title: Data from: Revising traditional theory on the link between plant body size and fitness under competition: evidence from old-field vegetation

description: The selection consequences of competition in plants have been
 traditionally interpreted based on a “size-advantage” hypothesis – that
 is, under intense crowding/competition from neighbors, natural selection
 generally favors capacity for a relatively large plant body size. However,
 this conflicts with abundant data, showing that resident species body size
 distributions are usually strongly right-skewed at virtually all scales
 within vegetation. Using surveys within sample plots and a
 neighbor-removal experiment, we tested: (1) whether resident species that
 have a larger maximum potential body size (MAX) generally have more
 successful local individual recruitment, and thus greater local
 abundance/density (as predicted by the traditional size-advantage
 hypothesis); and (2) whether there is a general between-species trade-off
 relationship between MAX and capacity to produce offspring when body size
 is severely suppressed by crowding/competition – that is, whether resident
 species with a larger MAX generally also need to reach a larger minimum
 reproductive threshold size (MIN) before they can reproduce at all. The
 results showed that MIN had a positive relationship with MAX across
 resident species, and local density – as well as local density of just
 reproductive individuals – was generally greater for species with smaller
 MIN (and hence smaller MAX). In addition, the cleared neighborhoods of
 larger target species (which had relatively large MIN) generally had – in
 the following growing season – a lower ratio of conspecific recruitment
 within these neighborhoods relative to recruitment of other (i.e.,
 smaller) species (which had generally smaller MIN). These data are
 consistent with an alternative hypothesis based on a
 ‘reproductive-economy-advantage’ – that is, superior fitness under
 competition in plants generally requires not larger potential body size,
 but rather superior capacity to recruit offspring that are in turn capable
 of producing grand-offspring – and hence transmitting genes to future
 generations – despite intense and persistent (cross-generational)
 crowding/competition from near neighbors. Selection for the latter is
 expected to favor relatively small minimum reproductive threshold size and
 hence – as a tradeoff – relatively small (not large) potential body size.

title: Data from: Effect of ecological momentary assessment, goal-setting and personalized phone-calls on adherence to interval walking training using the InterWalk application among patients with type 2 diabetes – a pilot randomized controlled trial

description: Objectives: The objective was to investigate the feasibility and usability
 of structured text-messages, goal-setting and phone-calls on adherence to
 a 12-week self-conducted interval walking training (IWT) program,
 delivered by the InterWalk smartphone among patients with type 2 diabetes
 (T2D). Methods: In a two-arm pilot randomized controlled trial (Denmark,
 March 2014 to February 2015), patients with T2D (18-80 years with a Body
 Mass Index of 18 and 40 kg/m2) were randomly allocated to 12 weeks of IWT
 with (intervention) or without additional support (control). The primary
 outcome was the difference between groups in accumulated time of interval
 walking training across 12 weeks. All patients were encouraged to use the
 InterWalk application to perform IWT for ≥90 minute/week. Patients in the
 intervention group made individual goals regarding lifestyle change,
 received automated text-messages once a week, inquiring about exercise
 adherence. In case of consistent non-adherence, the patients would receive
 a phone-call inquiring about the reason for non-adherence. The control
 group did not receive additional support. Information about training
 adherence was assessed objectively. Usability of structured text-messages
 was assessed based on response rates and self-reported satisfaction after
 12-weeks. Results: Thirty-seven patients with T2D (66 years, 65% female,
 hemoglobin 1Ac 50.3 mmol/mol) where included (n=18 and n=19 in
 intervention and control group, respectively). The retention rate was 83%.
 The intervention group accumulated [95%CI] 345 -7, 698 minutes of IWT
 more than the control group. The response rate for the text-messages was
 83% (68% for males and 90% for females). Forty-one percent of the
 intervention and 25% of the control group were very satisfied with their
 participation. Conclusion: The combination of structured text-messages,
 goal-setting with the possibility of follow-up phone calls are considered
 feasible interventions to attain training adherence when using the
 InterWalk app during a 12-week period in patients with T2D. Some
 uncertainty about the effect size of adherence remains.

title: Data from: Unpredictable perturbation reduces breeding propensity regardless of pre-laying reproductive readiness in a partial capital breeder

description: Theoretically, individuals of migratory species should optimize
 reproductive investment based on a combination of timing of and body
 condition at arrival on the breeding grounds. A minimum threshold body
 mass is required to initiate reproduction, and the timing of reaching this
 threshold is critical because of the trade-off between delaying breeding
 to gain in condition against the declining value of offspring with later
 reproductive timing. Long-lived species have the flexibility within their
 life history to skip reproduction in a given year if they are unable to
 achieve this theoretical mass threshold. Although the decision to breed or
 not is an important parameter influencing population dynamics, the
 mechanisms underlying this decision are poorly understood. Here, we
 mimicked an unpredictable environmental perturbation that induced a
 reduction in body mass of Arctic pre-breeding (before the laying period)
 female common eiders (Somateria mollissima; a long-lived migratory
 seaduck) while controlling for individual variation in the pre-laying
 physiological reproductive readiness via vitellogenin (VTG) - a
 yolk-targeted lipoprotein. Our aim was to causally determine the
 interaction between body condition and pre-laying reproductive readiness
 (VTG) on breeding propensity by experimentally reducing body mass in
 treatment females. We first demonstrated that arrival body condition was a
 key driver of breeding propensity. Secondly, we found treatment and VTG
 levels interacted to influence breeding propensity, indicating that our
 experimental manipulation, mimicking an unpredictable food shortage,
 reduced breeding propensity, regardless of the degree of pre-laying
 physiological reproductive readiness (i.e., timing of ovarian follicles
 recruitment). Our experiment demonstrates that momentary environmental
 perturbations during the pre-breeding period can strongly affect the
 decision to breed, a key parameter driving population dynamics.

title: Data from: The role of predation and food limitation on claims for compensation, reindeer demography and population dynamics

description: 1. A major challenge in biodiversity conservation is to facilitate viable
 populations of large apex predators in ecosystems where they were recently
 driven to ecological extinction due to resource conflict with humans. 2.
 Monetary compensation for losses of livestock due to predation is
 currently a key instrument to encourage human–carnivore coexistence.
 However, a lack of quantitative estimates of livestock losses due to
 predation leads to disagreement over the practise of compensation
 payments. This disagreement sustains the human–carnivore conflict. 3. The
 level of depredation on year-round, free-ranging, semi-domestic reindeer
 by large carnivores in Fennoscandia has been widely debated over several
 decades. In Norway, the reindeer herders claim that lynx and wolverine
 cause losses of tens of thousands of animals annually and cause negative
 population growth in herds. Conversely, previous research has suggested
 that monetary predator compensation can result in positive population
 growth in the husbandry, with cascading negative effects of high grazer
 densities on the biodiversity in tundra ecosystems. 4. We utilized a
 long-term, large-scale dataset to estimate the relative importance of lynx
 and wolverine predation and density-dependent and climatic food limitation
 on claims for losses, recruitment and population growth rates in Norwegian
 reindeer husbandry. 5. Claims of losses increased with increasing predator
 densities, but with no detectable effect on population growth rates.
 Density-dependent and climatic effects on claims of losses, recruitment
 and population growth rates, were much stronger than the effects of
 variation in lynx and wolverine densities. 6. Synthesis and applications.
 Our analysis provides a quantitative basis for predator compensation and
 estimation of the costs of reintroducing lynx and wolverine in areas with
 free-ranging semi-domestic reindeer. We outline a potential path for
 conflict management which involves adaptive monitoring programs, open
 access to data, herder involvement, and development of management strategy
 evaluation (MSE) models to disentangle complex responses including
 multiple stakeholders and individual harvester decisions.

title: Data from: Variation in offspring size with birth order in placental fish: a role for asymmetric sibling competition?

description: Asymmetric sibling competition arises when siblings with different
 competitive abilities share a limited resource. Such competition occurs in
 species with postnatal parental care and may also occur when mothers
 provision embryos between fertilization and birth (matrotrophy). We
 hypothesized that the combination of matrotrophy and the simultaneous
 provisioning of embryos in different stages of development (superfetation)
 leads to asymmetric competition between sibling embryos. Moreover, we
 expect the intensity of this competition to increase with the level of
 superfetation as high levels of superfetation result in greater temporal
 overlap between broods. This hypothesis predicts that offspring from early
 broods, which predominantly compete with less developed siblings, will be
 larger at birth than offspring from later broods, which experience
 competition from more and less developed siblings. Data on offspring size
 at birth from two populations of the highly matrotrophic fish, Heterandria
 formosa, and similar studies of poeciliid fish spanning a range of life
 histories are consistent with our hypothesis. Together these results
 suggest that sibling competition is a direct consequence of the evolution
 of matrotrophy and superfetation in poeciliid fish.

title: Data from: The behavioral type of a top predator drives the short-term dynamic of intraguild predation

description: Variation in behavior among individual top predators (i.e., the behavioral
 type) can strongly shape pest suppression in intraguild predation (IGP).
 However, the effect of a top predator’s behavioral type—namely, foraging
 aggressiveness (number of killed divided by prey time) and prey choosiness
 (preference degree for certain prey type)—on the dynamic of IGP may
 interact with the relative abundances of top predator, mesopredator, and
 pest. We investigated the influence of the top predator’s behavioral type
 on the dynamic of IGP in a three-species system with a top predator
 spider, a mesopredator spider, and a psyllid pest using a simulation
 model. The model parameters were estimated from laboratory experiments and
 field observations. The top predator’s behavioral type altered the
 food-web dynamics in a context-dependent manner. The system with an
 aggressive/nonchoosy top predator, without prey preferences between pest
 and mesopredator, suppressed the pest more when the top predator to
 mesopredator abundance ratio was high. In contrast, the system with a
 timid/choosy top predator that preferred the pest to the mesopredator was
 more effective when the ratio was low. Our results show that the
 behavioral types and abundances of interacting species need to be
 considered together when studying food-web dynamics, because they
 evidently interact. To improve biocontrol efficiency of predators,
 research on the alteration of their behavioral types is needed.

title: Data from: Sialendoscopy enhances salivary gland function in Sjögren’s syndrome: a 6 month follow-up, randomized and controlled, single blind study

description: Objectives: To assess the effect of sialendoscopy of the major salivary
 glands on salivary flow and xerostomia in patients with Sjögren’s syndrome
 (SS). Methods: Forty nine SS patients were randomly assigned to a control
 group (n=15) and two intervention groups: irrigation of the major glands
 with saline (n=16) or with saline followed by triamcinolone acetonide (TA)
 in saline (n=18). Unstimulated whole saliva flow (UWS), chewing stimulated
 whole saliva flow (SWS), citric-acid stimulated parotid flow (SPF),
 Clinical Oral Dryness Score (CODS), Xerostomia Inventory score (XI), and
 EULAR SS Patient Reported Index (ESSPRI) were obtained 1 week (T0) before,
 and 1(T1), 8(T8), 16(T16), and 24(T24) weeks after sialendoscopy. Results:
 Median baseline UWS, SWS and SPF scores were, respectively, 0.14, 0.46,
 and 0.22mL/min. After intervention, significant increases in UWS and SWS
 were observed in the saline group (at T8 (p=0.013) and T24 (p=0.004)) and
 the saline/TA group (at T24 (p=0.03) and T=16 (p=0.035). SPF was increased
 significantly in the saline/TA group at T24 (p=0.03). XI scores declined
 after sialendoscopy in both intervention groups. Compared to the control
 group, CODS, XI, and ESSPRI improved in the intervention groups. UWS, SWS,
 and SPF were higher in the intervention groups compared to the control
 group, but these differences were not significant except for SPF in the
 saline/TA group at T24 (p=0.005). Conclusions: Irrigation of the major
 salivary glands in SS patients enhances salivary flow and reduces
 xerostomia up to 6 months after sialendoscopy.

title: Data from: Nutrient release from moose bioturbation in aquatic ecosystems

description: While the ecological importance of bioturbation is well recognized and the
 prevalence of aquatic foraging by terrestrial ungulates is increasingly
 appreciated, research linking how terrestrial ungulates function as
 disturbance mechanisms via bioturbation in freshwater systems is lacking.
 The purpose of this study was to quantify potential nutrient pulses
 released from benthic sediments into the water column when moose Alces
 alces feed on aquatic plants. We also determined if we could
 experimentally mimic the benthic disturbance and the expected nutrient
 pulse created when moose feed aquatically. When moose foraged aquatically,
 significant releases of both total and dissolved phosphorus (P) and
 nitrogen (N) resulted in the waters that were disturbed in foraging areas
 compared to adjacent undisturbed waters. Nutrient concentrations for total
 P and N ranged from 42.5 × and 2.7 × greater in disturbed than
 undisturbed, respectively. Dissolved P and N were 26.8 × and 1.5 ×
 greater, respectively, in disturbed versus undisturbed waters. Our
 experimental mimic created increases of total and dissolved P and N that
 were equivalent to pulses created by moose. This indicates that it is
 possible to experimentally test by proxy the potential impact of moose
 bioturbation on other ecosystem processes. This study is the first
 quantification of moose foraging as a consumer mechanism that influences
 the release of limiting nutrients in aquatic systems, thereby emphasizing
 the potential cascading importance for nutrient uptake and productivity of
 plants and microbes.

title: Data from: Postcanine microstructure in Cricodon metabolus, a Middle Triassic gomphodont cynodont from south-eastern Africa

description: Cricodon metabolus is a trirachodontid cynodont from the Anisian (Middle
 Triassic) of eastern and southern Africa. It has labiolingually expanded
 (gomphodont) postcanines but also a sectorial tooth in the last postcanine
 locus. In this paper, we examine the crown microstructure of isolated
 sectorial and gomphodont postcanines belonging to the holotype specimen of
 this taxon using scanning electron microscopy. The enamel of both teeth is
 prismless and composed of discontinuous columnar divergence units,
 supporting the consistent presence of synapsid columnar enamel in
 cynognathians. Abundant tubules and numerous irregularly spaced
 incremental lines are also visible in the enamel and dentine layers in
 each tooth. This study reveals that the enamel thickness varies along the
 tooth row in Cricodon as the enamel layer of the gomphodont postcanines is
 11.5 times thicker than that of the sectorial crown. It is likely that
 this difference reflects occlusal stresses and fewer replacements in
 gomphodont postcanines relative to sectorial teeth. Approximately 100
 incremental growth lines of von Ebner are present in the dentine layer,
 indicating that the deposition of the dentine by odontoblasts occurred for
 three months before the animal's death.

title: Data from: The critical role of local refugia in postglacial colonization of Chinese pine: joint inferences from DNA analyses, pollen records, and species distribution modeling

description: The importance of long-distance migration from low to high latitudes
 relative to local spread from northern refugia after the Last Glacial
 Maximum (LGM) remains a focus of debate for many temperate tree species.
 We assessed the dynamics of Chinese pine (Pinus tabulaeformis), a
 widespread species endemic to northern China, since the LGM by integrating
 cytoplasmic DNA data, mapped pollen records and ecological niche modeling.
 Genetic variation among 544 individuals from 50 populations spanning the
 entire natural species range revealed eight genetic clusters with distinct
 geographic distribution, indicating glacial lineages likely originating
 from multiple local microrefugia. Palynological evidence suggested that
 the northernmost part of the natural distribution originated from local
 postglacial spread. Niche modeling indicated high probability of the
 species being present in the area of the Loess Plateau and coastal areas
 north of the Yangtze River during the LGM. The three lines of evidence
 jointly suggest that the species persisted through the last glaciation in
 the mountains surrounding the Loess Plateau of northern China and that the
 current distribution of the species originated primarily from the spread
 of local refugial populations, instead of long-distance migration. These
 results cast doubt on the notion that Chinese pine migrated from areas
 south of the Yangtze River and underscore the importance of northern
 refugia.

title: Data from: Adaptation costs to constant and alternating polluted environments

description: Some populations quickly adapt to strong and novel selection pressures
 caused by anthropogenic stressors. However, this short-term evolutionary
 response to novel and harsh environmental conditions may lead to
 adaptation costs, and evaluating these costs is important if we want to
 understand the evolution of resistance to anthropogenic stressors. In this
 experimental evolution study, we exposed Caenorhabditis elegans
 populations to uranium (U populations), salt (NaCl populations),
 alternating uranium/salt treatments (U/NaCl populations), and to a control
 environment (C populations), over 22 generations. In parallel, we ran
 common-garden and reciprocal-transplant experiments to assess the adaptive
 costs for populations that have evolved in the different environmental
 conditions. Our results showed rapid evolutionary changes in life history
 characteristics of populations exposed to the different pollution regimes.
 Furthermore, adaptive costs depended on the type of pollutant:
 pollution-adapted populations had lower fitness than C populations, when
 the populations were returned to their original environment. Fitness in
 uranium environments was lower for NaCl populations than for U
 populations. In contrast, fitness in salt environments was similar between
 U and NaCl populations. Moreover, fitness of U/NaCl populations showed
 similar or higher fitness in both the uranium and the salt environments
 compared to populations adapted to constant uranium or salt environments.
 Our results show that adaptive evolution to a particular stressor, can
 lead to either adaptive costs or benefits once in contact with another
 stressor. Furthermore, we did not find any evidence that adaptation to
 alternating stressors was associated with additional adaption costs. This
 study highlights the need to incorporate adaptive cost assessments when
 undertaking ecological risk assessments of pollutants.
