Books and other publications that oppose feminism have difficulties being published. This is exemplified by cases from North America, Britain, Germany, Denmark and Sweden. Books criticizing feminism often have to be published by their author´s own publishing company, or as print-on-demand by personal contact to their author. Even if they, in spite...

Terrestrial gastropods in managed and unmanaged Danish forests.

In Denmark, nature conservation in the middle of the twentieth century mainly involved protecting areas by legal declarations forbidding the destruction or degradation of the protected area. During the period 1946 to 1969, 22 sites with fire-bellied toads Bombina bombina were protected as single ponds, and 40 ponds with Bombina were protected as a...

1) N added to decomposing organic matter often has no effect or a negative effect on microbial activity, at least in the long term. More than 60 papers are cited in support of this statement. (2) The negative effect of N is mainly found with recalcitrant organic matter with a high C/N ratio (straw, wood, etc.), whereas a positive effect of N is com...

All-hybrid populations of the water frog, Rana esculenta, are exceptional in consisting of independently and to some extent sexually reproducing interspecific hybrids. In most of its range R. esculenta reproduces hemiclonally with one of the parental species, R. lessonae or R. ridibunda, but viable populations of diploid and triploid hybrids, in wh...

A genetic study of the European tree frog, Hyla arborea, in Denmark was undertaken to examine the population structure on mainland Jutland and the island of Lolland after a period of reduction in suitable habitat and population sizes. The two regions have experienced the same rate of habitat loss but fragmentation has been more severe on Lolland. G...

Pond projects for the benefit of rare amphibians in Denmark were undertaken on a large scale from 1986 onwards. The paper presents data on nearly 3 500 ponds made or modified for amphibians, of which ca. 2 000 were aimed specifically at rare species. More than half of the projects consisted of making new ponds, more than a third undertook the dredg...

Summary In the Wadden Sea, in total, 8 species of amphibians and 4 species of reptiles are threatened in at least one subregion. Of these, 7 species of amphibians and all 4 species of reptiles are threatened in the entire area and are therefore placed on the trilateral Red List. 1 species of the listed reptiles is (probably) extinct in the entire W...

By sampling of water frogs on Bornholm in 1992, Rana ridibunda was found to have declined since 1949, but was still widely distributed. Rana ridibunda from Bornholm tends to deviate from central European R. ridibunda in certain morphological traits. The green frogs of Bornholm show many different, interesting mating systems, especially a system wit...

Of 15 fire-bellied toad localities known in 1974, 7 have now disappeared. The few large populations all seem to be slowly declining. Active management to save the species has been carried out in some places since 1982. Establishment of a few new localities has been attempted. -Authors
