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.

Directed endozoochorous dispersal by scavengers facilitate sexual reproduction in otherwise clonal plants at cadaver sites
<ol> <li>The regeneration niche of many plant species involves spatially and temporally unpredictable disturbances, called recruitment windows of opportunity. However, even species with clear dispersal adaptations such as fleshy berries may not successfully reach such elusive regeneration microsites. Ericaceous, berry-producing species in the northern hemisphere demonstrate this dispersal limitation. They are said to display a reproductive paradox owing to their lack of regeneration in apparently suitable microsites despite considerable investment in producing large quantities of berries.</li> <li>Cadavers generate vegetation-denuded and nutrient-rich disturbances termed cadaver decomposition islands. Cadavers attract facultative scavengers with considerable capacity for endozoochorous seed dispersal. We hypothesize that cadaver decomposition islands facilitate recruitment in berry-producing ericaceous species due to endozoochorous dispersal directed towards favorable microsites with low competition.</li> <li>We examined seedling establishment within a permanent, semi-regular 10 × 10 m grid across an ungulate mass die-off on the Hardangervidda plateau in southeastern Norway. Competing models regarding the relative importance of factors governing recruitment were evaluated, specifically cadaver location (elevated seed rain) and microsite conditions (competition).</li> <li>We found that cadaver decomposition islands did facilitate seedling establishment, as cadaver density was the best predictor of seedling distribution. Other important factors governing seedling establishment such as percentage cover of soil and vascular plants alone were inadequate to explain seedling establishment.</li> <li> <i>Synthesis:</i> This study provides a novel understanding of sexual reproduction in species with cryptic generative reproduction. The directed nature of endozoochorous dispersal combined with long-distance dispersal abilities of medium to large vertebrate scavengers towards cadavers allows plants to exploit the advantageous but ephemeral resource provided by cadaver decomposition islands.</li> </ol>

Cardiac patch transplantation instruments for robotic minimally invasive cardiac surgery: initial proof-of-concept designs and surgery in a porcine cadaver
<p>BACKGROUND: Damaged cardiac tissues could potentially be regenerated by transplanting bioengineered cardiac patches to the heart surface. To be fully paradigm-shifting, such patches may need to be transplanted using minimally invasive robotic cardiac surgery (not only traditional open surgery). Here, we present novel robotic designs, initial prototyping and a new surgical operation for instruments to transplant patches <em>via </em>robotic minimally invasive heart surgery. METHODS: Robotic surgical instruments and automated control systems were designed, tested with simulation software and prototyped. Surgical proof-of-concept testing was performed on a pig cadaver. RESULTS: Three robotic instrument designs were developed. The first (called “Claw” for the claw-like patch holder at the tip) operates on a rack and pinion mechanism. The second design (“Shell-Beak”) uses adjustable folding plates and rods with a bevel gear mechanism. The third (“HeartStamp”) utilizes a stamp platform protruding through an adjustable ring. For the HeartStamp, rods run through a cylindrical structure designed to fit a uniportal Video-Assisted Thorascopic Surgery (VATS) surgical port. Designed to work with or without a sterile sheath, the patch is pushed out by the stamp platform as it protrudes. Two instrument robotic control systems were designed, simulated <em>in silico</em> and one of these underwent early ‘sizing and learning’ prototyping as a proof-of-concept. To reflect real surgical conditions, surgery was run “live” and reported exactly (as-it-happened). We successfully picked up, transferred and released a patch onto the heart using the HeartStamp in a pig cadaver model. CONCLUSION: These world-first designs, early prototypes and a novel surgical operation pave the way for robotic instruments for automated keyhole patch transplantation to the heart. Our novel approach is presented for others to build upon free from restrictions or cost – potentially a significant moment in myocardial regeneration surgery which may open a therapeutic avenue for patients unfit for traditional open surgery.</p>
Natural history and ecological effects on the establishment and fate of Florida carpenter ant cadavers infected by the parasitic-manipulator Ophiocordyceps camponoti-floridani
<p class="MsoNormal">1. <em>Ophiocordyceps</em> fungi manipulate the behavior of their ant hosts to produce a summit disease phenotype, thereby establishing infected ant cadavers onto vegetation at elevated positions suitable for fungal growth and transmission. Multiple environmental and ecological factors have been proposed to shape the timing, positioning, and outcome of these manipulations.</p> <p class="MsoNormal">2. We conducted a long-term field study of <em>Ophiocordyceps</em> <em>camponoti-floridani</em> infections of <em>Camponotus floridanus</em> ants – the Florida zombie ants. We propose and refine hypotheses on the factors that shape infection outcomes by tracking the occurrence of fungal growth from hundreds of ant cadavers. We modeled and report these data in relation to weather, light, vegetation, and attack by mycoparasites.</p> <p class="MsoNormal">3. We investigated environmental factors that could affect the occurrence and location of newly manipulated ant cadavers. New cadavers were positively correlated with epiphytic <em>Tillandsia </em>bromeliads, canopy openness, and weather conditions (an interactive effect of temperature, humidity, and precipitation) with an increased occurrence during the sub-tropical summer. We further suggest that incident light at the individual cadaver level may reflect microhabitat choice by manipulated ants or selective pressure on cadaver maintenance for conditions improving fungal survival.</p> <p class="MsoNormal">4. We also sought to connect fungal fitness to environmental conditions. Continued fungal development of reproductive structures and putative transmission increased with moist weather conditions (interaction of humidity and precipitation) and canopy openness, while being reduced by attack by mycoparasites. Moreover, under the most open canopy conditions, we found an atypical <em>Ophiocordyceps</em> growth morphology that could represent a plastic response to conditions influenced by high light levels.</p> <p class="MsoNormal">5. Taken together, we explore general trends and the effects of various ecological conditions on host and parasite disease outcomes in the Florida zombie ant system. These insights from the field can be used to inform experimental laboratory setups that directly test the effects of biotic and abiotic factors on fungus-ant interactions or aim to uncover underlying molecular mechanisms.</p>
