Capacity of the medullary cavity of tibia and femur for intra-bone marrow transplantation in mice
<p>Intra-bone marrow transplantation (IBMT) has been adapted for mouse models to improve the seeding efficiency of transplanted human leukemic stem cells. Commonly used injection volumes for IBMT into the tibia differ between 10 and 40 µL even though considerable amounts of injected cells leak into the blood circulation immediately after injection. Injection of 3 µL trypan blue into the tibia of dead BALB/c mice showed staining in large vessels of hind limbs, even without supporting circulation. We therefore tested the effective capacity of the medullary cavity of dissected tibiae and femora of different mouse strains by bioluminescence imaging after injection of luciferase expressing cells. Cell leakage was already observed at 3 µL of injection volume and the measured emission rate increased significantly when 5 and 10 µL of volume with the same cell concentration were injected. Surprisingly, increasing injection volumes containing constant cell amounts resulted in comparable emission rates, suggesting a similar amount of leaked and absorbed cells independent of the injection volume. However, the absorption of a specific amount of injected cells could not be confirmed since the ratio of leaked to absorbed cells was similar between IBMT that were performed with a constant injection volume containing either low or high cell amounts. In summary, for optimal cell transplantation via IBMT we suggest to inject a highly concentrated cell suspension with a maximum injection volume of 3 µL.</p>

Migratory cavity nesters (Ficedula hypoleuca) incur fitness costs from ecological traps
<p><span>When selecting a habitat for breeding and offspring rearing, it is optimal for organisms to select a stable habitat with high amounts of quality resources. However, organisms may inadvertently select a habitat for breeding that would initially appear preferential and healthy, but may in reality be detrimental to parent and/or offspring fitness. Such ecological traps may even be the result of human habitat modification and conservation efforts. In this study, we tested whether migratory European pied flycatcher (</span>Ficedula hypoleuca) offspring cavity-nesting in patches of forest affected by outbreaks of the great web-spinning sawfly (Acantholyda posticalis<span>) incurred fitness detriments characteristic of ecological traps when compared to flycatchers that nested in patches of unaffected forest. Outbreaking sawfly larvae overconsume Scots pine (Pinus sylvestris) needles and substrate, which decreases resource availability directly and indirectly–through cascading effects–for birds inhabiting the forest. In installing nest boxes to attract breeding pairs and potentially combat the outbreak, we found that flycatchers inhabiting areas of sawfly outbreaks had similar clutch sizes to pairs breeding in healthy forest patches. Contrarily, the fledgling number and body condition were significantly lower for those nesting in the damaged forests. Though larvae serve as the primary food source for nestlings, the forest patches damaged by sawflies also had lower larval biomass from rapid resource decline due to overconsumption. In provisioning nest boxes for migrating flycatcher pairs in forest patches that were subsequently impacted by a pest insect outbreak, an ecological trap arose for those pairs choosing to nest in what appeared to be an unaffected forest at first. Given the inability of breeding pairs to distinguish habitat quality on initial inspection, we suggest that nest boxes be used with caution in areas with unstable habitat conditions when attracting migratory birds given the trends of their declining global numbers.</span></p>

Data from: Identifying demographic and environmental drivers of recruitment and population growth in a cavity nesting sea duck population
Traits with the greatest proportional effects on fitness are typically conserved (Stearns 1992), and traits with larger temporal variation frequently play a dominant role in population dynamics (Cooch et al. 2001). We examined recruitment patterns and population growth in Common Goldeneyes (Bucephala clangula; hereafter goldeneye), using Pradel mark-recapture models from a long-term nest box study (1997-2010). Our objectives were to estimate recruitment (f) and population growth (λ) relative to recruitment origin group (in-situ or unknown), investigate environmental and density dependent effects on these parameters, and evaluate potential immigration patterns. We detected group-specific differences for f (in-situ: 0.47± 0.13 SE, unknown: 0.31 ± 0.04), and the proportion of boxes occupied by goldeneyes the year prior to recruitment had a significant negative effect on recruitment for the in-situ group (β = -1.04; 85% CI -1.29, -0.78), and a positive effect for the unknown group (β = 0.45; 85% CI 0.30, 0.61). The negative box occupancy effect in the year prior to recruitment, when in-situ yearling goldeneyes prospect for potential nest sites, suggests that local nesting densities may limit recruitment of locally hatched females. We identified two competitive models for λ, which averaged 1.04 ± 0.03 and included interactions between recruitment origin group and a linear temporal trend, and the proportion of ducklings marked two years prior. By evaluating all levels of marking effort on λ, we determined that even if all hatched ducklings were marked in a given year, the resulting in-situ λ was consistently lower than all observed population-level λs during the study, indicating that individuals produced outside of study area nest boxes contributed to λ. Though female goldeneyes are considered highly philopatric, our results suggest that female natal and breeding dispersal may be more prevalent than previously thought, and the spatial scale at which these processes occur requires further investigation.
