Butterflies fauna biodiversity in the post-mining landscape
(Wydawnictwa AGH, 2011) Čermáková, Zuzana; Pecharová, Emilie; Martiš, Miroslav
In this research we study butterflies diversity and abundance in North Czech Coal Basin (NCCB) and Landscape protected area Ceske stredohori (LP A). Butterflies are very sensitive species for changes in aricultural management (Denis 2004). They can be used as bioindicators and umbrella species. We study 4 localities - each of them includes 3 study plots. Two localities are situated in LPA and two are situated at dumps of (NCCB). We compare three different succesion stages (low xerotherm grassland, mezophilus grassland, areas with trees and bushes) on two different types of landscape (seminatural biotops x reclamations). In 2009 there were done four observations on each locality and two visits were done in 2010. Higher number of species was found in LPA and also more of rare and endangered species were observed there compare to dumps. Altough dumps seem to be good potential habitats for butterflies. Important for all localities is, if there is an active antropogenic management or not.

Preliminary studies on the protecting possibilities of selected small water bodies in the area of Krakow agglomeration
(2013) Panek, Ewa; Rajpolt, Bogusława
The studies were carried out in the western part of the Krakow agglomeration: the quarters of IV Prądnik Biały, VII Zwierzyniec and VIII Dębniki and the commune of Zabierzów. Seven sites were selected, according to the following criteria: the origin, size, characteristic of the adjacent area and vegetation as well as the degree of the preservation of the object. The studies included the ecological inventory of the sites, carried out by the established criteria and chemical analyses or waters. The following parameters were analysed: pH, specific conductivity, the content of macro-components: Na+, K+, Ca2+, Mg2+, HCO3-, Cl-, SO42- and general mineralization as well as the content of oxygen. Six objects are natural small water bodies, situated in urbanized areas, agricultural of forest areas. In six sites the lowering of the water mirror and/or expansion of emerged vegetation were observed, which can lead to their disappearance. Small objects are particularly sensitive to degradation and liquidation and require protective measures.

Rock mining industry in history. Geosites and geological and engineering assessment thereof
(2012) Pinińska, Joanna; Domonik, Andrzej
Historyczny rozwój Doliny Wisły związany jest z historycznym górnictwem skalnym. Region jest unikalnym przykładem zależności regionalnej architektury i sztuki dekoracyjnej od uwarunkowań geologicznych. Historia górnictwa sięga czasów paleolitycznych, kiedy pozyskiwano krzemienie i wykorzystywano je do wyrobu prostych narzędzi i broni. Prehistoryczni rzemieślnicy znający właściwości mechaniczne oraz posiadający umiejętność obróbki twardych krzemieni stali się prekursorami współczesnej geomechaniki. Z kolei dostępność skał węglanowych wywarła duży wpływ na budownictwo w regionie. Siedziby obronne, budynki sakralne, pałace oraz zwykłe budynki mieszkalne stawiano z użyciem białych opok, gez i wapieni. W XIX wieku region lubelski stał się pionierem przemysłu cementowego. Artykuł przedstawia w ogólnym zarysie geomechaniczną ocenę odsłonięć historycznych surowców skalnych - geostanowisk. Szczególną uwagę zwrócono na podatność skał na deteriorację i na długotrwałą stateczność zboczy oraz masywu skalnego. Kompleksową geomechaniczną ocenę geostanowiska przedstawiono na przykładzie odsłonięcia w Bochotnicy.

Właściwości geomechaniczne opok
(Wydawnictwa AGH, 2008) Pinińska, Joanna
The Lublin Region represents unusual example of co-existence of mining, building industry and rock workings,. The roots of today's industries in the Lublin Region reach as far back as Medieval times and even farther back - the Paleolithe. Cherts from chalky limestones in the river Vistula Valley, until the beginning of Iron Age, were basic supply for the various tools and weaponry. Prehistoric artisans, knowing the mechanical properties of chert bearing rocks and knowing how to mechanically processing hard cherts, become precursors of today's geomechanics. Availability of common carbonate rocks of the Upper Cretaceous and Neogene made significant impact on building industry. The defense heavy fortresses, sacral monumental buildings, and magnificent residential and common buildings are typically made of white, chalky and siliceous limestone blocks all over the Lublin Area. In the paper are outlined geological aspects and geomechanical assessment of the special, regional rock building material resources in the Lublin Region - the siliceous limestone, their geomechanical properties, which became the base of traditional building industry. Under special consideration is the vulnerability of siliceous rocks to physical deterioration with the passage of time. The description of typical forms of destruction of stony building elements is completing the paper.
