- Description:
- Water-lilies (the genus Nymphaea) are one of the most ancient groups of aquatic plants. Two species (N. alba and N. candida) are native to the flora of the Czech Republic, both are critically endangered. Morphological similarities, large phenotypic variation and putative interspecific hybridization pose difficulties for species identification. The amount of nuclear DNA was found to be a reliable characteristic that allows not only species but also their hybrids to be re - cognized. Native species are mainly threa - tened by the loss of suitable habitats and planting of garden cultivars in natural sites. and Klára Kabátová, Petr Vít, Jan Suda.

- Description:
- A new species of the genus Lemuralges Fain, 1963 (Acariformes: Psoroptidae: Makialginae) is described from the Malagasy lemur Propithecus diadema (Bennett) (Primates: Indriidae) based on all postembryonic instars. This new species differs from the only known species in this genus, Lemuralges intermedius Fain, 1963, by the following features: both sexes of L. propithecus sp. n. show a pair of medioventral projections of the subcapitulum (vs without projections in L. intermedius) and the propodonotal shield is slightly ornamented (vs unornamented); in males the hysteronotal shield is completely covered by longitudinal striae (vs median part without striae), setae c2 are 120-140 µm long (vs 200-210 µm long), and femur III has a short transverse furrow dorsally (vs a longitudinal furrow); in females, setae h2 are, at least, 2 times shorter than h3 (vs slightly longer, or subequal to, h3), tibia IV has a ventro-apical projection (vs without projection). Larvae and protonymphs of the new species show some unique developmental delays. Female and male tritonymphs differ by their external morphology., Andre V. Bochkov, Hans Klompen, Randall E.

- Language:
- English
- Description:
- The aim of our in vitro studies was to understand the role of leptin in controlling proliferation, apoptosis, and protein kinase A (PKA) in human ovarian cells. We analyzed the in vitro effects of leptin (0, 1, 10 or 100 ng/ml) on the accumulation of proliferation-related peptides (PCNA, cyclin B1), apoptosis-associated peptide (Bax) and the intracellular signaling molecule PKA in cultured human granulosa cells using immunocytochemistry and Western immunoblotting. It was observed that leptin stimulated in a dose-dependent manner the accumulation of PCNA (at doses 1-100 ng/ml), cyclin B1 (at doses 10 or 100 ng/ml), Bax (at doses 10 or 100 ng/ml) and PKA (at doses 1-100 ng/ml) in cultured human ovarian cells. These observations suggest the ability of leptin to control directly human ovarian cell functions: proliferation, apoptosis, and intracellular messenger PKA., A. V. Sirotkin, M. Mlynček, A. V.

- Description:
- A cyanobacterium containing phycobiliproteins with far-red acclimation was isolated from Pozas Rojas, Cuatro Ciénegas, México. It was named Leptolyngbya CCM 4 after phylogenetic analysis and a description of its morphological characteristics. Leptolyngbya was grown in far-red light. Sucrose-gradient analysis of the pigments revealed two different colored bands of phycobiliproteins. A band at 60% sucrose was a phycocyanin containing phycobilisome; at 35% sucrose, a new type of phycobiliprotein absorbed at 710 nm. SDS-PAGE revealed the presence of two types of core-membrane linkers. Analysis of the hydrophobic pigments extracted from the thylakoid membranes revealed Chl a, d, and f. The ratio of Chl f/a was reversibly changed from 1:12-16 under far-red light to an undetectable concentration of Chl f under white light. Cuatro Ciénegas, a place surrounded by the desert, is a new ecosystem where a cyanobacterium, which grows in farred light, was discovered., C. Gómez-Lojero, L. E. Leyva-Castillo, P.

- Description:
- The Southern Urals are an inspiring place for Czech naturalists. This paper provides basic information on this seldom visited region and describes the impressions of the two Czech biologists from their excursion to this place. The nature of the Southern Urals captivated them with its wildness, unrivalled in present-day Central Europe, its intrinsic order and the similarities with Central European nature. and Jan Roleček, Jan Losík.

- Language:

- Description:
- Charakter krajiny je v oblasti centrálních Apenin již na první pohled výrazně různorodý. Dynamicky formovaný reliéf pokrývá pestrá mozaika vegetačních typů. Zdejší lesy jsou od dávných dob obhospodařované pařezinovým způsobem, což je typ managementu, který byl na území bývalého Československa běžný až do minulého století. Typicky šlo o dubové a dubohabrové lesy, jejichž biodiverzita dlouhodbě klesá. Návštěva a studium lesů centrálních Apenin poskytuje hodnotné souvislosti pro řešení problému klesající druhové diverzity v někdejších pařezinách střední Evropy., The landscape of the central Apennines is markedly diverse. Dynamically formed relief is covered by a mosaic of different vegetation types. For centuries, local forests are managed as coppices - type of management common in former Czechoslovakia up to last century. Biodiversity of these oak and oak-hornbeam forests gradually declines due to the abandonment of coppicing. Thus, a visit to the central Apennines and study of their forests provide a valuable insight into the problem of species diversity decline in the former coppices of Central Europe., and František Máliš, Roberto Canullo, Radim Hédl.
