A comparison between models describing the influence of temperature on the development rate of copepods OMA
Heip, C.H.R..
Four mathematical expressions relating development time to temperature are compared. All four yield good predictions of the development rate of the copepod <i>Tachidius discipes</i>. The use of the equation of Belehradek is criticized. It is concluded that the power equation D= aT<sup>b</sup> gives the best approximation in this case.

A cytological investigation of flowering plants from the Canary Islands Naturalis
Loon, J.Chr. van.
The chromosome numbers of 85 species of flowering plants from the Canary Islands were determined; 5 of the counts turned out to be new. Notes on some species are given. Numbers deviating from previous counts proved to occur in Polycarpaea divaricata (Pit.) Poir. and Koeleria phleoides (Vill.) Pers. 49 counts are new for the Canary Islands and are listed in table 2.

A MICROECONOMIC APPROACH TO INDUCED INNOVATION AgEcon
Binswanger, Hans P..
Invention possibilities are reformulated using research processes which have a cost and different implications for rates and biases of technical change. In the comparative static model a firm has the choice to build a plant of existing design or to improve it by research. The firm maximizes present value over the lifetime of the plant. Research costs and present value of capital and labor costs influence research mix and rate and bias to technical change. Controversies in the literature of induced innovation are discussed in terms of the model. A rise in labor costs does not necessarily lead to a more labor saving bias.

A new index measuring evenness OMA
Heip, C.H.R..
A new evenness index based on the Shannon-Wiener information <i>H</i> is defined as (<i>e<sup>H</sup></i> -1)/(<i>S</i> -1). This index is theoretically superior to other evenness indices and has a better statistical behaviour.

A new species of Alloeotomus Fieber (Heteroptera, Miridae, Deraeocorinae) from Cyprus Naturalis
Önder, F..
Introduction Recently I had the occasion to examine a collection of 230 unidentified specimens of the family Miridae kindly loaned to me for examination by the Rijksmuseum van Natuurlijke Historie, Leiden, Netherlands. All these were collected in Cyprus. Three specimens belong to the genus Alloeotomus Fieber and represent a new species which is described here. Until now the southernmost limits of the distribution of Alloeotomus were Sicily (Wagner, 1954) in the west and Peking (China) (Reuter, 1903) in the east. The discovery of the new species from Cyprus has extended this limit further to the south. There are now five species in the genus Alloeotomus including the new one. A key to facilitate their identification is given in this paper. Alloeotomus...

A new species of anostomid characoid fish, Anostomus spiloclistron, from the Nickerie river system of western Surinam (Pisces, Cypriniformes, Anostomidae) Naturalis
Winterbottom, Richard.
A new species of the anostomid characoid genus Anostomus is described from the Nickerie river system of western Surinam. The new species appears to be most closely related to A. plicatus Eigenmann, 1912, from the Essequibo river system of Guyana. Diagnostic features include the number of lateral line scales, the number of midventral scales between the pelvis and the anus, certain proportional measurements, and differences in the colour pattern.

A new species of Paeonodes (Therodamasidae, Cyclopoida), a parasitic copepod of the fish Tilapia melanotheron from the Sakumo-lagoon, Ghana, Africa Naturalis
Banning, Paul van.
A new species of the genus Paeonodes Wilson, 1944 (Therodamasidae, Cyclopoida, Copepoda), P. lagunaris, is described from Tilapia melanotheron Rüppel, 1852, of the Sakumo-lagoon, Ghana, Africa. The new species is compared with the hitherto known two species of the genus Paeonodes and the relationship of the genus with euryhaline waters is discussed.

A note on the life-span of r-strategists OMA
Heip, C.H.R..
The idea is presented that the short life-span of <i>r</i>-strategists may in some cases be an adaptation to avoid predation. Evidence supporting this hypothesis is presented by examination of predation of the polyp <i>Protohydra leuckarti</i> on harpacticoid copepods.
