Streszczenie:

The eyes are the most important sensory organs for most vertebrates. Their structure and development is conserved between several vertebrate species. The development is regulated by several signalling pathways, including the Wnt/β-catenin signalling pathway. It is required for several aspects of retinal development and it is known to regulate the proliferation of neuro-epithelial stem cells. In Xenopus laevis the intracellular Wnt/β-catenin signalling pathway is activated in the retina by the Wnt receptor Fz5. Fz5 function in the eye was shown to regulate tissue specific gene expression and ne

Amphibians have been facing global declines over the last decades due to direct and indirect effects of anthropogenic activities. One of the leading causes is environmental contamination, particularly that of waterbodies which are used by many amphibian species for reproduction, development, and adult life. An important source of contamination comes from agricultural runoffs of pesticides such as neonicotinoids, which are known to alter anuran survival, behaviour, predation stress response, and development. However, few studies have investigated the possible interactions between neonicotinoids

This thesis examines the applicability of pre-dominantly Western theories of inclusive school development in countries of the Global South. Firstly, the findings of a review of research literature are used to develop a typology to describe the common features of inclusive schools, incorporating ways in which they might be supported. This typology was then used to explore the ways in which schools in the Lao People's Democratic Republic and Thailand developed inclusive practices. Engagement with school systems in these countries over a period of six years between 2003 and 2009 provided opportun

The causes and consequences of variation in aposematic signals during immature stages are not clearly understood. This thesis explores the effects of early environment on the expression of aposematic signals in the green and black poison frog (Dendrobates auratus), and the consequences of variation in such components in the wild. It also explores how aposematic expression relates to levels of chemical defences in immature froglets. Embryos and larvae of poison frogs in the genus Dendrobates are known to be darkly pigmented.

Environmental stressors are ubiquitous. Animals will face a variety of natural and anthropogenic stressors throughout their life cycle. The physiological mechanisms that mediate stressful stimuli can have pleiotropic effects on life history traits, such as reproduction and development. Furthermore, these phenotypic changes can affect larger-scale ecosystem dynamics, like nutrient cycling and disease epizootics. Animals are not equally susceptible to stressors across all stages of their life cycles. Critical windows of development, common in young and developing animals, are time periods when s

My thesis has accomplished 3 significant contributions to neuroscience. Firstly, I have discovered a novel example of vertebrate deep-brain photoreception. Spontaneously generated fictive locomotion from the isolated nervous system of pro-metamorphic Xenopus tadpoles is sensitive to the ambient light conditions, despite input from the classical photoreceptive tissues of the retina and pineal complex being absent. The photosensitivity is found to be tuned to short wavelength UV light and is localised to a small region of the caudal diencephalon. Within this region, I have discovered a populatio

The desmosome is one of the major cell adhesion junctions found in the epithelia, heart, and hair follicle. Described as a “rivet” that hold cells together, it provides these tissues with the integrity to withstand the tremendous forces they face in everyday life. Defects in this junction can lead to devastating diseases where patients are susceptible to skin infections and cardiovascular defects. Limited treatments exist for diseases of the desmosome, and strategies do not target all symptoms. Therefore, delineating the function and regulation of desmosomes is of paramount importance for the

The effects of TCS on metamorphosis were also investigated. For 0-week tadpoles, LC50 values for TCS and TCC were 0.87 mg/L and 4.22 mg/L, respectively, and both compounds caused a significant stunting of growth. For 4-week tadpoles, the LC50 values for TCS and TCC were 0.22 mg/L and 0.066 mg/L; and for 8-week tadpoles, the LC50 values were 0.46 mg

Telling a story to a naïve listener places varied demands on a speaker. As the story plot develops, the speaker must set and re-set these parameters for referring to characters, as well as the temporal and spatial parameters of the story. To these cognitive and linguistic tasks is the added social and pragmatic task of monitoring the knowledge and attention states of their listener.

<p>Assembling a nervous system requires exquisite specificity in the construction of neuronal connectivity. One method by which such specificity is implemented is the presence of chemical cues within the tissues, differentiating one region from another, and the presence of receptors for those cues on the surface of neurons and their axons that are navigating within this cellular environment.</p> <p>Connections from one part of the nervous system to another often take the form of a topographic mapping. One widely studied model system that involves such a mapping is the vertebrate retin

Streszczenie:

Cannibalism is a seemingly aberrant interaction, appearing counter to the fitness of individuals. Yet cannibalism is not overly uncommon, and naturally occurs among aquatic organisms, including larval amphibians. In temporary wetlands larval amphibians are in a race to complete metamorphosis before their aquatic habitat disappears. When intraspecific competition intensifies, eating conspecifics may represent a beneficial if not necessary strategy. The research presented within this thesis aims to characterize factors that influence cannibalism within populations of larval amphibians. Wood frog
