Objective. Depression in parents is a prevalent and impairing illness that encountered frequently medical practice. Children of depressed are at risk for psychopathology other difficulties. A series recent national reports have recommended the development prevention efforts targeting children parents. Yet, to date, few controlled studies depression adolescents been conducted. In this study, we report evaluation 2 preventive intervention strategies target living homes with Both public health...
This paper introduces the theory and application of discrete choice models to resource selection studies. Discrete calculate probability an individual selecting a as function attributes that all other available resources. The data for these may be continuous or categorical. When availability is same individuals only two resources are available, multinomial logit model reduces logistic model. advances in GIS technology give researcher flexibility defining separately each over time space....
Existing optimality models of propagule size and number are not appropriate for many organisms. First, existing assume a monotonically increasing offspring fitness/propagule relationship. However, survival during certain stages may decrease with size, generating peaked function (e.g., egg in oxygen‐limited aquatic environments). Second, typically do consider maternal effects on total reproductive output the expression survival/propagule relationships. larger females often have greater...
Although numerous studies have examined the individual effects of increased temperatures and N deposition on soil biogeochemical cycling, few considered how these disturbances interact to impact C dynamics. Likewise, many not assessed season-specific responses warming inputs despite seasonal variability in processes. We studied interactions among season, warming, additions respiration mineralization at Soil Warming × Nitrogen Addition Study Harvard Forest. Of particular interest were...
Summary Somatic growth is a fundamental property of living organisms, and particular importance for species with indeterminate that can change in size continuously throughout their life. For example, fishes increase by 2–6 orders magnitude during lifetime, resulting changes production, consumption function at the ecosystem scale. Within species, rates are traded off against other life‐history parameters, hence an accurate description essential to understand comparative demography,...
Species invasions have a range of negative effects on recipient ecosystems, and many occur at scale magnitude that preclude complete eradication. When extirpation is unlikely with available management resources, an effective strategy may be to suppress invasive populations below levels predicted cause undesirable ecological change. We illustrated this approach by developing testing targets for the control Indo-Pacific lionfish (Pterois volitans P. miles) Western Atlantic coral reefs. first...
Tunas and their relatives dominate the world's largest ecosystems sustain some of most valuable fisheries. The impacts fishing on these species have been debated intensively over past decade, giving rise to divergent views scale extent fisheries pelagic ecosystems. We use all available age-structured stock assessments evaluate adult biomass trajectories exploitation status 26 populations tunas (17 tunas, 5 mackerels, 4 Spanish mackerels) from 1954 2006. Overall, declined, average, by 60%...
Significance Black swans—statistically improbable events with profound consequences—happen more often than expected in financial, social, and natural systems. Our work demonstrates the rare but systematic presence of black-swan animal populations around world (mostly birds, mammals, insects). These are predominantly downward, implying that unexpected population crashes occur frequently increases. Black-swan not driven by life history (e.g., lifespan) external causes such as extreme winters...
Abstract The oceans face a biodiversity crisis, but the degree and scale of extinction risk remains poorly characterized. Charismatic species are most likely to garner greatest support for conservation thus provide best‐case scenario status marine biodiversity. We summarize diagnose impediments successful 1,568 in 16 families animals movie Finding Nemo . Sixteen percent (12–34%) those that have been evaluated threatened, ranging from 9% (7–28%) bony fishes 100% (83–100%) turtles. A lack...
Abstract The exploitation status of marine fisheries stocks worldwide is critical importance for food security, ecosystem conservation, and fishery sustainability. Applying a suite data‐limited methods to global catch data, combined through an ensemble modeling approach, we provide quantitative estimates 785 fish stocks. Fifty‐three percent (414 stocks) are below B MSY these, 265 estimated be 80% the level. While 149 above conventionally considered “fully exploited,” staying at this level...
Geographic variability in abundance can be driven by multiple physical and biological factors operating at scales. To understand the determinants of larval trematode prevalence within populations marine snail host Littorina littorea, we quantified many variables 28 New England intertidal sites. A hierarchical, mixed-effects model identified gulls (the final hosts dispersive agents infective stages) size (a proxy for time exposure) as primary associated with prevalence. The predominant...
The productivity and biomass of pristine coral reef ecosystems is poorly understood, particularly in the Caribbean where communities have been impacted by overfishing multiple other stressors over centuries. Using historical data on spatial distribution abundance extinct monk seal ( Monachus tropicalis ), this study reconstructs population size, structure ecological role once common predator within communities, provides evidence that reefs supported biomasses fishes invertebrates up to six...
Summary A financial portfolio metaphor is often used to describe how population diversity can increase temporal stability of a group populations. The effect (PE) refers the stabilizing from acting as or ‘portfolio’ diverse subpopulations instead single homogeneous ‘asset’. widely measure PE (the average‐CV PE) implicitly assumes that slope ( z ) log–log plot mean abundance and variance (Taylor's power law) equals two. Existing theory suggests an additional unexplored empirical accounts for ,...
Abstract Fishery managers must often reconcile conflicting estimates of population status and trend. Superensemble models, commonly used in climate weather forecasting, may provide an effective solution. This approach uses predictions from multiple models as covariates additional “superensemble” model fitted to known data. We evaluated the potential for ensemble averages superensemble (ensemble methods) improve trend fisheries. fit four widely applicable data‐limited that estimate stock...
The growing field of historical ecology describes population abundances, biodiversity, spatial structure, and ecological functioning in the past, which are important to understanding dynamics recovery potential. However, because analyses often incorporate nontraditional data sources (i.e., archival materials oral histories) may reveal unexpected changes species populations, results subject critiques objectivity quality control, hamper their broad application. Here, we argue that surprising...
Climate change is likely to lead increasing population variability and extinction risk. Theoretically, greater diversity should buffer against rising climate variability, this theory often invoked as a reason for conservation. However, has rarely been quantified. Here we show how portfolio approach managing can inform metapopulation conservation priorities in changing world. We develop salmon model which productivity driven by spatially distributed thermal tolerance patterns of short-...
Abstract Human-wildlife conflicts impose considerable costs to people and wildlife worldwide. Most research focuses on proximate causes, offering limited generalizable understanding of ultimate drivers. We tested three competing hypotheses (problem individuals, regional population saturation, food supply) that relate underlying processes human-grizzly bear ( Ursus arctos horribilis) conflict, using data from British Columbia, Canada, between 1960–2014. found most support for the supply...
Abundance trends are the basis for many classifications of threat and recovery status, but they can be a challenge to interpret because observation error, stochastic variation in abundance (process noise) temporal autocorrelation that process noise. To measure frequency incorrectly detecting decline (false-positive or false alarm) failing detect true (false-negative), we simulated stable declining time series across several magnitudes error autocorrelated We then empirically estimated...
