Extant and fossil genera and species in the Libytheinae (Nymphalidae) are revised and reviewed. The Libytheinae includes two genera: Libythea Fabricius and Libytheana Michener. Fifteen species and an additional 24 subspecies are recognized and 41 names are synonymized. Species recognized are: Libythea celtis (Laicharting), L. collenettei Riley, L. cinyras Trimen revised status, L. geoffroyi God...

A major development over the past two decades has been the realization that free radical induced lipid peroxidation and DNA damage are associated with major health problems, e.g. cancer and ageing. Plant-derived antioxidants are increasingly found beneficial in protecting against these diseases. Celtis australis L. and Celtis occidentalis L. are two plants that have a variety of uses in folk me...

The introduced tree, Sapium sebiferum, is a serious invader throughout the southeastern United States. Low herbivore loads, commonly attributed to high herbivore resistance, are assumed to give Sapium a competitive advantage over native vegetation. Because herbivory resistance is considered energetically expensive, we predicted that if Sapium experienced higher levels of damage its growth would...

The antioxidant activities of the methanol extracts from the leaves and stems of Celtis africana (Ulmaceae) were assessed in an effort to validate the medicinal potential of the subterranean part of the herb. The antioxidant activity and phenolic contents of the stem as determined by the DPPH, proanthocyanidins, total phenols, the flavonoids, and total flavonols were higher than that of the lea...

the endocarp of celtis australis l. with hyrcanian forests of northern iran and arid mountains of northern africa ecotypes were studied considering macro and micro morphologic characteristics, using binocular and scanning electron microscope. the aim of this research was to evaluate the endocarp diversity in different ecological conditions. the results showed that celtis australis l. is bigger,...

1 The first trees establishing in grasslands may indirectly favour their seedlings in competition with neighbouring herbaceous vegetation by increasing soil fertility with nitrogen-rich litter and by reducing light levels under their canopies. It is predicted that increasing soil nitrogen availability will accelerate invasion of trees by stimulating their growth more than that of herbaceous spe...
