Interaction between invasive and potentially invasive shrub species does not influence relationships between their ecological success and distance from propagule sources

Although interactions between alien and native plant species are well studied, data on interactions between two co-existing alien species with respect to their invasibility are scarce. The aims of this study were (1) to evaluate three factors shaping abundance of the alien shrub species Cornus alternifolia: abundance of another alien (invasive) shrub species (Prunus serotina), type ...

The age of restoration: challenges presented by dryland systems

Intact drylands are highly evolved and complex ecosystems, which allow them to be productive despite harsh environmental conditions. However, drylands are particularly susceptible to degradation, even after minor disturbance events. Conditions for natural plant recruitment in dryland systems are spatially and temporally irregular, which can create challenges for restoration. ...

Differential impact of hotter drought on seedling performance of five ecologically distinct pine species

Increasing temperature and drought intensity is inducing the phenomenon of the so-called “hotter drought”, which is expected to increase in frequency over the coming decades across many areas of the globe, and is expected to have major implications for forest systems. Consequences of hotter drought could be especially relevant for closely related species overlapping their ...

Plant ecology meets animal cognition: impacts of animal memory on seed dispersal

We propose that an understanding of animal learning and memory is critical to predicting the impacts of animals on plant populations through processes such as seed dispersal, pollination and herbivory. Focussing on endozoochory, we review the evidence that animal memory plays a role in seed dispersal, and present a model which allows us to explore the fundamental consequences of ...

Land-use change under a warming climate facilitated upslope expansion of Himalayan silver fir (Abies spectabilis (D. Don) Spach)

Global warming is triggering some species to shift towards the poles or higher elevations, but spatial translocation is also influenced by land-use regime or intensity. The Himalayan climate is getting warmer and land use has changed, reducing in intensity in some areas. We estimated the upper species limit (USL) and tree limit of Abies spectabilis (D. Don) Spach and assessed ...

Age-related decomposition of Quercus mongolica branches

Litter decomposition is a critical process for the maintenance of terrestrial ecosystems. Although large quantities of organic matter and nutrients are supplied by branch litter, its decomposition has received little attention. In this study, we focused on Quercus mongolica, one of the most common temperate deciduous woody species in the Northern Hemisphere, to investigate the ...

Advances in understanding the influence of fire on the ecology and evolution of plants: a tribute to Peter J. Clarke

In this special issue of Plant Ecology celebrating the research contributions of the late Peter J. Clarke, we review advances in understanding of interactions between fire and vegetation, and the role of these interactions in shaping the evolution of plant species. The research presented here reviews the measurement of fire severity and plant responses to it, particularly through ...

Historical contingency and spatial processes rather than ecological niche differentiation explain the distribution of invasive goldenrods (Solidago and Euthamia)

The effectiveness of invasion depends on the interacting environmental factors and biology of the invader. The effects of these interactions are contingent on their contexts and difficult to predict. Among the most successful plant invaders in Europe are the goldenrods (Solidago and Euthamia genera). We assessed the roles of ecological niche differentiation and historical ...

Changes in foliar litter decomposition of woody plants with elevation across an alpine forest–tundra ecotone in eastern Tibet Plateau

To determine litter decomposition rates at different elevations in the alpine forest–tundra ecotone under climate change scenarios in which woody plants shift their ranges upward, litterbags containing foliar litter were incubated on the surface of forest, tree line, and alpine meadow soils (3900, 4000, and 4200 m above sea level, respectively) in the eastern Tibet Plateau of China ...

Successful translocation of the threatened New Zealand root-holoparasite Dactylanthus taylorii (Mystropetalaceae)

The conservation and translocation of threatened holoparasitic flowering plants provide added challenges due to their complete host dependency and often large knowledge gaps of their autecology. Here, we present the first successful, quantified field trial to establish from seed populations of dactylanthus (Dactylanthus taylorii, Mystropetalaceae), a threatened New Zealand endemic ...

Large pollen at high temperature: an adaptation to increased competition on the stigma?

Pollen availability is a major constraint of plant reproductive success. Because pollen size trades-off with the quantity of produced grains, the link between climate characteristics and the determination of pollen size is of fundamental importance. To minimize the rate of water loss due to desiccation, a plant should produce larger grains that also have a lower surface-to-volume ...

Regional variation in Caribbean dry forest tree species composition

How does tree species composition vary in relation to geographical and environmental gradients in a globally rare tropical/subtropical broadleaf dry forest community in the Caribbean? We analyzed data from 153 Forest Inventory and Analysis (FIA) plots from Puerto Rico and the U.S. Virgin Islands (USVI), along with 42 plots that we sampled in the Bahamian Archipelago (on Abaco and ...

Phylogenetic gradient analysis: environmental drivers of phylogenetic variation across ecological communities

Differences in species composition across ecological communities are the result of multiple interacting mechanisms. Gradient analysis has been perhaps the most widely used statistical framework in describing how ecological communities vary in space, and aiding in determining the causes underlying these patterns. Direct gradient analysis allows the use of predictors such as ...

Season of fire manipulates bud bank dynamics in northern mixed-grass prairie

In perennial grassland dominated systems, belowground bud banks regulate plant community dynamics. Plant community responses to disturbance are largely driven by the ability to generate future aboveground growth originating from belowground axillary buds. This study examined bud bank dynamics for Bouteloua gracilis, Hesperostipa comata, and Pascopyrum smithii following fire in ...

Topics in constrained and unconstrained ordination

In this paper, we reflect on a number of aspects of ordination methods: how should absences be treated in ordination and how do model-based methods, including Gaussian ordination and methods using generalized linear models, relate to the usual least-squares (eigenvector) methods based on (log−) transformed data. We defend detrended correspondence analysis by theoretical arguments ...

Principal component analysis with missing values: a comparative survey of methods

Principal component analysis (PCA) is a standard technique to summarize the main structures of a data table containing the measurements of several quantitative variables for a number of individuals. Here, we study the case where some of the data values are missing and propose a review of methods which accommodate PCA to missing data. In plant ecology, this statistical challenge ...

Heat tolerance of early developmental stages of glacier foreland species in the growth chamber and in the field

In glacier forelands, seeds readily germinate, however, a high proportion of seedlings die shortly after their appearance. We hypothesized that besides drought, frost and missing safe sites, heat on the ground surface could be one of the major threats for seedlings. The heat strain in different ground strata was assessed from 2007 to 2010. The heat tolerance (LT50) of eleven alpine ...

Living with extremes: the dark side of global climate change

We are pleased to announce a new special issue of Plant Ecology on extreme weather events.The new report of IPCC (2013) predicts remarkable increase in global mean air temperatures. Depending on the scenarios, the best estimates of temperature increase range from 1.8 and 4.0 °C by 2100. Climate change may generally act in two ways: gradual warming will affect plants and vegetation ...
