    The harbour seal Phoca vitulina and the grey seal Halichoerus grypus have been inhabitants of the Wadden Sea since millennia. Prehistoric findings indicate the presence of both species around 5000 BC. This changed dramatically in the mid Middle-Ages as around 1500 AC, the grey seal disappeared from the Wadden Sea as a consequence of persecution. With growing hunting pressure, especially in the 20th century and concurrent habitat destruction and pollution, the harbour seals reached all time low numbers in the 1970’s. Banning the hunt in countries around the southern North Sea, limiting pollution and protection from disturbance allowed the harbour seals to slowly recover and the grey seals to return to the Wadden Sea. In this thesis the population trends and inherent dynamics of the recovery for both species is described. Also the movements of individual animals are studied to explain possible mechanisms.

    Jaarlijks wordt in opdracht van het ministerie van Economische Zaken de Nederlandse otterpopulatiegenetisch gemonitord. Daarmee wordt een vinger aan de pols gehouden voor de ontwikkeling van degenetische status van de populatie. Deze vorm van monitoring, waarbij gebruik wordt gemaakt van DNAgeïsoleerd uit uitwerpselen en doodvondsten, maakt het tevens mogelijk veranderingen in de ruimtelijkeverspreiding en de populatieomvang te volgen. De monitoringsronde van 2015/2016 laat zien dat depopulatie verder is gegroeid naar ca. 185 individuen. Op populatieniveau is de genetische variatie weer wattoegenomen doordat op steeds meer plekken otters van Duitse origine in de Nederlandse populatie opduikendie hier op eigen kracht komen. De genetische variatie binnen individuen is niet verder afgenomen zoals deeerste periode van het herintroductieprogramma. Onderdeel van deze monitoring is ook autopsie van dodeotters, waarbij wordt gekeken naar de doodsoorzaak en de belangrijkste lichaamskenmerken. Verkeer isverreweg de belangrijkste doodsoorzaak. Het aantal verkeersslachtoffers neemt nog ieder jaar toe, waarbijde toename evenredig is aan de toename in de populatieomvang. Locaties waar otters worden doodgereden,worden geregistreerd en toegevoegd aan een database. Deze informatie is belangrijk om knelpuntlocatiesveiliger te maken om zo het aantal verkeersslachtoffers te beperken---The Ministry of Economic Affairs requires that the Dutch otter population is surveyed each year to monitorthe genetic status of the population using DNA isolated from spraints and tissue from dead individuals. Theresulting information is also used to detect changes in the spatial range and population size. The 2015/2016survey showed that the population size has further increased to about 185 individuals. The amount ofgenetic variation at the population level has further increased, mainly as the result of migration of otters ofGerman origin to the Dutch population. In contrast to previous years, genetic variation within individuals hasnot declined further. The survey includes autopsies of dead otters to assess body condition and the mostlikely cause of death. Traffic is by far the most important cause of mortality. The annual number of road killsis still increasing in proportion to the increase in population size. Locations where road kills occur areregistered and added to a database. This information is important to localise places where mitigatingmeasures have to be taken to improve the safety for otters

    This report presents the Favourable Reference Values for population size and range for the species listed in Annexes II, IV and V of the EU Habitats Directive. These reference values are used to assess the conservation status of species as required by Article 17 of the Habitats Directive. They were determined according to a protocol (checklist) and based on scientific information. Where the required scientific information was not readily available, expert judgement was used to fill the gaps. When determining the reference values, experts on each of the species groups were enlisted from the various voluntary conservation organisations, IMARES Wageningen UR (Texel and IJmuiden) and Alterra Wageningen UR. In addition, two extra questions were answered on how these reference values can be maintained or achieved, and the potential influence of climate warming.

    Rond de eeuwwisseling zat er plots weer volop ansjovis in de Noordzee. Daar was geen Brussels overleg of een visquotum aan te pas gekomen. Net een beetje warmer zeewater was voldoende om het visje over het dooie punt heen te helpen, denkt Kristina Raab. Op 10 oktober promoveert ze op onderzoek naar deze ansjovis-explosie, dat ze uitvoerde bij IMARES en de leerstoelgroep Aquacultuur en visserij. Haar onderzoek past binnen de internationale wetenschappelijke interesse voor de grote populatieschommelingen bij ansjovis.
    The numbers game in wildlife conservation: changeability and framing of large mammal numbers in Zimbabwe

    Wildlife conservation in terrestrial ecosystems requires an understanding of processes influencing population sizes. Top-down and bottom-up processes are important in large herbivore population dynamics, with strength of these processes varying spatially and temporally. However, up until recently the role of human-induced top-down and bottom-up controls have received little attention. This is despite the fact that almost all terrestrial ecosystems are influenced by human activities thereby likely altering the natural control of animal populations. Therefore, in this thesis, the role of natural and human-induced controls in influencing large herbivore populations and how human controls (i.e., policy instruments, incentives and provisions) influence human activities and wildlife conservation in a semi-arid African savanna ecosystem are investigated. This study primarily focuses on Gonarezhou National Park (hereafter, Gonarezhou), Zimbabwe and adjacent areas. Zimbabwe experienced an economic crisis and political instability between 2000 and 2008 following the land reforms that started in 2000 which were widely covered in the mass media.

    The results indicated a weak synchrony in rainfall and drought occurrence (natural bottom-up process) in areas within the same “climatic” region, and variable responses of large herbivore species to the 1992 severe drought with most large herbivore species’ populations declining following the 1992 drought and increasing thereafter. Therefore, droughts are important in influencing large herbivore populations in semi-arid ecosystems. Furthermore, the results showed variation in the intensity of illegal hunting (top-down human control) which was associated with variation in law enforcement efforts in Gonarezhou. Law enforcement efforts in Gonarezhou were strengthened in 2004 following the employment of additional patrol rangers which resulted in increased park coverage and a decline in recorded illegal activities. Thus, the results show that political instability and economic collapse does not necessarily lead to increased illegal hunting in situations where policy instruments, such as laws, are enforced.

    A higher perceived effectiveness of Communal Areas Management Programme for Indigenous Resources (CAMPFIRE - a community-based program that allows local people living in communal areas near protected areas in Zimbabwe to financially benefit from using the wildlife resources within their area) was partly associated with a decline in human-wildlife conflicts. In addition, local communities with higher perceived effectiveness of CAMPFIRE programs partly had more favourable attitudes towards problematic wild animals. Moreover, the results showed that in the 1990s, the majority of newspaper articles highlighted that wildlife conservation in Zimbabwe was largely successful. However, following the land reforms that occurred in 2000, the international media lost interest in wildlife conservation in Zimbabwe, as evidenced by a sharp decline in published articles. Also, the frames changed in the international media with the “political unrest and land reform” blame frame becoming more dominant, and nature conservation was portrayed more negatively. The change in media frames shows that there was a spill-over effect from the political domain into wildlife conservation following Zimbabwe’s land reforms in 2000.

    Overall, this study provides new insights on the processes influencing large herbivore population dynamics in human-dominated semi-arid savanna ecosystems which consist of diverse wildlife management regimes and also illuminates the importance of media framing and (mis-)representation of wildlife conservation issues following political instability, crisis or societal unrest. With these findings, it is concluded that natural bottom-up processes (e.g., droughts) influence large herbivore population dynamics whereas policy instruments, incentives, provisions and societal frames mainly have a top-down effect on wild large herbivore populations in savanna ecosystems.

    Dit rapport beschrijft een deel van de werkzaamheden die in het kader van het onderzoeksproject "Populatiebeheer overzomerende (Grauwe) ganzen" in 2009 en 2010 zijn uitgevoerd. Het aantal ganzen dat in Nederland broedt neemt de laatste decennia spectaculair toe. Dit toenemende aantal ganzen veroorzaakt een zodanige maatschappeleijke overlast dat aantalregulerende maatregelen worden overwogen. Het is echter nog onduidelijk welk effect de verschillende maatregelen hebben. Om hier meer inzicht in te krijgen is een ruimtelijk-expliciet, op individu gebaseerd, dichtheidsafhankelijk model ontwikkeld voor de Grauwe gans.
    Is there chaos out there? : analysis of complex dynamics in plankton communities

    Species often show irregular fluctuations in their population abundances. Traditionally, ecologists have thought that external processes (e.g., variability in weather conditions) are the main drivers of these ups and downs. However, recent theoretical work suggests that fluctuations in natural populations may also be driven by internal mechanisms (e.g., the interplay between species). In this thesis I use a combination of time series analysis and modeling to provide more insight into the question to which extent such internally generated chaos might drive the population dynamics of plankton communities under controlled as well as natural conditions. In short, this thesis demonstrates in theory and experiment that species in plankton communities may rise and fall forever in a chaotic way. This result challenges the traditional view that nature is at equilibrium and that only externally driven processes may disturb this equilibrium.

    De oorspronkelijke populatie Noordzeehouting (Coregonus oxyrhynchus) van het Rijnstroomgebied wordt beschouwd als uitgestorven sinds 1939. In 1992 is begonnen met een grootschalig uitzetprogramma van houting in Duitsland op basis van een Deense entpopulatie van de rivier de Vidå die uitmondt in de Noordzee. Hoewel de taxonomische status van houting en andere coregoniden (waaronder grote marene) nog veel onduidelijkheden bevat en aan wetenschappelijke discussie onderhevig is, is deze Deense populatie waarschijnlijk het meest verwant aan de oorspronkelijke houtingpopulatie Voor een adequate bescherming van deze houtingpopulatie is het van belang hoe deze populatie zich verder ontwikkelt, hoe trekpatronen zich ontwikkelen in het Rijnstroomgebied en welke habitats en migratiemogelijkheden daarbij van belang zijn en hoe grootschalige milieuveranderingen en klimaatveranderingen van invloed kunnen zijn op het toekomstig succes van de houting in het Rijnstroomgebied.
    Evaluating and optimizing stock enhancement of natural flatfish stock

    The overall objective of this thesis is to evaluate and optimize a stock enhancement program of natural population of
    flatfish in which artificially reared fish are released in coastal areas using turbot (Psetta maxima) as model. Biological
    and ecological criteria are developed to evaluate the likelihood for success, i.e. increasing the stock size, based on
    ecological knowledge. Special reference is given to processes involved in the regulation of the natural population, such
    as density-dependent and density-independent mortality and growth. Field data on the temporal and spatial variation in
    the abundance of age-0 turbot is analyzed and implications for stock enhancement are discussed. It is concluded that
    there is a solid theoretical background indicating that stock enhancement through releases of artificially reared juvenile
    individuals is a viable option for the turbot stock.
    Support for the hypothesis that stock enhancement is a viable option is provided by the results of a series of
    filed experiments conducted under a stock enhancement program in the southern part of Denmark. The focus of these
    experiments was on the growth and mortality of released fish in comparison to wild fish, and the importance of the
    characteristics of the release habitat. The growth of the released fish was similar to, or higher than, that of their wild
    counterparts, and the mortality, even though highly variable, was on a comparable level. No indication of replacement
    of the wild individuals with released ones was found. The importance of the release habitat was investigated by
    releasing turbot into three areas that differed in wind exposure. The area with the highest degree of wind-exposure was,
    as predicted, the area where the highest abundance of wild juvenile turbot was found. The highest growth of released
    individuals was not found in this area but was found in the one characterized by the lowest degree of wind-exposure, an
    atypical nursery ground for turbot. The effect of the release habitat on the growth could be related to the quality of the
    prey items observed in the stomachs of wild turbot sampled in the three areas. Besides the choice of a suitable release
    habitat, the release size of the fish and the conditioning to the release habitat was shown to be critical for survival of
    released fish. In order to study the mortality of the released fish, a methodology applying diffusion theory was
    developed and tested. Using this method the post-release mortality was found to be as high as 14%•day–1 for the 9 day
    period examined in 7.5 cm sized fish. Mortality decreased with increasing release size and became negligible at a
    release size of 17cm. After conditioning reared fish to the release environment allowing fish to develop their natural
    burrowing behavior prior to release, the post-release mortality was found to be insignificant.
    Since it was possible to enhance the turbot stock through releases of artificially breed individuals, stock
    enhancement may be considered as a supplement to traditional stock management. It can be applied in species with a
    turbot like life cycle where density-dependent regulation occurs early in life, and where the cost of production young
    fish is less than the gain in fisheries yield. As long as the artificially reared juveniles are added to the population after
    the stage where density-dependent regulation occurs, it can be expected that the released fish will contribute to the
    natural stock. Further, in order to optimize the outcome when stock enhancing, two aspects should be given special
    attention, 1) finding a proper release habitat where not only the food quantity but also its quality provides optimal
    growth conditions and 2) the risk of a server loss of fish during the post release period which can be avoided either by
    manipulating the size of the individuals released or by applying a conditioning period prior to the release.

    Vooral binnen het snuitkevergenus Otiorhynchus komen veel soorten voor die zich parthenogenetisch voortplanten. Sommige van deze soorten hebben in een beperkt deel van het areaal toch mannetjes. Voorbeelden hiervan zijn O, raucus, O. nodosus, O. rugosostriatus, O. scaber, O. veterator, O. sulcatus, O.fullo en O. ligustici. Het is gebleken dat exemplaren van bisexuele soorten 11 chromosomen bezitten, terwijl parthenogenetische soorten polyploïd zijn. De meeste parthenogenetische soorten zijn triloïd, maar er zijn ook soorten met zowel diploïde als tetraploïde xemplaren. Otiorhynchus rugifrons staat in de literatuur bekend als een triploïde soort. Volgens de literatuur zouden er ook mannetjes bestaan, maar waar deze voorkomen is onbekend. In deze bijdrage wordt het voorkomen van bisexuele populaties van O. rugifrons in Frankrijk (Bretagne) en Groot-Brittanië (Engeland en Wales) vermeld. Een korte beschrijving van het mannetje wordt gegeven en afbeeldingen van zowel het manlijke als het vrouwelijke genitaal worden gepresenteerd. Daarnaast wordt de verspreiding in Europa en de ecologie van de soort besproken

    The book presents approaches and methodologies for predicting the structure and diversity of key aquatic communities (namely diatoms, benthic macroinvertebrates and fish), under natural conditions and under man-made disturbance. Such an approach will make it possible to: 1) set up procedures for robust and sensitive ecosystem evaluation, based on the prediction of the expected community structure; 2) model community structure in disturbed ecosystems, taking into account all the relevant ecological variables; 3) test ecosystem sensitivity to natural and anthropic disturbance; and 4) explore specific actions to be taken for the restoration of ecosystem integrity.
