title: Reproduction ecology of an emerging fishery resource, the amphibious mudskipper Periophthalmus chrysospilos, in the Mekong Delta

description: The Gold-Spotted mudskipper Periophthalmus chrypsospilos is a potential
 aquarium pet living in the mudflats in coastal and estuarine regions, but
 populations of this mudskipper within the Mekong Delta are facing
 extirpation risks due to indiscriminate harvesting for the growing
 aquarium and food-fish trade. Consequently, this research aims to provide
 first reproductive references such as spawning type and season, length at
 first mature, batch fecundity, being used in conservation and artificially
 propagation research. Analysis results from 1,031 individuals (523 males
 and 508 females) reveal that the sex ratio of total individuals recorded
 is 1:1 (523 males and 508 females) (c2=0.22, p=0.64). The GSI values are
 found to exhibit a non-normal distribution (Shapiro-Wilk Test, NJ=0.87,
 p&lt;0.01) and change by gender (Mann-Whitney U, Z=27.04,
 p&lt;0.01), season (Z=6.17, p&lt;0.01) and site (Kruskal-Wallis H,
 c2=40.72, p&lt;0.01).  A combination of GSIs and the monthly
 appearance of mature gonads suggest that this species reproduces
 throughout the year, with a peak from July to October. This species
 exhibits sexual and spatial variation in the size at first maturity (Lm)
 as Lm is 6.2-8.6 cm in males and 6.4-7.3 cm in females. The batch
 fecundity (F=2,614 to 23,465 eggs/female) exhibits non-normal distribution
 (Shapiro-Wilk Test, NJ=0.96, p&lt;0.01) and varies with site
 (Kruskal-Wallis H, c2 =35.55, p&lt;0.01), reaching the highest point
 at Dam Doi, Ca Mau (13,336±1,279 SE) and the lowest point at Tran De, Soc
 Trang (6,654±851 SE). In addition, F is directly proportional to body size
 due to high determination values of relationships between F and fish size
 (r2&gt;0.64 for all cases). Information derived on the reproductive
 biology of this species can inform its conservation, sustainable
 exploitation, and ex-situ propagation.
description: Fishes were caught by hands for 12 months from April 2020 to
 March 2021 at four estuarine areas in the Mekong Delta. Tricaine
 methanesulfonate (10g/L) was used to anaesthetize the fish specimens which
 were washed under the tap and preserved in 5% buffered formalin before
 transport to the laboratory.

title: Seed traits matter—Endozoochoric dispersal through a pervasive mobile linker

description: Although many plants are dispersed by wind and seeds can travel long
 distances across unsuitable matrix areas, a large proportion relies on
 co-evolved zoochorous seed dispersal to connect populations in isolated
 habitat islands. Particularly in agricultural landscapes, where remaining
 habitat patches are often very small and highly isolated, mobile linkers
 as zoochorous seed dispersers are critical for the population dynamics of
 numerous plant species. However, knowledge about the quali- or
 quantification of such mobile link processes, especially in agricultural
 landscapes, is still limited. In a controlled feeding experiment, we
 recorded the seed intake and germination success after complete digestion
 by the European brown hare (Lepus europaeus) and explored its mobile link
 potential as an endozoochoric seed disperser. Utilizing a suite of common,
 rare, and potentially invasive plant species, we disentangled the effects
 of seed morphological traits on germination success while controlling for
 phylogenetic relatedness. Further, we measured the landscape connectivity
 via hares in two contrasting agricultural landscapes (simple: few natural
 and semi-natural structures, large fields; complex: high amount of natural
 and semi-natural structures, small fields) using GPS-based movement data.
 With 34,710 seeds of 44 plant species fed, one of 200 seeds (0.51%) with
 seedlings of 33 species germinated from feces. Germination after complete
 digestion was positively related to denser seeds with comparatively small
 surface area and a relatively slender and elongated shape, suggesting
 that, for hares, the most critical seed characteristics for successful
 endozoochorous seed dispersal minimize exposure of the seed to the stomach
 and the associated digestive system. Furthermore, we could show that a
 hare's retention time is long enough to interconnect different
 habitats, especially grasslands and fields. Thus, besides other seed
 dispersal mechanisms, this most likely allows hares to act as effective
 mobile linkers contributing to ecosystem stability in times of
 agricultural intensification, not only in complex but also in simple
 landscapes.

title: Raw data of eDNA quantities from an experimental study testing temperature, water masses, and fish species

description: Environmental DNA (eDNA) is a very promising approach to facilitate and
 improve the aquatic species monitoring, which is crucial for their
 management and conservation. In comparison with the plethora of monitoring
 studies in the fields, relatively few studies have focused on
 experimentally investigating the “ecology” of eDNA, in particular
 pertaining to processes influencing the detection of eDNA. The paucity of
 knowledge about its ecology hampers the use of eDNA analysis to its full
 potential. In this study, we experimentally evaluated the impact of
 several biotic and abiotic factors on the rate of production and
 degradation of eDNA. Individuals of three freshwater fish species (brown
 bullhead, tench, and yellow perch) with distinct ecology were placed in
 two types of water from the St. Lawrence River (Québec, Canada) with very
 distinct physicochemical characteristics and at three different
 temperatures. Water samples were then filtered at predetermined time
 intervals, and quantitative PCR was used to quantify the eDNA in each
 sample. We found that temperature, species, water types, and some
 interactions between these factors had a strong effect on the production
 and degradation of eDNA. The results of this study enhance our knowledge
 about the ecology of eDNA, thus improving eDNA data interpretation.

title: Attitudes Toward and Impacts of Free-roaming Dogs in Madagascar

description: Free-roaming domesticated dogs interact with humans and wildlife in ways
 that can exacerbate or mitigate existing conflict. Dogs are known to
 predate wildlife as well as domestic livestock which contributes to
 increasing human-wildlife conflict.  However, dogs can also
 mitigate conflict by protecting livestock from native predators or killing
 invasive pest species. Because attitudes toward dogs vary greatly,
 conflict often arises between humans over how to manage free-roaming dogs.
 We conducted surveys to assess attitudes toward domesticated dogs,
 behavior of dogs, and impacts on domestic and wild species. Dog owners who
 accessed Mad Dog Initiative's mobile vaccination clinics
 between 2014 and 2019 were asked to participate in the survey. 
 Mobile clinic sites were located in communities surrounding
 Andasibe-Mantadia and Ranomafana National Parks in eastern Madagascar. We
 found that people were generally favorable toward spay/neuter
 options.  Over 40% of participants reported that their dogs had
 killed wildlife and livestock predation by dogs was also common. 
 There was high spatial variation in human attitudes, dog behavior, and
 predation rates.
description: The dataset was collected from surveys of pet owners between 2014
 and 2019. Here we have a subset of only dog owners with additional
 variables to record GPS location, year, region, and distance to national
 park as calculated in GIS software. We also converted the multiple answer
 question of reason for owning dogs into separate dummy
 variables.

title: Male meadow vole scent marking 1 rival odor context

description: Meadow voles (Microtus pennsylvanicus) rely on olfactory communication,
 such as scent marking, to find and secure mating opportunities during the
 breeding season. Scent marks, and odors in general, provide information
 about the donors and persists in the environment for extended periods,
 allowing a wide audience. Whether a vole responds to another scent
 mark(s), or odor(s), depends on the social context and the information the
 odor provides about the donor(s). Therefore, we examined if male scent
 marking towards a social odor or female meadow voles is influenced by
 information present or previously encountered based on contextual
 differences in the social odor. We presented males with two odor
 associations of a male with a female with contextual differences in the
 age of the rival. We tested male scent marking with both the odors
 present, current information, and with the females from the social
 information, prior information. It was found that rival male age did not
 affect the scent marking behavior of males towards a social odor or female
 voles. Rival male age also did not affect preference as males did not show
 a preference for either female. The lack of an effect may lie in the
 properties of scent marks and the natural history of meadow voles during
 the breeding season. The odor of an individual rival may not represent a
 strong enough competitional threat to influence a signaler’s decisions,
 but the association could still provide the signaler with valuable
 information about which females are consider high-quality.
description: Data was analyzed using R version 4.0.5 in Rstudio version
 1.4.1106. Scent marking analysis for the odor present
 data (control and two male odors) we used a generalized liner mixed model
 with a negative binomial distribtion with the fixed factors of side of the
 sides of the apparatus and the random factor of the individual
 male. Scent marking analysis for the female present
 data we used a generalized linear mixed model with a zero inflated
 distribution with the fixed factors of side of the sides of the apparatus
 and the random factor of the individual male.
 Preference analysis for the females present data we used a one
 sample t-test. Prefernces were calculated by taking the total time spent
 near the female whose odor had associated with a younger male divided by
 the total time spent near each female. Packages used
 were lme4, glmmTMB and MASS

title: Multicamera synthetic dataset of crashes at the intersection

description: This dataset is a synthetic image dataset generated using Unreal Engine 5 and is designed to simulate traffic accidents at a road intersection, with a focus on car–car and car–pedestrian collisions. The dataset is intended for research on deep learning–based methods for traffic accident detection and prediction, particularly in the context of traffic surveillance applications.

The dataset is based on a custom-built 3D intersection model inspired by a real-world intersection located in the Czech Republic. It contains four distinct scenes, where each scene represents a different part or viewpoint of the intersection. The scenes were created specifically for this dataset to provide realistic yet fully controlled traffic scenarios.

For each scene, the dataset includes sequences depicting normal traffic behavior without any collisions, as well as sequences containing collision events. These collision scenarios include both vehicle–vehicle and vehicle–pedestrian accidents.

In total, the dataset contains 2,192 images, of which 1,063 images represent normal traffic conditions and 1,129 images represent anomalous traffic with collision events.

All images in the dataset are annotated with ground truth bounding boxes and corresponding class labels, enabling their direct use for supervised learning tasks such as object detection, tracking, and accident analysis.

The dataset is provided to foster research and development of methods for automatic traffic collision detection, accident prediction, and anomaly detection in traffic surveillance systems.

Warning: The dataset contains synthetic images depicting traffic collisions involving vehicles and pedestrians. Although the data is artificially generated, some images may be disturbing or uncomfortable for certain viewers.

This dataset has been created as part of the SENDER project by Faculty of Electrical Engineering and Communication at Brno University of Technology (BUT) and Yunex s.r.o (part of Yunex Traffic) funded by Technology Agency of Czech Republic (TAČR).

title: Heritable variation in host quality as measured through an ectoparasite's performance

description: Obligate parasites need one or more hosts to complete their life cycle.
 However, hosts might show intraspecific variation in quality with respect
 to the parasites themselves, thus affecting on-host and off-host parasite
 performance. High heritability in host quality for the parasite may
 therefore exert long-lasting selective pressures on the parasite and
 influence host–parasite coevolution. However, the amount of variation and
 heritability in host quality are unknown for most parasite species,
 especially in wild populations of hosts. Both measures were estimated in a
 wild-caught bird Parus major that was experimentally infested by two
 developmental stages (larva and nymph) of a ectoparasite (the tick Ixodes
 arboricola). We examined variation in host quality through variation in
 tick performance, namely the on-host performance (attachment success,
 feeding time, engorgement weight and feeding success) and the off-host
 performance (moulting time, moulting success and overall survival). Herein
 we also investigated the influence on tick performance of host traits
 linked with the bird’s life history and physiology such as body condition,
 sex, age and haematocrit. By correlating tick performance variables
 between larvae and nymphs feeding on the same bird at different times, we
 found a significant correlation in attachment success, suggesting
 consistent among-host variation for this performance measure, but no
 significant larva-nymph correlations for the other tick variables. Animal
 models relating tick performance variables to the host pedigree showed a
 strong heritable signal for host quality as measured through tick feeding
 time, and lower but substantial estimates in other performance variables.
 With regard to the host traits, feeding success and survival of tick
 larvae were lower on female birds, and nymphal survival was higher on
 older birds. Larval feeding time was negatively  correlated with
 host haematocrit. This is one of the first studies showing consistent
 intraspecific variation and heritability of host quality for a multistage
 ectoparasite.

title: AI leader disclosure

description: As artificial intelligence (AI) increasingly occupies supervisory and leader roles in organizations, questions arise regarding how employees respond to AI leaders, particularly with respect to trust and job satisfaction. Although prior research has largely examined AI leadership at a conceptual level, little is known about how followers react when first encountering an AI leader. This study examines whether explicit AI leader disclosure fosters follower trust and, in turn, enhances follower job satisfaction. Drawing on social exchange theory, we employed an experimental vignette methodology with working adults who were randomly assigned to either an AI leader disclosure condition or a control condition. After reading the vignette, participants completed established and adapted measures of follower trust and job satisfaction. Results show that follower trust fully mediates the relationship between AI leader disclosure and job satisfaction. Although the direct effect of AI leader disclosure on job satisfaction was non-significant, the indirect effect through follower trust was significant. These findings suggest that transparent disclosure of an AI leader’s identity can support trust formation, which is critical for positive employee experiences. The study contributes to the emerging literature on AI in leadership by introducing AI leader disclosure as a relational practice and identifying follower trust as a key mechanism linking AI leaders to employee job satisfaction.

title: Tolerant pattern recognition: Evidence from phonotactic responses in the cricket Gryllus bimaculatus (de Geer)

description: When the amplitude modulation of species-specific acoustic signals is
 distorted in the transmission channel, signals become difficult to
 recognise by the receiver. Tolerant auditory pattern recognition systems,
 which after having perceived the correct species-specific signal
 transiently broaden their acceptance of communication signals, would be
 advantageous for animals as an adaptation to the constraints of the
 environment. Using a well-studied cricket species, Gryllus bimaculatus, we
 analysed tolerance in auditory steering responses to non-attractive “Odd”
 and “Silent” chirps by employing a fine-scale open-loop trackball system.
 Odd chirps on their own did not elicit a phonotactic response. However,
 when inserted into a calling song pattern with attractive Normal chirps,
 the females’ phonotactic response towards these patterns was significantly
 larger than to patterns with Silent chirps. Moreover, females actively
 steered towards non-attractive Odd chirps when these were presented within
 a sequence of attractive chirps. Our results suggest that crickets employ
 a tolerant pattern recognition system that, once activated, transiently
 allows responses to non-attractive sound patterns. As pattern recognition
 modulates how crickets process non-attractive acoustic signals, the
 finding is also relevant for the interpretation of two-choice behavioural
 experiments.
description: Data were collected from
 an open loop trackball set up, which was manipulated by a tethered female
 cricket placed on top. Trackball movements were recorded using software
 designed in LabView 5.01 (National Instruments, London UK). The steering
 velocity of the crickets was calculated based on the output of the optical
 sensor and the lateral deviation over each presentation was obtained by
 integrating the velocity data. These were pooled to obtain a measure for
 the phonotactic response over a one-minute window  Experiment 1 and 2 feature
 lateral steering deviations (in mm) to chirp types over the course of a
 minute. Experiment 3 features change in steering velocity (mm) between the
 onset of a chirp and peak response.

title: DNA metabarcoding reveals broadly overlapping diets in three sympatric North American hummingbirds

description: Hummingbirds, a highly diverse avian family, are specialized vertebrate
 pollinators that feed upon carbohydrate-rich nectar to fuel their fast
 metabolism while consuming invertebrates to obtain protein. Previous work
 has found that morphologically diverse hummingbird communities exhibit
 higher diet specialization on floral resources than morphologically
 similar hummingbird communities. Due to the difficulties of studying avian
 diets, we have little understanding whether hummingbirds show similar
 patterns with their invertebrate prey. Here, we use DNA metabarcoding to
 complete an analysis of floral and invertebrate diets of three species of
 sympatric North American hummingbirds. We collected fecal samples from 89
 Anna’s (Calypte anna), 39 Black-chinned (Archilochus alexandri), and 29
 Calliope (Selasphorus calliope) hummingbirds in urban and rural localities
 as well as across an elevational gradient from sea level to 2500 meters
 above sea level in California, USA. We found hummingbirds showed high
 dietary overlap in both invertebrate and plant resources, with few
 invertebrate and plant families common to most individuals and many
 families found in only a few individuals. Chironomidae was the most common
 invertebrate family across all species, and Rosaceae and Orobanchaceae
 were the most common plant families. Anna’s Hummingbirds had significantly
 higher invertebrate diet diversity than Black-chinned Hummingbirds when
 found at the same sites, but we found no difference in plant diet
 diversity among any of the three species. Hummingbirds in urban sites had
 higher plant diet diversity than in rural sites, but we found no effect of
 elevation on dietary richness. Our study shows how DNA metabarcoding can
 be used to non-invasively investigate previously unknown life-histories of
 well-studied birds, lending insight to community structure, function, and
 evolution.
description: We captured hummingbirds in California, USA and collected fecal
 samples. We used DNA metabarcoding to examine the floral and invertebrate
 diet items within each fecal sample. Here we present the metadata
 regarding each hummingbird, including species, date and location of
 capture, morphometrics, and total diet richness. Our second dataset is a
 spreadsheet showing each hummingbird (identified by a unique ID) and a
 precense/absence list of if a specific diet item was present in the
 hummingbirds fecal sample.
