“…These gradients are large-scale, recur in the landscape and impose similar constraints upon all the species in them, leading to well-known convergences in traits such as succulence in arid environments or long-lived leaves in resource-poor habitats (Reich et al 1999). These b niche traits are likely to be subject to phylogenetic niche conservatism (Harvey & Pagel 1991) which will constrain their evolution (though there may be exceptions such as in scrub jays; see Rice et al 2003).…”

A significant proportion of the global diversity of flowering plants has evolved in recent geological time, probably through adaptive radiation into new niches. However, rapid evolution is at odds with recent research which has suggested that plant ecological traits, including the b-(or habitat) niche, evolve only slowly. We have quantified traits that determine within-habitat a diversity (a niches) in two communities in which species segregate on hydrological gradients. Molecular phylogenetic analysis of these data shows practically no evidence of a correlation between the ecological and evolutionary distances separating species, indicating that hydrological a niches are evolutionarily labile. We propose that contrasting patterns of evolutionary conservatism for a-and b-niches is a general phenomenon necessitated by the hierarchical filtering of species during community assembly. This determines that species must have similar b niches in order to occupy the same habitat, but different a niches in order to coexist.

“…Ancestral-state reconstruction methods for continuous traits assume that each trait evolves according to a stochastic Brownian motion process, with a probability of change along a branch proportional to the length of the branch (21). Although many papers show ancestral-state reconstructions of environmental niche components using this model (15,19,23,24), they fail to provide tests showing whether their data fit this model of evolution, whereas others do not provide an explicit model for niche reconstructions (25,26). The different hypotheses tested with our model for scaling parameters showed a deviation from a Brownian model.…”

Ecological niches evolve through time, but at different rates and to different degrees. An integrated approach using diverse databases, methods, and analytical tools is used to estimate climate envelopes for species of salamanders (family Salamandridae). These species, which range widely across the Holarctic and have a rich and long fossil record, are used to probe the evolutionary dynamics of niches studied in a phylogenetic context through time and across space. Climate data and statistical methods are used to estimate niche dimensions related to precipitation and temperature, in both a phylogenetic and ecogeographic context. Using phylogenetic methods, climate envelopes are estimated for segments of a time-calibrated phylogenetic tree of salamandrids, to explore how far back in time it is reasonable to make such estimates. Our research strategy illuminates some of the challenges and limitations of the available data and methods and identifies potential solutions, such as the need for physiological and behavioral data that may help to better define species' niches or the development of novel evolutionary models that account for paleoclimatic data. We explore and analyze limits to the application of currently available methodologies. Organisms known to have evolved slowly and conservatively, and which are ectotherms and likely to be profoundly affected by climatic variables, may be the most useful for studies of this kind.Grinnellian niches ͉ niche evolution ͉ phylogenetic analysis ͉ Salamandridae

“…This comparison allowed us to identify possible spatial (in geographical space) relationships among species. However if these spatial relationships exist, only experimental approaches can test the existence of a causal link (Connell 1983;Schoener 1983;Anderson et al, 2002;Rice et al, 2003).…”

Cola lorougnonis is an endemic, rare, and treated species. It was recently recorded in Dékpa forest near Agbaou (a village of Divo region, Côte d'Ivoire). In the same forest, 20 other rare and endemic plant species were recorded. Accurate modeling of geographical distributions of these species is crucial to various applications in ecology and biodiversity conservation. The present study analyzed suitable habitat models for the 21 species. The main objective was to test geographical predictions for the focused species: Cola lorougnonis. We used Maxent modelling method for predicting potential suitable habitats combining environmental variables and species records. We evaluated Maxent predictions using the area under the receiver-operating characteristic curve (AUC). For each species, the map of distribution was engineered using DIVA-GIS. We compared the suitable habitat areas among species. Principal Canonical Analysis allowed the ordination of species according to environmental variables. AUC values allowed to get 11 species with excellent distribution models, 8 species with good distribution models, and 2 species with predictive models considered as acceptable. Cola lorougnonis (AUC = 0.99) and Drypetes singroboensis (AUC = 0.96) have the same focused area: moist semi-deciduous forest in Côte d'Ivoire. They are more sensitive to changes in rainfall of both warmest and coldest seasons. The State of Côte d'Ivoire has to undertake monitoring, assessment and reporting of conservation status facilitation for all habitats where these species could be found within the territory. Additional studies focusing on the investigation areas and niche models onto future conditions of climate could be considered.
