Abstract Decades of agriculture in a former—type ecosystem, for example, deciduous forests—result severe habitat degradation. The planted tree species encounter harsh conditions due to physically and chemically transformed soil environments. In addition, afforestation itself significantly modifies the upper horizons. It may impact fauna communities, including mites from Mesostigmata order (Mesostigmata = Gamasida). Due their sensitivity, mesostigmatid are good bioindicators changes soil. A...

Next to global warming, excessive deposition of nitrogen has an alarming environmental impact on forest ecology, especially within dioecious species. Resource availability affects seed quality and can affect the distribution plant Lower productivity also be a result limited pollen or lower quality. A few studies have assessed effect nutrient quantity grains produced. Therefore, rooted shoots dioecious, male Juniperus communis L. grown in different nutritional conditions were used assess...

Abstract Key message We identified the effect of microclimatic conditions on soil mite communities (Mesostigmata) during decomposition broadleaved and coniferous litter. The abundance, species richness, diversity decreased from spring to autumn regardless litter quality was related changes in temperature precipitation. Context Litter is one fundamental soil-supporting processes terrestrial ecosystems. However, there still a lack knowledge some general patterns relationships between (tree...

Abstract • Key message Natural regeneration of P. abies (L.) H. Karst. may reach high densities in lower mountain elevations. The highest were found sites with moderate light availability, low pH, and not near the riverbank. However, age-height classes differed predicted magnitude response, but consistent response directions. Mosses understory species typical coniferous forests positively correlated density. Context Norway spruce Picea Central Europe is at risk under climate change...

Mites significantly contribute, prevalently by vertical movement, to mixing of the organic layer with mineral soil, thus they may be important in renewing soils. Our aim was analyze changes abundance and species richness mesostigmatid assemblages on decomposing leaves Alnus glutinosa (L.) Gaertn., Betula pendula Roth, Pinus sylvestris L. Quercus robur pine birch stands growing a reclaimed spoil heap adjacent forests. In December 2013, 1024 litterbags (mesh size = 1 mm) containing leaf litter...

Replacement of native deciduous forests by coniferous stands was a common result former European afforestation policies and paradigms forest management led to considerable ecological consequences. Therefore, the most popular strategy nowadays in multi-functional forestry is re-establishment mixed or broadleaved with species on suitable habitats. However, our knowledge about effects tree introduced into monocultures soil mesofauna communities scarce. We investigated abundance, richness...

This study determined the scale of phoresy mesostigmatid mite by Ips typographus.Thirty pheromone traps in Karkonosze National Park (Poland) caught 10,575 bark beetles on which there were 2,388 mites belonging to eight species.The most numerous Dendrolaelaps quadrisetus (1076 ind.) and Trichouropoda polytricha (1067 ind.).

Abstract Previous studies have suggested that forest management practices can influence bark beetle populations as well those of some associated insects. However, the impact on beetle-associated mites, which occur in galleries large numbers, not yet been studied. The objective this study was to compare mesostigmatid mite communities with Norway spruce pest Ips typographus managed and natural stands separated by spruce-free belt. sites were located Białowieża National Park (NE Poland) Izery...

Density, diversity and assemblage structure of Mesostigmata (cohorts Gamasina Uropodina) were investigated in Scots pine forests differing forest age (young: 9-40 years mature: 83-101 years) which wildfire occurred. This animal group belongs to the dominant acarine predators playing a crucial role soil food webs being important as biological control agents. In total, six (three within young three mature stands) inspected Puszcza Knyszyńska Forest Complex May 2015. At each area, sampling was...

During the nineteenth and twentieth centuries, coniferous monocultures were introduced, replacing natural broadleaved forests in Central Europe, mainly for economic benefits. In mountains, Norway spruce [Picea abies (L.) H. Karst] was introduced large areas previously covered with beech also riverside habitat corridors such as river valleys, despite its negative impact on soil environment by e.g. organic matter accumulation, decrease of pH changes C/N ratio. We aimed to check how long-term...

Although seed quality and quantity, as well reproductive performance are important life history stages of plants, little is known about the responses trees to environmental changes such increased anthropogenic deposition nitrogen (N) phosphorus (P). Dioecious plants good models with which test impact on female or male individually. We analysed effects different long-term nutritional availability two dioecious species (Taxus baccata L. Juniperus communis L.) characterised by histories. By...

The aim of the study was to explore phoretic relationships between Plagionotus detritus and mites from order Mesostigmata. In total, 635 individuals P. were caught, found on 86 them. dominant species among 8,154 Trichouropoda sociata (8,152 individuals), sporadically Lasioseius thermophilus (1 ind.) Typhlodromus sp. ind.). Generally, difference in total abundance females males not statistically significant (311 vs 324 males). proportional with T. differed samplings, pooled data, (39.5%) less...

Abstract We analyzed the changes in ecosystem functions (soil respiration and Mesostigmata mite abundance, species richness diversity) on various habitats after flooding by highly mineralized acidic drainage water with fine As‐rich pyrite sediments, a fragment of natural ecosystem. In total, 177 plots that represented six types (undisturbed: pine mixed forests, Salix spp. thickets, Juncus effusus communities, wet meadows, disturbed: bare ground dead thickets) were sampled twice, June 2019...

Spring areas are specific habitats characterized by higher humidity, which favors the presence of a range living organisms. We have studied three types mountain forest springs (<i>Piceo-Alnetum, Carici remotae-Fraxinetum, and Equiseto sylvatici-Piceetum abietis</i> communities) Stołowe Mountains National Park (Poland), focusing on species diversity lichens bryophytes. In terms cryptogam species, exhibit large pool shared species. This similarity is most notable between...

Abstract Post-agricultural land differs from typical forest in physical, chemical and biological features. In addition, the environment of this type is determined, among other things, by introduced tree species. These differences may be revealed biodiversity abundance soil fauna. We analysed abundance, species richness diversity different instars mesostigmatid mites inhabiting three habitat types on post-agricultural (shaped pure Pinus sylvestris L., Tilia cordata Mill. Betula pendula Roth...

Soil mites (Acari, Mesostigmata) from Szczeliniec Wielki in the Stołowe Mountains National Park (SW Poland) The species composition of mesostigmatid soil and leaf litter was studied on plateau, which is spatially isolated similar rocky habitats. A total 1080 samples were taken June 2004 to September 2005. samples, including organic horizon herb layer rock cracks, collected using steel cylinders (area 40 cm 2 , depth 0-10 cm). They generally dominated by Gamasellus montanus, Veigaia...

Coarse woody debris (CWD) is a basic component of forest ecosystems and it plays crucial role in species-poor boreal forests. Generally, previous studies have focused on differences between the floor decaying logs various tree species. The impact distance to CWD has been investigated mainly for forest-floor snails some groups macrofauna, but not yet mesostigmatid mites communities. We hypothesized that effect decreases with increasing from CWD. To test this hypothesis we conducted study...

Abstract. A new species Arctoseius wisniewskii sp. nov. (Acari: Ascidae) is described and illustrated. It was found in litter soil from rock cracks the Gory Stolowe National Park Poland.

Afforestation can make an important contribution mitigating the effects of changing climate and provide structural functional benefits. also provides challenges for forest managers connected with past land-use history; therefore, there is urgent need to summarize knowledge about such habitats point out gaps in planning future studies. Although post-agricultural forests cover a large area Europe, our understanding mechanisms governing below-ground environment still poor, especially when soil...
