Effects of Energetic Electron and Proton Precipitations on Thermospheric Nitric Oxide Cooling during shock-led Interplanetary Coronal Mass Ejections
<p>Satellite measurements have revealed significant enhancement of 5.3-µm nitric oxide (NO) emission during shock-led interplanetary coronal mass ejections (ICMEs). Great discrepancies in modeled neutral density occur during these events, and may be attributed to the abnormally high NO cooling. Meanwhile, the relative significance of protons, soft electrons, and keV-electrons to NO emission is yet to be well determined. The goal of this study is to identify the contribution of electron and proton precipitations to the thermospheric NO cooling by using the Defense Meteorological Satellite Program (DMSP) data. The observed energetic electrons and protons (0.1–30.2 keV) during 36 shock-led ICME events in 2002–2010 are binned into geomagnetic grids to provide statistical distributions of the particle precipitation for polar regions. The distributions are incorporated into the Global Ionosphere-Thermosphere Model. The results show that electrons play a dominant role to NO cooling, but protons are also important and contribute to up to a quarter of NO cooling by electrons and ions combined. NO cooling enhancement during the events is proportional to the level of energy flux and is dominated by the electrons in the energy band of 1.4–3.1 keV. Both total electron content (TEC) and NO cooling enhance at the source regions, but they have different lifetime and correlation with the particle precipitations. Generally, NO cooling and TEC enhancements have a positive correlation with the precipitating energy. Cross correlation shows that particle precipitations have more direct and instantaneous impact on TEC while it takes longer for the atmosphere to heat up for cooling to proceed.</p>

Experimental manipulation of scavenger and herbivore functional role and their effects on plant communities following mass mortality events
<p>We designed an experiment to measure the relative importance of bottom-up forces (nutrient addition) and top-down forces (impairment of obligate scavenger and herbivore functional roles) generated by experimental carrion deployment to simulate mass mortality events on the local plant community. In our experimental plots, we measured changes in plant functional groups before and for three years after experimental carrion deployment. Additionally, we monitored cherrybark oak (<em>Quercus pagoda</em>) seedlings' growth and survival three years after being transplanted in the experimental plots. </p>
Corticosterone treatment results in fat deposition and body mass maintenance without effects on feeding behaviour or immunity in female lizards (Tropidurus catalanensis)
<p>In different life history stages, animals must maintain homeostasis through predictable, unpredictable and/or challenging events. Glucocorticoids (GC), hormones released in response to hypothalamus-pituitary-adrenal/interrenal (HPA/HPI) axis activation, promote various behavioural and physiological adjustments on a daily manner; and in order to restore balance, after facing stressors. When GC are elevated for an extended period and in high concentrations, characterizing a chronic exposure, it can lead to deleterious effects on animals’ physiology, such as accumulation of fat bodies, changes in feeding behaviour and suppression of immune function. We aim to elucidate the effects of chronic corticosterone exposure and body condition index (BI) in fat deposition, feeding behaviour and immune function in <em>Tropidurus catalanensis</em>’ females. Thirty animals were divided in three groups: 1. Control (no experimental procedure was performed); 2. Empty Implant (animals surgically received an empty silastic tube); and 3. CORT Implant (animals surgically received one silastic tube filled with CORT). Blood samples were collected throughout the experiment to assess CORT plasma levels, total and differential leukocyte count, bacterial killing ability (BKA), and hemagglutination titer. An immune challenge using phytohemagglutinin (PHA) was conducted to measure innate and adaptive immune response. Feeding behaviour and fat bodies were also evaluated. After implantation, CORT treated animals maintained a stable body mass through weeks of captivity, while Control and Empty Implant groups displayed weight loss. In the CORT treated animals, there was also a positive relation between BI and fat bodies, and higher fat bodies deposition when compared to groups 1 and 2. No effects of CORT treatment were observed on immune response or feeding behaviour.</p>
Effects of intraspecific competition and body mass on diet specialisation in a mammalian scavenger
<p>1. Animals that rely extensively on scavenging rather than hunting must exploit resources that are inherently patchy, dangerous, or subject to competition. Though it may be expected that scavenging species should therefore form opportunistic feeding habits in order to survive, a broad population diet may mask specialisation occurring at an individual level.</p> <p>2. To test this, we used stable isotope analysis to analyse the degree of specialisation in the diet of the Tasmanian devil, one of few mammalian species to develop adaptations for scavenging.</p> <p>3. We found that the majority of individuals were dietary specialists, indicating that they fed within a narrow trophic niche despite their varied diet as a population.</p> <p>4. Even in competitive populations, only small individuals could be classified as true trophic generalists; larger animals in those populations were trophic specialists. In populations with reduced levels of competition, all individuals were capable of being trophic specialists.</p> <p>5. Heavier individuals showed a greater degree of trophic specialisation, suggesting either that mass is an important driver of diet choice or that trophic specialisation is an efficient foraging strategy allowing greater mass gain.</p> <p>6. Devils may be unique among scavenging mammals in the extent to which they can specialise their diets, having been released from the competitive pressure of larger carnivores.</p>
