Conifer regeneration failure in the presence of dense ericaceous cover resulting from removal canopy trees by forest harvesting observed boreal and temperate has been attributed to allelopathy, competition, soil nutrient imbalance. Ecosystem-level alleopathic effect argued as a cause for conifer citing examples species-poor northern Sweden with ground vegetation dominated crowberry (Empetrum hermaphroditum, Ericales) New Zealand dairy pastures invaded nodding or musk thistle (Carduus...
Understanding disturbance effects on species diversity and functional is fundamental to conservation planning but remains elusive. We quantified richness, diversity, evenness of riparian upland plants along 24 small streams subjected a range anthropogenic disturbances in the boreal forest northwestern Ontario, Canada. included total 36 traits related productivity, competitive ability, reproduction, tolerance, life history, tolerance habitat instability. Using nested ANOVA, we examined...
Summary Although anthropogenic edges are an important consequence of timber harvesting, due to natural disturbances or landscape heterogeneity also common. Forest have been well studied in temperate and tropical forests, but less so productive, disturbance‐adapted boreal forests. We synthesized data on forest vegetation at forests compared edge influence among types (fire, cut, lake/wetland; old vs. young), (broadleaf coniferous) geographic regions. Our objectives were quantify responses all...
The relationship between species diversity and functional is a fundamental topic in conservation ecology but its direct evaluation naturally heterogeneous systems with disturbance intensity limited. We examined the taxonomy-based (in terms of richness evenness) trait-based riparian upland vegetation determined if slopes this vary intensity. used data from plant communities subjected to three categorical intensities (low = uncut mature forests, intermediate buffers around clearcuts + soil...
Tropical and subtropical karst forests of south China are under increasing pressure from over-exploitation causing widespread habitat degradation biodiversity loss. Previous research has demonstrated that topography, as a proxy for resource availability, plays an important role in shaping tree species distributions tropical forests. However, the association between growth stages habitats types not been considered this analysis. Our aim was to examine differences among different determine...
Although riparian buffers are an important aspect of forest management in the boreal Canada, little is known about habitat conditions within buffers, due part to complex edge effects response both upland clearcut and stream. We investigated microclimatic bryophyte growth vitality seven locations between stream 60 m into undisturbed conifer forests at sites with buffer 30 km northwest Thunder Bay, Ontario, Canada. hypothesized that a pleurocarpous moss, Hylocomium splendens, acrocarpous...
(1) Estimates were made of seed production, dispersal and storage in the soil Calluna-Arctostaphylos heath N.E. Scotland. Germination seedling establishment recently burned areas also studied. (2) Seed production by individual species found to follow abundance each stand, though performance some declined as Calluna canopy closed. Little input occurred from surrounding into closed or stands. (3) The amount stored varied according stand age. Seeds vulgaris Carexpilulifera increased with Stored...
Predicting the relationships between disturbance, biodiversity and productivity of ecosystems continue to preoccupy ecologists resource managers. Two hypotheses underpin many discussions. The Intermediate Disturbance Hypothesis (IDH), which proposes that peaks at intermediate levels is often extended predict follows same response pattern. Mass Ratio (MRH) biological traits dominant species are critical drivers ecosystem function (e.g., productivity) these increase in biomass rapidly after...
Abstract Considering intraspecific trait variability (ITV) in ecological studies has improved our understanding of species persistence and coexistence. These advances are based on the growing number leaf ITV over local gradients, but logistical constraints have prevented a solid examination root traits or at scales reflecting species’ geographic ranges. We compared magnitude above‐ below‐ground plant organs across three spatial (biophysical region, locality plot). focused six understorey...
Karst areas in Southwest China, with Guizhou as the focal center, are confronted ecological deterioration and large of rocky desertification. Human activities defined driving force behind soil erosion. Further, local farmers area suffer from poverty due to a lack drinking water, food weak living environment. Over one-third national poverty-stricken counties occur this part China. To balance protection economic development region help out we propose integrated controls discuss on ground water...
