introduction: antioxidants are compounds that eliminate free radicals, which reduce tissue damage and allow the organs and blood vessels to properly heal. in this research, the anticancer effect against mcf-7 and ht-29 cell lines, and antioxidant, antimicrobial and wound healing activities of the lichens extracts have been investigated. materials and methods: anticancer activity was assayed wit...

Between 1850 and 1950, hundreds of lecideoid lichen-forming fungi were described from Fennoscandia, mainly in the genus Lecidea. The status many these species is still uncertain some have not been revised since their description. We examined types nomenclature nine such taxa, found that they represent synonyms earlier species: Bacidia dolera (= Lecidea albofuscescens), aviaria Rhizocarpon richa...

High adult mortality rate is expected to select for early maturation. However, physiological constraints or size-related reproductive benefits might select for delayed maturation, especially in small-bodied species. Additionally, the mating system and the relative intensity of mate competition can modify the timing of maturation. Here, we investigate the influence of mortality rate and mating s...

Populations at range limits are often characterized by lower genetic diversity, increased genetic isolation and differentiation relative to populations at the core of geographical ranges. Furthermore, it is increasingly recognized that populations situated at range limits might be the result of human introductions rather than natural dispersal. It is therefore important to document the origin a...

Life-history theory predicts that small species will exhibit short life-spans and fast growth rates; however, previous studies indicate that a positive relationship between size and maximum age may not be universally applicable to coral reef fishes. Here, we investigate the growth and life-span of 5 small species of coral reef goby (family Gobiidae): Istigobius goldmanni, Asterropteryx semipunc...

Abstract Arthonia epipolytropa Hafellner & Grube and subclemens Hafellner, Muggia are described as new to science. Both specific parasites of Lecanora polytropa s. lat., but differing pathogenicity very different appearance. Whereas the clearly parasitic with its agglomerated ascomata is presently known certainty from a number localities along arch Alps (Austria, Italy, Switzerland), other ...
