title: Recognition of conspecific immunological status in a neotropical paper wasp

description: Host immune activation is common under a pathogen invasion. This
 physiological response can promote changes in body surface compounds, thus
 providing chemical cues related to health that might be useful to
 conspecifics. By recognizing the current immunological status of social
 partners, individuals can modulate their behavior to minimize the risk of
 infection. Tegument wounding, an immune elicitor, is a required step for
 many parasites to become established in a host. By using the neotropical
 eusocial paper wasp Mischocyttarus metathoracicus as a model organism, we
 first performed a lure presentation experiment in the field to test if
 wasps discriminate conspecific immunological status (experimentally
 manipulated by wounding) during on-nest social interactions. Then, we
 performed gas chromatography-mass spectrometry analyses to test if
 immunostimulation by wounding alters the wasps’ cuticular hydrocarbon
 profile. We found that wasps reduce the duration of aggressive physical
 contact when interacting with wounded lures, despite displaying a similar
 frequency of inspective and aggressive behaviors toward both the wounded
 and the control lures. Besides, we found a subtle increase in a single
 cuticular hydrocarbon in the wounded wasps. Thus, wasps recognize
 conspecific immunological status, likely by chemical cues, and modulate
 their behavior in order to defend the colony against intruders while
 minimizing the personal risk of infection.

title: Data for: A spatially explicit trait-based approach uncovers changes in assembly processes under warming

description: The re-assembly of plant communities during climate warming depends on
 several concurrent processes. Here we present a novel framework that
 integrates spatially explicit sampling, plant trait information and a
 warming experiment to quantify shifts in these assembly processes. By
 accounting for spatial distance between individuals, our framework allows
 separation of potential signals of environmental filtering from those of
 different types of competition. When applied to an elevational transplant
 experiment in the French Alps, we found common signals of environmental
 filtering and competition in all communities. Signals of environmental
 filtering were generally stronger in alpine than in subalpine control
 communities, and warming reduced this filter. Competition signals depended
 on treatments and traits: Symmetrical competition was dominant in control
 and warmed alpine communities, while hierarchical competition was present
 in subalpine communities. Our study highlights how distance dependent
 frameworks can contribute to a better understanding of transient
 re-assembly dynamics during environmental change.

title: Data for: No physiological costs of dual sequestration of chemically different plant toxins in the milkweed bug Spilostethus saxatilis (Heteroptera: Lygaeidae)

description: Many herbivorous insects not only cope with plant toxins but also
 sequester them as a defense against predators and parasitoids.
 Sequestration is a product of the evolutionary arms race between plants
 and herbivorous insects and has been hypothesized to incur physiological
 costs due to specific adaptations required. Contradictory evidence about
 these costs exists for insects sequestering only one class of toxin, but
 very little is known about the physiological implications for species
 sequestering structurally different classes of compounds. Spilostethus
 saxatilis is a milkweed bug belonging to the cardenolide-sequestering
 heteropteran subfamily Lygaeinae (Heteroptera: Lygaeidae) that has shifted
 to the colchicine-containing plant Colchicum autumnale, a resource of
 chemically unrelated alkaloids. Using feeding-assays on artificial diet
 and chemical analysis, we assessed whether S. saxatilis is still able to
 sequester cardenolides apart from colchicine and related metabolites
 (colchicoids), and tested the effect of (1) either a natural cardenolide
 concentration (using ouabain as a model compound) or a natural colchicine
 concentration, (2) an increased concentration of both toxins, and (3)
 seeds of either Asclepias syriaca (cardenolides) or C. autumnale
 (colchicoids) on a set of life-history traits. For comparison, we assessed
 the same life-history traits in the milkweed bug Oncopeltus fasciatus
 exposed to cardenolides only. Although cardenolides and colchicoids have
 different physiological targets (Na+/K+-ATPase vs tubulin) and thus
 require different resistance traits, chronic exposure and sequestration of
 both isolated toxins caused no physiological costs such as reduced growth,
 increased mortality, lower fertility, or shorter adult life span in S.
 saxatilis. Indeed, an increased performance was observed in O. fasciatus
 and an according trend was found in S. saxatilis when feeding on isolated
 ouabain and isolated colchicine, respectively. Positive effects were even
 more pronounced when insects were provided with natural toxic seeds (i.e.
 C. autumnale for S. saxatilis and A. syriaca for O. fasciatus), especially
 in O. fasciatus. Our findings suggest, that S. saxatilis can sequester two
 chemically unrelated classes of plant compounds at a cost-free level, and
 that colchicoids may even play a beneficial role in terms of fertility.

title: Urban tree pests can support biological control services in landscape shrubs

description: Scale insects are common tree pests in urban ecosystems. Although severe
 scale infestations can worsen tree condition, trees can tolerate moderate
 scale densities. Scale insects are prey for many arthropod natural enemies
 that also feed on plant pests throughout urban landscapes. Because
 scale-infested trees support natural enemy communities, they may support
 biological control services on nearby plants and function analogously to
 banker plants in greenhouse production systems. In this study, we tested
 if sentinel insect prey were more likely to be removed on shrubs below
 scale-infested trees compared to scale-uninfested trees. We conducted
 several biological control experiments from 2019–2021 using fruit flies,
 aphids, and caterpillars in potted and planted holly shrubs below
 scale-infested and scale-uninfested oak trees. We found that caterpillars
 in potted shrubs and fruit flies in planted landscape shrubs were more
 likely to be removed underneath scale-infested trees compared to
 scale-uninfested trees. Caterpillars were also more likely to be removed
 from landscape Ilex vomitoria shrubs compared to I. cornuta shrubs. In all
 other experiments, we found no effect of scale infestation status or shrub
 species on prey removal. Our results suggest that scale-infested trees can
 support biological control services in shrubs below them but that this
 effect can vary depending on prey and shrub species. The natural enemy
 communities in urban trees and shrubs appear to be linked and tolerating
 tree pests can favor conservation biological control services in urban
 landscapes.

title: Data from: Body condition changes at sea: Onboard calculation and telemetry of body density in diving animals

description: The ability of marine mammals to accumulate sufficient lipid energy
 reserves is vital for mammals' survival and successful reproduction.
 However, long-term monitoring of at-sea changes in body condition,
 specifically lipid stores, has only been possible in elephant seals
 performing prolonged drift dives (low-density lipids alter the rates of
 depth change while drifting). This approach has limited applicability to
 other species. Using hydrodynamic performance analysis during transit
 glides, we developed and validated a novel satellite-linked data logger
 that calculates real-time changes in body density (∝lipid stores). As
 gliding is ubiquitous amongst divers, the system can assess body condition
 in a broad array of diving animals. The tag processes high sampling-rate
 depth and 3-axis acceleration data to identify 5 s high pitch angle glide
 segments at depths &gt;100 m. Body density is estimated for each glide
 using gliding speed and pitch to quantify drag versus buoyancy forces
 acting on the gliding animal. We used tag data from 24 elephant seals
 (Mirounga spp.) to validate the onboard calculation of body density
 relative to drift rate. The new tags relayed body density estimates over
 200 days and documented lipid store accumulation during migration with
 good correspondence between changes in body density and drift rate. Our
 study provided updated drag coefficient values for gliding (Cd,f = 0.03)
 and drifting (Cd,s = 0.12) elephant seals, both substantially lower than
 previous estimates. We also demonstrated post-hoc estimation of the
 gliding drag coefficient and body density using transmitted data, which is
 especially useful when drag parameters cannot be estimated with sufficient
 accuracy before tag deployment. Our method has the potential to advance
 the field of marine biology by switching the research paradigm from
 indirectly inferring animal body condition from foraging effort to
 directly measuring changes in body condition relative to foraging effort,
 habitat, ecological factors, and anthropogenic stressors in the changing
 oceans. Expanding the method to account for diving air volumes will expand
 the system's applicability to shallower-diving (&lt;100 m)
 species, facilitating real-time monitoring of body condition in a broad
 range of breath-hold divers.

title: Data and software for: Temporal novelty detection and multiple timescale integration drive Drosophila orientation dynamics in temporally diverse olfactory environments

description: To survive, insects must effectively navigate odors plumes to their
 source. In natural plumes, turbulent winds break up smooth odor regions
 into disconnected patches, so navigators encounter brief bursts of odor
 interrupted by bouts of clean air. The timing of these encounters plays a
 critical role in navigation, determining the direction, rate, and
 magnitude of insects’ orientation and speed dynamics. Disambiguating the
 specific role of odor timing from other cues, such as spatial structure,
 is challenging due to natural correlations between plumes’ temporal and
 spatial features. Here, we use optogenetics to isolate temporal features
 of odor signals, examining how the frequency and duration of odor
 encounters shape the navigational decisions of
 freely-walking Drosophila. We find that fly angular velocity
 depends on signal frequency and intermittency – fraction of time signal
 can be detected – but not directly on durations. Rather than switching
 strategies when signal statistics change, flies smoothly transition
 between signal regimes, by combining an odor offset response with a
 frequency-dependent novelty-like response. In the latter, flies are more
 likely to turn in response to each odor hit only when the hits are sparse.
 Finally, the upwind bias of individual turns relies on a filtering scheme
 with two distinct timescales, allowing rapid and sustained responses in a
 variety of signal statistics. A quantitative model incorporating these
 ingredients recapitulates fly orientation dynamics across a wide range of
 environments and shows that temporal novelty detection, when combined with
 odor motion detection, enhances odor plume navigation.

title: Plant–hummingbird pollination networks exhibit limited rewiring after experimental removal of a locally abundant plant species

description: In this study, we simulated the local extinction of a
 hummingbird-pollinated understory plant, Heliconia tortuosa, from tropical
 forest fragments using a replicated Before-After-Control-Impact (BACI)
 experimental design while quantifying plant-hummingbird interactions
 through two parallel techniques: pollen collected from individual
 hummingbirds (‘pollen networks’, created from &gt;300 pollen samples)
 and observations of hummingbirds visiting focal plants (‘camera networks’,
 created from &gt;19,000 observation hours). Each response
 variable was measured during each experimental period (pre and post) in
 sites with and without H. tortuosa removal (treatment and control).

title: Data for: EMBER multi-dimensional spectral microscopy enables quantitative determination of disease- and cell-specific amyloid strains

description: In neurodegenerative diseases, proteins fold into amyloid structures with
 distinctconformations (strains) that are characteristic of different
 diseases. However, thereis a need to rapidly identify amyloid
 conformations in situ. Here, we use machinelearning on the full
 information available in fluorescent excitation/emission spec-tra of
 amyloid-binding dyes to identify six distinct different conformational
 strainsin vitro, as well as amyloid-β (Aβ) deposits in different
 transgenic mouse models. OurEMBER (excitation multiplexed bright emission
 recording) imaging method rapidlyidentifies conformational differences in
 Aβ and tau deposits from Down syndrome,sporadic and familial Alzheimer’s
 disease human brain slices. EMBER has in situidentified distinct
 conformational strains of tau inclusions in astrocytes, oligoden-drocytes,
 and neurons from Pick’s disease. In future studies, EMBER should
 enablehigh-throughput measurements of the fidelity of strain transmission
 in cellular andanimal neurodegenerative diseases models, time course of
 amyloid strain propagation,and identification of pathogenic versus benign
 strains.

title: Data from: Separate and combined effects of boat noise and a live crab predator on mussel valve gape behaviour

description: Data abstract: Data on the valve gape of mussels and the behaviour of
 stimulus crabs during sound exposure trials. We provide the raw valve gape
 data, processed data, and scripts to process the raw data, make plots, and
 run the statistics. Paper abstract: Noisy human activities at sea are
 changing the acoustic environment, which has been shown to affect marine
 mammals and fishes. Invertebrates, such as bivalves, have so far received
 limited attention despite their important role in the marine ecosystem.
 Several studies have examined the impact of sound on anti-predator
 behaviour using simulated predators, but studies using live predators are
 scarce. In the current study, we examined the separate and combined
 effects of boat sound playback and predator cues from shore crabs
 (Carcinus maenas) on the behaviour of mussels (Mytilus spp.). We examined
 the behaviour of the mussels using a valve gape monitor and scored the
 behaviour from the crabs in one of two types of predator test conditions
 from video footage to control for effects from potential, sound-induced
 variation in crab behaviour. We found that mussels closed their valve gape
 during boat noise and with a crab in their tank, but also that the
 stimulus combination did not add up to an even smaller valve gape. The
 sound treatment did not affect the stimulus crabs, but the behaviour of
 the crabs did affect the valve gape of the mussels. Future research is
 needed to examine whether these results stand in situ and whether valve
 closure due to sound have fitness consequences for mussels. The effects on
 the well-being of individual mussels from anthropogenic noise may be
 relevant for population dynamics in the context of pressure from other
 stressors, their role as ecosystem engineers, and in the context of
 aquaculture.

title: Red drum genotypes and raw fecundity data

description: Understanding the processes that drive reproductive success in marine fish
 stocks is critical to effective fisheries management. These processes can
 be difficult to investigate, especially in age-structured populations,
 because they occur at transgenerational scales. Reproductive success is
 often attributed to a small portion of the adult population (&lt;
 0.01%) and thought to be driven primarily by random external factors,
 consistent with the concept of sweepstakes reproductive success (SRS). A
 competing concept, the reproductive resilience paradigm, posits that fish
 have evolved complex spawner-recruit systems to achieve lifetime
 reproductive success and maintain population stability within highly
 variable environments. Here, we examine these two concepts. First, we
 analyze the popular sport fish red drum (Sciaenops ocellatus), drawing on
 genetic and reproductive data to estimate a plausible range for the Ne/NA
 ratio of effective population size (Ne) to adult abundance (NA) and to
 infer variance in lifetime reproductive success (V*k). Then, we synthesize
 available data and infer  for two other fishes that have ratios
 reportedly &gt; 0.10, the southern bluefin tuna (Thunnus maccoyii,
 Scombridae) and the silver seabream (Chrysophrys auratus, Sparidae).
 Although commonly regarded as an SRS species, red drum did not meet the
 SRS criterion. Overdispersed values were inferred for all three species,
 with those for red drum and silver seabream being dependent upon
 population-closure assumptions. Results are presented within the
 conceptual framework of reproductive resilience, considering the roles of
 random extrinsic forces versus evolved traits to achieve lifetime
 reproductive success and population stability in high and variable
 mortality environments.

title: Microhabitat selection of the big-headed turtle Platysternon megacephalum in the Hainan Tropical Rainforest National Park, China

description: Understanding species habitat requirements is vital for ensuring the
 success of targeted conservation and habitat restoration measures. The
 big-headed turtle (Platysternon megacephalum) is a freshwater species
 which is distributed across Southeast Asia. Due to the human threats posed
 by illegal pet trade and overharvesting for food and medicinal purposes,
 the species has undergone rapid decline. Furthermore, limited research has
 been conducted on this species, particularly regarding habitat preferences
 on Hainan Island, China. Therefore, this study examined the
 microhabitat selection of P. megacephalum using cage and sample plot
 methods in the Diaoluo Mountain area of the Hainan Tropical Rainforest
 National Park. Our results indicated that big-headed turtles select stream
 microhabitats at higher altitudes, in proximity to rocky substrates,
 several caves, and high diversity of food sources. Microhabitat
 utilization did not differ significantly between adults and juveniles.
 This suggests that protecting microhabitats and main food sources is
 important for the conservation of P. megacephalum. Our findings provide a
 reference for the protection of this species in Jianfeng, Yingge Ridge,
 and other areas in the Hainan Tropical Rainforest National Park.
description: # Microhabitat selection of the big-headed turtle Platysternon
 megacephalum in the Hainan Tropical Rainforest National Park, China ##
 Description of the data file: A sample plot of 10 m length with water
 surface as width of the stream was established. A capture cage containing
 a turtle was considered to be at the center of the experimental plot, with
 5-m intervals up and down the stream as the plot length. A sample plot
 centered around a cage with no turtles present was used as a control plot.
 Ten ecological factors were recorded, including vegetation coverage, water
 surface width (m), water depth (cm), water surface velocity (m/s),
 substrate type (stone/sand/mud, covering &gt; 60% of the plot), exposed
 stone rate (piece/m2), number of caves, plant root system (clump), food
 diversity (number of species in the turtle cage), and distance from
 disturbance (&lt; 50 m, 50–100 m, &gt; 100 m). A cave was defined as a
 small cavity formed by two or more stones large enough to accommodate a
 big-headed turtle nestled on the riverbed or the gap at the bottom of a
 large rock. Plant roots are potential hiding places for the big-headed
 turtle and were recorded as the number of visible root clumps at the edge
 of the riverbank within the sample plot. The distance from disturbance was
 recorded as the distance from the cage to the nearest road in multiples of
 50 m.
