Data set for "Overstory dynamics regulate the spatial variability in forest-floor CO2 fluxes across a managed boreal forest landscape"
<p>This data set is a compilation of forest stand characteristics, forest-floor environmental conditions, soil properties, ecosystem carbon stocks, and annual forest-floor CO<sub>2</sub> fluxes. The data set is composed by 3-year mean annual values obtained from biometric- and chamber-based flux measurements conducted during the period 2016–2018. Negative values of forest-floor CO<sub>2</sub> fluxes indicate carbon uptake and positive values indicate carbon release. Data were collected in 50 forest stands within the Krycklan Catchment Study (<a href="https://www.slu.se/Krycklan">https://www.slu.se/Krycklan</a>), a multi-scale long-term monitored boreal catchment spanning 68 km<sup>2</sup> in northern Sweden. Selected forest stands encompassed different soil types (sediment vs. till), dominant tree species (pine vs. spruce), and age classes (from initiation to old-growth stands).</p> <p>Variables, units, and definitions are found in the 1_metadata_Martínez-García_et_al._forest-floor_CO2_fluxes.xlsx file</p> <p>More details can be found in Martínez-García et al.

<p>This data set contains data from two Captor nodes. These are prototypes nodes that were developed at the Universitat Politècnica de Catalunya (UPC) in order to study the effects of the sensor data gathering process on the use of low-cost sensors for air quality monitoring. Specifically, the captors nodes have tropospheric ozone, nitrogen dioxide, and nitrogen monoxide electrochemical sensors. They also have a temperature and relative humidity sensor inside the box. <br> Two Captor nodes were placed in a reference station in Barcelona (Spain) for four months (January 2021 to May 2021), at a sampling frequency of 0.5 Hz. The data set contains a "readme" file with a brief description of the five files that make up the data set.</p>
Data from: PMSeeker: A Scheme for paternity marker set mining
<p>The paternity test is a genetic test that analyzes genetic characteristics (mostly molecular markers) to identify whether two individuals have a parent-child relationship. It is frequently employed in judicial identification and economic species breeding. Because a single marker's discriminability is restricted, numerous markers are typically utilized to produce an accurate result. Obviously, having an excessive number of redundant markers wastes time and resources, and adequate approaches are required to screen reduced and efficient paternity marker sets (PMS). This study established a non-redundant PMS-screening scheme based on the exhaustive algorithm and greedy algorithm. When screening PMS, the greedy algorithm selects markers based on the parental dispersity index (PDI), a uniquely defined metric that outperforms polymorphic information content (PIC) and probability of exclusion (PE). With the conjunctive use of the two algorithms the optimal solutions were found for more than 99.7% of solvable cases in three groups of random sample experiments in this study. This scheme effectively reduces the number of markers in PMS, so conserving people and experimental resources and laying the groundwork for the widespread implementation of paternity assignment technology in economic species breeding.</p>

Does hatch date set the clock? Timing of post-fledging movements for families of a colonially breeding, long-distance migratory songbird
<p><span>Factors that influence the development of migration timing in juvenile songbirds have implications for the ability of individuals to respond positively to rapid environmental changes. We investigated the impacts of nest timing on the post-fledging movement timing of juveniles and adults of a migratory songbird. We tested whether first egg date and environmental factors predicted the initiation of post-fledging stages: fledge date for juveniles, and colony departure date for both adults and juveniles. At breeding colonies of purple martin (<i>Progne subis</i>) in southern Ontario, Canada, we monitored nests to determine the date of nest initiation ('first egg date') and deployed 122 coded radio-frequency tracking tags on young and adults to determine the timing of post-fledging stages. We found that first egg date, the number of nestmates and age of parents were the main predictors of fledge date. Of these three factors, only first egg date was carried through post-fledge to influence colony departure date for juvenile birds, but this relationship weakened between first egg date and departure date. Nestmates tended to fledge together (range 0-4 days) but exhibited greater variation in colony departure timing (range 0-11 days). Further, while first egg influenced departure date, increasing variation between fledge and departure led to some birds departing breeding colonies at a younger age, suggesting in influence of local environmental factors (e.g. social or photoperiod change) in departure decisions. The timing of adult colony departure date was independent of first egg dates. In sum, our results suggest a role for 1<sup>st</sup> egg dates in setting timing of post-breeding movements, but with variation introduced between fledge and departure dates. Experimental manipulations of photoperiod in a wild setting are needed and future research should investigate whether the timing of movement driven by nesting timing, holds across the rest of migration or even the lifetime of birds. </span></p>

Data set for combined influence of food availability and agricultural intensification on a declining aerial insectivore
<p>Aerial insectivores show worldwide population declines coinciding with shifts in agricultural practices. Increasing reliance on certain agricultural practices is thought to have led to an overall reduction in insect abundance that negatively affects aerial insectivore fitness. The relationship between prey availability and the fitness of insectivores may thus vary with the extent of agricultural intensity. It is therefore imperative to quantify the strength and direction of these associations. Here we used data from an 11-year study monitoring the breeding of Tree Swallows (<em>Tachycineta bicolor</em>) and the availability of Diptera (their main prey) across a gradient of agricultural intensification in southern Québec, Canada. This gradient was characterized by a shift in agricultural production, whereby landscapes composed of forage and pastures represented less agro-intensive landscapes and those focusing on large-scale arable row crop monocultures, such as corn (<em>Zea mays</em>) or soybean (<em>Glycine max</em>) that are innately associated with significant mechanization and agro-chemical inputs, represented more agro-intensive landscapes. We evaluated the landscape characteristics affecting prey availability, and how this relationship influences the fledging success, duration of the nestling period, fledgling body mass, and wing length as these variables are known to influence the population dynamics of this species. Diptera availability was greatest within predominately forested landscapes, while within landscapes dominated by agriculture, it was marginally greater in less agro-intensive areas. Of the measured fitness and body condition proxies, both fledging success and nestling body mass were positively related to prey availability. The impact of prey availability varied across the agricultural gradient as fledging success improved with increasing prey levels within forage landscapes yet declined in more agro-intensive landscapes. Finally, after accounting for prey availability, fledging success was lowest, nestling periods were the longest, and wing length of fledglings were shortest within more agro-intensive landscapes. Our results highlight the interacting roles that aerial insect availability and agricultural intensification have on the fitness of aerial insectivores, and by extension how food availability may interact with other aspects of breeding habitats to influence the population dynamics of predators.</p>

Darwin's Hawkmoth (Xanthopan praedicta) responds to bat ultrasound at sonar-jamming rates: Acoustic data set
<p>This paper reveals that <em>Xanthopan praedicta</em> (Lepidoptera: Sphingidae) is part of the bat-moth coevolutionary dynamic. I played recordings of bat echolocation to live <em>X. praedicta</em> and found that males respond with such dense ultrasound they can likely jam bat sonar. Female <em>X. praedicta</em> and two other sphingid species do not produce ultrasonic responses.</p>
The predicted haploid gene set of the genome of Nitzschia putrida
<p>Secondary loss of photosynthesis is observed across almost all plastid-bearing branches of the eukaryotic tree of life. However, genome-based insights into the transition from a phototroph into a secondary heterotroph have so far only been revealed for parasitic species. Free-living organisms can yield unique insights into the evolutionary consequence of the loss of photosynthesis, as the parasitic lifestyle requires specific adaptations to host environments. Here we report on the diploid genome of the free-living diatom <i>Nitzschia putrida </i>(35 Mbp), a non-photosynthetic osmotroph whose photosynthetic relatives contribute ca. 40% of net oceanic primary production. Comparative analyses with photosynthetic diatoms and heterotrophic algae with parasitic lifestyle revealed that a combination of gene loss, the accumulation of genes involved in organic carbon degradation, a unique secretome and the rapid divergence of conserved gene families involved in cell wall and extracellular metabolism appear to have facilitated the lifestyle of a free-living secondary heterotroph.</p>
Data sets for Interacting effects of cold snaps, rain, and agriculture on the fledging success of a declining aerial insectivore
<p>Climate change predicts the increased frequency, duration, and intensity of inclement weather periods, such as unseasonably low temperatures (i.e., cold snaps) and prolonged precipitation. Many migratory species have advanced the phenology of important life history stages, and as a result will likely be exposed to these periods of inclement spring weather more often, thus risking reduced fitness and population growth. For declining avian species, including aerial insectivores, anthropogenic landscape changes such as agricultural intensification are another driver of population declines. These landscape changes may affect the foraging ability of food provisioning parents, and reduce the survival of nestlings exposed to inclement weather, through for example pesticide exposure impairing thermoregulation and punctual anorexia. Breeding in agro-intensive landscapes may thus exacerbate the negative effects of inclement weather under climate change. We observed that a significant reduction in the availability of insect prey occurred when daily maximum temperatures fell below 18.3°C, and thereby defined any day where the maximum temperature fell below this value as a day witnessing a cold snap. We then combined daily information on the occurrence of cold snaps and measures of precipitation to assess their impact on the fledging success of Tree Swallows (<em>Tachycineta bicolor</em>) occupying a nest box system placed across a gradient of agricultural intensification. Estimated fledging success of this declining aerial insectivore was 36.2% lower for broods experiencing four cold snap days during the 12 days post hatching period versus broods experiencing none, and this relationship was worsened when facing more precipitation. We further found that the overall negative effects of a brood experiencing periods of inclement weather was exacerbated in more agro-intensive landscapes. Our results indicate that two of the primary hypothesized drivers of many avian population declines may interact to further increase the rate of declines in certain landscape contexts.</p>

Data set for behavioural OA experiments with Caribbean Damselfish (Stegastes partitus)
<p>The neurobehavioural responses of fish exposed to ocean acidification (OA) are variable, possibly due to species-specific differences or involvement of multiple neuronal receptors. Here, we investigated behavioural responses of bicolor damselfish (Stegastes partitus) to OA and the involvement of dopamine receptors. Damselfish were exposed to control (pH 8.06; CO2 ~400 <span>μ</span>atm) or OA (pH 7.73; CO2 ~1,000 <span>μ</span>atm) seawater for five days, subjected to the open field, novel object approach, light/dark, and mirror-aggression tests, and returned to their respective aquaria. Two days later, tests were repeated upon treatment with the dopamine D1 receptor agonist SKF 38393. The D1 agonist, but not OA, altered locomotion in the open field test and boldness in the novel object approach test. Both the D1 agonist and OA increased anxiety-like behaviour in the light/dark test.</p>

Data set on: New finds of naked amoebae in the Black Sea (Ukraine)
<p>Our research identified 12 species of naked amoebae of eight morphotypes in the Black Sea (coastal zone of Zatoka village, Odessa region). In more than half of the samples, Vannella devonica, Vannella aberdonica and Thecamoeba orbis were present. The species Saccamoeba marina, Vexillifera armata, Vannella plurinucleolus, Cochliopodium gulosum, and Stenamoeba sp. were rare and infrequent in our samples. The upper layers of the bottom sediment were inhabited by all 12 species of amoebae; two layers were inhabited by S. marina, V. armata, V. devonica, V. aberdonica, Mayorella gemmifera, T. orbis, Stenamoeba sp., Acanthamoeba griffin; three layers were colonized by V. armata, V. devonica, V. aberdonica, T. orbis, Stenamoeba sp., and A. griffini. All amoebae species and their morphotypes occurred at Black Sea water temperatures of +22 ºС to +26 ºС and salinity of 15.5 ‰ to 17.6 ‰. The species V. simplex and A. griffini, which belong to the fan–shaped and acanthopodial morphotypes, respectively, were collected in samples from the Mediterranean Sea at water temperatures of +29 ºС and salinity of 37.8 ‰. The amoebas identified belong to two classes, seven orders, eight families and eight genera.</p> <p> </p>
