The iNaturalist platform generates millions of research-grade biodiversity records via a system in which users collectively reach consensus on taxonomic identification. In the present article, we examine how identifiers and their efforts, an understudied component of the platform, support data generation. Identification is keeping pace with rapid g...

Butterfly migration across great distances is testimony to their impressive aeronautical skills. Wing size and shape are two key determinants of flight performance, and in butterflies, the specific configuration of forewings to hindwings including the overlapping area between them can have profound effects on overall size and shape. Here we use qua...

Butterflies are a diverse and charismatic insect group that are thought to have evolved with plants and dispersed throughout the world in response to key geological events. However, these hypotheses have not been extensively tested because a comprehensive phylogenetic framework and datasets for butterfly larval hosts and global distributions are la...

Here, we present the largest, global dataset of Lepidopteran traits, focusing initially on butterflies (ca. 12,500 species records). These traits are derived from field guides, taxonomic treatments, and other literature resources. We present traits on wing size, phenology,voltinism, diapause/overwintering stage, hostplant associations, and habitat...

Butterflies are a diverse and charismatic insect group that are thought to have diversified via coevolution with plants and in response to dispersals following key geological events. These hypotheses have been poorly tested at the macroevolutionary scale because a comprehensive phylogenetic framework and datasets on global distributions and larval...

Citizen science has been in practice since the 1800s and is an important source of data for scientists and other applied users. It plays a vital role in democratizing science, providing equitable access to scientific participation and data, helps build the capacity of its participants, inculcates the spirit of scientific endeavor and discovery and...

Biodiversity inventory is among the major challenges for conservation biology in the face of global change. Species exist in two spaces that are linked in the so‐called Hutchinsonian Duality: distributions in geographical space and ecological niches in environmental space. We explore implications of using distinct methods to select locations for bi...

Motivation Insects provide vital ecological functions and account for over half of all described species. An at least basic understanding of their geographical distributions is key for addressing a range of central ecological and evolutionary questions and to inform conservation. However, even for popular groups, such as butterflies, the knowledge...

Aim: Comprehensive, global information on species' occurrences is an essential biodiversity variable and central to a range of applications in ecology, evolution, biogeography and conservation. Expert range maps often represent a species' only available distributional information and play an increasing role in conservation assessments and macroeco...

Yucca in the American desert Southwest typically flowers in early spring, but a well-documented anomalous bloom event occurred during an unusually cold and wet late fall and early winter 2018–2019. We used community science photographs to generate flowering presence and absence data. We fit phenoclimatic models to determine which climate variables...

Insect phenological lability is key for determining which species will adapt under environmental change. However, little is known about when adult insect activity terminates and overall activity duration. We used community-science and museum specimen data to investigate the effects of climate and urbanisation on timing of adult insect activity for...

The availability of citizen science data has resulted in growing applications in biodiversity science. One widely used platform, iNaturalist, provides millions of digitally vouchered observations submitted by a global user base. These observation records include a date and a location but otherwise do not contain any information about the sampling p...

Research projects in ecology or biodiversity either start with an area of study or a target species list. Working with these species lists or taxonomic lists is not as straightforward as it seems. The taxonomic names that are considered to be “standard,” are surprisingly dynamic. Over time, the names keep changing with ongoing research and advancem...

The amount of observational and specimen-based biodiversity data available to researchers is increasing exponentially, yet the ability to manage and cite large, complex biodiversity datasets lags behind. This management and citation gap impedes reproducibility for data users and the ability for data publishers to track use and accumulate use citati...

Broad-scale, quantitative assessments of insect biodiversity and the factors shaping it remain particularly poorly explored. Here we undertook a spatial phylogenetic analysis of North American butterflies to test whether climate stability and temperature gradients have shaped their diversity and endemism. We also performed the first quantitative co...

Aggregate biodiversity data from museum specimens and community observations have promise for macroscale ecological analyses. Despite this, many groups are under‐sampled, and sampling is not homogeneous across space. Here we used butterflies, the best documented group of insects, to examine inventory completeness across North America. We separated...

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 of flowering) and duration of populations of the same species vary along environmental gradients. Understanding these patterns is critical for predicting the effects of future climate an...

National Moth Week (NMW) is a global citizen science project initiated in 2012 by Friends of the East Brunswick Environmental Commission, a non-profit organization in New Jersey. The focus of this project is to record populations of moths with involvement of citizens. In 2013 itself DiversityIndia partnered with the NMW team to initiate the program...

Broad-scale quantitative assessments of biodiversity and the factors shaping it remain particularly poorly explored in insects. Here, we undertook a spatial phylogenetic analysis of North American butterflies via assembly of a time-calibrated phylogeny of the region coupled with a unique, complete range assessment for ~75% of the known species. We...

Medicinal plants have become of great relevance to the health care of the people, with a vast global population still relying on them. While developing the nation’s most comprehensive, multidisciplinary database on flora, fauna, metals, and minerals of traditional Materia Medica from primary texts over the period 1500 BC to 1900 AD, IMPLAD (Indian...

Biodiversity studies rely heavily on estimates of species' distributions often obtained through ecological niche modelling. Numerous software packages exist that allow users to model ecological niches using machine learning and statistical methods. However, no existing package with a graphical user interface allows users to perform model calibratio...

Reconstructing ecological niche evolution can provide insight into the biogeography and diversification of evolving lineages. However, comparative phylogenetic methods may infer the history of ecological niche evolution inaccurately because (a) species' niches are often poorly characterized; and (b) phylogenetic comparative methods rely on niche su...

Pachliopta aristolochiae has been assessed as Least Concern. In 1985, Collins and Morris listed this species as 'generally common and not threatened'. It appears that this species is still very common and widespread, with an estimated extent of occurrence of around 20 million km2. Although some localized threats may be present, in general, this spe...

Premise: Citizen science platforms for sharing photographed digital vouchers, such as iNaturalist, are a promising source of phenology data, but methods and best practices for use have not been developed. Here we introduce methods using Yucca flowering phenology as a case study, because drivers of Yucca phenology are not well understood despite th...

Broad-scale plant flowering phenology data has predominantly come from geographically and taxonomically restricted monitoring networks. However, platforms such as iNaturalist, where citizen scientists upload photographs and curate identifications, provide a promising new source of data. Here we develop a general set of best practices for scoring iN...

There is an urgent need to start protecting remaining biodiversity for the survival of humanity. Anthropogenic pressures and global climate change are pushing several species towards extinction. To protect any species it is essential to have detailed information of the geographical distributions and population trends. Here we describe how key areas...

Insects are possibly the most taxonomically and ecologically diverse class of multicellular organisms on Earth. Consequently, they provide nearly unlimited opportunities to develop and test ecological and evolutionary hypotheses. Currently, however, large-scale studies of insect ecology, behavior, and trait evolution are impeded by the difficulty i...

A new R package for biodiversity data cleaning, 'bdclean', was initiated in the Google Summer of Code (GSoC) 2017 and is available on github. Several R packages have great data validation and cleaning functions, but 'bdclean' provides features to manage a complete pipeline for biodiversity data cleaning; from data quality explorations, to cleaning...

Species invasions represent a significant dimension of global change yet the dynamics of invasions remain poorly understood and are considered rather unpredictable. We explored interannual dynamics of the invasion process in the Eurasian collared dove (Streptopelia decaocto) and tested whether the advance of the invasion front of the species in Nor...

Increasing number of scientists are using R for their data analyses, however, proficiency required to manage biodiversity data in R is considerably rarer. Since, users need to retrieve, manage and assess high-volume data with inherent complex structure (Darwin Core standard, DwC), various R packages dealing with biodiversity data and specifically d...

Summary: Biodiversity studies are relying increasingly on primary biodiversity records (PBRs) for modelling and analysis. Because biodiversity data are frequently ‘harvested’ — i.e., not collected by the researcher for that particular study, but obtained from data aggregators such as the Global Biodiversity Information Facility — researchers need t...

Traditionally, biological resources have been used extensively for health care, healing practices and livelihoods. Ethno-biographical accounts narrate their widespread and informed use among various populations and cultures. Knowledge related to their use is specific. Local communities play a crucial role for linking knowledge on characterization o...

ABSTRACT: Abundance and other aspects of population ecology have long been known to contribute to shaping the geography of speciesí distributions. In particular, abundance patterns have recently been shown to negatively correlate with environmental distance from conditions in the center of a speciesí abiotic niche, rather than vary with distance fr...

The Audubon Core Multimedia Resource Metadata Schema (simply “Audubon Core” or “AC”) is a representation-free vocabulary for the description of biodiversity multimedia resources and collections, now in the final stages as a proposed standard under TDWG Biodiversity Information Standards.
