Pełny tekst źródłaThis thesis addresses different challenges related to the conservation of freshwater biodiversity in the Iberian Peninsula using aquatic macroinvertebrates as a model system. This information will contribute to a better understanding of the determinants that affect and threat aquatic macroinvertebrate biodiversity and, aims to provide insights for use in nature conservation policies. Chapters 1 and 2 focus on the assessment of potential biodiversity surrogates in aquatic ecosystems, while Chapter 3 is dedicated on the effectiveness of protected areas networks in representing freshwater diversity. In Chapter 4, starting from new records of an alien aquatic insect detected in the Iberian Peninsula, global potential distribution maps for this species are produced since the prevention of biological invasions is the most cost-effective way to avoid problems related with nature conservation. Chapter 1 reveals that mountainous national parks in Spain contain a large percentage of the overall Iberian biodiversity with respect to aquatic macroinvertebrates at family level. Coleoptera family richness displays the highest correlation with the other taxonomic groups and remaining richness values and may be used as a macroinvertebrate biodiversity surrogate in well preserved mountainous areas. Such a taxonomic indicator could be complemented by the use of Odonata family richness in case of standing waters. Chapter 2 assesses the performance of a charismatic group (waterbirds) as surrogate of macroinvertebrates biodiversity in wetlands. The results show limited concordance between the community composition of waterbirds and macroinvertebrates, and negligible or negative correlations between the metrics of their taxonomic richness. Contrasting responses to environmental gradients were detected and waterbirds can therefore be considered poor indicators of aquatic biodiversity in these ecosystems. Chapter 3 provides the first attempt at assessing the effectiveness of protected areas in representing alpha, beta and gamma components of taxonomic and functional macroinvertebrate diversity at different spatial scales. The main findings highlight the contrasting performance of reserve systems in the maintenance of taxonomic and functional freshwater diversity, and point to a bias in environmental representation within protected area networks. Importantly, this mismatch means that caution should be exercised when using any one diversity component as a surrogate for others, and emphasizes the importance of adopting an integrative approach to biodiversity conservation in aquatic ecosystems. The last chapter focuses on Trichocorixa verticalis verticalis (Corixidae, Hemiptera), one of the few exclusively aquatic insects that can be considered as an alien species, and for which large populations have been newly recorded in numerous Ramsar wetlands in Andalusia (south-west Spain). The predictive maps obtained of current potential distribution suggest that this corixid may expand well beyond its current range and find inhabitable conditions in temperate areas across a wide range of latitudes. When considering a future climatic scenario, the suitability area showed only limited changes compared with the current potential distribution. The results allow the detection of potential contact zones among currently colonized areas and potential areas of invasion, as well as zones with a high level of suitability overlapping areas recognized as global biodiversity hotspots. These results, taken as a whole, point to some of the main challenges for the conservation of aquatic macroinvertebrate biodiversity (biodiversity surrogates, reserve performance and biodiversity threats) and provide useful information about important topics that concern protected area managers and conservationists.

Lotic ecosystems are highly complex interacting with acting factors in different spatial and temporal scales. Small forested streams receive direct influence of the surrounding vegetation through the input of organic matter which is the base of the food chain in these ecosystems. I studied the effect of the reduced-impact selective logging on communities of aquatic insects streams to test the hypothesis that communities are affected by their impacts. Despite the metrics used appropriately capture the impact, there were no negative effects on insect communities. However, the results of this study may not be generalizable to other systems because we studied only a fraction of the diversity of Amazonian streams, specifically the insect orders Trichoptera, Plecoptera and Coleoptera. In addition, the absence of the low impact management effects is dependent on the operating system adopted in each enterprise. Another predominant feature in any lotic ecosystem is its directional flow, which consequently affects the distribution of substrates, habitats, and food resources within the streams. I studied the effects of water flow taking it as the main predictor of the selective effect of habitat on the attributes of insect taxa. My hypothesis was confirmed by showing that most rapid flowing streams in Amazon has faunas with morphological and ecological attributes of greater resistance to flow. Environmental factors such as the preference for habitats, dispersive limitation and biotic interactions are among the main mechanisms responsible for structuring communities, and has been widely emphasized in the context of metacommunity theory. A metacommunity is defined as the set of communities in a region which are interconnected by the flow of individuals, which emphasizes the spatial dynamics in structuring the diversity and composition of species in each local community. I tested the effects of environmental factors, spatial filters and biotic interactions in aquatic insects of forested streams of the Amazon, specifically the intraguild segregation and interguild predation effect. My results support the existence of predation effects on the organization of the metacommunity, as evidenced by the exclusive fraction of the predators matrix on prey assemblages of different guilds, and still withstand environmental effects and dispersive limitation in different trophic guilds. The study developed in this thesis help us understand more clearly the effects of the selective logging impacts on aquatic insect communities, assist in understanding about what are the characteristics of the stream habitats filter ecological and morphological attributes of aquatic insects in the Amazon, and advance our understanding of the effects that biotic interactions may have on the structuring streams metacommunities.
Ecossistemas aquáticos lóticos são altamente complexos interagindo com fatores atuando em diferentes escalas espaciais e temporais. Especialmente pequenos riachos florestados recebem a influência direta da vegetação circundante por meio da entrada de matéria orgânica a qual representa a base da cadeia alimentar nestes ecossistemas. Estudei os efeitos do corte manejado de madeira sobre as comunidades de insetos aquáticos de riachos, testando a hipótese de que as comunidades seriam afetadas por estes impactos. Apesar das métricas utilizadas capturarem apropriadamente os impactos, não houveram efeitos negativos sobre nenhum aspecto das comunidades estudadas. Entretanto, os resultados deste estudo não podem ser generalizados considerando que estudamos apenas uma parcela da diversidade dos riachos, especificamente as ordens Trichoptera, Plecoptera e Coleoptera. Além disso, a ausência de efeitos do manejo de baixo impacto é dependente do regime de exploração adotado em cada empreendimento. Outra característica predominante em qualquer ecossistema lótico é seu fluxo direcional da correnteza, que por conseguinte, afeta a distribuição dos substratos, habitats, e de recursos alimentares dentro dos riachos. Estudei os efeitos da velocidade do fluxo tomando-o como o principal preditor do efeito seletivo dos hábitats sobre os atributos das espécies. Minha hipótese foi corroborada, mostrando que riachos de águas mais correntes apresentam faunas com atributos morfológicos e ecológicos de maior resistência a correnteza. Fatores ambientais, como a preferência por habitats, limitação dispersiva e interações bióticas estão entre os principais mecanismos responsáveis pela estruturação de comunidades, e tem sido amplamente enfatizados no contexto da teoria de metacomunidades. Uma metacomunidade é definida como o conjunto de comunidades numa região que são interligadas pelo fluxo de indivíduos, o que enfatiza a importância das dinâmicas espacias estruturando a diversidade e composição de espécies em cada comunidade local e para a diversidade regional. Testei os efeitos de fatores ambientais, filtros espaciais e interações bióticas em insetos aquáticos de riachos florestados da Amazônia, especificamente padrões de segregação intraguildas, como um sinal de competição, e da predação entre guildas, assumindo explicitamente que a abundância e distribuição de predadores devem seguir a disponibilidade das presas consumidas. Meus resultados suportam a existência de efeitos de predação sobre a organização da metacomunidade, como evidenciado pela fração exclusiva da matriz de predadores sobre a comunidade de presas de diferentes guildas, além de suportar efeitos ambientais e limitação dispersiva em diferentes guildas tróficas. Os estudo desenvolvidos na presente tese ajudam a compreender mais claramente como os efeitos dos impactos do corte seletivo de madeira podem afetar comunidades de insetos aquáticos, auxiliam na compreensão de quais são as características dos hábitats selecionando atributos ecológicos e morfológicos de insetos aquáticos na Amazônia, e avançam nossa compreensão dos efeitos que as interações bióticas podem causar sobre a estruturação das metacomunidades de riachos.

Pełny tekst źródłaEstudiar los procesos evolutivos que ocasionan la biodiversidad actual puede ayudarnos a comprender mejor como la riqueza de especies está distribuida de forma desigual en diferentes clados. Una de las causas principales para explicar este fenómeno es el desarrollo de innovaciones clave que modifican las capacidades de las especies para sobrevivir en nuevos ambientes, acceder a nuevos recursos, o para lidiar la competencia con otras especies. Esta tesis se focaliza en explicar las consecuencias macroevolutivas de dos de las transiciones de hábitat más comunes en ecosistemas acuáticos: aquellas entre ecosistemas con diferente nivel de salinidad, y aquellas entre ecosistemas de aguas corrientes y aguas estancas. Entre los habitantes de ambientes acuáticos, los escarabajos son uno de los grupos más diversos, con especies capaces de vivir en todo tipo de ambientes, incluyendo aguas corrientes y estancas, y en ocasiones, ambientes salinos. Las familias más diversas de escarabajos acuáticos son Hydrophilidae, Dytiscidae e Hydraenidae, aunque solo la primera ha sido estudiada desde una perspectiva evolutiva. En esta tesis, evaluamos los patrones evolutivos de varias tribus pertenecientes a las otras 2 familias. A pesar de que los escarabajos acuáticos son un grupo bien estudiado en general, ha sido necesario realizar modificaciones en la clasificación de algunos grupos para reflejar su verdadera historia evolutiva, describiendo un nuevo género y tres subgéneros para la tribu Hygrotini. Adicionalmente, se han realizado pequeñas modificaciones tanto en Hygrotini como en Ochthebiini, siendo la base sobre la que se han desarrollado los posteriores estudios filogenéticos de esta tesis. Las transiciones entre ambientes con diferente nivel de salinidad han sido estudiadas para Hygrotini (familia Dytiscidae, Capítulo 2) y Ochthebiini (familia Hydraenidae, Capítulo 5). Se han detectado múltiples orígenes de la tolerancia a la salinidad, adquiriéndose esta característica de forma gradual en la mayoría de los casos. Los casos en los que se han descubierto transiciones directas de ambientes de agua dulce hacia ambientes hipersalinos, son clados aislados en la filogenia y asociados con ambientes de charcas costeros. Además, la tolerancia de aguas hipersalinas ha demostrado ser una característica irreversible, aunque no por ello se trata de un dead-end evolutivo (callejón sin salida), ya que las especies que viven en estos ambientes conservan su capacidad de diversificación, llegando incluso a ser superior a la de otras especies (por ejemplo, el subgénero Cobalius, Capítulo 5). A si mismo, nuestros resultados relacionan el origen de linajes tolerantes a la salinidad con periodos de aridificación a escala global, un patrón que confirma el encontrado en la familia Hydrophilidae. En cuanto a las transiciones entre aguas corrientes y estancas estudiada en Hydroporini (familia Dytiscidae, Capítulo 6), hemos encontrado patrones similares en las especies que viven en ambos ambientes, aunque los análisis sugieren la posibilidad de una mayor tasa de diversificación en ambientes de aguas estancadas. Nuestros resultados han destacado una correlación entre la preferencia del hábitat de las especies con su tamaño corporal, de manera que las especies que se encuentran en ambientes más especializados (en aguas corrientes) son aquellas con menor tamaño. Adicionalmente, se ha demostrado que la transición entre ambientes no es per se un factor que afecta al tamaño corporal de las tesis. Finalmente, gracias a los numerosos trabajos de campo realizados enfocados en los ambientes salinos, se ha podido describir la especie Ochthebius (Micragasma) minoicus (Capítulo 4).

Pełny tekst źródłaWhite croaker (Genyonemus lineatus) are a sentinel fish species for contamination due to their direct interaction with contaminated sediments through benthic foraging. White croaker within the Los Angeles and Long Beach Harbor exhibited hierarchical habitat selection: avoiding dredged areas while selecting for areas of high sediment total organic carbon (4.8–8.1%), high polychaete density (406–700 polychaetes/0.1 m2), and small sediment grain size (<23.5 µm). Model results suggest that these fish are moving into shallower waters at night to forage and may refuge more during the day to avoid predation. The predictive model for white croaker habitat use indicated three important areas of use within the LA-LB Harbor: Consolidated Slip, Inner LB Harbor, and Fish Harbor. The areas containing the most preferable habitat to white croaker are also areas of high sediment contamination, and thus are the likely locations where these fish are acquiring contaminants.

Pełny tekst źródłaThe Magnuson-Stevens Fishery Conservation and Management Act (MSA; Magnuson-Stevens Fishery Conservation and Management Act. 2014. (16 U.S.C. 1801–1891(d)) mandates that fisheries management councils in the United States prevent adverse, or “more than minimal and not temporary”, fishing effects to essential fish habitat (EFH) to the extent practicable. Councils were left to decide what effects qualified as “minimal” and “temporary”. The lack of explicit definition in the MSA and its accompanying Final Rule has resulted in inconsistent habitat management throughout the country. The EFH mandate was written under an implicit assumption that councils have the scientific information necessary to effectively manage EFH. Basic information is lacking, such as what type of habitat occurs where, and how fishing effects habitat features. Chapter 1 briefly reviews the history of EFH regulation, the consequences of regulatory ambiguities and information gaps, and highlights that high latitude fisheries management can be disproportionately affected by climate variability. Thus, requiring investment in baseline habitat assessment and monitoring and renewed focus on under developed areas of research e.g. Fishing effects and gear-habitat interactions.
Councils have attempting to quantitatively describe fishing effects to EFH through the use of mathematical models. The most recent of which, the Fishing Effects (FE) Model, was used in the North Pacific Fisheries Management Council 2015 EFH Review cycle. The FE Model uses discrete time steps (monthly) and spatially explicit fishing effort and sediment data to calculate an estimated habitat disturbance. The FE Model is calculated in two-dimensions and implicitly assumes that if fishing gear does not contact the seabed, then there is no gear-habitat interaction. Some features stand taller than raised gear (e.g. sea whips, Halipteris willemoesi, in the North Pacific can up to 2m tall) and may interact with fishing gear. The FE Model in two-dimensions does not account for this potential interaction and cannot effectively simulate gear modifications. Chapter 2 proposes an adapted version of the FE Model that accounts for the vertical interactions through the use of discrete height bins. To accurately estimate interactions on and above the seabed, fishing gear has to be recharacterized. To demonstrate this the Bering Sea flatfish trawl was recharacterized by calculating how much of the nominal gear width is present in each height bin. A detailed methodology is provided to allow this method to be applied to any fishing gear. The adapted FE Model can be used to simulate gear modifications, as is shown by simulating two modifications of the flatfish trawl. This chapter will inform the 2020 EFH Review cycle as the FE Model is improved.
