Raccoons ( Procyon lotor ) are the primary terrestrial wildlife reservoir for Lyssavirus rabies within the United States. The raccoon rabies variant (RRVV) is actively managed at landscape scales using oral rabies vaccination (ORV) within the eastern United States. To effectively manage RRVV, it is important to know the density of raccoons to appropriately scale the density of ORV baits distributed on the landscape. We compared methods to estimate raccoon densities from camera‐trap data versus more intensive capture‐mark‐recapture (CMR) estimates across 2 land cover types (upland pine and bottomland hardwood) in the southeastern United States during 2019 and 2020. We evaluated the effect of alternative camera configurations and durations of camera trapping on density estimates and used an N‐mixture model to estimate raccoon densities, including covariates on abundance and detection. We further compared different methods of scaling camera‐based counts, with the maximum number of raccoons seen on any given image within a day best explaining density. Camera‐trap density estimates were moderately correlated with CMR estimates ( r = 0.56). However, densities from camera‐trap data were more reliable when classifying category of density as an index used to inform management (83% correct when compared to CMR estimates), although the densities in our study fell into the 2 lowest density classes only. Using more cameras reduced bias and uncertainty around density estimates; however, if ≤ 6 camera traps were used at a site, a line transect approach proved less biased than a grid design. Camera trapping should be conducted for at least 3 weeks for more accurate estimates of raccoon population density in our study area (< 5% bias). We show that camera‐trap data can be used to assign raccoon densities to management‐relevant density index bins, but more studies are needed to ensure reliability across a greater range of environmental conditions and raccoon densities.

Buck Jolley , United States Department of Agriculture, Animal and Plant Health Inspection Service, Wildlife Services, Guam State Office Citation Proceedings, 31st Vertebrate Pest Conference, paper 10 Published August 30, 2024 Editors: Robert M. Timm and D. M. Woods Abstract Interspecific interactions are crucial in shaping ecosystem dynamics (Connell 1983, Tilman 1987, Barbosa and Castellanos 2005). Non-native ungulates have been introduced across the globe (Ferretti and Lovari 2014, Volery et al. 2021) and in environments where multiple invasives thrive, these co-occurring sympatric species may shift spatiotemporal patterns to minimize interspecific competition (Schoener 1974, Chesson 2000). Spatiotemporal shifts can lead to cascading effects to the native flora and fauna (Simberloff and Von Holle 1999). Given the potential negative impacts, understanding these interactions is vital for effective management of these ecosystems. Two invasive ungulates, the wild pig ( Sus scrofa ) and the Philippine deer ( Rusa marianna ), have inhabited much of Guam since their introduction in the 1600s and 1700s (Intoh 1986, Wiles et al. 1999) and both have been associated with significant ecological damage throughout the island (Conroy 1989). Despite sharing similar invasive roles, they seemingly coexist throughout areas of Guam. Subsequently, efforts are increasingly put forth to remove both species from partitioned areas at one time. To aid these efforts and understand invasive species interactions, we studied the seasonal spatiotemporal patterns of wild pigs and Philippine deer during February 2021-March 2022. Specifically, we used GPS collars from 39 wild pigs and 22 deer to examine spatial and temporal partitioning and assess dynamic spatiotemporal interactions between interspecific dyads at seasonal scales. We investigated spatial partitioning of wild pigs and deer by estimating the spatial overlap between home ranges and core areas of interspecific neighboring dyads. We estimated temporal overlap in diel activity to evaluate temporal partitioning between the species. Lastly, we examined dynamic spatiotemporal interactions, those that occur simultaneously in space and time, by estimating movement interactions between neighboring interspecific dyads to understand attraction and avoidance. We found spatial overlap between the species decreased significantly in core areas compared to home ranges in both seasons. Within home ranges, deer were approximately 3 times more likely to be within pig ranges than vice versa. This effect diminished at core areas such that deer were only 1.3× more likely to be within pig core ranges than vice versa. Temporal overlap of activity between wild pigs and deer was very high during dry and wet seasons, with overlapping activity peaks during crepuscular hours. At a critical distance threshold of 50m, we estimated 77 movement interactions from 58 dyad pairs over 3 seasons and found that only 2 (2.6%) and 4 (5.2%) movement interactions were considered avoidant and attractive, respectively, and the remaining 71 interactions (92.2%) were neutral. Our results showed that, while not extensive, spatial overlap between wild pigs and deer occurred between home ranges. More exclusive use of core areas suggests that spatial partitioning of these smaller space use areas might serve as one mechanism facilitating coexistence between wild pigs and Philippine deer. Additionally, we did not see any evidence of temporal partitioning or avoidance between wild pigs and deer. Using this knowledge, managers can maximize efficiency of managing invasive ungulates by combining efforts during crepuscular hours when both species are most active. Management activities to remove these species simultaneously may be most effective in areas of known spatial overlap (i.e., home range overlap) and, if that is unknown, managers should default to removal efforts within deer ranges as the odds of encountering both species is higher than in pig’s home ranges.

The animal appeared to be wearing a delicate pearl necklace. Unsure of what they were seeing, the team turned to a colleague who specializes in mites for answers. Ricardo Bassini-Silva, a researcher and curator of the laboratory's Acarological Collection, quickly recognized that the bead-like structures were actually mite larvae. Until now, Brazil had only one documented case of mites that parasitize spiders, and that species belonged to a completely different family. A New Parasitic Mite Identified Detailed analysis of the spider and its tiny passengers followed. Using light microscopy, scanning techniques, and other morphological examinations, the researchers confirmed they were looking at a new species. The finding represents the second spider-parasitic mite ever described in Brazil and the first from its family recorded in the country. The research was supported by FAPESP and published in the International Journal of Acarology. It brought together two FAPESP-funded projects. One is led by Bassini-Silva, while the other is coordinated by Fernando de Castro Jacinavicius, a co-author of the study and a professor at the Institute of Biology at the University of São Paulo (IB-USP). Expanding the Map of a Rare Genus The newly identified species, named Araneothrombium brasiliensis, belongs to a genus first described in Costa Rica in 2017. Finding it in Brazil suggests the group may be more widespread than previously thought and could exist in other neotropical regions. Each mite larva measures about 500 micrometers, or half a millimeter. The spiders they parasitize are only a few millimeters long. So far, scientists have identified only the larval stage of the mite. These larvae were found attached to juvenile spiders from three different families. All collected specimens were engorged, showing they had fed enough to significantly increase their size. "For this group of mites, it isn't uncommon to know many parasitic species only through their larvae, since in adulthood they become free-living predators, living in the soil and feeding on small insects and even other mites, which makes them very difficult to find," says Bassini-Silva. Where the Parasitized Spiders Were Found The spiders carrying the newly described mites were collected in Pinheiral, a municipality in the state of Rio de Janeiro. The area is located near caves and grottos, an environment similar to where Brazil's first known spider-parasitic mite species, Charletonia rocciai, was discovered. In a separate study published in 2022, researchers revisited that earlier species, which was originally described in 1979. The updated work added new details about its physical traits, biology, geographic distribution, and host organisms, including spiders. Why the Mites Target a Spider's Weak Spot Spider-parasitic mites feed on lymph, a fluid that circulates through the bodies of certain arthropods. They draw out this fluid through the pedicel, the narrow region connecting the cephalothorax (where the spider's eyes and mouth are located) to the abdomen. "This is the spider's most vulnerable region since other parts have a lot of chitin, which forms an exoskeleton difficult for the mites' fangs to penetrate," the researcher explains. The mites' tendency to latch onto juvenile spiders suggests opportunistic behavior, since younger spiders are more exposed to parasites and predators. Researchers also note that the species may not be limited to spiders. It could potentially parasitize other arthropods, including insects. This broader behavior has already been observed in Charletonia rocciai, which feeds on at least two different insect orders. Hidden Biodiversity in Museum Collections "With more than 3,000 species of spiders alone, Brazil has immense potential for discovering new parasitic mites," says Bassini-Silva. The discovery also underscores the value of zoological collections for biodiversity research. The spiders examined in this study had been stored for years, and the mites went unnoticed until now. According to Bassini-Silva, collaborations with field researchers and environmental consulting companies may soon lead to more samples. He hopes these efforts will result in the identification and description of additional mite species associated with a wide range of animals.
