Criollo and Crossbred Steer Comparison: Weight Gain, Grazing, Carcass Quality, 2015-2017
Rarámuri Criollo cows have behavioral traits that are desirable for rangelands in arid environments, but calves from this biotype are difficult to market through conventional methods. One strategy to improve marketability is to crossbreed these cows with traditional beef breed bulls. However, it is unclear whether crossbred calves will achieve marketable weights and carcass qualities on rangeland and whether they will retain the desirable grazing behaviors of their mothers. We evaluated these traits for two cohorts of Rarámuri Criollo (JRC), Mexican Criollo (MC), and Criollo × beef-breed crossbred (XC) steers. Final live and carcass weights of XC were greater than JRC and MC, but all three groups were market ready at 30-mo after finishing on grass. Carcass quality and average daily gain did not differ among biotypes. Both JRC and XC steers exhibited grazing patterns similar to those previously observed in JRC cows. These results suggest JRC, MC, and XC steers can achieve desirable slaughter weights in 30 months using a rangeland-based grass-fed protocol, and JRC and XC steers retain desirable grazing behaviors of JRC cows.

Entomological identification of the cadaver fauna of wolf and lynx carcasses in Germany between 2014-2021
The frequency of illegal killings of animals that are under special protection in Germany is continuously increasing. Especially the carnivores wolf and lynx are strongly threatened by humans. To counteract these developments, it is necessary to investigate and prosecute such offenses. An important clue for police investigations is the time of death of the deceased animal. Forensic entomology makes use of the knowledge of temperature-dependent development rates as well as succession patterns of necrophagous flies and beetles and to determine an approximate time of death. While the carcass fauna of other species as well as humans is well studied, the composition of insects on wolves and lynx worldwide has not yet been deciphered. The aim of this work is to investigate the carcass fauna of wolf and lynx. For this purpose, the species composition of insects from 70 wolf carcasses and 8 lynx carcasses was analysed with respect to different habitat types, decomposition stages, and seasons. This data set provides extensive knowledge of the arthropod fauna on wolf and lynx carcasses.

Data from: 'A large, infrequent ecosystem subsidy (cicada carcasses) and warming additively accelerate development and increase growth of larval amphibians'
These data are from an experiment designed to quantify how ecosystem subsidies and elevated temperatures affect pond food webs, focusing on the response of frogs and the mechanisms affecting their responses. The subsidy we examined was the deposition of periodical cicada carcasses into ponds, simulating a large subsidy event that happens only every 17 years. The 7-week experiment was conducted in outdoor tanks using a factorial design with four treatments: Control (no subsidy, ambient temperature); Cicadas (cicada carcasses added in one large pulse); Warming (temperature elevated about 2.6°C above ambient); and Cicadas & Warming. The data set includes two frog response variables: time to metamorphosis (days) and size at metamorphosis (g wet mass). It also includes temperature in each tank, measured at 30-minute intervals. In addition, it includes data designed to characterize resource supply to frogs, including the abundance of periphyton and phytoplankton measured as chlorophyll concentration; periphyton and phytoplankton composition at the Division level using data from a spectrofluoroprobe; and water column nutrient concentrations, including ammonium, nitrate, total nitrogen, soluble reactive phosphorus, and total phosphorus. In addition, we estimated algal gross primary production using data on dissolved oxygen measured at 30-minute intervals, and include oxygen data here. Finally, we measured the rate at which cicada carcasses and leaf litter decomposed, and dissolved organic carbon concentrations at the end of the experiment, as these data may shed light on factors affecting nutrient supply to algae as well as ecosystem respiration rates, which are used to estimate gross primary production rates. Thus, we include data on the mass of cicada carcasses and leaf litter on several dates, as well as DOC concentrations on the last day of the experiment.

Data from: Coyotes display minimal response to Cougar scent at experimental carcass sites
<p>Interactions among predators can have cascading impacts on communities and ecosystems. These interactions often occur around carrion, where the carrion provides a food reward, but also a risk of encountering other, potentially dominant, predators. Understanding how predators balance risk and reward at carrion, and how perceived risk changes in response to carcass origins and conditions, provides valuable insight into intraguild interactions. We investigated Coyote (Canis latrans) behavior at carrion simulated as cache sites treated with Cougar (Puma concolor) scent versus carrion used as control sites to better understand how Coyotes assess risk while feeding on carrion. Coyotes displayed similar behavior between sites treated and untreated with Cougar scent, suggesting that the presence of Cougar scent did not alter perceived risk by coyotes in our study. Instead, coyote behavior responded to carcass age, elevation, and whether avian scavengers had visited the carcass. Coyotes spent more time feeding, more time on camera, and touched carcasses quicker as carcass age increased. Avian scavengers appeared to compete with Coyotes, and while the presence of avian scavengers reduced time to carcass detection by Coyotes, it also decreased time spent feeding. These results suggest that carcass condition is a more important indicator of risk and reward than the presence of dominant predator scent to Coyotes. Predator scent may be an unreliable cue of immediate predator presence. Alternatively, all carcasses may be risky because dominant predators also scavenge carrion, creating similar risk regardless of previous visitation by dominant predators. These results provide insights into predator interactions and can also inform the use of scent cues in wildlife management.</p>
