Повний текст джерелаGaps in our knowledge of the functional roles of snakes within ecosystems limit our ability to predict the potentially cascading effects their removal from an ecosystem might create. Extirpation of snake species could potentially result in losses of ecosystem functionality if those taxa are ecologically unique. I used pitfall and funnel trap arrays, artificial cover object surveys, active searching, and passive camera trapping, as well as pre-existing faunal diversity data to identify terrestrial tetrapod species within the Koeberg Private Nature Reserve. This resulted in a list of 265 species, of which 13 were snakes. I then gathered data on dietary and four additional functional traits for each species from the literature. Next, using hierarchical and partitioning around medoids clustering, I identified ten broad dietary guilds and 54 functional guilds within the terrestrial tetrapod community. Of the dietary guilds Dasypeltis scabra was the only snake species that formed a unique single species guild and was one of four snake species (Pseudaspis cana, Homoroselaps lacteus and Lamprophis guttatus) to form four unique single species functional guilds. The remaining snakes clustered together within groups of other vertebrate predators. Functional diversity analysis was then used to simulate losing eight major taxonomic groups (birds, passerines, non-passerines, mammals, reptiles, snakes, non-snake reptiles and amphibians) and gauge the effects of those losses on overall community dietary and functional diversity. Functional diversity analysis revealed that the loss of certain snake species resulted in disproportionate losses of overall community dietary and functional diversity while losing others had negligible effects. These findings provide ambivalent support for the dietary and functional uniqueness of snakes suggesting that certain snake species are fulfilling unique functional roles within the ecosystem. Additionally, it is likely that losing those non-redundant species would result in significant losses of ecosystem functionality.

Doctoral thesis, Karlstads universitet, Institutionen för miljö- och livsvetenskaper, 2017. http://urn.kb.se/resolve?urn=urn:nbn:se:kau:diva-47636.
Повний текст джерелаMånga sötvattenmusslor har en komplex livscykel där larverna (glochidier) under sin utveckling till frilevande musslor parasiterar på gälarna hos lämpliga värdfiskar. Flera av våra musslor, såsom den tjockskaliga målarmusslan (Unio crassus), är globalt hotade och för att kunna bevara och förvalta dessa arter på bästa sätt behöver vi lära oss mer om deras ekologi och samspelet mellan musslan och dess värdfiskar. Avsaknaden av värdfiskar innebär förmodligen en stor begränsning för rekryteringen av juvenila musslor, men det finns trots detta en begränsad kunskap om hur artsammansättningen i fisksamhället och dess tillgänglighet påverkar musselpopulationer. Min avhandling undersöker olika aspekter av interaktioner mellan U. crassus och dess värdfiskar, som hur värdfisksamhällen och fiskarters värdlämplighet påverkar musslans reproduktionspotential. Jag har även studerat hur tätheter av olika fiskarter och vuxna musslor påverkar rekryteringen, eventuella evolutionära anpassningar samt om en förhöjd temperatur skulle kunna påverka interaktionen mellan U. crassus och dess värdfiskar. Resultaten visar att U. crassus är en generalist som parasiterar på en mängd olika fiskarter. Jag fann dock en stor variation i dominerande fiskarter och lämpliga värdar mellan olika åar, vilket påverkade reproduktionspotentialen hos musslorna mer än vad tätheten vuxna musslor som deltog i reproduktionen gjorde. Som ekologiskt viktiga värdar fanns således både särskilt lämpliga, primära värdarter, men också mindre lämpliga arter som förekom i höga tätheter. Ingen tydlig lokal anpassning kunde observeras, och fiskens närvaro påverkade inte tidpunkten för när de vuxna musslorna släppte sina glochidielarver. Däremot fann jag att temperaturen spelade en viktig roll för musslans reproduktion, där ökad temperatur föreslås ha negativa effekter på interaktionen mellan musslan och dess värdfiskar. Avhandlingen visar på vikten av att studera interaktioner mellan den tjockskaliga målarmusslan och dess värdar på lokal skala för att bättre kunna identifiera och prioritera viktiga naturvårdsåtgärder.

Повний текст джерелаOBJECTIVES: To determine the clinical significance of a population of scorpions, C. sculpturatus, found in New Mexico. This includes the toxicity of the venom as well as the interactions of venom and antivenom. METHODS: This project will include a descriptive retrospective study of clinical and laboratory data obtained through a patient chart and analytical laboratory procedures to positively identify the species of scorpion responsible for the envenomation. Scorpion Collection Scorpions from the location of the reported sting will be collected for venom analysis. Specific details and directions will be obtained from the grandparent of the victim regarding the campsite at Caballo Lake State Park. Human Subject – N/A Sample Size The sample size of specimens needed should be a minimum of 50 scorpions. This is due to factors which include; extremely small volumes of venom produced by each individual, the possibility of no venom production, damaged telson during collection (anatomical feature used in the delivery of venom), size variation in specimens and short window of opportunity to collect. Since these scorpions are more active during summer months, and travel time must also be accounted for, only a few months a year are acceptable. Instrumentation and Variables This is primarily laboratory assays rather than clinical. The clinical aspect, a case study involving the victim of a scorpion envenomation, was the reason behind needing to identify this Centruroides species. The analytical laboratory findings will be what will determine the exact species of Centruroides. A number of laboratory instrumentations and tests will be used or performed. These include; sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), SDS-PAGE with hyaluronic acid, turbidimetric absorbances of hyaluronidase, reverse phase high pressure liquid chromatography (RPHPLC), enzyme-linked immunosorbent assay (ELISA), lethal dose 50 (LD%) and effective dose 50 (ED50). Variables regarding these findings will include two main factors; the human factor and the instrumentation factor. First the human factor, samples collected must remain free of contaminants up to the point of analysis. The instruments RESULTS: 104 specimens were collected at Caballo Lake State Park. Four of these specimens were sent to a taxonomist and identified as C. sculpturatus. SDS-PAGE, turbidimetric HA, and RPHPLC showed no significant difference in venom between the New Mexico and Arizona Centruroides, but did show a significant difference between these two groups and the Mexico Centruroides. SDS-PAGE/HA and ELISA assays showed no significant differences between groups. LD50 and ED50 data were similar between New Mexico and Mexico Centruroides, both being more potent and more readily reversed by antivenom than the Arizona Centruroides. CONCLUSIONS: The assays which show possible differences between species, SDS-PAGE, SDS-PAGE-HA, turbidimetric HAase, RPHPLC, and ELISA were all identical between the New Mexico Centruroides species and the Arizona Centruroides sculpturatus. These findings were opposite when comparing New Mexico Centruroides species and the Mexico Centruroides limpidus limpidus. Three of the five assays showed a significant difference. Since the Mexico Centruroides limpidus limpidus is a known different species, this was expected. With this data the scorpion specimens collected in New Mexico have been identified as Centruroides sculpturatus. An interesting difference between the New Mexico and Arizona Centruroides sculpturatus was toxicity of the venom. The New Mexico groups had close to a two fold increase in toxicity. In fact, the toxicity of the New Mexico groups was equivalent to the Mexico Centruroides limpidus limpidus which is well documented as having an increased toxicity.

Повний текст джерелаMaire, Eva. "Socio-ecological drivers of fish biomass on coral reefs : the importance of accessibility, protection and key species." Thesis, Montpellier, 2018. http://www.theses.fr/2018MONTG027/document.
Повний текст джерелаCoral reefs have the greatest biodiversity of any ecosystem on the planet and support ecosystem goods and services to million people who depend directly on them for food, economic income, coastal protection and cultural values. Ecosystem accessibility, through road networks, is the main driver of their conditions, with the most accessible ecosystems being most at risk of resource depletion. To date, measuring accessibility to humans was strictly limited to examining the linear distance which ignores ragged coastlines and road networks that can affect the time required to reach fishing grounds. This thesis presents a double challenge: (i) developing new metrics of accessibility that account for seascape heterogeneity to better assess human impacts on coral reefs; (ii) evaluating the importance of coral reef accessibility, in interactions with their management, to explain variations of fish biomass. First, I developed novel metrics of reef proximity to human populations and markets based on the friction distance which is related to transport surfaces (paved road, dirt road, water) influencing the effective reach of human settlements. Travel time was used to build the gravity index, defined as human population divided by the squared travel time, to assess the level of human pressure on any reef of the world. I found that both travel time and gravity are strong predictors of fish biomass globally. Second, three applications using these new metrics highlighted that (i) gravity identified critical ecological trade-offs in conservation since reserves placed with moderate-to-high impacts may provide substantial conservation gains for fish biomass while reserve locations with low human impacts were more likely to support higher-order predation, (ii) using a study case in Northwest Madagascar, I illustrated how market proximity can affect fishermen communities and, ultimately, trigger changes in marine resources exploitation, and (iii) I implemented a new Community-Wide Scan (CWS) approach to identify fish species that significantly contribute to the biomass and coral cover on Indo-Pacific reefs and which provided tractable conservation targets. Within the context of global changes and biodiversity loss, the thesis challenges the sustainable and efficient management of coral reef socio-ecological systems with accessibility being the cornerstone

Повний текст джерелаThe evolutionary significance of some kinds of group living are well-known, some others such as the diapause aggregations remain poorly known although widespread. In this thesis, I tested if the arthropods form diapause aggregations to find their mates according to the hidden lek hypothesis with the ladybird Hippodamia undecimnotata. By using a Species Distribution Model, I showed that ladybirds aggregate in places with a prominent object and where the risk of being sprayed by pesticides is low. Then, I highlighted that abiotic conditions are unfavourable to ladybirds' survival. In a third part, I found that mating is widespread activity in the aggregation sites. Finally, I showed that energetic costs linked to mating are low, and thus allow the ladybirds to disperse and display post aggregations behaviour. This thesis shows that the diapause aggregations are part of the mating system of the arthropods and that sexual selection can be a driver of the evolution of diapause aggregations

Повний текст джерелаThe objective of this study was to characterize the floristic and phytosociological composition of the shrubby-arboreal component of four quintals agroforestry (QAs) in the Mariana resettlement, Tocantins, in order to know the structure of these areas and their contributions to the maintenance, protection and conservation of biodiversity. In addition, it was sought to subsidize the formation of a database of agroforestry quintals in the state of Tocantins. Three 20x30m plots were installed in each quintal, making a total of 0,72 ha of sample area, and all shrub-arboreal individuals with chest height circumference 1,30 cm (CAP) ≥ 10 cm were sampled. A total of 477 individuals, 81 species, 34 families and 73 genera were sampled in the four QAs. The value found for the diversity index (Shannon) was 3,68 and for equability (Pielou) was 0,83, values found in 0,72 ha of sample area.Individually, agroforestry quintals had the following Shannon diversity values (H '): QA1 2,52; QA2 3,27; QA3 2,66 and QA4 2,94; And Pielou equability (J ') QA1 0,78; QA2 0,90; QA3 0,77 and QA 40,85. The average height of the vegetation in QA 01 was 4,79m and total basal area was 120,17 m²/ ha, in QA 02 the average height was 5,14m with a total basal area of 18,49 m²/ ha, in QA 03 a mean height was 3,66 m and total basal area was 27,42 m²/ ha; in QA 04 the mean height was 5,54m with a total basal area of 33,98 m²/ha.The ten most important agroforestry species together represented 44.26% of the value of total importance, especially the species: Malpighia glabra, Psidium guajava and Mangifera indica that they reached prominent positions in more than one quintal.The ten most important families together accounted for 67.63% of the total IVI, and the families that stood out were Arecaceae, Anacardiaceae and Fabaceae for all (QAs) evaluated. Thus, it can be inferred that the agroforestry quintals of the Mariana resettlement demonstrated high richness and diversity, evidencing great environmental heterogeneity and low ecological dominance.
