1. According to the preference-performance hypothesis, female insects select resources that maximize offspring performance. To achieve high fitness, leaf miner females should then adjust their oviposition behaviour in response to leaf attributes signalling high host quality. 2. Here we investigate resource selection in Tischeria ekebladella, a leaf-mining moth of the pedunculate oak (Quercus ro...

The aim of this study is to investigate the effects of two important factors: light and water availability on the leaf characteristics and the growth of plants. Seedlings of Quercus suber were grown under controlled conditions (greenhouse) with three light treatments (100, 27 and 3 % of incident light, open, shade and deep shade; respectively) and with daily irrigation. Since middle spring, one...

The long-term increases in average temperature and intensification of droughts which characterise the current state Earth’s climate system have a negative impact on forest ecosystems can lead to decrease their area deterioration living conditions components. In Ukrainian Steppe an important environmental, antierosion, water-protective soil-protective role belongs ravine forests. most valuable c...

Seasonal drought can severely impact leaf photosynthetic capacity. This is particularly important for Mediterranean forests, where precipitation is expected to decrease as a consequence of climate change. Impacts of increased drought on the photosynthetic capacity of the evergreen Quercus ilex were studied for two years in a mature forest submitted to long-term throughfall exclusion. Gas exchan...

The prediction of leaf area for cherrybark oak (eerm pagoda Raf.) seedlings is important for studying the physiology of the species. Linear and polynomial models involving leaf length, width, fresh weight, dry weight, and internodal length were tested independently and collectively to predict leaf area. Twenty-nine cherrybark oak seedlings were grown in a greenhouse for one growing season and a...

The simple leaves of deciduous forest trees in temperate zones have more irregular and asymmetric shapes than comparable non-deciduous the tropics subtropics. These manifest as lobes sinuses species Quercus Acer, well greater bilateral asymmetry Ulmaceae Betulaceae, serrated margins many species, frequency compound generally (Fraxinus Carya). modifications may contribute to an early transition ...

Urban areas with trees provide several ecosystem services to citizens. There is a growing interest in for the removal of air pollutants such as particulate matter. The objective this paper show study on variation intercepted matter concentration (IPMC) by tree leaves megacity Bogotá (Colombia). relationship between IPMC and PM2.5 concentrations observed quality stations two urban zones differen...
