To date, half (16 of 32) of the species of Ameerega have had their tadpoles described: A. altamazonica, A. bassleri, A. bilinguis, A. braccata, A. cainarachi, A. flavopicta, A. hahneli, A. macero, A. parvula, A. petersi, A. picta, A. rubriventris, A shihuemoy. A. silverstonei, A. smaragdina, and A. trivittata (Lescure, 1976; Silverstone, 1976; Duellman, 1978; Myers & Daly, 1979; Rodriguez & Myers, 1993; Haddad & Martins, 1994; Lötters et al., 1997; Duellman, 2005; Costa et al., 2006; Twomey & Brown, 2008; Brown & Twomey, 2009; Poelman et al., 2010; Schulze et al., 2015). Ameerega boehmei is a putative member of a clade containing Ameerega braccata, A. flavopicta, A. berohoka, A. munduruku, all of which inhabit various parts of the ‘dry diagonal’ between the Amazon and Atlantic rainforests (Prado & Gibbs, 1993). Adult frogs in this group are morphologically similar, generally dark-bodied with yellow dorsolateral stripes, orange flash marks and some also possessing bright-yellow dorsal spots. Despite considerable research on their breeding behavior, acoustics and systematics (Lötters et al., 2009; Forti et al., 2013), the tadpole of Ameerega boehmei, the southern-most and western-most distributed species in this tentative group, has not been described.

AbstractAlthough considerable research has been devoted to cognitive functions deteriorating due to diseases of cardiovascular system, rather less attention has been paid to their theoretical background. Progressive vascular disorders as hypertension, atherosclerosis and carotid artery stenosis generate most of all pathological changes in the white matter, that cause specific cognitive disorder: disconnection syndromes, and disturbances in the dynamic aspect of information processing. These features made neuropsychological disorders secondary to cardiovascular diseases different than the effects of cerebral cortex damage, which may be interpreted modularly.

This article presents a frank and open opinion on the challenges that will be faced in moving towards an electric mass transport ecosystem. World over there is considerable research activity on electric vehicles and hybrid electric vehicles. There seems to be a global effort to move from an ICE driven ecosystem to electric vehicle ecosystem. There is no simple means to make this transition. This road is filled with hurdles and challenges. This paper poses and discusses these challenges and possible solutions for enabling EVs.

The archetypal shrub type that dominates most of the regions that experience mediterranean-type climate (MTC) is an evergreen shrub with thick and leathery leaves (sclerophyllous). The occurrence of large stands of such shrubs in all MTC regions led early biogeographers to hypothesize that the MTC selects for this growth form and leaf type and that this had led to convergent evolution (see Chapters 1 and 2). This hypothesis has received considerable research interest and continues to be examined. In this chapter we consider the structure and physiology of these archetypal MTC region shrub species and examine evidence for convergent evolution in their structure and function. We also assess the key adaptive traits that enable the shrub species that compose mediterranean-type vegetation (MTV) communities to thrive in MTC regions.
