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 ...

The relationship between climatic conditions and generative reproduction of a lowland population of Pulsatilla vernalis: the last breath of a relict plant or a fluctuating cycle of regeneration?

The alpine-boreal plants which have survived in Central European lowlands during glacial periods depend both on the preservation of their refugial habitat, and their capability for vegetative and generative reproduction and dispersion. Pulsatilla vernalis (L.) Mill. is a model species which occurs throughout most of the European alpine system, as well as in isolated populations in ...
