An increasing number of studies in a wide range natural systems have investigated how pulses resource availability influence ecological processes at individual, population, and community levels. Taken together, these suggest that some common may underlie pulsed dynamics diversity systems. Developing framework terms concepts for the study facilitate greater synthesis among apparently disparate Here, we propose general definition pulse concept, outline patterns causes consequences pulses, few...
Resource pulses are infrequent, large‐magnitude, and short‐duration events of increased resource availability. They include a diverse set extreme in wide range ecosystems, but identifying general patterns among the diversity pulsed phenomena nature remains an important challenge. Here we present meta‐analysis pulse–consumer interactions that addresses four key questions: (1) Which characteristics resources best predict their effects on consumers? (2) consumers responses to pulses? (3) How do...
Abstract Aim Ecological niche models are increasingly being used to aid in predicting the effects of future climate change on species distributions. Complex that show high predictive performance current distribution data may do a poor job new due overfitting. In addition, model is often evaluated using techniques sensitive spatial sampling bias. Here, we explore complexity and bias for 90 vertebrate taxa conservation concern. Location California, USA . Methods We Akaike information criterion...
The effect of resource subsidies on recipient food webs has received much recent attention. purpose this study was to measure the effects significant seasonal seaweed deposition events, caused by hurricanes and other storms, species inhabiting subtropical islands. represents a pulsed subsidy that is consumed amphipods flies, which are eaten lizards predatory arthropods, in turn consume terrestrial herbivores. Additionally, decomposes directly into soil under plants. We added six shoreline...
The trophic cascade has emerged as a key paradigm in ecology. Although ecologists have made progress understanding spatial variation the strength of cascades, temporal remains relatively unexplored. Our review suggests that strong cascades are often transient, appearing when ecological conditions support high consumer abundance and rapidly growing, highly edible prey. Persistent top-down control is expected to decay over time absence external drivers, favors emergence better-defended...
Abstract The study of gecko adhesion is necessarily interdisciplinary due to the hierarchical nature adhesive system and complexity interactions between animals their habitats. In nature, geckos move on a wide range surfaces including soft sand dunes, trees, rocks, but much research over past two decades has focused performance artificial surfaces. Exploring complex natural habitats will reveal aspects that can be applied biomimetic research, such as factors facilitate movement dirty rough...
Pulsed resource subsidies can have profound effects on recipient communities. The of pulses are often mediated by increases in the density consumer populations. Here we investigate several mechanisms linking experimental seaweed deposition to population‐level responses brown anole Anolis sagrei . Subsidized lizards grew approximately 30% faster than seaweed‐removal plots, but there was no effect survival or body condition. Breeding is strongly seasonal A. , resulting a limited reproductive...
Abstract Aim Ecological niche modelling is one of the main tools that allows for incorporation climate change effects into conservation planning. For example, ecological model predictions can be used to rank species by degree predicted future habitat loss. While many studies have considered how different decisions contribute uncertainty in outputs, here we evaluate metrics risk respond choice global models, greenhouse gas emission scenarios, suitable versus unsuitable threshold values, and...
Objective: This study investigated whether certain misperceptions of substance use disorders (SUDs) would influence stigmatizing attitudes toward individuals who have SUDs. Method: Using a between-subjects design, 1059 young adults (77.2% women) read vignettes describing characters with high or low levels the following factors: responsibility, controllability, immorality, willpower, consequences, and accountability. Participants then completed measures stigma each character (i.e., affective...
We quantified basking site usage by native western pond turtles (Emys [ = Actinemys] marmorata) and introduced red-eared sliders (Trachemys scripta elegans) in an urbanized waterway. A lower frequency of human disturbance, steeper slopes, shallower water adjacent to sites, a concrete substrate were all associated with higher abundance threatened relative sliders. These differences suggest new habitat management practices that could favor the face competition from invasive
The ranges and abundances of species that depend on freshwater habitats are declining worldwide. Efforts to counteract those trends often hampered by a lack information about distribution conservation status strongly biased toward few well-studied groups. We identified the 3,906 vascular plants, macroinvertebrates, vertebrates native California, USA, fresh water for at least one stage their life history. evaluated these taxa using existing government non-governmental organization assessments...
Baylisascarisprocyonis is a common parasitic nematode of the raccoonProcyonlotor. In intermediate or accidental hosts, including humans,B.procyonis can cause severe disease and mortality, parasite increasingly viewed as an important wildlife conservation public health concern. The prevalence B. procyonis was assessed over 4-year period in population raccoons forested region lower New York. Prevalence ranged from 0% (undetected) to 21%, which relatively low compared values reported other...
The gonad of the protogynous, hermaphroditic teleost, Monopterus albus were examined histologically at monthly intervals throughout one year. In particular, epithelium maturing follicles female and atretic in female, intersex male studied. Atretic common gonads classified as corpora atretica types 1 to 5 according histological criteria. addition, other regressive structures observed some males. histology frequency occurrence three sexual phases is described discussed.
Conservation scientists have adapted conservation planning principles designed for protection of habitats ranging from terrestrial to freshwater ecosystems. We applied current approaches in prioritize California watersheds management biodiversity. For all watersheds, we compiled data on the presence/absence herpetofauna and fishes; observations freshwater-dependent mammals, selected invertebrates, plants; maps habitat types; measures condition vulnerability; status. analyzed...

Abstract For arboreal lizards, the ability to cling or adhere substrate is critical for locomotion during prey capture, predator escape, thermoregulation and social interactions. Thus, selection on traits related clinging likely strong. Correlations between morphology, performance habitat use have been documented in providing a framework using functional predict field. We tested hypothesis that predicts an actively assembling community of introduced lizards Hawaiʻi comprised anoles ( Anolis...
Abstract Resource pulses are brief periods of unusually high resource abundance. While population and community responses to have been relatively well studied, how individual consumers respond has received less attention. Local often the first a pulse, form timing may influence effects pulse transmitted throughout community. Previous studies in Bahamian food webs shown that detritivores associated with seaweed wrack provide an alternative prey source for lizards. When is abundant, lizards (...
Abstract Introduced predators can have dramatic effects on island ecosystems, the magnitude of which are likely to vary with characteristics. We investigated influence two important properties islands—size and amount resource subsidy—on an introduced predatory lizard ( Anolis sagrei ) three groups arthropod prey. Lizards were experimentally 16 islands that spanned gradients in vegetated area seaweed deposition (a marine subsidy); similar served as lizard‐free controls. The abundance web...
Increases in consumer abundance following a resource pulse can be driven by diet shifts, aggregation, and reproductive responses, with combined responses expected to result faster response times larger numerical increases. Previous work plots on large Bahamian islands has shown that lizards (Anolis sagrei) increased pulses of seaweed deposition, which provide additional prey (i.e., detritivores). Numerical were associated rapid shifts followed reproduction. These dynamics are likely...
