Deforestation and land use change are among the most pressing anthropogenic environmental impacts. In Brazil, a resurgence of malaria in recent decades paralleled rapid deforestation settlement Amazon basin, yet evidence deforestation-driven increase remains equivocal. We hypothesize an underlying cause this ambiguity is that influence each other bidirectional causal relationships-deforestation increases through ecological mechanisms reduces socioeconomic mechanisms-and strength these...
Abstract Predicting how increasing intensity of human–environment interactions affects pathogen transmission is essential to anticipate changing disease risks and identify appropriate mitigation strategies. Vector-borne diseases (VBDs) are highly responsive environmental changes, but such responses notoriously difficult isolate because depends on a suite ecological social in vectors hosts that may differ across species. Here we use the emerging tools cumulative pressure mapping machine...
Significance Here, we show how a conservation–health care exchange in rural Borneo preserved globally important forest carbon and simultaneously improved human health well-being, region of historically intense environmental destruction, widespread poverty, unmet needs. To evaluate this long-term conservation intervention, analyzed earth observation data, clinic records, socioeconomic surveys to quantify conservation, health, sustainable development outcomes simultaneously.

Abstract Lyme disease is the most common vector‐borne in temperate zones and a growing public health threat United States (US). The life cycles of tick vectors spirochete pathogen are highly sensitive to climate, but determining impact climate change on burden has been challenging due complex ecology presence multiple, interacting drivers transmission. Here we incorporated 18 years annual, county‐level case data panel statistical model investigate prior effects variation incidence while...
The distribution, abundance and seasonal activity of vector species, such as ticks mosquitoes, are key determinants vector-borne disease risk, strongly influenced by abiotic habitat conditions. Despite the numerous species tick vectors in heavily populated North American West Coast, all but Ixodes pacificus, primary Lyme spirochete, is poorly characterized with regard to patterns fine scale drivers distribution abundance, particularly regions southern California. This lack knowledge inhibits...
Tick-borne diseases, particularly Lyme disease, are emerging across the northern hemisphere. In order to manage diseases and predict where emergence will likely occur, it is necessary understand factors influencing distribution, abundance infection prevalence of vector species. North America, disease most common vector-borne transmitted by blacklegged ticks. This study aimed explore abiotic environmental drivers density western ticks (Ixodes pacificus) in southern California, an understudied...
Abstract Infectious diseases are rapidly emerging and many increasing in incidence across the globe. Processes of land‐use change, notably habitat loss fragmentation, have been widely implicated emergence spread zoonoses such as Lyme disease, yet evidence remains equivocal. Here, we discuss apply an innovative approach from social sciences; instrumental variables, which seeks to tease out causality observational data. Using this approach, revisit effect forest fragmentation on disease...
Abstract Global environmental change is having profound effects on the ecology of infectious disease systems, which are widely anticipated to become more pronounced under future climate and land use change. Arthropod vectors particularly sensitive changes in abiotic conditions such as temperature moisture availability. Recent research has focused shifting suitability for, geographic distribution of, vector species projected scenarios. However, shifts seasonal activity patterns, or phenology,...
Abstract Changing climate has driven shifts in species phenology, influencing a range of ecological interactions from plant–pollinator to consumer–resource. Phenological changes host–parasite systems have implications for pathogen transmission dynamics. The seasonal timing, or peak larval and nymphal tick abundance is an important driver tick‐borne prevalence through its effect on cohort‐to‐cohort transmission. Tick phenology tightly linked climatic factors such as temperature humidity....
ABSTRACT Quantifying ecosystem services provided by mobile species like insectivorous bats remains a challenge, particularly in understanding where and how these vary over space time. Bats are known to offer valuable services, such as mitigating insect pest damage crops, reducing pesticide use, nuisance populations. However, determining forage is difficult monitor. In this study, we use weather‐radar‐based bat‐monitoring algorithm estimate bat foraging distributions during the peak season of...
Mosquito-borne diseases are deeply embedded within ecological communities, with environmental changes - particularly climate change shaping their dynamics. Increasingly intesense droughts across the globe have profound implications for transmission of these diseases, as drought conditions can alter mosquito breeding habitats, host-seeking behaviors, and mosquito-host contact rates. To quantify effect on disease transmission, we use West Nile virus (WNV) a model system leverage robust dataset...
Abstract Early growth and environmental conditions can shape life-history trajectories. Long-lived iteroparous species with indeterminate face growth-reproduction trade-offs for most of their lives. Poor early delay primiparity restrict growth, potentially compensated by faster later in life, at the cost reduced reproduction. We explored variation age reproduction eastern grey kangaroos, based upon 13 years monitoring about 100 known-age females. then examined associations between...
Abstract Background Ectothermic arthropods, like ticks, are sensitive indicators of environmental changes, and their seasonality plays a critical role in the dynamics tick-borne disease warming world. Juvenile tick phenology, which influences pathogen transmission, may vary across climates, with longer seasons cooler climates potentially amplifying transmission. However, assessing juvenile phenology is challenging arid because ticks spend less time seeking for blood meals (i.e. questing) due...

The expansion of human settlement into wildland areas, including forests in the eastern United States, has resulted fragmented forest habitat that been shown to drive higher entomological risk for Lyme disease. We investigated an alternative pathway between fragmentation and disease, namely whether increased disease results a reduced propensity settle high-risk areas at interface developed undeveloped lands. used longitudinal data analyses county level determine incidence (LDI) influences...
Abstract Whether an ecological community is controlled from above or below remains a popular framework that continues generating interesting research questions and takes on especially important meaning in agroecosystems. We describe the regulation of three coffee herbivores, leaf herbivore (the green scale, Coccus viridis), seed predator berry borer, Hypothenemus hampei), plant pathogen rust disease, caused by Hemelia vastatrix) various natural enemies, emphasizing remarkable complexity...
Abstract Identifying the effects of human‐driven perturbations, such as species introductions or habitat fragmentation, on ecology and dynamics infectious disease has become a central focus ecologists. Yet, comparatively little is known about how zoonotic systems responds to catastrophic disturbance events wildfires hurricanes. In California, wildfire centrally important forests oak woodlands projected increase in severity extent under future climate change. Here, taking advantage recent...
Experiments and models suggest that climate affects mosquito-borne disease transmission. However, transmission involves complex nonlinear interactions between population dynamics, which makes detecting drivers at the level challenging. By analysing incidence data, estimated susceptible size, data with methods based on time series analysis (collectively referred to as empirical dynamic modelling), we identified their interactive effects dengue dynamics in San Juan, Puerto Rico.
