“…In t�ese models, t�e s�are of soil CO 2 in cave CO 2 levels varied between 38 and 69%. Doubts about t�e dominant role of soils in cave CO 2 resonate wit� some aut�ors (Miotke 1974;Bárány-Kevei 1999;Tatár et al 2004;Baldini et al 2005). Even if t�e soil CO 2 effect was superimposed by ant�ropogenic CO 2 in t�is study, alternative sources (e.g.…”

Vse spremenljivke kažejo podobne letne trende in so med seboj korelirane. Do-Dokazali smo povezavo med koncentracijo CO2 ter temperaturo in vlago v prsti. Posamezne vplive zaradi multikolinearnosti nismo mogli izločiti. Vpliva vegetacije na produkcijo CO Vpliva vegetacije na produkcijo CO2 v prsti nismo zaznali. Prisotnost ljudi v jami se je izkazal za najpomembnejši prediktor vrednosti CO2. Druge spremenljivke, kot Druge spremenljivke, kot so CO2 v prsti in temperaturni gradienti so se izkazale za manj pomembne.

Variations of soil/cave CO 2 concentrations and furt�er variables suc� as temperature, �umidity, and cave visitor attendance were studied in two sites of t�e Moravian Karst (Czec� Republic). All t�e variables s�owed t�e same seasonality; t�ey were strongly correlated wit� eac� ot�er. The dependence of soil CO 2 levels on soil air temperature and absolute �umidity was confirmed. Individual effects could not be distinguis�ed because of multicollinearity. The effect of vegetation on soil CO 2 production was not recognized. Cave attendance was identified as t�e most significant predictor of cave CO 2 levels. Ot�er variables, soil CO 2 and temperature gradients, were less significant. A spurious relations�ip was alternatively considered, in w�ic� external temperature was t�e universal predictor of cave CO 2 levels.

“…Therefore, CO 2 transfer between the soil and cave is affected by the external environment (Angel et al, 2015). On the one hand, hydrothermal conditions influence biological action to control CO 2 formation (Tatár et al, 2004), while on the other hand, the amount of infiltration water controls the hydrogeochemical water-soil-rock process (Yuan, 1995;White, 2013;Pu et al, 2018). Thus, soil CO 2 is considered to be an important CO 2 source for cave systems (Fairchild et al, 2006;Faimon et al, 2012).…”

Study on vertical migration of CO₂ in a karst cave system

CO 2 is an important driving force in karstification. Studying the variation characteristics of CO 2 in each zone of a karst cave system during different seasons might contribute to revealing its migration path and to further exploring CO 2 sources in caves. To this end, we monitored the soil, cave drip water, and cave air CO 2 in Mahuang Cave, SW China. We analyzed the vertical migration characteristics of CO 2 based on the carbonic acid equilibrium system theory and the stable isotopes of carbon through statistical analysis. The results show the following: (1) There are obvious seasonal changes in CO 2 in each zone of Mahuang Cave, generally indicating high rainy season and low dry season characteristics. (2) The CO 2 in Mahuang Cave is mainly supplied by the soil, bedrock, and the external atmosphere. The rainy season has plentiful rainfall, and the CO 2 in the cave is mainly derived from soil CO 2 . In the dry season, with lower temperature and little rain, cave CO 2 is mainly attributed to the external atmosphere, brought by the ventilation effect, and carbon in the bedrock. (3) Carbonate precipitation in Mahuang Cave is dominant throughout the year. The seepage migration process and carbonate precipitation are controlled by the soil "CO 2 effect" and drip water type.

“…Pode-se observar o acumulação de detritos ocasionados pelo escorregamento, reforçado por alto declive (> 60º), uma área com solo fértil, geralmente cortado por um curso d´água, com o estabelecimento de um ambiente florestal (TATAR et al, 2004). Nesses ambientes, o microclima formado pela geomorfologia somado às condições edáficas do Cerrado, podem ser os fatores decisivos para produção de serapilheira (ACOSTA et al, 2008).…”

RESUMO:A serapilheira acumulada sobre o solo das florestas tem papel importante na dinâmica desses ecossistemas, pois a maior parcela da energia que flui no sistema está concentrada nesse compartimento. Objetivou-se, neste estudo, quantificar e analisar a serapilheira formada abaixo do dossel da Floresta de Galeria e Mesofítica, presentes na Dolina da Garapa-DF, relacionando-a com variáveis meteorológicas e ecofisiológicas, buscando verificar diferenças significativas entre estes dois ambientes florestais e entre os meses de estudo. De janeiro de 2006 a dezembro de 2007, foram dispostos 50 coletores de serapilheira em cada ambiente florestal, em que foi coletada, pesada e classificada a serapilheira em folhas, caule e galhos, flores, frutos e sementes. Os valores médios encontrados de produção de serapilheira em massa total de folhas, flores e caules, galhos, frutos e sementes, foram diferentes significativamente nos dois ambientes estudados. Na correlação entre as variáveis meteorológicas e ecofisiológias e o valor de serapilheira registrado, observou-se, que apenas a variável temperatura não obteve significância do coeficiente de correlação ( < 0,5) para produção de serapilheira. Pela produção total de serapilheira durante o período estudado mostrou-se que a Floresta Mesofítica é a mais vulnerável a fatores externos meteorológicos e a fatores ecofisiológicos de suas espécies, do que a Floresta de Galeria. Primeiro pelo fator espacial, a localização da Floresta de Galeria, em baixa altitude, não está exposta a fatores meteorológicos (por exemplo, radiação solar) como a Floresta Mesofítica, e segundo pela proximidade do curso d´água. Esse fator espacial e a menor influência dos fatores meteorológicos mantiveram a produção de serapilheira total com um menor desvio médio na Floresta de Galeria em uma escala temporal, sendo que a Floresta Mesofítica ficou susceptível a variações sazonais meteorológicas, tendo assim um maior desvio médio da produção de serapilheira, ao longo do período estudado.Palavras-chave: Fenologia, índice de área foliar, abertura de dossel, pluviosidade. LITTERFALL PRODUCTION IN GALLERY AND MESOPHYTIC FOREST, IN GARAPA DOLINE, FEDERAL DISTRICT, BRAZIL ABSTRACT: The accumulated litterfall on the soil of forests has an important role in the dynamics of these ecosystems, because the high portion of energy flowing in the system is concentrated in this compartment. The objective this work was to quantify and analyze the litterfall got understory of the Gallery and Mesophytic Forests present in the Dolina
