In 2007, the population of Feral Pigeons in Gdańsk City (almost 500,000 inhabitants) constituted 14 200 individuals. The population density in the built-up areas of Gdańsk (82.2 km²) was estimated at an average of 17.2 birds 10⁻¹ ha, however the highest density occurred in Gdańsk’s city centre area (5.7 km²) – 44 birds 10⁻¹ ha. Blue plumage type pigeons dominated in the population (93%), while black, red and albinotic types were rarely observed. Melanistic birds were more frequently found than blue-bar birds, whose plumage is inherited from the Rock Pigeon. However, blue-bars were more numerous in Gdańsk compared with other pigeon populations in central and northern Europe. Old pre-war buildings were not confirmed as influencing the plumage pattern of pigeons. Melanistic birds were more numerous in old district of Oliwa, whereas blue bars in old Gdańsk city centre. The plumage of pigeons in small flocks of up to 50 birds did not differ from that of pigeons in flocks of over 50 and 100 birds. Blue-bars, checkers and dark checkers did not differ in body mass or breeding parameters. Other causes of polymorphism variation among pigeons in a population are discussed.

Polymorphisms in mitochondrial DNA (mtDNA) were analyzed in 152 samples from the Polish population using restriction enzymes AvaI, BamHI, HaeII, HpaI and PstI. Additionally, each sample was classified into the appropriate haplogroup. When required, appropriate fragments were sequenced to establish the exact poly­morphic sites. We found one new morph for PstI and six new morphs for AvaII. Some detected morphs have previously been described as population specific morphs in different regions of the world. All polymorphisms were classified into 31 different haplotypes. 21 of them were detected in single individuals. The Polish population was compared with other populations from different regions. Moreover, we have ob­tained evidence for mutation hot spots in the mtDNA coding region. Our results indi­cate that AvaII morph and haplogroup composition of the Polish population is simi­lar to other European populations and has a distribution typical for this part of the world. However, statistically significant differences in haplogroup composition were found between the Polish population and Italian and Finnish populations.

The morphs of green apple aphid occurring on apple host in Himachal Pradesh, which is the main apple growing state of India, were ascertained and their life history was studied on the apple nursery plants from 2002 to 2006 in Mashobra locality (3101'N latitude, 7701'E longitude and altitude 2286 m above sea level) of Shimla district and Ner Chowk locality (31032'N latitude, 76054'E longitude and altitude 878 m above sea level) of Mandi district of Himachal Pradesh. Only two kinds of parthenogenetic morphs i.e. apterous and alate parthenogenetic viviparous females occur in this state. Biological characteristics, life history and behaviour of these morphs were studied in different seasons Heavy infestations of green apple aphid prevent the terminal growth of the plants which show distorted growth. This aphid pest builds up big colonies on twigs, leaf petioles and the underside of the leaves. Its settling behaviour on apple plants allows accommodating large number of aphids in a small area on shoots and leaves. Maximum alate morphs were produced from May to August and number of alates was also more in crowded colonies. The alate aphids infest new plants and build up new colonies there. The populations of this insect pest increase in early May and reach high peaks in July. The effect of aphids’ feeding on the growth of nursery plants was also measured.

Basal metabolic rate (BMR) of the European pine vole Pitymys subterraneus (de Sélys-Longchamps, 1836) with typical black agouti coat colour (A) is 2.78 cc O2 g"1 hr" , and in voles with diluted fur pigment (D) it is 3.06 cc O2 g"1 hr"1. The difference of BMR between the voles of A and D morphs is not significant. Resting metabolic rate (RMR) was determined at ambient temperatures (Ta) -10°C, 0°C, 6°C, 12°C, 24°C and 30°C. P. subterraneus of A morph decrease RMR from 9.21 (at -10°C) to 4.80 cc O2 g"1 hr 1 (at 30°C) while the voles of D morph decrease RMR from 10.43 to 4.01 cc O2 g"1 hr'1, respectively. The differences of RMR between the voles of A and D morphs are significant at Ta -10°C, 0°C, 6°C, 24°C, and 30°C. Maximum oxygen consumption rate (VO2NA), after injection of noradrenaline, is not dependent on Ta (measurements were made at -10°C, 0°C, 12°C and 24°C). It equals 8.96 cc 02 g"1 hr"1 in P. sub­terraneus of A morph and 10.18 cc O2 g"1 hr"1 in the voles of D morph, and the difference is significant.
