Abstract:
... In 2016, a storm blew over an old growth sand post oak tree (Quercus margarettae) at O'Leno State Park in northern Florida. This event provided access to the entire tree without climbing it. Because the tree was suspended by its branches so it was parallel with the ground, we could easily observe and collect lichens at all former canopy heights. We surveyed the wind-blown tree's lichens before the ...

Abstract:
... The main components of the annual water and nutrient balance are determined for the basin of the Kud’ma River, which has a landscape structure typical of the southern part of the forest zone. The contribution of the natural and anthropogenic factors to nutrient inputs into the Kud’ma River and their export from the catchment area is estimated. It is shown that forest tree waste is among the major ...

Abstract:
... How populations of long‐living species respond to climate change depends on phenotypic plasticity and local adaptation processes. Marginal populations are expected to have lags in adaptation (i.e. differences between the climatic optimum that maximizes population fitness and the local climate) because they receive pre‐adapted alleles from core populations preventing them from reaching a local opti ...

Several ophiostomatoid species were reported already from Rapanea melanophloeos of the Afromontane forests from the Cape Floristic Region (CFR) of South Africa. The aim of this study was to investigate the diversity of ophiostomatoid fungi associated with wounds on other Afromont ...

For temperate forests, Michigan, USA, we asked: (1) does evidence exist for a height-dependent sapling recruitment bottleneck caused by shrub layer competition and white-tailed deer (Odocoileus virginianus) browsing and, if so, (2) how do these factors interact with light availability in shaping species-specific sapling recruitment niches? The combination of deer browsing effects on tree populatio ...

Abstract:
... Some temperate tree species are associated with very low soil nitrification rates, with important implications for forest N dynamics, presumably due to their potential for biological nitrification inhibition (BNI). However, evidence for BNI in forest ecosystems is scarce so far and the nitrifier groups controlled by BNI‐tree species have not been identified. Here, we evaluated how some tree specie ...

Abstract:
... Both ozone (O₃) and drought can limit carbon fixation by forest trees. To cope with drought stress, plants have isohydric or anisohydric water use strategies. Ozone enters plant tissues through stomata. Therefore, stomatal closure can be interpreted as avoidance to O₃ stress. Here, we applied an optimization model of stomata involving water, CO₂, and O₃ flux to test whether isohydric and anisohydr ...

Abstract:
... Flying squirrels (genus Glaucomys) have a close association with forest trees for food, shelter, and travel. They play a key role in dispersing seeds and fungi, as well as being an important food source for predators. Thus, understanding their habitat requirements provides insight for conservation efforts, particularly in highly fragmented areas. This study employed radio-telemetry to examine habi ...

After the felling of such forests, the inherent populations are lost and cannot be replaced. In a project wit ...

Abstract:
... Scatter-hoarder birds can play a key role in the dispersal and recruitment of forest tree species through caching seeds, but accurate evaluation of their importance in this respect would require detailed monitoring of post-dispersal seed fate. To quantify seed fate under wild conditions researchers often use visual marks to locate the seed caches. However, the effect that these marks may have on s ...

Abstract:
... Oaks are dominant forest tree species widely distributed across the Northern Hemisphere, where they constitute natural resources of economic, ecological, social and historical value. Hybridisation and adaptive introgression have long been thought to be major drivers of their ecological success.

Abstract:
... Spring phenology of temperate trees has advanced worldwide in response to global warming. However, increasing temperatures may not necessarily lead to further phenological advance, especially in the warmer latitudes because of insufficient chilling and/or shorter day length. Determining the start of the forcing phase, that is, when buds are able to respond to warmer temperatures in spring, is ther ...
