Long-term nitrogen deposition reduces the diversity of nitrogen-fixing plants.

Biological nitrogen fixation is a fundamental part of ecosystem functioning. Anthropogenic nitrogen deposition and climate change may, however, limit the competitive advantage of nitrogen-fixing plants, leading to reduced relative diversity of nitrogen-fixing plants. Yet, assessments of changes of nitrogen-fixing plant long-term community diversity are rare.

Directional turnover towards larger-ranged plants over time and across habitats.

Species turnover is ubiquitous. However, it remains unknown whether certain types of species are consistently gained or lost across different habitats. Here, we analysed the trajectories of 1827 plant species over time intervals of up to 78 years at 141 sites across mountain summits, forests, and lowland grasslands in Europe.

Response to Comment on "Forest microclimate dynamics drive plant responses to warming".

Schall and Heinrichs question our interpretation that the climatic debt in understory plant communities is locally modulated by canopy buffering. However, our results clearly show that the discrepancy between microclimate warming rates and thermophilization rates is highest in forests where canopy cover was reduced, which suggests that the need for communities to respond to warming is highest in those forests.

Response to Comment on "Forest microclimate dynamics drive plant responses to warming".

Bertrand question our interpretation about warming effects on the thermophilization in forest plant communities and propose an alternative way to analyze climatic debt. We show that microclimate warming is a better predictor than macroclimate warming for studying forest plant community responses to warming. Their additional analyses do not affect or change our interpretations and conclusions.

Forest microclimate dynamics drive plant responses to warming.

Climate warming is causing a shift in biological communities in favor of warm-affinity species (i.e., thermophilization).

[Ileal duplication: challenging differential diagnosis caused by a rare abnormality. Case report].

Gastrointestinal tract duplications (GSD) are rare congenital abnormalities. Eighty percent of GSDs are diagnosed before the age of two. These lesions can be seen anywhere from the oral cavity to the anus, but ileum is the most commonly affected site.

Influence of human impacts on trace metal accumulation in soils of two Hungarian cities.

Despite the advanced activity of urban soil research, comparison of available trace metal contents in the soil of settlements has not yet been well investigated. First aim of research was the comparison of human impacts on urban soils in two Hungarian cities with different structure and development. To detect the sources of contamination, Szombathely and Sopron cities were separated into urban, suburban and peri-urban areas.

Long-term effects of climate change on carbon storage and tree species composition in a dry deciduous forest.

Forest vegetation and soils have been suggested as potentially important sinks for carbon (C) with appropriate management and thus are implicated as effective tools in stabilizing climate even with increasing anthropogenic release of CO . Drought, however, which is often predicted to increase in models of future climate change, may limit net primary productio (NPP) of dry forest types, with unknown effects on soil C storage. We studied C dynamics of a deciduous temperate forest of Hungary that has been subject to significant decreases in precipitation and increases in temperature in recent decades.

[Abdominal trans-sphincter resection of the anus: new possibilities in the surgical management of deep rectal cancer, with preservation of the anal sphincter].

The last decade has brought marked changes in the surgical treatment of rectal cancer: as the indication of the sphincter-saving procedures was extended, the rate of the abdomino-perineal excision has decreased even in the case of tumours of the distal third of the rectum. However, even with the use of the modern stapling devices, the anterior resection and colo-anal anastomosis may not always be feasible by the traditional abdominal approach. In these cases the sphincter-saving resection can be performed by a particular approach, the abdomino-transsphincteric technique.
