Regenerating forelimbs of larval salamanders, Amblystoma punctatum, were fixed in OsO(4) at various intervals after amputation and were sectioned for study with the electron microscope. The dedifferentiated cells comprising the early blastema were found to have a fine structure similar to that of other undifferentiated cells and to have lost all of the identifying morphological features of thei...

Insect pests are responsible for substantial damage to museum objects, historic books and in buildings like palaces or historic houses. Different wood boring beetles (Anobium punctatum, Hylotrupes bajulus, Lyctus sp. or introduced species), the biscuit beetle (Stegobium paniceum), the cigarette beetle (Lasioderma serricorne), different Dermestides (Attagenus sp., Anthrenus sp., Dermestes sp., T...

The subfamily Plectorhinchinae (sweetlips) is composed of poorly-known species with high commercially and ecologically values that exhibit phenotypic plasticity various morphologies. Few studies have assessed the validity sweetlips, intergeneric relationships evolutionary survey in this subfamily, which not yet been resolved. This study investigated DNA sequences (1) mitochondrial COI gene to d...

In the previous paper of this series (Remp, '53) it was reported that tadpoles of Rana pipiens would live up to 6 days at room temperature after excision of heart at Shumway stage 22 or 23. Because of the obvious differences between anuran and urodele larvae in form and rate of development, the experiment was repeated on Amblystoma punctatum at Harrison stage 40, 41 o r 42 (Kemp and Quinn, '51)...

The landscape (matrix) surrounding habitat fragments critically aVects the biodiversity of those fragments due to biotic interchange and physical eVects. However, to date, there have been only a limited number of studies on plant– animal interactions in fragmented landscapes, particularly on how tree seedling herbivory is aVected by fragmentation. We have examined this question in a fog-depende...

INTRODUCTION Eruptive pseudoangiomatosis consists in the acute development of small vascular lesions in the face and extremities that resolve in several weeks without scarring. Lesions are described as 3-4 mm asymptomatic macules and papules with peripheral whitish halo that blanch upon pressure. Initially it was considered a disease limited to children but it has also been described in adults....

The wood-inhabiting fungi play an integral role in wood degradation and the cycle of matter ecological system. They are considered as “key player” decomposition, because their ability to produce all kinds enzymes that break down woody lignin, cellulose hemicellulose. In present study, three new fungal species, Steccherinum fissurutum , S. punctatum subtropicum spp. nov., collected from southern...
