Kopsco, H. L., P. Gronemeyer, N. Mateus-Pinilla, and R. L. Smith. 2023. Current and Future Habitat Suitability Models for Four Ticks of Medical Concern in Illinois, USA. Insects 14: 213.

The greater U.S. Midwest is on the leading edge of tick and tick-borne disease (TBD) expansion, with tick and TBD encroachment into Illinois occurring from both the northern and the southern regions. To assess the historical and future habitat suitability of four ticks of medical concern within the state, we fit individual and mean-weighted ensemble species distribution models for Ixodes scapularis, Amblyomma americanum, Dermacentor variabilis, and a newly invading species, Amblyomma maculatum using a variety of landscape and mean climate variables for the periods of 1970–2000, 2041–2060, and 2061–2080. Ensemble model projections for the historical climate were consistent with known distributions of each species but predicted the habitat suitability of A. maculatum to be much greater throughout Illinois than what known distributions demonstrate. The presence of forests and wetlands were the most important landcover classes predicting the occurrence of all tick species. As the climate warmed, the expected distribution of all species became strongly responsive to precipitation and temperature variables, particularly precipitation of the warmest quarter and mean diurnal range, as well as proximity to forest cover and water sources. The suitable habitat for I. scapularis, A. americanum, and A. maculatum was predicted to significantly narrow in the 2050 climate scenario and then increase more broadly statewide in the 2070 scenario but at reduced likelihoods. Predicting where ticks may invade and concentrate as the climate changes will be important to anticipate, prevent, and treat TBD in Illinois.

Motivation Aquatic insects comprise 64% of freshwater animal diversity and are widely used as bioindicators to assess water quality impairment and freshwater ecosystem health, as well as to test ecological hypotheses. Despite their importance, a comprehensive, global database of aquatic insect occurrences for mapping freshwater biodiversity in macroecological studies and applied freshwater research is missing. We aim to fill this gap and present the Global EPTO Database, which includes worldwide geo-referenced aquatic insect occurrence records for four major taxa groups: Ephemeroptera, Plecoptera, Trichoptera and Odonata (EPTO). Main type of variables contained A total of 8,368,467 occurrence records globally, of which 8,319,689 (99%) are publicly available. The records are attributed to the corresponding drainage basin and sub-catchment based on the Hydrography90m dataset and are accompanied by the elevation value, the freshwater ecoregion and the protection status of their location. Spatial location and grain The database covers the global extent, with 86% of the observation records having coordinates with at least four decimal digits (11.1 m precision at the equator) in the World Geodetic System 1984 (WGS84) coordinate reference system. Time period and grain Sampling years span from 1951 to 2021. Ninety-nine percent of the records have information on the year of the observation, 95% on the year and month, while 94% have a complete date. In the case of seven sub-datasets, exact dates can be retrieved upon communication with the data contributors. Major taxa and level of measurement Ephemeroptera, Plecoptera, Trichoptera and Odonata, standardized at the genus taxonomic level. We provide species names for 7,727,980 (93%) records without further taxonomic verification. Software format The entire tab-separated value (.csv) database can be downloaded and visualized at Fifty individual datasets are also available at, while six datasets have restricted access. For the latter, we share metadata and the contact details of the authors.

LIZARDO, V., V. MOCTEZUMA, and F. ESCOBAR. 2022. Distribution, Regionalization, and Diversity of the dung beetle genus Phanaeus MacLeay (Coleoptera: Scarabaeidae) using Species Distribution Models. Zootaxa 5213: 546–568.

The genus Phanaeus is a well-known group whose taxonomy has been described multiple times. Its distribution was previously classified into 11 ecogeographic groups that are equivalent to areas of endemism. Here we use Species Distribution Models to describe species richness patterns. We measured beta-diversity and regionalized its distribution into one region and one transition zone, both with three dominions: Mexican Transition Zone (North American, Mexican, and Mesoamerican dominions) and Neotropical region (Pacific, Brazilian, and Atlantic Forest dominions). We also present a species checklist and updated the distribution maps for 73 of 81 species described so far that reflects all the taxonomical updates. We include a list of all the recorded locations (by country, state, and province), list the recorded habitats and biomes, and describe the modelled environmental conditions for each species.

Our understanding of broad-scale biodiversity and functional trait patterns is largely based on plants, and relatively little information is available on soil arthropods. Here, we investigated the distribution of termite diversity globally and morphological traits and diversity across China. Our analyses showed increasing termite species richness with decreasing latitude at both the globally, and within-China. Additionally, we detected obvious latitudinal trends in the mean community value of termite morphological traits on average, with body size and leg length decreasing with increasing latitude. Furthermore, temperature, NDVI and water variables were the most important drivers controlling the variation in termite richness, and temperature and soil properties were key drivers of the geographic distribution of termite morphological traits. Our global termite richness map is one of the first high resolution maps for any arthropod group and especially given the functional importance of termites, our work provides a useful baseline for further ecological analysis.

Montañez-Reyna, M., J. L. León-Cortés, F. Infante, E. J. Naranjo, and A. Gómez-Velasco. 2022. Diversity and Climatic Distribution of Moths in the Tribe Arctiini (Lepidoptera: Erebidae: Arctiinae) in Mexico P. Shi [ed.],. Annals of the Entomological Society of America 115: 253–266.

Abstract The Mexican lepidopteran fauna is particularly diverse, but many moth groups remain poorly documented. The tribe Arctiini is a species-rich group that has been used as a reliable indicator of environmental change. However, little is known about the fauna of the tribe Arctiini in Mexico, and there is no exhaustive review of its diversity and distribution patterns. Our aims were: 1) to account for the species diversity and distribution patterns of the tribe Arctiini; 2) to build spatial distributions and discuss possible changes in the distribution areas of the tribe Arctiini using conservative (RCP 2.6) and liberal (RCP 8.5) future climate scenarios; and 3) to discuss the conservation implications for key taxa that due to their life history characteristics and restricted distribution, might require particular conservation actions. We compiled a total of 16,385 records and 548 species in seven subtribes. Diversity profiles revealed higher cumulative species richness and diversity for the subtribes Phaegopterina, Ctenuchina, and Euchromiina, and we identified a pattern of decreasing species diversity with elevation. In addition, we estimated that 35% and 84% of modeled species in future conservative and liberal climatic scenarios, respectively, would result in significant losses of climatic suitability and shifts in spatial distribution. The endemic species, Virbia semirosea, Poliopastea jalapensis, and Pygoctenucha azteca would likely reduce their distribution by approximately 50% in both climatic scenarios. Maintaining a network of highly threatened habitats (e.g., cloud forests, tropical rain forests) will be essential to preserve persisting species populations and to increase likely (re)colonization events.

Marshall, B. M., C. T. Strine, C. S. Fukushima, P. Cardoso, M. C. Orr, and A. C. Hughes. 2022. Searching the web builds fuller picture of arachnid trade. Communications Biology 5.

Wildlife trade is a major driver of biodiversity loss, yet whilst the impacts of trade in some species are relatively well-known, some taxa, such as many invertebrates are often overlooked. Here we explore global patterns of trade in the arachnids, and detected 1,264 species from 66 families and 371 genera in trade. Trade in these groups exceeds millions of individuals, with 67% coming directly from the wild, and up to 99% of individuals in some genera. For popular taxa, such as tarantulas up to 50% are in trade, including 25% of species described since 2000. CITES only covers 30 (2%) of the species potentially traded. We mapped the percentage and number of species native to each country in trade. To enable sustainable trade, better data on species distributions and better conservation status assessments are needed. The disparity between trade data sources highlights the need to expand monitoring if impacts on wild populations are to be accurately gauged and the impacts of trade minimised. Trade in arachnids includes millions of individuals and over 1264 species, with over 70% of individuals coming from the wild.

1. Historical museum records provide potentially useful data for identifying drivers of change in species occupancy. However, because museum records are typically obtained via many collection methods, methodological developments are needed in order to enable robust inferences. Occupancy‐detection models, a relatively new and powerful suite of statistical methods, are a potentially promising avenue because they can account for changes in collection effort through space and time.
