title: Experimental vacancies do not induce settlement despite habitat saturation in a cooperative breeder

description: The paradox of cooperative breeding ­whereby individuals assist others
 instead of reproducing independently­ is generally explained through
 ecological constraints, but experimental evidence is scant. Here we
 performed the crucial test of the role of habitat saturation through
 experimental creation of vacancies and find that despite abundant presence
 of potential mates, subordinates are reluctant to disperse into suitable
 vacant habitat where conspecifics are absent. We argue that sudden
 disappearance of multiple group members might indicate a heightened risk
 of predation. Thereby the results of this study are consistent with the
 ‘perceptual trap’ hypothesis: the avoidance of habitats because cues do
 not accurately reflect their quality. Interestingly, this hypothesis can
 also explain previous findings, which were widely interpreted as evidence
 for ecological constraints as a driver of cooperative breeding. Our
 results can have considerable implications for conservation as it means
 that opportunities for colonization might go unexploited.
description: We experimentally created vacancies using permanent
 translocations (&gt;10km away) with two different treatments. First,
 to test whether the limited availability of suitable habitat itself can
 promote delayed dispersal, seven pair vacancies were created by removing
 all group members from their territory before the onset the breeding
 season. In our second treatment, single sex vacancies (N=4 male, N=3
 female vacancies) were created by relocating either males or females from
 a territory, to confirm that dispersal can be experimentally
 initiated.

title: Experimentally increased brood size accelerates actuarial senescence and increases subsequent reproductive effort in a wild bird population

description: 1. The assumption that reproductive effort decreases somatic state,
 accelerating ageing, is central to our understanding of life-history
 variation. Maximal reproductive effort early in life is predicted to be
 maladaptive by accelerating ageing disproportionally, decreasing fitness.
 2. Optimality theory predicts that reproductive effort is restrained early
 in life to balance the fitness contribution of reproduction against the
 survival cost induced by the reproductive effort. When adaptive, the level
 of reproductive restraint is predicted to be inversely linked to the
 remaining life-expectancy, potentially resulting in a terminal effort in
 the last period of reproduction. 3. Experimental tests of the reproductive
 restraint hypothesis require manipulation of somatic state and subsequent
 investigation of reproductive effort and residual lifespan. To our
 knowledge the available evidence remains inconclusive, and hence
 reproductive restraint remains to be demonstrated. 4. We modulated somatic
 state through a lifelong brood size manipulation in wild jackdaws and
 measured its consequences for age-dependent mortality and reproductive
 success. 5. The assumption that lifelong increased brood size reduced
 somatic state was supported: Birds rearing enlarged broods showed
 subsequent increased rate of actuarial senescence, resulting in reduced
 residual lifespan. 6. The treatment induced a reproductive response in
 later seasons: Egg volume and nestling survival were higher in subsequent
 seasons in the increased vs. reduced broods’ treatment group. We detected
 these increases in egg volume and nestling survival despite the
 expectation that in the absence of a change in reproductive effort, the
 reduced somatic state indicated by the increased mortality rate would
 result in lower reproductive output. This leads us to conclude that the
 higher reproductive success we observed was the result of higher
 reproductive effort. 7. Our findings show that reproductive effort
 negatively co-varies with remaining life-expectancy, supporting optimality
 theory and confirming reproductive restraint as a key factor underpinning
 life-history variation. 24-Jan-2020

title: Neighboring trees regulate the root-associated pathogenic fungi on the host plant in a subtropical forest

description: Root-associated fungi and host-specific pathogens are major determinants
 of species coexistence in forests. Phylogenetically related neighboring
 trees can strongly affect the fungal community structure of the host
 plant, which, in turn, will affect the ecological processes.
 Unfortunately, our understanding of the factors influencing fungal
 community composition in forests is still limited. In particular,
 investigation of the relationship between the phytopathogenic fungal
 community and neighboring trees is incomplete. In the current study, we
 tested the host specificity of members of the root-associated fungal
 community collected from seven tree species and determined the influence
 of neighboring trees and habitat variation on the composition of the
 phytopathogenic fungal community of the focal plant in a subtropical
 evergreen forest. Using high-throughput sequencing data with respect to
 the internal transcribed spacer (ITS) region, we characterized the
 community composition of the root-associated fungi and found significant
 differences with respect to fungal groups among the seven tree species.
 The density of conspecific neighboring trees had a significantly positive
 influence on the relative abundance of phytopathogens, especially
 host-specific pathogens, while the heterospecific neighbor density had a
 significant negative impact on the species richness of host-specific
 pathogens, as well as phytopathogens. Our work provides evidence that the
 root-associated phytopathogenic fungi of a host plant depends greatly on
 the tree neighbors of the host plant.

title: Human-dominated landcover corresponds to spatial variation in Mourning Dove reproductive output across the United States.

description: Studies examining impacts of land cover typically focus on abundance,
 distribution, and/or community richness, overlooking underlying
 demographic processes such as survival or reproduction. Here, we present
 findings from a unique dataset that allowed us to measure the relationship
 between land cover and reproductive output across the distribution of the
 Mourning Dove (Macroura zenaida). We used hunter-derived, Mourning Dove
 wing data across 1,271 counties in the United States from 2008 to 2014 to
 estimate spatially explicit age ratios (juveniles: adults), an index of
 local reproductive output. We also used raster imagery data to estimate
 relationships between reproductive output and land cover and crop cover.
 We found that low reproductive output occurs in regions where Mourning
 Dove declines have been steepest. Our findings reveal that impacts of land
 cover vary geographically, but even at a coarse resolution, small changes
 in the relative proportion of human-dominated landscapes can have a
 significant impact on the reproductive output of this generalist species.
 Maize and soybean systems correlate with up to a 57% reduction in Mourning
 Dove reproductive output in the eastern United States. In the western
 United States, developed areas correlate with a 41% increase in
 reproductive output. Across the United States, native habitats had neutral
 or negative relationships with age ratios. Our study contributes
 continental-scale evidence that Mourning Dove reproductive output is
 largely driven by human-dominated land cover including agricultural and
 residential areas. With Mourning Doves declining across the range,
 discerning more fine-scale land cover factors is critical for ensuring
 Mourning Dove populations persist into the future.
description: Mourning Dove wing data was collected by the United States Fish
 and Wildlife Service Parts Program. Land cover and crop cover data were
 derived from the United States Department of Agriculture National Cropland
 Data Layer. The data has been processed to change the number of raster
 cells in a given U.S. county to a proportion of land cover in that
 county.

title: Research criteria for the diagnosis of prodromal dementia with Lewy bodies.

description: The prodromal phase of dementia with Lewy bodies (DLB) includes (i) mild
 cognitive impairment (MCI), (ii) delirium, and (iii) psychiatric-onset
 presentations. The purpose of our review is to determine whether there is
 sufficient information yet available to justify development of diagnostic
 criteria for each of these. Our goal is to achieve evidence-based
 recommendations for the recognition of DLB at a pre-dementia, symptomatic
 stage. We propose operationalized diagnostic criteria for probable and
 possible mild cognitive impairment with LB (MCI-LB), which are intended
 for use in research settings pending validation for use in clinical
 practice. They are compatible with current criteria for other prodromal
 neurodegenerative disorders including Alzheimer’s and Parkinson’s disease.
 While there is still insufficient evidence to propose formal criteria for
 delirium-onset, and psychiatric-onset presentations of DLB, we feel it
 important to characterise them, raising the index of diagnostic suspicion
 and prioritising them for further investigation.

title: Pollen color morphs take different paths to fitness

description: Color phenotypes are often involved in communication and are thus under
 selection by species interactions. However, selection may also act on
 color through correlated traits or alternative functions of biochemical
 pigments. Such forms of selection are instrumental in maintaining petal
 color diversity in plants. Pollen color also varies markedly, but the
 maintenance of this variation is little understood. In Campanula
 americana, pollen ranges from white to dark purple, with darker morphs
 garnering more pollinator visits and exhibiting elevated pollen
 performance under heat stress. Here, we generate an F2 population
 segregating for pollen color and measure correlations with floral traits,
 pollen attributes, and plant-level traits related to fitness. We determine
 the pigment biochemistry of color variants, and evaluate maternal and
 paternal fitness of light and dark morphs by crossing within and between
 morphs. Pollen color was largely uncorrelated with floral traits (petal
 color, size, nectar traits) suggesting it can evolve independently. Darker
 pollen grains were larger and had higher anthocyanin content (cyanidin and
 peonidin) which may explain why they outperform light pollen under heat
 stress. Overall, pollen-related fitness metrics were greater for dark
 pollen, and dark pollen sires generated seeds with higher germination
 potential. Conversely, light pollen plants produce 61% more flowers than
 dark, and 18% more seeds per fruit, suggesting a seed production
 advantage. Results indicate that light and dark morphs may achieve fitness
 through different means—dark morphs appear to have a pollen advantage
 while light morphs have an ovule advantage—helping to explain the
 maintenance of pollen color variation.

title: Long-term shifts in the functional composition and diversity of a tropical dry forest: a 30-yr study

description: Over the past three decades there has been a concerted effort to study the
 long-term dynamics of tropical forests throughout the world. Data
 regarding temporal trends in species diversity, species composition and
 species-specific demographic rates have now been amassed. Such data can be
 utilized to test predictions regarding the roles the environment and
 demographic stochasticity play in driving forest dynamics. These analyses
 could be further refined by quantifying the temporal trends in the
 functional compostion and diversity in tropical forests. For example, we
 have only a handful of studies that quantify directional shifts in the
 functional composition in tropical forests in response to global change
 drivers. The present study uses data from three censuses spanning 30 years
 in a Neotropical dry forest dynamics plot to provide novel insights into
 how the functional diversity and composition of a tropical forest has
 changed through time.  Specifically, here we aim to: (i)
 quantify population dynamics and compare it to that expected from
 environmental or demographic variance; (ii) to quantify long-term trends
 in species richness and functional diversity; (iii) test whether there
 have been directional changes in the functional composition of the forest
 though time and the population changes that are responsible for these
 changes; and (iv) place these long-term results into the context of the
 successional and climatic history of the forest.

title: Data from: On the scaling of activity in tropical forest mammals

description: Activity range – the amount of time spent active per day – is a
 fundamental aspect contributing to the optimization process by
 which animals achieve energetic balance. Based on their size and
 the nature of their diet, theoretical expectations are that
 larger carnivores need more time active to fulfil their energetic
 needs than do smaller ones and also more time active than
 similar-sized non-carnivores. Despite the relationship between
 daily activity, individual range and energy acquisition, large-scale
 relationships between activity range and body mass among wild
 mammals have never been properly addressed. This study aimed to
 understand the scaling of activity range with body mass, while
 controlling for phylogeny and diet. We built simple empirical
 predictions for the scaling of activity range with body mass for
 mammals of different trophic guilds and used
 a phylogenetically controlled mixed model to test these
 predictions using activity records of 249 mammal populations (128
 species) in 19 tropical forests (in 15 countries) obtained using
 camera traps. Our scaling model predicted a steeper scaling of
 activity range in carnivores (0.21) with higher levels of
 activity (higher intercept), and near-zero scaling in herbivores
 (0.04). Empirical data showed that activity ranges scaled positively
 with body mass for carnivores (0.061), which also had higher
 intercept value, but not for herbivores, omnivores and
 insectivores, in general, corresponding with the
 predictions. Despite the many factors that shape animal activity
 at local scales, we found a general pattern showing that large
 carnivores need more time active in a day to meet their energetic
 demands.
description: Camera-trap dataset We obtained empirical
 data on activity range from cameratrapping surveys in 19 tropical forests,
 distributed over four continents. Seventeen sites were part of the
 Tropical Ecology Assessment and Monitoring Network, and two additional
 sites were located in South America. All sites were surveyed by 50
 nonbaited cameras, spaced 2 km from each other. The camera grid was set
 for 30 consecutive days, during dry seasons, totalizing 1500 camera-days,
 according to the standardized TEAM protocol. We trimmed the photographic
 captures (henceforth ‘records’) in each database to meet the minimum of
 1-h interval between consecutive records of the same species at the same
 camera site to reduce temporal dependence. At each site, we only used
 species that had a minimum of 30 independent records, and excluded
 <em>Homo sapiens</em> and domesticated animals (as all
 surveyed sites were inside protected areas, the influence of people and
 domestic animals on the wildlife activity can be considered negligible).
 We defined the minimum of 30 records per species after performing analysis
 of sampling sufficiency through bootstrapping in order to estimate
 activity ranges.

title: Competition for resources can promote the divergence of social learning phenotypes

description: Social learning occurs when animals acquire knowledge or skills by
 observing or interacting with others, and is the fundamental building
 block of culture. Within populations, some individuals use social learning
 more frequently than others, but why social learning phenotypes differ
 among individuals is poorly understood. We modelled the evolution of
 social learning frequency in a system where foragers compete for resources
 and there are many different foraging options to learn about. Social
 learning phenotypes diverged when some options offered much better rewards
 than others and expected rewards changed moderately quickly over time.
 When options offered similar rewards or when rewards changed slowly, a
 single social learning phenotype evolved. This held for fixed and simple
 conditional social learning rules. Sufficiently complex conditional social
 learning rules prevented the divergence of social learning phenotypes
 under all conditions. Our results explain how competition can promote the
 divergence of social learning phenotypes.

title: Novel plant-microbe interactions: rapid evolution of a legume-rhizobium mutualism in restored prairies

description: 1. When plants colonize new habitats, the novel interactions they form
 with new mutualists or enemies can immediately affect plant performance.
 These novel interactions also may provoke rapid evolutionary responses and
 can be ideal scenarios for investigating how species interactions
 influence plant evolution. 2. To explore how mutualists influence the
 evolution of colonizing plant populations, we capitalized on an experiment
 in which two former agricultural fields were seeded with identical prairie
 seed mixes in 2010. Six years later, we compared how populations of the
 legume Chamaecrista fasciculata from these sites and their original
 (shared) source population responded to nitrogen-fixing rhizobia from the
 restoration sites in a greenhouse reciprocal cross-inoculation experiment.
 3. We found that the two populations differed both from their original
 source population and from each other in the benefits they derive from
 rhizobia, that one population has evolved reduced allocation to rhizobia
 (i.e., forms fewer rhizobium-housing nodules). 4. Synthesis. Our results
 suggest that these plant populations have evolved different ways of
 interacting with rhizobia, potentially in response to differences in
 rhizobium quality between sites. Our study illustrates how microbial
 mutualists may shape plant evolution in new environments and highlights
 how variation in microbial mutualists potentially may select for different
 evolutionary strategies in plant hosts.

title: Tributary confluences are dynamic thermal refuges for a juvenile salmonid in a warming river network

description: As rivers warm, cold-water fish species may alleviate thermal stress by
 moving into localized thermal refuges such as cold-water plumes created by
 cool tributary inflows. We quantified use of two tributary confluence
 plumes by juvenile steelhead, Oncorhynchus mykiss, throughout the summer,
 including how trout positioned themselves in relation to temperature
 within confluence plumes. At two confluences, Cedar and Elder creeks,
 along the South Fork Eel River, California, USA, we monitored temperatures
 using in-situ logger grids throughout summer 2016. Fish were counted
 within confluences via snorkel surveys five times a day on five days at
 each site. We found diel and seasonal dependence on confluence use by
 steelhead, especially at the Cedar Creek confluence, where mainstem
 temperatures exceeded 28°C. At this site, fish moved into the confluence
 on the warmest days and warmest times of the day. Fish observed within the
 Cedar Creek confluence plume were most common in locations between
 20-22°C, rather than the coldest locations (14.5˚C). At Elder Creek, where
 mainstem temperatures remained below 24˚C, there was little relationship
 between mainstem temperature and steelhead presence in the confluence
 plume. At both sites, steelhead distribution within plumes was influenced
 by spatial variation of temperature and mean temperature in surveyed grid
 cells. Our results show that cool tributaries flowing into warmer
 mainstems reaches (over 24˚C) likely create important thermal refuges for
 juvenile steelhead. As mainstem rivers warm with climate change,
 cool-water tributary inputs may become more important for sustaining
 cold-water salmonids near the southern end of their range.
