Living in the litter: The influence of tree leaf litter on wetland communities, 2006.
Empirical research in streams has demonstrated that terrestrial subsidies of tree leaf litter infl uence multiple community factors including composition, diversity and growth of individuals. However, little research has examined the importance of tree litter species on wetlands, which are ubiquitous across the landscape and serve as important habitats for a unique and diverse community of organisms. Using outdoor mesocosms, we assessed the impact of 12 litter monocultures and three litter mixtures (from both broadleaf and conifer trees) on pond communities containing gray tree frog tadpoles Hyla versicolor , periphyton, phytoplankton and zooplankton. We found that leaf litter species had substantial and diff erential impacts on all trophic groups in the community including eff ects on algal abundance, zooplankton density and amphibian growth. In many instances, patterns of responses were specifi c to individual litter species yet some responses, including both pH values and periphyton biomass, were generalizable to broad taxonomic groups. In addition, while most responses of litter mixtures were additive, we found evidence for antagonistic eff ects of litter mixing among responses of periphyton and amphibian body mass. Our results highlight the potential impact of human and naturally driven changes in forest composition on wetland communities through associated changes in leaf litter.

Tree regeneration after fire: Delta 1994 burn surveys, live seedling counts, by species
Data for this study were collected in 2001 and 2002 by Jill Johnstone (University of Alaska Fairbanks) and Eric Kasischke (University of Maryland). Sites were located within the perimeter of the 1994 burn southeast of Delta Junction Alaska, USA, bordering the Alaska Highway to the North and the Gerstle River to the West. Sites were selected from satellite classifications prepared by Eric Kasischke to represent different levels of burn severity and post-fire vegetation canopy greenness (NDVI). Site selection was constrained by road access, and only areas where all trees had been killed by the fire were selected. At each site, a central point was located in an area of visually homogeneous vegetation. Five parallel transects, each 50 m long, were laid out as follows: 1) the first transect started at the central point and followed a randomly-selected compass direction, 2) two additional transects were established parallel to the first, but at a random distance from the central transect up to 25 m distant. Vegetation was sampled in a 2-m wide belt centered on each transect, and soil samples were made at intervals along the transect line. Vegetation measurements included: a) basal diameters of all pre-fire trees greater than 1.3 m in height, b) counts of all post-fire tree seedlings, and c) basal diameters of tree seedlings and willows, measured in a randomly chosen 5x2 m portion of each transect. General notes were made on visual percent cover of different vegetation growth forms at the site. Destructive measurements of tree seedlings and willows made in 2001 were used to develop allometric equations to predict dry biomass from basal diameter. Measurements of soil organic layer depth were made at 5 m intervals with the use of a spade to excavate small chunks of sod. At one randomly-selected sample point per transect, a 10x10 cm sample of the organic layer was collected for bulk density measurements. Bulk density samples were dried in a 60degC oven for 48 hours and then w
Living Field Laboratory at the Kellogg Biological Station, Hickory Corners, MI (1992 to 2012)
Dataset Abstract The Living Field Laboratory is a long-term rotation study established in 1993 under the direction of Emeritus Professor Dr. Richard Harwood to evaluate the benefits of cover crops (as green manure) and/or the addition of composted dairy manure in two integrated systems compared to a conventional and an organic system. The LFL accommodates every entry point of the crop rotation each year and has a factorial design that allows for the comparison of a number of interactions. These interactions include: differences in N management, rotation effects, and cover crops. From 1993 through 2005, the rotation consisted of corn (Zea mays L.)/corn/soybean (Glycine max)/wheat (Triticum aestivum) vs. continuous corn. During this period, crimson clover (Trifolium incarnatum L.) was seeded to 1st yr. corn, 2nd yr corn was in rye grass (Lolium multiflorum), soybean had no cover, and red clover (Trifolium pretense L.) was frost-seeded into wheat. In 2006, under the direction of Dr. Sieglinde Snapp and through consultation with a farmer advisory group, the rotation was shortened to a 3 yr rotation of corn/soybean/wheat vs. continuous corn. The remaining plot in each management system was converted to a 2 yr rotation of corn/soybean. Cereal rye (Secale cereale) is now planted after corn regardless of crop rotation. Cereal rye follows soybean in the 2-yr rotation. Red clover is frost-seeded into wheat. The management systems are: Conventional, Integrated Fertilizer and Integrated Compost. Weed management is identical across systems, and nitrogen fertilizer management adjusted to take into account soil N availability and balance nitrogen inputs across treatments. The cover crop is present as a split plot (plus minus) within each system. The split-plot cover crop treatment was established in 1993 in Integrated Fertilizer and in Integrated Compost, while the split-plot cover crop treatment was established 14 years later in 2007 in the Conventional treatment, to allow a comp

Data from: Early-life exposure to artificial light at night elevates physiological stress in free-living songbirds
<p>Artificial light at night (ALAN) can disrupt adaptive patterns of physiology and behavior that promote high fitness, resulting in physiological stress and elevation of steroid glucocorticoids (corticosterone, CORT in birds). Elevated CORT may have particularly profound effects early in life, with the potential for enduring effects that persist into adulthood. Research on the consequences of early-life exposure to ALAN remains limited, especially outside of the laboratory, and whether light exposure affects CORT concentrations in wild nestling birds particularly remains to be elucidated. We used an experimental setup to test the hypothesis that ALAN elevates CORT concentrations in developing free-living birds, by exposing nestling great tits (Parus major) to ALAN inside nest boxes. We measured CORT in feathers grown over the timeframe of the experiment (7 nights), such that CORT concentrations represent an integrative metric of hormone release over the period of nocturnal light exposure, and of development. We also assessed the relationships between feather CORT concentrations, body condition, nestling size rank and fledging success. In addition, we evaluated the relationship between feather CORT concentrations and telomere length. Nestlings exposed to ALAN had higher feather CORT concentrations than control nestlings, and nestlings in poorer body condition and smaller brood members also had higher CORT. On the other hand, telomere length, fledging success, and recruitment rate were not significantly associated with light exposure or feather CORT concentrations. Results indicate that exposure to ALAN elevates CORT concentrations in nestlings, which may reflect physiological stress. In addition, the organizational effects of CORT are known to be substantial. Thus, despite the lack of an effect on telomere length and survivorship, elevated CORT concentrations in nestlings exposed to ALAN may have subsequent impacts on later-life fitness and stress sensitivity.</p>
Data from: Live fast, die old: oxidative stress as a potential mediator of an unexpected life-history evolution
Intraspecific latitudinal patterns in life history are well documented, yet underlying mechanisms of such patterns are poorly understood. To advance our insights in the evolution of latitudinal differences in two key traits, growth rate and lifespan, we evaluated the potential costs of rapid growth in terms of reduced adult lifespan, and the mediatory role of oxidative stress. We studied latitudinal differentiation in routine and experimentally increased (compensatory) larval growth rates, and in adult lifespan under common garden conditions in low- and high-latitude populations of the damselfly <i>Ischnura elegans</i>. The low-latitude populations showed not only higher routine growth rates but also a stronger compensatory growth response after a transient food shortage compared to the high-latitude populations. In contrast with a trade-off scenario, adults of the faster growing low-latitude populations lived longer, had higher levels of antioxidant enzymes, and tended to experience lower oxidative damage. Importantly, these latitudinal patterns were largely mirrored at the treatment level, where experimentally induced compensatory growth rates were associated with neither oxidative damage nor shorter adult lifespans. Moreover, individuals with a higher growth rate after the transient food shortage did not have shorter adult lifespans or higher oxidative damage, but instead showed a stronger antioxidant defense. Our data indicate that an overcompensatory, hormetic response in antioxidant defense, potentially induced by the higher routine growth rates, resulting in less oxidative damage may underlie these unexpected growth-lifespan patterns. Our results highlight the added value of incorporating oxidative stress physiology, and the need to consider multivariate trade-offs in which animals optimize multiple traits, when studying life-history evolution.
Data from: Live-cell single particle imaging reveals the role of RNA polymerase II in histone H2A.Z eviction
<p>The H2A.Z histone variant, a genome-wide hallmark of permissive chromatin, is enriched near transcription start sites in all eukaryotes. H2A.Z is deposited by the SWR1 chromatin remodeler and evicted by unclear mechanisms. We tracked H2A.Z in living yeast at single-molecule resolution, and found that H2A.Z eviction is dependent on RNA Polymerase II (Pol II) and the Kin28/Cdk7 kinase, which phosphorylates Serine 5 of heptapeptide repeats on the carboxy-terminal domain of the largest Pol II subunit Rpb1. These findings link H2A.Z eviction to transcription initiation, promoter escape and early elongation activities of Pol II. Because passage of Pol II through +1 nucleosomes genome-wide would obligate H2A.Z turnover, we propose that global transcription at yeast promoters is responsible for eviction of H2A.Z. Such usage of yeast Pol II suggests a general mechanism coupling eukaryotic transcription to erasure of the H2A.Z epigenetic signal.</p>
Life history data for longer-lived tropical songbirds reduce breeding activity as they buffer impacts of drought
<p><span>Droughts are expected to increase in frequency and severity with climate change. Population impacts of such harsh environmental events are theorized to vary with life history strategies among species. However, existing demographic models generally do not consider behavioral plasticity that may modify the impact of harsh events. Here we show that tropical songbirds in the New and Old World reduced reproduction during drought, with greater reductions in species with higher average long-term survival. Large reductions in reproduction by longer-lived species were associated with higher survival during drought than pre-drought years in Malaysia, whereas shorter-lived species maintained reproduction and survival decreased. Behavioral strategies of longer-lived, but not shorter-lived, species mitigated the effect of increasing drought frequency on long-term population growth. Behavioral plasticity can buffer the impact of climate change on populations of some species, and differences in plasticity among species related to their life histories are critical for predicting population trajectories.</span></p>
