title: Data from: Male mate choice for large gravid spots in a livebearing fish

description: Male mate choice occurs in a wide range of species, and males can increase
 their reproductive success by distinguishing between females based on
 their fecundity (e.g. large body size) or their expected sperm competition
 risk (e.g. virgins). However, patterns of male mate choice could be
 mitigated by variation in female physiological receptivity, as males can
 benefit by directing their mating efforts towards females that are at a
 point in their reproductive cycle when fertilization probability is
 highest. Here, we perform three experiments to assess whether male mate
 choice is influenced by cues of female physiological receptivity,
 fecundity or sperm competition risk in the pygmy halfbeak (Dermogenys
 collettei), a small livebearing fish. Female halfbeaks possess a ‘gravid
 spot’- an orange abdominal marking that is caused by pigmentation of the
 females’ skin and variation in embryo development and pigmentation during
 pregnancy. We show that gravid spot size increases towards parturition and
 is largest right before giving birth, independent of abdominal width or
 body length. Males consistently chose females with large gravid spots over
 females with small gravid spots. In contrast, males did not prefer larger
 females over smaller females or virgin females over mated females. As
 female halfbeaks store sperm prior to fertilizations, we suggest that
 males use the size of the gravid spot as a cue to direct their mating
 efforts to those females where the chance of fertilization is highest.

title: Data from: New cranial fossils of the Jurassic turtle Neusticemys neuquina and phylogenetic relationships of the only thalassochelydian known from the Eastern Pacific

description: Neusticemys neuquina is a turtle from the Upper Jurassic of the Neuquén
 Basin, Patagonia, Argentina. Here we describe in detail a new skull, lower
 jaw, and a vertebra, utilizing both traditional anatomical description and
 computed tomography (CT). New diagnostic cranial characters of Ne.
 neuquina are: a round depression on the ventral surface of the
 basisphenoid, a relatively larger oval foramen nervi trigemini and reduced
 and steepened triturating surfaces on both the maxilla and dentary. The
 new morphological information presented in this study was included in a
 phylogenetic analysis, the primary result of which was recovery of Ne.
 neuquina within Thalassochelydia. Characters recognized as synapomorphies
 of this clade include (1) anterolateral recess of the anterior surface of
 the quadrate positioned lateral to the processus trochlearis oticum, (2)
 presence of a fossa on the supraoccipital-opisthotic-exoccipital contact
 area, (3) foramina anterius caroticus cerebralis located close together
 but independently perforating the basisphenoid, and (4) presence of the
 splenial in the mandible. Two contrasting dispersal scenarios may explain
 how this species of Thalassochelydia can be found outside of Europe. The
 presence of Ne. neuquina in the Neuquén Basin could be the consequence of
 an early dispersion event, for which we lack intermediate forms, or it may
 be the result of a later event once the clade was already established in
 Europe.

title: Fall 2024 plant monitoring survey -- shoot height and flowering status of plants in permanent plots at GCE sampling sites 1-10

description: A quadrat survey was conducted in October 2024 to measure the species and size distribution of plants at 10 GCE LTER sampling sites. The quadrats were established as permanent plots at GCE sampling sites in October 2000 by placing wooden (since replaced with pvc) stakes at random locations across two nominal zones at each site, designated based on marsh structure (creekbank and high marsh). New plots were added each year as necessary to replace those lost due to catastrophic wrack disturbance or creek bank erosion. The plots were visually surveyed and the species, shoot height, and flowering status was recorded individually for each shoot over 10 cm in height present in each plot. Observations from plots exhibiting signs of disturbance were noted in a separate data set (PLT-GCEM-1801). This survey will be repeated annually to assess changes in plant distribution and biomass in relation to environmental changes documented by other GCE LTER monitoring efforts.

title: Data from: Parental responses to increasing levels of handicapping in a burying beetle

description: Parental care is highly variable, reflecting that parents make flexible
 decisions about how much care to provide in response to variation in the
 cost and/or benefit of care. Handicapping has traditionally been used as a
 tool for increasing the energetic cost of care, thereby inducing a
 reduction in care by handicapped parents. However, recent evidence shows
 that handicapped parents sometimes provide more care, suggesting that
 handicapping can trigger terminal investment. Here, we investigate
 responses to different levels of handicapping in the burying beetle
 Nicrophorus vespilloides by comparing handicapped female parents fitted
 with a wide range of handicaps, as well as control females without a
 handicap. We found that handicapped females spent more time provisioning
 food and less time being absent from the crypt than control females,
 whilst there was no effect of the level of handicapping among handicapped
 females. We found no effect of handicapping on larval begging behavior,
 larval performance (mean larval mass and brood size at dispersal), or
 female investment in future reproduction (i.e., weight gain whilst
 breeding and life span after breeding). Our findings provide no support
 for the widely held assumption that handicapping simply increases the cost
 of care. Instead, our results are consistent with the suggestion that
 handicapping triggers terminal investment by suppressing the condition of
 parents below the threshold at which terminal investment is triggered.

title: Data from: Interacting maternal and spatial cues influence natal dispersal out of social groups

description: Proximate cues for animal dispersal are complex and varied. Multiple cues
 may provide information about different aspects of habitat quality, and
 these aspects may interact with each other, as well as with population
 density in different ways. We examined how individuals incorporate
 multiple cues in their decisions to emigrate and immigrate in the colonial
 orb-weaving spider, Cyrtophora citricola. We manipulated maternal feeding
 as a cue for prey abundance and measured the size of the maternal web,
 which provides a limited space for philopatric offspring and a second
 potential dispersal cue. In addition, we recorded all immigration events
 to determine dispersal distances and the cues juveniles may use in
 settlement. Dispersal increased when mothers were poorly fed, web sizes
 were small, and clutch sizes were large. In addition to these overall
 effects, maternal feeding also interacted with web size, indicating that
 offspring from well-fed mothers were more tolerant of high sibling
 densities. We also detected a threshold for the effect of clutch size on
 dispersal for the first egg sac: below 20 offspring, there was no effect
 of clutch size, but dispersal increased with clutch size for larger
 clutches. Dispersal distances were often short, and immigrants preferred
 sheltered trees and those occupied by adult females. Dispersal not only
 depended on multiple cues, but these cues interacted, and the importance
 of web size suggested that saturation of the natal web might force
 dispersal, at least for spiders with poorly-fed mothers. How one aspect of
 habitat quality influences dispersal can therefore depend on the state of
 other aspects of habitat quality. In particular, some natal resources,
 such as a nest or territory, may become saturated and limit group size,
 but this limit will also depend on other factors, such as prey
 availability.

title: Data from: Genetic diversity, population structure and migration scenarios of the marsupial “Monito del Monte” in south-central Chile.

description: In this study, we quantified the three pivotal genetic processes (i.e.,
 genetic diversity, spatial genetic structuring and migration) necessary
 for a better biological understanding and management of the singular
 “living-fossil” and near-threatened mouse opossum marsupial Dromiciops
 gliroides, the “Monito del Monte”, in south-central Chile. We used 11
 microsatellite loci to genotype 47 individuals distributed on the mainland
 and northern Chiloé Island. Allelic richness, observed and expected
 heterozygosity, inbreeding coefficient and levels of genetic
 differentiation were estimated. The genetic structure was assessed based
 on Bayesian clustering methods. In addition, potential migration scenarios
 were evaluated based on a coalescent theory framework and Bayesian
 approach to parameter estimations. Microsatellites revealed moderate to
 high levels of genetic diversity across sampled localities. Moreover, such
 molecular markers suggested that at least two consistent genetic clusters
 could be identified along the D. gliroides distribution (“Northern” and
 “Southern” cluster). However, general levels of genetic differentiation
 observed among localities and between the two genetic clusters were
 relatively low. Migration analyses showed that the most likely routes of
 migration of D. gliroides occurred a) from the Southern cluster to the
 Northern cluster and b) from the Mainland to Chiloé Island. Our results
 could represent critical information for future conservation programs and
 for a recent proposal about the taxonomic status of this unique mouse
 opossum marsupial.

title: Data from: Community structure of a Neotropical bat fauna as revealed by stable isotope analysis: Not all species fit neatly into predicted guilds

description: Neotropical bat communities are among the most diverse mammal communities
 in the world, and a better understanding of these assemblages may permit
 inferences about how so many species coexist. While broad trophic guilds
 (e.g., frugivore, insectivore) of bats are recognized, details of diet and
 similarities among species remain largely unknown. We used stable isotope
 ratios of carbon (δ13C) and nitrogen (δ15N) to characterize the community
 structure of a diverse Neotropical bat fauna from Belize to test
 predictions of niche theory and the competitive exclusion principle. We
 predicted that (1) interspecific variation in isotopic overlap would be
 greater within guilds than between guilds, and (2) no two sympatric
 populations would have isotopic niches that overlap completely, unless
 there is variation along some other axis (e.g., temporal, spatial). We
 additionally tested body size as an explanatory metric of potential
 overlap, and predicted that larger-bodied animals would have greater niche
 breadths. Results suggest that while guild-level characterizations of
 communities is at least somewhat informative, there are multiple examples
 of intra- and inter-guild species pairs with significantly overlapping
 isotopic niches, suggesting that, counter to predictions, they may compete
 for resources. Understanding the trophic structure of animal communities
 is fundamental to conservation and management of endangered species and
 ecosystems and important for evolutionary studies, and stable isotope
 analyses can provide key insights as well as informing hypotheses of the
 diet of species that are not well known.

title: Data from: An individual-based model of seed and rhizome propagated perennial plant species and sustainable management of Sorghum halepense in soybean production systems in Argentina

description: Perennial plants which propagate through both seeds and rhizomes are
 common in agricultural and non-agricultural systems. Due to their
 multifaceted life cycle, few population models are available for studying
 such species. We constructed a novel individual-based model to examine the
 effects of ecological, evolutionary and anthropogenic factors on the
 population dynamics of perennial species. To exemplify the application of
 the model, we presented a case study of an important weed, Sorghum
 halepense (L.) Pers. (Johnsongrass), in soybean productions in Argentina.
 The model encompasses a full perennial weed life cycle with both sexual
 (seeds) and asexual (rhizomes) propagations. The evolution of herbicide
 resistance was modelled based on either single genes or quantitative
 effects. Field experiments were conducted in the species’ native
 environment in Argentina to parameterise the model. Simulation results
 showed that resistance conferred by single-gene mutations was
 predominantly affected by the initial frequency of resistance alleles and
 the associated fitness cost. Population dynamics were influenced by
 evolved resistance, soil tillage, and rhizome fecundity. Despite the
 pivotal role of rhizomes in driving the population dynamics of
 Johnsongrass, most herbicides target the aboveground biomass, and chemical
 solutions to control rhizomes are still very limited. To maintain
 effective (short-term) and sustainable (long-term) weed management, it is
 recommended to combine soil tillage with herbicide applications for
 suppressing the rhizomes and delaying the evolution of resistance. This
 novel model of a seed- and rhizome-propagated plants will also be a useful
 tool for studying the evolutionary processes of other perennial weeds,
 cash crops and invasive species.

title: Data from: Earlier plant growth helps compensate for reduced carbon fixation after 13 years of warming

description: 1.Drylands play a dominant role in global carbon cycling and are
 particularly vulnerable to increasing temperatures, but our understanding
 of how dryland ecosystems will respond to climatic change remains notably
 poor. Considering that the area of drylands is projected to increase
 11–23% by 2100, understanding the impacts of warming on the functions and
 services furnished by these arid and semiarid ecosystems has numerous
 implications. 2.In a unique 13‐year ecosystem warming experiment in a
 southwestern U.S. dryland, we investigated the consequences of rising
 temperature on Achnatherum hymenoides, a widespread, keystone grass
 species on the Colorado Plateau. We tracked individual‐ and
 population‐level responses to identify optimal strategies that may have
 been masked if considering only one level of plant response. 3.We found
 several factors combined to affect the timing and magnitude of plant
 responses during the 13th year of warming. These included large
 warming‐induced biomass increases for individual plants, an 8.5‐day
 advancement in the growing season, and strong reductions in photosynthetic
 rates and population cover. 4.Importantly, we observed a lack of
 photosynthetic acclimation and, thus, a warming‐induced downregulation of
 photosynthetic rates. However, these physiological responses were
 concurrent with warmed‐plant increases in growing season length and
 investment in photosynthetic surfaces, demonstrating the species'
 ability to balance carbon fixation limitations with warming. 5.These
 results, which bring together ecophysiological, phenological,
 reproductive, and morphological assessments of plant responses to warming,
 suggest that the extent of change in A. hymenoides populations will be
 based upon numerous adaptive responses that vary in their direction and
 magnitude. Plant population responses to climatic warming remain poorly
 resolved, particularly for Earth's drylands, and our in situ
 experiment assessing multiple strategies offers a novel look into a warmer
 world.

title: Data from: Correlations between genetic, epigenetic and phenotypic variation of an introduced clonal herb

description: Heritable epigenetic modifications may occur in response to environmental
 variation, further altering phenotypes through gene regulation, without
 genome sequence changes. However, epigenetic variation in wild plant
 populations and their correlations with genetic and phenotypic variation
 remain largely unknown, especially for clonal plants. We investigated
 genetic, epigenetic and phenotypic variation of ten populations of an
 introduced clonal herb Hydrocotyle vulgaris in China. Populations of H.
 vulgaris exhibited extremely low genetic diversity with one genotype
 exclusively dominant, but significantly higher epigenetic diversity. Both
 intra- and inter-population epigenetic variation were related to genetic
 variation. But there was no correlation between intra- / inter-population
 genetic variation and phenotypic variation. When genetic variation was
 controlled, intra-population epigenetic diversity was related to petiole
 length, specific leaf area, and leaf area variation, while
 inter-population epigenetic distance was correlated with leaf area
 differentiation. Our study provides empirical evidence that even though
 epigenetic variation is partly under genetic control, it could also
 independently play a role in shaping plant phenotypes, possibly serving as
 a pathway to accelerate evolution of clonal plant populations.

title: Data from: Pulsed resource availability changes dietary niche breadth and partitioning between generalist rodent consumers

description: Identifying the mechanisms that structure niche breadth and overlap
 between species is important for determining how species interact and
 assessing their functional role in an ecosystem. Without manipulative
 experiments, assessing the role of foraging ecology and interspecific
 competition in structuring diet is challenging. Systems with regular
 pulses of resources act as a natural experiment to investigate the factors
 that influence the dietary niches of consumers. We used natural pulses of
 mast-fruiting of American beech (Fagus grandifolia) to test whether
 optimal foraging or competition structure the dietary niche breadth and
 overlap between two congener rodent species (Peromyscus leucopus and P.
 maniculatus), both of which are generalist consumers. We reconstructed
 diets seasonally over a two-year period using stable isotope analysis
 (δ13C, δ15N) of hair and of potential dietary items and measured niche
 dynamics using standard ellipse area calculated within a Bayesian
 framework. Changes in niche breadth were generally consistent with
 predictions of optimal foraging theory, with both species consuming more
 beech nuts (a high-quality food resource) and having a narrower niche
 breadth during masting seasons compared to non-masting seasons when
 dietary niches expanded and more fungi (a low quality food source) were
 consumed. In contrast, changes in dietary niche overlap were consistent
 with competition theory, with higher diet overlap during masting seasons
 than during non-masting seasons. Overall, dietary niche dynamics were
 closely tied to beech masting, underscoring that food availability
 influences competition. Diet plasticity and niche partitioning between the
 two Peromyscus species may reflect differences in foraging strategies,
 thereby reducing competition when food availability is low. Such dietary
 shifts may have important implications for changes in ecosystem function,
 including the dispersal of fungal spores.
