Lepeophtheirus simplex Ho, Gómez et Fajer-Avila, 2001 is a parasite of Sphoeroides annulatus (Jenyns), an economically important fish species, with potential for aquaculture, in northwestern Mexico. The goal of this study was to describe the developmental stages under experimental conditions and seasonal fecundity of this parasite on wild fish. There are two naupliar, one copepodid, two chalimus and two pre-adult stages preceding the adult of L. simplex. The results support previous findings, which point out that the life cycle of the caligid copepods includes only six post-naupliar stages. The generation time from egg extrusion to adult for L. simplex was approximately 10 days at 22 °C. The body length of the ovigerous females ranged between 2.2 and 4.1 mm, and its fecundity between 12 and 36 eggs per string. Fecundity was negatively correlated with the egg size and positively correlated with the egg string length. Our data did not reveal significant differences in fecundity among sampling months, but ovigerous females were significantly larger in March (when water temperature was 22 °C) than in June and July (when water temperature was 30 °C). To some extent, our fecundity results contrast with those found in species of sea lice from higher latitudes. Undoubtedly, biological information on different species of sea lice from different environmental conditions will enhance our understanding of their infection strategies and will be valuable, given the increasing interest in marine fish farming in Mexico., Francisco Neptalí Morales-Serna, Ana Inés Rivas-Salas, Samuel Gómez, Emma Josefina Fajer-Ávila., and Obsahuje bibliografii
This article presents the little known diary entries of the priest P. Václav Vojtěch Berenklau († 1699) primarily from the Kladruby period of his activities (1675-1677). An attempt is also made to compare his diary with a fragment from 1662-1663 of a priest's diary belonging to P. Jan Manner in Prague and the as yet largely unexamined diary specimens from the famous P. Bartoloměj Michal Zelenka from the time he was active in Brandýs nad Labem. In addition to these diaries, the diary is also compared with notes made by the distinguished Baroque preacher and writer O. F. De Waldt.

Stať se zaměřuje na zkoumání příčin rostoucí mimomanželské plodnosti. Vychází z dat výzkumného šetření Sociální a ekonomické podmínky mateřství (SEPM) provedeného v roce 2006 v Sociologickém ústavu AV ČR. Tato data umožňují na mikroúrovni poodkrýt důvody, jakými neprovdané matky vysvětlovaly svoji vlastní rodinnou situaci při narození prvního dítěte. Analýza identifikovala tři typy motivací neprovdaných matek: nesouhlas/ absence partnera, liberální postoje a pragmatické (ekonomické) důvody. Jednotlivé skupiny neprovdaných matek se lišily nejen postoji k manželství, ale i tím, jak vnímaly budoucnost vztahu s otcem dítěte. Příslušnost k jednotlivým skupinám souvisela s tím, jestli žena v době narození prvního dítěte žila v nesezdaném soužití s jeho otcem, s výší vzdělání a jejím věkem při narození prvního dítěte. Skupiny neprovdaných matek mají navíc rozdílné vyhlídky do dalšího rodinného života. V druhé části se příspěvek zaměřuje na to, jaké partnerské uspořádání považují neprovdané matky za ideální. Data SEPM ukazují, že velká část neprovdaných matek preferuje manželský svazek po předcházejícím nesezdaném soužití.
This contribution deals with the manuscripts of the Wrocław University Library, in which works by the English reformer John Wyclif († 1384) are recorded. It shows that besides one known manuscript dating from the second half of the 15th century, Sg. IV F 7, and containing the work De universalibus, there are two copies of Wyclifˇs letter to the pope Urban VI (in the manuscripts dating from the first half of the 15th century, Sg. I F 594 and I F 707), and that in the former of the manuscripts mentioned a text dealing with the preparation for taking the Eucharist is recorded too, which otherwise survives in two Viennese manuscripts and is an item of the list of Wyclif´s works regarded as dubium. Moreover, the article mentions two Wyclifi an spuria (Sg. I F 733 and I F 570). All these copies came into being as marginalia of the reception of Wyclif´s work in Bohemia.
