's breeding activity was described in detail for three breeding periods. It was shown that the variability was very high under similar conditions, so predictions about the breeding success were feasible. In conjunction with the female's activity there were no indications implying an overall disturbance negatively influencing the animals or their breeding. As far as it is known from observations in the wild, kiwis at the zoo seem to widely display natural behavioural patterns. The keeping conditions appear to meet the animal's demands. There were only few strategies that could be developed for further optimization of the breeding conditions because of the high variability of the male's activity. For a deeper understanding of the breeding behaviour and possible improvement of the breeding and keeping conditions, additional research about the activity's dependency on environmental factors would be desirable.

Abstract:
This thesis focuses on conflict resolution and collective decision-making in co-navigating pigeons, Columba livia. These birds have a remarkable homing ability and frequently fly in flocks. Group navigation demands that group members reach consensus on which path to follow, but the mechanisms by which they do so remain largely unexplored. Pigeons are particularly suitable for studying these mechanisms, due to their sociality and the fact that their possession of information can easily be altered and quantified. I present the results of a series of experiments that manipulated the experience of homing pigeons in various ways so as to observe the effect of information they had previously gathered on their group behaviour. Key findings were: Previous navigational experience contributes to the establishment of leader-follower relationships. The larger the difference in experience between two co-navigating pigeons, the higher the likelihood the more experienced bird will emerge as leader. Shared homing experience through repeated joint flights can allow two pigeons to develop into a “behavioural unit”. They form spatial sub-groups when flying with less familiar birds, and perform a similar transition between compromise- and leadership-dominated flights as single birds, although they are more likely to accept compromise routes. Such previous association histories between birds can thus affect collective decision-making in larger flocks. There is a trade-off between the amount of spatial information handled and the efficiency with which such information can be applied during homing. Leading/following behaviour is influenced by the recency of the route memories. Leadership hierarchies in pigeon flocks appear resistant to changes in the navigational knowledge of a subset of their members, at least when these changes are relatively small in magnitude. The stability of the hierarchical structure might be beneficial during decision-making. Mathematical modelling suggests that underlying hierarchical social structures can increase navigational accuracy. Hierarchically organised groups with the smallest number of strong connections achieve highest accuracy. Group leader-follower dynamics resemble the underlying social structure.

Full text
Abstract:
Die nichtproteinogene Aminosäure GABA (γ-Aminobuttersäure) gilt als der wichtigste inhibitorische Neurotransmitter im Zentralnervensystem von Vertebraten sowie Invertebraten und vermittelt ihre Wirkung u. a. über die metabotropen GABAB-Rezeptoren. Bisher sind diese Rezeptoren bei Insekten nur rudimentär untersucht. Für die Amerikanische Großschabe als etablierter Modellorganismus konnte pharmakologisch eine modulatorische Rolle der GABAB-Rezeptoren bei der Bildung von Primärspeichel nachgewiesen werden. Ziel dieser Arbeit war eine umfassende Charakterisierung der GABAB-Rezeptor-Subtypen 1 und 2 von Periplaneta americana. Unter Verwendung verschiedenster Klonierungsstrategien sowie der Kooperationsmöglichkeit mit der Arbeitsgruppe von Prof. Dr. T. Miura (Hokkaido, Japan) in Hinsicht auf eine dort etablierte P. americana EST-Datenbank gelang die Klonierung von zwei Rezeptor-cDNAs. Die Analyse der abgeleiteten Aminosäuresequenzen auf GB-spezifische Domänen und konservierte Aminosäure-Reste, sowie der Vergleich zu bekannten GB Sequenzen anderer Arten legen nahe, dass es sich bei den isolierten Sequenzen um die GABAB-Rezeptor-Subtypen 1 und 2 (PeaGB1 und PeaGB2) handelt. Für die funktionelle und pharmakologische Charakterisierung des Heteromers aus PeaGB1 und PeaGB2 wurden Expressionskonstrukte für die Transfektion in HEK-flpTM-Zellen hergestellt. Das Heteromer aus PeaGB1 und PeaGB2 hemmt bei steigenden GABA-Konzentrationen die cAMP-Produktion. Die Substanzen SKF97541 und 3-APPA konnten als Agonisten identifiziert werden. CGP55845 und CGP54626 wirken als vollwertige Antagonisten. Das in vitro ermittelte pharmakologische Profil im Vergleich zur Pharmakologie an der isolierten Drüse bestätigt, dass die GABA-Wirkung in der Speicheldrüse tatsächlich von GBs vermittelt wird. Für die immunhistochemische Charakterisierung konnte ein spezifischer polyklonaler Antikörper gegen die extrazelluläre Schleife 2 des PeaGB1 generiert werden. Ein weiterer Antikörper, welcher gegen den PeaGB2 gerichtet ist, erwies sich hingegen nicht als ausreichend spezifisch. Western-Blot-Analysen bestätigen das Vorkommen beider Subtypen im Zentralnervensystem von P. americana. Zudem wird der PeaGB1 in der Speicheldrüse und in den Geschlechtsdrüsen der Schabenmännchen exprimiert. Immunhistochemische Analysen zeigen eine PeaGB1-ähnliche Markierung in den GABAergen Fasern der Speicheldrüse auf. Demnach fungiert der PeaGB1 hier als Autorezeptor. Weiterhin konnte eine PeaGB1-ähnliche Markierung in nahezu allen Gehirnneuropilen festgestellt werden. Auch die akzessorischen Drüsen der Männchen, Pilzdrüse und Phallusdrüse, sind PeaGB1-immunreaktiv.
The non-proteinogenic amino acid GABA (γ-aminobutyric acid) is the major inhibitory neurotransmitter in the central nervous system of vertebrates and invertebrates, and GABA mediates its action among others via metabotropic GABAB receptors (GBs). So far, these receptors are only rudimentary characterized in insects. In the American Cockroach, which is an established model organism, pharmacological studies have pointed out a modulatory role of GBs in the production of primary saliva in the salivary gland. Therefore, the aim of this study is the profound characterization of the GABAB receptor subtypes 1 and 2 of Periplaneta americana. Diverse cloning strategies and the access to a Periplaneta EST-database enabled the cloning of two receptor-cDNAs. The analysis of the deduced amino acid sequences for GB-specific domains and conserved amino acid-residues, and the comparison to known GB-sequences of other species revealed that the sequences correspond to GABAB receptor subtypes 1 and 2 (PeaGB1 and PeaGB2). Next, we functionally and pharmacologically characterized the receptor-heteromer of PeaGB1 and PeaGB2. Therefore, we established expression constructs for the transfection of HEK-flpTM-cells. The PeaGB1/PeaGB2 heteromer inhibits dose-dependently the production of cAMP. The substances SKF97541 and 3-APPA imitate the GABA effect. In contrast, CGP54626 and CGP55845 are considered to be proper antagonists. The comparison of the in vitro with the known pharmacology of isolated glands reveals that GBs indeed mediate the effect of GABA in the salivary gland. For immunohistochemical localization, a specific polyclonal antibody was raised against the extracellular loop 2 of PeaGB1. A second antibody, which was raised against the analogous region of the PeaGB2, must be considered to be non-specific. Western blot analyses demonstrate the localization of both subtypes in the central nervous system of P. americana. Additionally, PeaGB1 is expressed in the salivary gland and in male accessory glands. Immunohistochemical analyses reveal the expression of PeaGB1 in GABAergic nerve fibers of the salivary gland. As a consequence, PeaGB1 must act as an autoreceptor in this organ. A widespread distribution of PeaGB1 in almost all neuropiles was detected in the cockroach brain. In the male accessory glands mushroom gland and phallic (conglobate) gland, an intense PeaGB1-like immunoreactivity was measured.

Abstract:
The trophy hunting of African leopards Panthera pardus pardus may generate revenue to help foster their conservation. However, leopards are sensitive to hunting and populations decline if overharvested. The practice therefore requires careful management grounded in robust estimates of population density/status. Camera-trap surveys are commonly used to establish leopard numbers, and may guide harvest quotas. However, such surveys are limited over wide spatial scales and many African governments lack resources to implement them. In this thesis I explore the potential use of a harvest composition scheme applied to puma Puma concolor in North America, to monitor leopards. The method hinges on the susceptibility of different leopard cohorts to hunting and if this varies, then predictions can be made about harvest composition. Susceptibility is likely to be governed by space use, encounter rates with bait lures (a common method used to attract leopards to hunting hides) and hunter selectivity. Thus in this thesis I explore leopard susceptibility to these factors using a protected leopard population in northern Zululand, South Africa. In my first chapter I examine using scent lures in camera-trapping. Against a backdrop of a passive survey I show adult males, females and sub-adults are captured at similar rates compared to a passive survey using lures. The use of lures does not appear to violate closure assumptions or affect spatio-temporal patterning, but their use appears limited as density estimate precision is not improved. My second chapter examines ecological (likelihood of encountering a hunter) and anthropogenic (attractiveness to hunters) susceptibility of leopards to trophy hunting. I show that adult males are the most susceptible cohort to hunting (sub-adults least susceptible). I then take the incident rates from ecological and anthropogenic models and create a theoretical harvest composition using population parameters of protected leopards. My third data chapter departs from hunting susceptibility and examines determinants of leopard trophy package price across Africa. I show that factors such as trophy quality, outfitter leopard hunting reputation and hunt success have little impact on price determination. Instead, overall outfitter reputation and the number of charismatic species in a package are positively correlated with price. These results have important consequences on several sustainable leopard hunting schemes proposed in the literature.

Abstract:
Streptococcus pneumoniae (the pneumococcus) is a bacterial pathogen responsible for >1.6 million annual deaths globally. Pneumococcal penicillin-resistance is conferred by acquisition of ‘altered’ penicillin-binding protein (pbp) genes. The first penicillin-nonsusceptible pneumococci were identified in the late 1960s. Global pneumococcal penicillin-nonsusceptibility rates rapidly increased in the 1980s/90s. Since 2000, protein-conjugate vaccines, targeting 7, 10 or 13 of the ≥94 different pneumococcal capsule types (serotypes), have been introduced in many countries. Following vaccine implementation there has been a decline in vaccine-type pneumococcal disease and an increase in non-vaccine-type disease. These epidemiological changes result from “serotype replacement” and/or “serotype switching”. The former describes the expansion of non-vaccine-type clones in the absence of vaccine-type pneumococci. The latter describes serotype change following recombination at the capsule polysaccharide synthesis (cps) locus. To fully understand how pneumococci respond to vaccine- and antibiotic-induced selective pressures, we must better understand the evolutionary history of this pathogen. This thesis describes the study of a global collection of 426 pneumococci, dated 1937 - 2007. Serotype, genotype and penicillin-susceptibility data were collected. Nucleotide sequences of three pbp genes (for 389 isolates) and whole-genome sequences (for 96 isolates) were also generated. The data demonstrated the long-term persistence of certain clones within pneumococcal populations, and that pbp and large-fragment (>30 kb) cps ± pbp recombination was occurring prior to both widespread antibiotic use and vaccine implementation. The data highlighted the promiscuous nature of the globally-distributed PMEN1 clone and its contribution to the spread of pneumococcal penicillin-resistance. PMEN1 also donated multiple, large regions (1.7 - 32.3 kb) of its genome to at least two un-related clones. Finally, six “Tn916-like” genetic elements, conferring resistance to non-penicillin antibiotics, were newly identified. These included two of the oldest ever described. These results provided a unique insight into the history of pneumococcal evolution and the importance of genetic recombination.

Abstract:
Aristotle’s first period in Athens had lasted for twenty years. In 347 he suddenly left, probably for political reasons. During his travels, 347–35, he undertook most of the work on which his scientific reputation rests. He made or collected observations in astronomy, meteorology, chemistry, physics, psychology, and other sciences; but his scientific fame rests primarily on his work in zoology and biology. According to ‘Zoological researches’, his studies on animals laid the foundations of the biological sciences and were not superseded for over two millennia. His History of Animals is not flawless, but it is a masterpiece. Nowhere else does Aristotle show more vividly his ‘desire to know’.

Abstract:
This chapter discusses mid-Victorian natural history sciences, focusing on the disputes over the classification within both the zoological and botanical communities. Zoologists argued over the merits of William Macleay’s quinary system, claiming that all organisms could be classified in groups of five. Botanists attacking the Linnaean or sexual system were divided over what should replace it; the most widely used of its rivals was known as the natural system. Several metropolitan naturalists felt the need to bring stability by settling these arguments. Hugh Strickland was the most prominent zoological stabiliser, an opponent of quinarianism and other forms of classificatory radicalism. Strickland established the world’s first formal rules of zoological nomenclature and attempted to use the authority of the British Association to impose them on naturalists.
