Effects of Pesticides on Bombina bombina in Natural Pond Ecosystems

Appendix A

Table A.1:
Pesticides used on field(s) surrounding the ponds. Inaccurate dates are marked with (*). Where two fields surrounded one pond, the fields are indicated by roman numbers.

Brug af pesticider på mark(er) omkring vandhullerne. Upræcise datoer er markeret med (*). Hvor to marker omgav et vandhul er markerne angivet med romertal.

Table A.2
Supply of fertilizer for the growth season on fields surrounding ponds. Unknown amount of fertilizer supplied are indicated by (?). Where two fields surround one pond, the fields are indicated by roman numbers.

Tilførsel af gødning til marker omkring vandhullerne. Ukendt gødningsmængde er markeret med (?). Hvor to marker omgiver et vandhul, er markerne angivet med romer tal.

Grey cells indicates that the pond was not included in the investigation in 1993.

Table A.5
Yearly survival of Bombina bombina older than 1 year in Danish localities and degree of cultivation of the habitat. Ponds, moors, dry and wet permanent grasslands, hedgerows and woods are uncultivated areas. Agricultural areas are cultivated. Survival estimates were calculated over a number of years.

Årlig overlevelse af klokkefrøer ældre end 1 år på danske lokaliteter og dyrkningsgrad af habitaten. Vandhuller, moser, enge, overdrev, hegn og skov er udyrkede arealer, mens landbrugsarealer er dyrkede arealer. Overlevelsesestimater er udregnet som gennemsnit over flere år.

Table A.6
Predators in enclosures during hatching experiment. Number of predators indicated by: - none, + 1, ++ 2-5.

Prædatorer i bure under klækningseksperiment. Antal prædatorer er markeret ved: - ingen, + 1, ++ 2-5.

*A leach was observed swallowing a small tadpole.
In 1993-94 eggs were kept in bags with a mesh size of 1x1 mm. Leaches (Hirudinea) were able to get into these. In 1995 fine-meshed nylon bags were used instead. In P1 and P7 in 1995 a duplicate portion of eggs were kept in bags with mesh size 1x1 mm.

Grey cells indicate that the pond was not included in the investigation in 1993.

Table A.7
Predators in enclosures during tadpole growth experiment. Number of Dystiscidae and Odonata indicated by: - none, + 1, ++ 2-10. Number of Hirudinea indicated by: - none, + 1-10, ++ 11-20, +++ 21-50, ++++ >50.

Prædatorer i bure under haletudse eksperiment. Antal Dystiscidae og Odonata er markeret ved: - ingen, + 1, ++ 2-10. Antal Hirudinea er markeret ved: - ingen, + 1-10, ++ 11-20, +++ 21-50, ++++ >50.

Grey cells indicate that the pond was not included in the investigation in 1993.

*
+ = thin
++ = thick
+++ = very thick

**
0 = none
1 = few
2 = many

***
0 = none or very few
1 = few
2 = many

Grey cells indicate uncompleted registration of algae.
