The Conservation Ecology of Rana temporaria and Bufo bufo in Leicestershire
… vegetation in field ponds as small as 35 m3, but Bufo bufo only in ponds over 100 m3, in areas where scrub vegetation cover exceeded 2.5% of the total area. The densities of all ponds and R. temporaria and B. bufo breeding ponds have been reduced at the rates of 2.6, 1.3 and 0.7 per km per 10 …

The environmental physiology of Bufo bufo L. and Bufo calamita Laur. tadpoles.
… development, metabolism and metamorphosis in B. bufo and B. calamita tadpoles were investigated, together with a limited study on the effects of L-thyroxine. The effects of density on growth, developteI1t and metamorphosis were examined. Physiological and behavioural effects of B. bufo tadpoles …

Back to the future? Unravelling current and potential future declines of the common toad, Bufo bufo, in the UK
… and unexplained declines of the common toad, Bufo bufo, have been recorded in the UK for over two decades, especially in southern and central England. However, the extent of these declines and their causes are poorly understood. Except for “toad patrols” taking place in many parts of the UK, …

A sensory system for robots using evolutionary artificial neural networks.
… sensory-motor connections in the common toad, Bufo Bufo. The sparsely connected network architecture has features of modularity enhanced by the presence of lateral inhibitory connections. It was implemented using Evolutionary Artificial Neural Networks (EANN). A novel method called FUSION was …

The drivers of variation in susceptibility to the amphibian-killing fungus, batrachochytrium dendrobatidis
… set of mainland and isolated island common toad (Bufo bufo) populations situated on the edge of their range in northwest Scotland.Microsatellites were used to characterise patterns of genetic variability across eleven populations. It was found that seawater serves to isolate demes, producing high …

Using eDNA to construct community assemblages of amphibians at sites infected with Batrachochytrium salamandrivorans in the Netherlands.
… present at a site in Gelderland, Netherlands. Bufo bufo, Lissotriton vulgaris, Pelobates fuscus, Pelophylax spp. and Rana temporaria were detected by both the 12S-V5 vertebrate and the 16S amphibian universal primer sets used in this study with the 12S-V5 primers also detecting Triturus …

The plasticity of life histories during larval development and metamorphosis, using amphibians as study organisms.
… in development was observed in the lung-less Bufo bufo tadpoles. The results of these studies did not allow a definitive assessment of whether over-wintering as larvae represents an adaptive strategy or occurs as the result of developmental constraints. There is some evidence that …
