Cell size may be important in understanding the thermal biology of ectotherms, as the regulation and consequences of cell size appear to be temperature dependent. Using a recently developed model system of triploid zebrafish (which have around 1.5-fold larger cells than their diploid counterparts) we examine the effects of cell size on gene express...

Genetic variation is often lower at high latitudes, which may compromise the adaptability and hence survival of organisms. Here we show that genetic variability is negatively correlated with northern latitude in European green toads (Bufotes viridis). The result holds true for both putatively neutral microsatellite variation and supposedly adaptive...
Being composed of small cells may carry energetic costs related to maintaining ionic gradients across cell membranes as well as benefits related to diffusive oxygen uptake. Here we test the hypothesis that these costs and benefits of cell size in ectotherms are temperature dependent. To study the consequences of cell size for whole-organism metabol...
Habitat restoration is a mitigation tool often proposed in conservation biology, however, our knowledge about
its effectiveness is still limited. Here we evaluate the effects of a large-scale drainage and habitat restoration project on the amphibian community in the Narew River Valley, Poland. We used visual encounter surveys, manual calling survey...
In multicellular organisms, cell size may have crucial consequences for basic parameters, such as body size and whole-body metabolic rate (MR). The hypothesis predicts that animals composed of smaller cells (a higher membrane surface–to–cell volume ratio) should have a higher mass-specific MR because a large part of their energy is used to maintain...
Previous studies reported that low temperatures result in increases in both cell size and body size in ectotherms that may explain patterns of geographic variation of their body size across latitudinal ranges. Also, polyploidy showed the same effect on body size in invertebrates. In vertebrates, despite their having larger cells, no clear effect of...
The aim of this research was to analyse the mortality rate of vertebrates caused by vehicular traffic on 27.5-kilometer section of the Tsar’s Road in Biebrza National Park. Plant communities occurring along the road was classified into six categories. During three surveys conducted in spring, summer and autumn in 2014, a total of 5283 vertebrates w...
Type of reproduction has an important effect on the maintenance of particular populations and species persistence in time and space. This trait significantly influences the ecological and genetic structure of populations, and in consequence the evolution of species. The primary objectives of this study were: to estimate genetic diversity within and...
We describe a pentaploid froglet (LLLRR; three Pelophylax lessonaeand two Pelophylax ridibundusgenomes) that has never been reported before within the Water Frog Pelophylax esculentus)hybrid complexes. The pentaploid specimen was found among almost all triploid siblings obtained from a
diploid femaleP. esculentus(LR) crossed with a diploid male P....
This paper is a result of research carried out in the Suwałki Landscape Park
in the years 1998 – 2004. During the inventory, 113 water reservoirs were penetrated and all
the found amphibians were caught and released after determining the species and sex. Eleven
species of amphibians were found in the Park’s area and the most numerous were: smoot...
Research was carried out in the area of the Romincka Forest Landscape
Park (RFLP) in the years 2001 – 2003. The species composition of the amphibians was
determined0 in 173 water reservoirs. Amphibians were present in all of them but only in 138
their reproduction was observed. In this study 9638 individuals of amphibians belonging
to 10 specie...
A large decline of amphibians is observed in the world so monitoring sites of
their occurrence seems to be particularly important. This paper is a result of research carried
out in the Iława Lakeland Landscape Park (ILLP) in the years 2000 – 2002. During three
seasons 246 water reservoirs (including 18 lakes) were penetrated and 5372 amphibians...
