Abstract (sommario):
Bees provide the essential ecosystem service of pollination, contributing ca. 35% of global food production, but declines in their populations have been reported worldwide. Currently, one third of the Irish bee fauna is listed as threatened. This thesis aimed to provide essential information on the conservation genetics and ecology of Irish bees. A comparis?n of published data on microsatellite markers revealed that haplodiploidy alone had no influence on genetic div~rsity whereas eusociality probably reduced it. Globally, >90% of bee species are solitary, rather than social. Ireland has over 75% of the Atlantic zone populations of Colletes floralis, an endangered solitary species. Using novel microsatellite markers,' C. floralis populations exhibited considerable genetic and geographic structuring, with little evidence of inbreeding. The taxonomy of Bombus sensu stricto is complicated by intraspecific variation. ' Phylogenetic analyses of CO1 sequences confirmed a barcoding gap between three cryptic species of the B. lucorum complex. A novel PCR-RFLP method differentiated and described the Irish distribution of them. Furthermore, an independent dataset of Irish bumblebee species tested alternative hypotheses regarding bumblebee declines. Despite parallel declines in Britain and Ireland, there was no relationship between declines and species' European ranges or food-plant specialisatiOIi.. The majority of Ireland's landmass is involved in agriculture, necessitating the accurate description of bee communities within the remaining areas .of conserved habitat. A survey of protected sites found that calcareous grasslands and dry heaths had the highest diversity 'and density of bees, respectively. Despite considerable niche overlap, communities were not highly competitively structured. Up to 72% of the variation in species-abundance distributions could be explained by characters relating to nesting habitat. Only upon integrating population genetics, intrinsic site characters and extrinsic, landscape scale, factors will habitat management translate into sustainable conservation management of Irish bees and the pollination services they provide.

Abstract (sommario):
Doutoramento em Biologia
Existe um consenso generalizado de que o estudo da biologia reprodutiva de espécies endémicas, raras ou ameaçadas é essencial para compreender o seu estado actual e no desenvolvimento de estratégias adequadas de conservação in situ e ex situ. Polygala vayredae Costa (Polygalaceae) é uma espécie endémica da cadeia pré-Pirenaica oriental classificada como vulnerável de acordo com as categorias da IUCN. Os objectivos da presente Tese de Doutoramento consistiram em estudar a biologia reprodutiva de P. vayredae, avaliando de que forma pode afectar o ciclo de vida, em fornecer informação de base para futuros programas de conservação e em explorar em maior profundidade as interacções planta-animal e os processos de evolução de determinados traços florais. Para alcançar estes objectivos foram investigados os seguintes tópicos: biologia floral e sistema de reprodução (Capítulo 2), mecanismo de apresentação secundária de pólen (ASP, Capítulo3), ecologia da polinização (Capítulo 4) e mecanismos de dispersão (Capítulo 5). Os resultados revelaram que (1) P. vayredae depende estritamente de vectores de polinização para produzir sementes, (2) as suas características florais (corola fechada, accionada por comportamentos específicos do insecto) limitam o conjunto de polinizadores eficientes, (3) a sua longevidade floral favorece a transferência de pólen mas apresenta também custos reprodutivos sobre o êxito feminino, (4) a ASP acarreta custos reprodutivos sobre o êxito das componentes masculina e feminina, (5) as flores de P. vayredae são visitadas por um diversificado conjunto de insectos, dos quais apenas quatro espécies se comportam como polinizadores eficientes, (6) os polinizadores eficientes são, frequentemente, escassos e variáveis ao longo do tempo e do espaço, (7) os visitantes ineficientes exercem um efeito negativo sobre o comportamentos dos polinizadores eficientes e consequentemente sobre o êxito masculino (reduzindo o fluxo de pólen) e feminino (reduzindo a produção de frutos e sementes), (8) a dispersão dos frutos alados a longas distâncias encontra-se largamente reduzida, e finalmente, (9) a dispersão é maioritariamente efectuada por formigas que dispersam as sementes a distancias reduzidas, com o conjunto de espécies variando grandemente entre populações e anos. Perante estas observações podemos concluir que P. vayredae apresenta os seguintes problemas reprodutivos: limitação de pólen/polinizadores e curtas distâncias de dispersão. Os programas futuros de conservação que considerem estes pontos, conservando a fauna da área e protegendo as interacções planta-animal, promoverão a manutenção das populações e, consequentemente, a conservação desta espécie.
There is a consensus that studies on the reproductive biology of endangered, rare or threatened species are useful for understanding their current status and for evaluating in situ and ex situ management strategies. Polygala vayredae Costa (Polygalaceae) is a narrow endemic species from oriental pre-Pyrenees classified as vulnerable according with the IUCN categories. The aims of this PhD thesis were to study the reproductive biology of P. vayredae, to evaluate the implications of its reproductive features on its life cycle, to provide valuable background information for future management programs and deeply explore plant-animal interactions and the evolution of certain floral traits. To achieve the proposed objectives the following points were investigated: the floral biology and breeding system (Chapter 2), the singular secondary pollen presentation (SPP) mechanism (Chapter 3), the pollination ecology (Chapter 4) and the dispersal mechanisms (Chapter 5). The results revealed that (1) P. vayredae strictly depends on pollen vectors to produce seeds, (2) its floral features (closed corolla and the need to be trigged by specific behaviours of the insects) limit the spectrum of efficient pollinators, (3) its floral longevity favours the opportunity to pollen transfer but also have reproductive costs over female fitness, (4) SPP imposes several reproductive costs over male and female fitness, (5) a large spectrum of floral visitors were observed, but with only four species being efficient pollinators, (6) efficient pollinators were scarce and highly variable both along time and space, (7) inefficient visitors add a negative effect on the behaviour of efficient pollinators and on male (reducing pollen flow) and female components (reducing fruit set and seed ovule ratios), (8) long dispersal of the alate fruits is largely reduced, and finally, (9) dispersal is mainly performed by ants who are able to disperse seeds for short distances, with the spectrum of ant species being spatially and temporally variable. The general conclusions on the status of P. vayredae indicate that this species bears the following reproductive problems: pollen/pollinator limitation and short distance dispersal of the diaspores. Future management programs that account with this issues conserving the fauna of the area and protecting plant-animal interactions will facilitate the maintenance of the populations and thus its conservation.

Childerhouse, Simon, e n/a. "Conservation biology of New Zealand sea lions (Phocarctos hookeri)". University of Otago. Department of Marine Science, 2008. http://adt.otago.ac.nz./public/adt-NZDU20080213.144055.

Testo completo
Abstract (sommario):
New Zealand sea lion (Phocarctos hookeri) is a pinniped endemic to New Zealand and is among the rarest of sea lion species. New Zealand sea lions are incidentally caught in the trawl fishery for squid around the Auckland Islands, and a sea lion catch-limit or Fishing Related Mortality Limit (FRML) is used to manage this interaction. Since 2003 such limits have been calculated using an age-structured Bayesian population model. One problem with this approach is that several key demographic parameters have had to be assumed, or are based on very few data. Archaeological and other historical records demonstrate that New Zealand sea lions were substantially more widespread before the arrival of humans to New Zealand than they are today (Chapter 2 published as Childerhouse & Gales 1998). The present population size is clearly reduced, with subsistence and commercial hunting the most likely cause of historical changes in distribution and abundance. Campbell Island, the only significant breeding site outside the Auckland Islands, was thoroughly surveyed for New Zealand sea lions for the first time in 2003. An estimated 385 pups were born there, comprising 13% of the total pup production for the species for 2003 (Chapter 3 published as Childerhouse et al. 2005). This thesis provides the first robust estimates of several demographic parameters for New Zealand sea lions. These data were gained via the capture, tagging and ageing of 865 individual females, which had come ashore to pup between 1999 and 2001. This research was underpinned by the development of a novel and robust ageing technique for live New Zealand sea lions (Chapter 5 published as Childerhouse et al. 2004). Chapters 6, 7 and 8 used analyses of the age structure of these females, and of subsequent resightings of them, and of known-age females between 1998 and 2005, provided the first estimates of individual growth, mean reproductive rate (0.67, SE = 0.01), mean adult survival (0.81, SE = 0.04), and maximum age (28 years) for females. These data show that New Zealand sea lions are among the slowest growing, slowest reproducing, and longest lived sea lion species. Significant differences in the age structure of the two largest breeding colonies highlight flawed assumptions of the current management approach. The application of this new demographic information has the potential to significantly alter the existing management advice relating to the setting of FRMLs and the impact of the squid fishery on the New Zealand sea lion population. Taken alone, these results suggest a dim outlook for an already threatened species. In the context that pup production is in significant decline (e.g. 32% since 1998 Chilvers et al. 2007), the species� foraging environment is thought to be marginal (Costa & Gales 2000), and that resource competition may also be impacting on the population (Chapter 4 published as Childerhouse et al. 2001a), the picture darkens further. Taken as a whole, these data suggest that current management is insufficient to ensure population stasis, let alone meet the Government�s statutory goal of recovery.

Testo completo
Abstract (sommario):
The bottlenose dolphins of Fiordland, New Zealand, live at the southern limit of the species' worldwide range. They are exposed to impacts from tourism and habitat modification, particularly in Doubtful Sound, and their conservation requirements are presently unclear. Dolphin abundance was estimated in Doubtful Sound using photo-identification census and capture-recapture techniques (56 individuals; 95% CI: 55-57), detecting a decline of 34-39% over 12 years among adults and sub-adults (>3 years old). The cause of this decline was investigated via demographic modelling in Doubtful Sound and a comparative assessment of population status in Dusky Sound. Capture-recapture modelling of photo-identification data compiled since 1990 yielded a constant adult survival rate marginally lower than prior estimates for wild bottlenose dolphins ([phi]a(1990-2008) = 0.9374; 95% CI: 0.9170-0.9530). Survival of calves (<1 year old) declined to an unsustainable level that is thought to be the lowest recorded for wild bottlenose dolphins ([phi]c(2002-2008) = 0.3750; 95% CI: 0.2080-0.5782) coincident with the opening of a second tailrace tunnel for a hydroelectric power station. Reverse-time capture-recapture modelling detected declines in recruitment (f(1994-2008) = 0.0249; 95% CI: 0.0174-0.0324) and population growth ([lambda](1994-2008) = 0.9650; 95% CI: 0.9554-0.9746) over time consistent with the decline in calf survival (<1 year old) and a separate reduction in juvenile survival (1 to 3 years old) reflecting cumulative impacts. Dolphin abundance was estimated in Dusky Sound using photo-identification census and capture-recapture techniques (102 individuals, 95% CI: 100-104) providing no evidence of interchange with Doubtful Sound. A comparative assessment of health status between Doubtful and Dusky Sounds revealed skin lesioning was more severe in Doubtful Sound, particularly among females, and newborn calves appeared to be smaller and were born over a shorter period: factors that may contribute to the low levels of calf survival in Doubtful Sound. The Fiordland bottlenose dolphins were assessed under IUCN Red List regional criteria. The small size of the population (205 individuals, 95% CI: 192-219) combined with the projected rate of decline in stochastic matrix models (average decline 31.4% over one generation) resulted in a recommended classification of Critically Endangered.

Abstract (sommario):
Of the 6,500 or so different mammal species on earth, approximately 1,406 are from one group—bats! In other words, over 20% of known mammal diversity are bats. This module covers the basic biology and ecology of bats, the ecosystem services they provide, the threats they face globally, and how conservation actions can mitigate these threats. Students focus more locally in an accompanying exercise, Field Guide to the Bats in Your Neighborhood, where students are asked to research and present on bats in their region. In the case-study based exercise, Bats in the City? An Exploration of Acoustic Monitoring of Bats, students analyze acoustic data to answer ecological questions. Overall, students are introduced to bat ecology and conservation, urban biodiversity, bat echolocations/vocalizations, and the monitoring of these species through analyzing acoustic recordings with specialized software, Kaleidoscope. These materials were made in association with City Bats, a program in New York City designed to teach students more about the scientific process and urban biodiversity.

Abstract (sommario):
The Magnuson-Stevens Fishery Conservation and Management Reauthorization Act of 2006 mandat¬ed the research and management of the nation’s deep-sea coral resources through establishment of the National Oceanic and Atmospheric Administra¬tion’s Deep Sea Coral Research and Technology Program. The challenge for Alaska was daunting, where expansive, world-class fisheries often coincided with extraordinarily rich coral habitats for a high-latitude region. The first chal¬lenge was to inventory known locations of deep-sea corals. Many coral records and some museum collections existed from Alaska, but the taxonomy of cor¬als was little studied and field iden¬tification of corals was problematic. Formal bycatch programs and research activities in recent decades provided many more specimens for taxonomic study, but guides to species were largely incomplete, inaccurate, and outdated given the fast pace of species discovery in Alaska. We provide a comprehen¬sive, up-to-date guide, detailing 161 coral taxa identified from museum collections, primary literature, and video records. Each profile includes a description, images for each taxon, taxonomic history, biology, ecology, geographical distribution, and habitat, including depth distribution. Corals are found in the six regions of Alaska but the coral fauna of the Aleutian Islands is by far the most species rich. The state of taxonomy for some coral groups is ex¬cellent, while others require additional collections and more taxonomic work. Construction of this guide resulted in descriptions of several antipatharian species, published separately from this guide (Alternatipathes mirabilis, Bathypathes alaskensis, B. ptiloides, B. tiburonae, and Parantipathes pluma) and the scleractinian Flabellum (Flabel¬lum) oclairi Cairns, sp. nov. described herein. The guide provides informa¬tion for targeting new collections and identifying areas of high abundance and indicator species of vulnerable marine ecosystems. Stakeholders can now more adequately assess Alaska’s coral resources and risks from natural and anthropogenic stressors.

Abstract (sommario):
The Tripletail, Lobotes surinamensis, is a pelagic fish found in tropical and sub-tropical waters of all oceans. Tripletails are often associated with floating debris and make frequent incursions in bays and estuaries where they are targeted by recreational fishermen. In Mississippi waters the species is typically present during the late spring and summer season that also correspond to the period of sexual maturation and spawning (Brown-Peterson and Franks 2001). Tripletail is appreciated as a gamefish but is also prized for its flesh of superior quality. The fast growth rate of juveniles in captivity documented by Franks et al. (2001) and the excellent quality of Tripletail flesh both contribute to the potential of this species for marine aquaculture. In addition, the production of cultured juveniles would be precious to develop a better understanding of the biology, early life history and habitat use of Tripletail larvae and juveniles, a topic largely undocumented to date, through experimental releases and controlled studies. The culture of tripletail thus supports the Tidelands Trust Fund Program through improved conservation of natural resources, potential enhancement of fisheries productivity and potential development of a new economic activity on the Gulf coast producing tripletail via aquaculture. The Objective of this project was to initiate development of methods and techniques needed to spawn captive held tripletail broodfish and raise their offspring to evaluate their growth and development in captivity. In this report we will present the results of studies aiming to develop methods and protocols for captive spawning of tripletail and the first data obtained on the early development of tripletail larvae. A major issue that was encountered with tripletail broodstock development during the project lied in the difficulties associated with identifying the sex of adults caught in the wild and candidates for being incorporated in mating sets for spawning. This issue was addressed during the course of the project by examining the potential of a non-lethal method of hormonal sexing. The results of these preliminary investigations are presented in the third part of this report. All protocols used in the project were determined with the guidance of the Institutional Animal Care and Use Committee (IACUC) of the University of Southern Mississippi (USM IACUC protocol number 10100108).
