Background Ecological niche modeling is a set of analytical tools with applications in diverse disciplines, yet creating these models rigorously now challenging task. The calibration phase critical, but despite recent attempts at providing for performing this step, adequate detail still missing. Here, we present the kuenm R package, new detailed development ecological using platform Maxent reproducible way. Results This package takes advantage versatility and to enable model selection, final...
Abstract Biodiversity studies rely heavily on estimates of species' distributions often obtained through ecological niche modelling. Numerous software packages exist that allow users to model niches using machine learning and statistical methods. However, no existing package with a graphical user interface allows perform calibration selection based convex forms such as ellipsoids, which may match fundamental shapes better, incorporating tools for exploring, modelling, evaluating are...
Abstract Aim Ecological niche modelling ( ENM ) and species distribution SDM have been used extensively to study biogeographic macroecological patterns of terrestrial fauna flora. Few studies date applied marine ecosystems, those that treated the environment as a two‐dimensional space owing limitations implementations current / tools. For many organisms, should be performed in three‐dimensional space, taking into account latitude, longitude depth. We present case demonstrating strategy for ....
Citizen science platforms for sharing photographed digital vouchers, such as iNaturalist, are a promising source of phenology data, but methods and best practices use have not been developed. Here we introduce using
Abstract North America is a large continent with extensive climatic, geological, soil, and biological diversity. As biota faces threat from habitat destruction climate change, making quantitative assessment of biodiversity becomes critically important. Rapid digitization plant specimen records accumulation DNA sequence data enable much‐needed broad synthesis species occurrences phylogenetic data. In this study, the first such flora diverse part world attempted, all seed plants American (here...
Abstract A wave of green leaves and multi‐colored flowers advances from low to high latitudes each spring. However, little is known about how flowering offset (i.e., ending flowering) duration populations the same species vary along environmental gradients. Understanding these patterns critical for predicting effects future climate land‐use change on plants, pollinators, herbivores. Here, we investigated potential climatic landscape drivers onset, offset, 52 plant with varying key traits. We...
Abstract Biodiversity inventory is among the major challenges for conservation biology in face of global change. Species exist two spaces that are linked so‐called Hutchinsonian Duality: distributions geographical space and ecological niches environmental space. We explore implications using distinct methods to select locations biodiversity inventories, based on this idea two‐space distributions. combined empirical statistical facilitate selecting localities either or both considerations....
Abstract Land use and land cover (LULC) change has been identified as an important driver of emerging mosquito‐borne zoonotic diseases. However, studies are often limited to individual vector species, despite the potential for interspecific variation in competency within mosquito assemblages. This can affect transmission hazard, particularly complex multi‐vector disease systems. Here, we used a joint species distribution modeling approach that included West Nile virus (WNV) trait understand...
Recent availability of biodiversity data resources has enabled an unprecedented ability to estimate phylogenetically based metrics over broad scales. Such approaches elucidate ecological and evolutionary processes yielding a biota help guide conservation efforts. However, the choice appropriate phylogenetic underlying input uncertainties may affect interpretation. Here, we address how differences among source trees levels uncertainty these test existing hypotheses regarding geographic...
Evolutionary dynamics of abiotic ecological niches across phylogenetic history can shed light on large-scale biogeographic patterns, macroevolutionary rate shifts, and the relative ability lineages to respond global change. An unresolved question is how best represent reconstruct evolution these complex traits at coarse spatial scales through time. Studies have approached this by integrating comparative methods with niche estimates inferred from correlative other models. However, for...
Broad-scale, quantitative assessments of insect biodiversity and the factors shaping it remain particularly poorly explored. Here we undertook a spatial phylogenetic analysis North American butterflies to test whether climate stability temperature gradients have shaped their diversity endemism. We also performed first comparisons patterns between flowering plants. expected concordance two groups based on shared historical environmental drivers presumed strong butterfly-host plant...
ABSTRACT Aim Geographic distributions of species are constrained by several factors acting at different scales, with climate assumed to be a major determinant broad extents. Recent studies, however, have challenged this statement and indicated that may not dominate among the governing geographic species. Here, we argue these results misleading due lack consideration area has been accessible Location North America. Methods We generated null for 75 American endemic 19 non‐endemic bird For each...
Ecological niche models (ENM) have become a popular tool to define and predict the "ecological niche" of species. An implicit assumption ENMs is that predicted ecological species actually reflects adaptive landscape Thus in sites be highly suitable, would maximum fitness compared poorly suitable. As yet there are very few attempts address this assumption. Here we evaluate We used Bioclim (DIVA GIS version 7.3) Maxent (version 3.3.2) habitat suitability Myristica malabarica Lam., an...

Abstract Insect phenological lability is key for determining which species will adapt under environmental change. However, little known about when adult insect activity terminates and overall duration. We used community‐science museum specimen data to investigate the effects of climate urbanisation on timing 101 varying in life history traits. found detritivores with aquatic larval stages extend periods most rapidly response increasing regional temperature.
