A heuristic approach to attenuation of non-relevant metabolites in groundwater and drinking water in GermanyNARA Subscribed
A simple and effective heuristic approach was developed and validated to predict the concentration of non-relevant metabolites (nrM) of pesticides in groundwater and drinking water resources based on the simulated concentrations in leachate as used in product authorizations. The evaluation of extensive monitoring data for 50 nrM has demonstrated that the heuristic has a high predictive performance, i.e., concentrations of < 10...
As multiple global sustainability crises are getting more severe and existential, a better understanding of how people undergo deep personal transformations related to sustainability is needed. In the educational debate on sustainability learning, transformative learning theories are widely used. To analyze specific phases of transformative learning, we derived five meta-phases from the literature (novel experience, reflection...
Hibernation enables many species of the mammalian kingdom to overcome periods of harsh environmental conditions. During this physically inactive state metabolic rate and body temperature are drastically downregulated, thereby reducing energy requirements (torpor) also over shorter time periods. Since blood cells reflect the organism´s current condition, it was suggested that transcriptomic alterations in blood cells mirror the...
ATLANTIC EPIPHYTES : a data set of vascular and non‐vascular epiphyte plants and lichens from the Atlantic ForestNARA Subscribed
Epiphytes are hyper‐diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non‐vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence a...
Aim Species attributes are often used to explain diversity patterns across assemblages/communities. However, repeated species co‐occurrences can generate spatial pattern and strong statistical relationships between aggregated attributes and richness in the absence of biological information. Our aim is to increase awareness of this problem. Location North America. Methods We generated empirical species richness patterns using t...
Viability of cyclic populationsNARA Subscribed
Theory on viability of small populations is well developed and has led to the standard methodology of population viability analysis ( PVA ) to assess vulnerability of single species. However, more complex situations involving community dynamics or environmental change violate theoretical assumptions. Synthesizing concepts from population, community, and conservation ecology, we develop a generic theory on the viability of cycl...
Host‐associated genomic differentiation in congeneric butterflies: now you see it, now you do notNARA Subscribed
Ecotypic variation among populations may become associated with widespread genomic differentiation, but theory predicts that this should happen only under particular conditions of gene flow, selection and population size. In closely related species, we might expect the strength of host‐associated genomic differentiation ( HAD ) to be correlated with the degree of phenotypic differentiation in host‐adaptive traits. Using micros...
Process, correlation and parameter fitting in species distribution models: a response to Kriticos et alNARA Subscribed
In a recent article (Dormann et al ., 2012, Journal of Biogeography , 39, 2119–2131), we compared different approaches to species distribution modelling and depicted modelling approaches along an axis from purely ‘correlative’ to ‘forward process‐based’ models. In their correspondence, Kriticos et al . (2013, Journal of Biogeography , doi: 10.1111/j.1365‐2699.2012.02791.x ) challenge this view, claiming that our continuum repr...
Within the field of species distribution modelling an apparent dichotomy exists between process‐based and correlative approaches, where the processes are explicit in the former and implicit in the latter. However, these intuitive distinctions can become blurred when comparing species distribution modelling approaches in more detail. In this review article, we contrast the extremes of the correlative–process spectrum of species...
The ability of species to modulate environmental conditions and resources has long been of interest. In the past three decades the impacts of these biotic modifiers have been investigated as ‘ecosystem engineers’, ‘niche constructors’, ‘facilitators’ and ‘keystone species’. This environmental modulation can vary spatially from extremely local to global, temporally from days to geological time, and taxonomically from a few to a...
How to understand species’ niches and range dynamics: a demographic research agenda for biogeographyNARA Subscribed
Range dynamics causes mismatches between a species’ geographical distribution and the set of suitable environments in which population growth is positive (the Hutchinsonian niche). This is because source–sink population dynamics cause species to occupy unsuitable environments, and because environmental change creates non‐equilibrium situations in which species may be absent from suitable environments (due to migration limitati...
Towards novel approaches to modelling biotic interactions in multispecies assemblages at large spatial extentsNARA Subscribed
Aim Biotic interactions – within guilds or across trophic levels – have widely been ignored in species distribution models (SDMs). This synthesis outlines the development of ‘species interaction distribution models’ (SIDMs), which aim to incorporate multispecies interactions at large spatial extents using interaction matrices. Location Local to global. Methods We review recent approaches for extending classical SDMs to incorpo...
