Multi‐species occupancy modeling provides novel insights into amphibian metacommunity structure and wetland restoration

چکیده

A fundamental goal of community ecology is to understand species–habitat relationships and how they shape metacommunity structure. Recent advances in occupancy modeling enable habitat be assessed for both common rare species within metacommunities using multi-species models (MSOM). These account imperfect detection offer considerable advantages over other analytical tools commonly used analyses under the elements structure (EMS) framework. Here, we demonstrate that MSOM can infer test theory, amphibians. Repeated frog surveys were undertaken at 55 wetland sites southeastern Australia. We detected 11 from three families (Limnodynastidae, Myobatrachidae, Pelodryadidae). The rarest was only one site whereas most 42 (naive rate 0.02–0.76). Two representing two competing hypotheses; best-supported model included covariates distance nearest (connectivity), area, presence non-native eastern mosquitofish (Gambusia holbrooki), proportion cover emergent vegetation, an interaction term between Gambusia vegetation cover, canopy a site. Hydroperiod played no detectable role found fit with current theory: increased area connectivity. There strong negative relationship predatory Gambusia, positive vegetation. strongly several tree species, highlighting importance terrestrial amphibian demonstrated responses by amphibians environmental level linked patterns scale. Our results have clear management implications: restoration projects likely taxa should maximize connectivity, establish partial eradicate or provide aquatic mitigate impact this fish. advocate use elucidate drivers behind animal derive unbiased estimates monitoring programs.

Fractal image perception provides novel insights into hierarchical cognition

Hierarchical structures play a central role in many aspects of human cognition, prominently including both language and music. In this study we addressed hierarchy in the visual domain, using a novel paradigm based on fractal images. Fractals are self-similar patterns generated by repeating the same simple rule at multiple hierarchical levels. Our hypothesis was that the brain uses different re...

Spatial and temporal variation in amphibian metacommunity structure in Chiapas, Mexico

Amphibians are known to be sensitive to environmental change but their responses at the level of metacommunities to short-term environmental variability are poorly understood. We used field data from two protected areas, La Pera and Nahá (Chiapas, Mexico) to test for variation in metacommunity properties for two consecutive years (2009 and 2010). Amphibians and accompanying environmental data w...

Multi-Class Community Structure within a Temperate Freshwater Wetland Complex: Evidence for the Metacommunity

Wetlands are ecologically valuable and complex systems that both link and buffer aquatic and terrestrial systems. Spatial aspects and metacommunity concepts help explain community structure and dynamics, but metacommunity dynamics have not been applied to multiple interacting classes of organisms in temperate wetlands. The aim of this study was to 1) quantify significant patterns of wetland com...

Insights into role of microRNAs in cardiac development, cardiac diseases, and developing novel therapies

Objective(s): MicroRNAs (miRNAs) are a subfamily of small noncoding RNAs that play a variety of roles in regulating gene expression in nearly all organisms. They affect different biological pathways by post-transcriptionally regulating mRNAs. Aside from miRNAs’  role in maintaining cellular homeostasis, their perturbation is related to several pathologic states and dis...
