Supersymmetric orientifolds of four dimensional Gepner Models are constructed in a systematic way. For all levels of the Gepner model being odd the generic expression for both the A-type and the B-type Klein bottle amplitude is derived. The appearing massless tadpoles are canceled by introducing appropriate boundary states of Recknagel/Schomerus(RS). After determining the Möbius strip amplitude...

We analyze a model of conflict with endogenous choice of effort, where subsets of the contenders may force the resolution to be sequential: First the alliance fights it out with the rest and – in case they win – later they fight it out among themselves. For three-player games, we find that it will not be in the interest of any two of them to form an alliance. We obtain this result under two dif...

Schellackia calotesi n. sp. is described from the Thai agamids Calotes mystaceus and C. versicolor. Schellackia-type sporozoites were recovered from blood and liver of one C. versicolor from Kon Kaen North-East Thailand and two C. mystaceus from Chiang Mai, North Thailand. Specimens of both species were fed on sporozoite infected blood, of these only one C. mystaceus developed endogenous infect...

Two new species of the genus Tillicera Spinola, 1841 from China are described and illustrated: Tillicera sensibilissp. n. from Yunnan (also from Myanmar, Thailand and Laos) and Tillicera weniisp. n. from Taiwan. Tillicera bibalteata Gorham, 1892, Tillicera hirsuta (Pic, 1926) and Tillicera michaeli Gerstmeier & Bernhard, 2010 are newly recorded from China. Tillicera auratofasciata (Pic, 1927) i...

We investigated the ecology and life strategy of Glaucomides bromelicola (family Bromeliophryidae), a very common ciliate in the reservoirs (tanks) of bromeliads, assessing its response to food quality and quantity and pH. Further, we conducted competition experiments with the frequently coexisting species Bromeliothrix metopoides (family Colpodidae). In contrast to B. metopoides and many other...

In this paper, we describe a new species of the genus Allonychiurus Yoshii, 1995, characterized by the presence of an apical swelling on the fourth antennal segment as well as a combination of chaetotaxic and pseudocellar characters. The genus Allonychiurus is redefined. Four of its species are considered as incertae sedis: Allonychiurus michelbacheri (Bagnall, 1948), Allonychiurus spinosus (Ba...
