Grape Bunch Video Dataset with Berry Annotations and Tracking Data
<p>The dataset consists of videos of Bonarda grape bunches in a mature state. A total of 100 grape bunches were collected from five consecutive rows of the same plot at the "Finca de Sancho" located in Lavalle, Mendoza, Argentina, on March 21, 2023. Each bunch was assigned a unique identifier after collection.</p> <p>For video capture, two setups were built, referred to as setup 1 and setup 2. Each consisted of a stand to hold a bunch against a smooth white background. This background was carefully chosen to facilitate precise segmentation of the grapes in the images, ensuring more efficient and accurate object detection. Additionally, a curved structure with a 10x7 grid of QR codes was placed behind the bunch. These codes were not used in this dataset but were included for potential future studies. The setups were mounted outdoors, taking advantage of natural lighting to obtain a more realistic representation of the grape bunches. Video capture sessions were conducted over three consecutive days, lasting between 4 to 7 hours each day. The first session took place on the same day the bunches were harvested. Throughout the sessions, natural light fluctuated due to intermittent cloud cover, introducing variations in ambient lighting.</p> <p>Video recording was performed by two individuals referred to as capturer A and capturer B. The recording devices were the cameras of two smartphones, a Samsung Galaxy S20 FE and a Motorola G200. The Open Camera application (<a href="https://opencamera.org.uk/" target="_new" rel="noopener">https://opencamera.org.uk/</a>) was used, configured to automatically capture 5-second videos at a resolution of 720 pixels wide by 1280 pixels high (portrait orientation), at 30 frames per second. A fixed focal distance of 30 cm was maintained, and the white balance was manually adjusted according to the natural light variations to maintain good image quality. </p> <p>Three camera movements were defined for video capture: two systematic movements named "horizontal 180º" and "vertical 180º", and a third movement called "freestyle." The horizontal and vertical movements involved sweeping the camera from left to right and from bottom to top, respectively, while keeping the bunch centered in the frame and at a distance of approximately 30 cm. The freestyle movement consisted of random movements, maintaining the bunch centered as best as possible within the frame.</p> <p>The capture protocol was as follows:</p> <p>First, a grape bunch was placed in each setup. Capturer A at setup 1 captured five videos for each of the three defined camera movements, while capturer B did the same at setup 2. Afterward, the capturers switched positions, with capturer B taking videos at setup 1 and capturer A at setup 2. The bunches were then replaced with new ones, and the process was repeated until all 100 bunches were captured.</p> <p>As a result, the dataset contains five videos for each of the three camera movements, captured by both individuals for each of the 100 bunches. This produces a dataset consisting of 3,000 videos: 1,000 videos for each camera movement and 30 videos per bunch. </p> <p>It is worth noting that, due to the manual nature of the capture process, some variations occurred in the number of videos recorded per bunch. In some cases, 9 videos were recorded instead of 10, in one instance only 8 were captured, and in one case 11 videos were obtained. These minor discrepancies are mainly due to human error in counting the recorded videos, but they do not affect the overall quality or integrity of the dataset.</p> <p> </p> <p>The dataset also includes berry annotations for each video, provided in JSON files. These files specify, for each frame of the video, the pixel coordinates of each berry's center and the radius it occupies in the image, also in pixels. The berry detections were obtained through inference using a deep learning architecture called CircleNet, which was specifically trained for this dataset.</p> <p>In addition, the dataset contains berry tracking data, provided in CSV files. These files indicate which berries are the same across different frames of the video, through a unique berry identifier. The tracking was generated using a custom algorithm developed specifically to produce these tracks.</p> <p> </p>
Chloroplast genome assemblies and comparative analyses of commercially important Vaccinium berry crops
<p><em>Vaccinium</em> is a large genus of shrubs that includes a handful of economically important berry crops. Given the numerous hybridizations and polyploidization events, the taxonomy of this genus has remained the subject of long debate. In addition, berries and berry-based products are liable to adulteration, either fraudulent or unintentional due to misidentification of species. The availability of more genomic information could help achieve higher phylogenetic resolution for the genus, provide molecular markers for berry crop identification, and a framework for efficient genetic engineering of chloroplasts. Therefore, in this study, we assembled five <em>Vaccinium</em> chloroplast sequences representing the economically relevant berry types: northern highbush blueberry (<em>V. corymbosum</em>), southern highbush blueberry (<em>V. corymbosum</em> hybrids), rabbiteye blueberry (<em>V. virgatum</em>), lowbush blueberry (<em>V. angustifolium</em>), and bilberry (<em>V. myrtillus</em>). Comparative analyses showed that the <em>Vaccinium</em> chloroplast genomes exhibited an overall highly conserved synteny and sequence identity among them. Polymorphic regions included the expansion/contraction of inverted repeats, gene copy number variation, simple sequence repeats, indels, and single nucleotide polymorphisms. Based on their in silico discrimination power, we suggested variants that could be developed into molecular markers for berry crop identification. Phylogenetic analysis revealed multiple origins of highbush blueberry plastomes, likely due to the hybridization events that occurred during northern and southern highbush blueberry domestication.</p>

Data from: Berry production drives bottom-up effects on body mass and reproductive success in an omnivore
Obligate herbivores dominate studies of the effects of climate change on mammals, however there is limited empirical evidence for how changes in the abundance or quality of plant food affect mammalian omnivores. Omnivores can exploit a range of different food resources over the course of a year, but they often rely on seasonally restricted highly nutritious fruiting bodies during critical life stages. Brown bears Ursus arctos in Sweden are dependent on berries for fattening before entering hibernation. We used a ten-year time series to evaluate the effect of temperature and snow on annual variation in berry abundance and how this variation affected bears. We found marked interannual variation in berry production of bilberry Vaccinium myrtillus and lingonberry V. vitis-idaea, that we could attribute in part to temperature during plant dormancy and flowering and precipitation during fruit ripening. Both, autumn weights of female bears and spring weights of yearling bears increased linearly with bilberry abundance. When bilberry abundance was low, lightweight female bears had a lower reproductive success than females in better condition. This effect vanished when food abundance was above average, indicating that lightweight females could compensate for their initial weight during good bilberry years. Our study highlights the importance of considering individuals' dynamic responses to variation in food availability, which leave some more vulnerable to food shortage than others. Individual life-history heterogeneity in response to resource variation likely affects long-term population recruitment. Our findings emphasize that Scandinavian bears can be dependent on a single food resource during a critical period of the year and are therefore less resilient to environmental change than expected for an omnivore. Future climate scenarios predict ambiguous trends for weather covariates that affected crucial stages of berry phenology, preventing a clear prognosis of how climate change may affect long-term bilberry production.
Data from: Sea buckthorn berries (Hippophae rhamnoides L.) predict size and composition of a great tit population (Parus major L.).
In seasonal environments variation in food abundance in the non-breeding season is thought to affect songbird population dynamics. In a unique tit-sea buckthorn berry system we can estimate the berry abundance and both the tit consumption and population dynamics. Six hundred nest boxes were available to great and blue tits (Cyanistes caeruleus) for breeding in spring and roosting in winter. We followed the dynamics including the recapture histories of individually marked great tits from 2008-2013. In each year we estimated 1) the winter sea buckthorn berry availability, 2) an index of berry consumption in December based on the colour of the faeces of roosting birds, 3) the number of breeding great and blue tits, 4) both recapture probability and the return rate of the great tits and 5) immigration rates. December berry abundance positively predicted the number of breeding pairs of both species in the subsequent season and great tit return rates in the second half of the winter. There was support for a sex specific berry effect on the adult return rate in the great tit: female return rate was associated less strongly to berry abundance than male return rate. This skewed the sex ratio of the local breeders in the following breeding season. Intriguingly, annual berry consumption in December was not related to berry abundance, and individuals consuming more berries tended to have slightly lower return rates. Reproductive rate was not related to berry abundance. There was hardly support for a relation between immigration rates of first year breeders and berry abundance. Taken together these results imply that berry stock not only affected population size but also the population composition through sex specific exchange with the surroundings. Since population density covaried with berry abundance, density dependent effects provide an alternative explanation for the patterns observed.
Data from: Trade-offs in berry production and biodiversity under prescribed burning and retention regimes in Boreal forests
1. Green tree retention and prescribed burning are practices used to mitigate negative effects of forestry. Beside their effects on biodiversity, these practices should also promote non-timber forest products (NTFPs). We assessed: (1) how prescribed burning and tree retention influence NTFPs by examining production of bilberry Vaccinium myrtillus and cowberry; Vaccinium vitis-idaea (2) if there are synergies or trade-offs in the delivery of these NTFPs in relation to delivery of species richness, focusing on five groups of forest dwelling species. 2. We used a long-term experiment located in eastern Finland with three different harvesting treatments: clearcut-logging, logging with retention patches and unlogged, which were combined with or without prescribed burning. Eleven years after the treatment application, we scored plant cover and berry production in different microhabitats within these treatments, while species richness data for five species groups (ground-layer lichens and bryophytes, vascular plants, saproxylic beetles, pollinators – here bees and hoverflies) were collected at the stand level. 3. Logging favoured cowberry production, particularly for plants growing in the vicinity of stumps. Logging was detrimental for cover and berry production of bilberry. Retention mitigated these negative effects slightly, but cover and berry production were still substantially lower compared to unlogged forests. Prescribed burning increased cowberry production in retention patches and in unlogged forest. Bilberry production decreased with burning, except in unlogged forest where the effect was neutral. 4. No single management treatment simultaneously favoured all values - NTFPs and richness - and trade-offs among values were common. Only bilberry production and beetle diversity were higher under retention forestry, or in unlogged stands, compared to logged stands. Prescribed burning favoured many values when performed in combination with retention forestry, or in unlogged stands, but different treatment combinations favoured different species groups. 5. Synthesis and applications. Our results demonstrate that widely-applied conservation practices in managed forests are unlikely to benefit all ecosystem values everywhere. If high multi-functionality is desired, managing at a landscape scale, countering the local trade-offs among values, may be more appropriate than the stand scale conservation practices commonly practiced today.
