Endocrine disrupting chemicals (EDCs) are ubiquitous in aquatic and terrestrial environments. The main objective of this review was to summarize the current knowledge impacts EDCs on reproductive success wildlife humans. examples selected often include a retrospective assessment over time discern how effects have changed last several decades. Collectively, evidence summarized here within reinforce concept that reproduction humans is negatively impacted by anthropogenic chemicals, with altering endocrine system function. These observations interfering different aspects axis particularly pronounced for species corroborated laboratory-based experiments (i.e. fish, amphibians, birds). Noteworthy, many these same indicators also observed epidemiological studies mammalian Given vast array strategies used animals, it perhaps not surprising no single disrupted target predictive effects. Nevertheless, there some general features control reproduction, particular, critical role steroid hormones play processes confer high degree susceptibility environmental chemicals.

Review: Toward management of urban ponds for freshwater biodiversity

Abstract Many cities around the world are expanding and this trend in urbanization is expected to sharply increase over coming decades. At same time, integration of green blue spaces widely promoted urban development, potentially offering numerous benefits for biodiversity. This particularly relevant waterbodies, a type ecosystem present most cities. However, site managers often lack knowledge base promote biodiversity these which generally created provide other services. To address this, our review presents guidelines promoting ponds. We found total 516 publications indexed ISI Web Sciences related topic, 279 were retained purposes review. The ponds, measured by species richness, appears be lower than rural ponds; however, ponds support threatened species. Furthermore, if well managed, have potential much greater they currently do. Indeed, shows that range factors can impair or pond biodiversity, including many easily controlled managers. Local include design (surface area, depth, banks margins, shade, shoreline irregularity), water quality (conductivity, nutrients, heavy metals), hydroperiod biotic characteristics (stands vegetation, fish, invasive species).

Sewage pollution, declining ecosystem health, and cross-sector collaboration

Published: Feb. 23, 2021

It is well established that a global sanitation crisis threatens humans. By comparison, much less attention has been given to address the effects of this on health ecosystems. We provide examples how sewage can affect natural ecosystems and where hotspots in contamination commonly overlap with these habitats. highlight issues for some major spanning across terrestrial, aquatic, coastal realms. Recent studies reveal untreated poorly treated elevates concentrations nutrients, pathogens, endocrine disruptors, heavy metals, pharmaceuticals show many large areas (10,000's km2) globe high levels extensively occurrence coral reefs, salt marshes, fish-rich river systems. Given extent pollution near habitats, conservation biologists managers must threat. However, because its size, conservationists cannot solve problem alone. therefore argue combine forces human sector create cross-disciplinary synergisms innovation efficiency. New management solutions are emerging, such as waste-free toilets resource recovery generate fuel drinking water; but more needed - demand will most effectively be reached through cross-sector collaboration.

Urbanization drives the evolution of parallel clines in plant populations

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2016, Volume and Issue: 283(1845), P. 20162180 - 20162180

Published: Dec. 22, 2016

Urban ecosystems are an increasingly dominant feature of terrestrial landscapes. While evidence that species can adapt to urban environments is accumulating, the mechanisms through which urbanization imposes natural selection on populations poorly understood. The identification adaptive phenotypic changes (i.e. clines) along gradients would facilitate our understanding selective factors driving adaptation in cities. Here, we test for clines by sampling frequency a Mendelian-inherited trait—cyanogenesis—in white clover ( Trifolium repens L.) four Cyanogenesis protects plants from herbivores, but reduces tolerance freezing temperatures. We found cyanogenic within decreased towards centre three A field experiment indicated spatial variation herbivory unlikely explain these clines. Rather, colder minimum winter ground temperatures areas compared with non-urban areas, caused reduced snow cover cities, may select against cyanogenesis. In city no cline, high might protect damage centre. Our study suggests adapting gradients, regional climatic patterns ultimately determine whether occurs.

Summary Steroid hormones modulate development, reproduction and communication in eukaryotes. The widespread occurrence persistence of steroid have attracted public attention due to their endocrine‐disrupting effects on both wildlife human beings.

ABSTRACT Steroids are abundant growth substrates for bacteria in natural, engineered, and host-associated environments. This study analyzed the distribution of aerobic 9,10-seco steroid degradation pathway 346 publically available metagenomes from diverse Our results show that steroid-degrading globally distributed prevalent particular environments, such as wastewater treatment plants, soil, plant rhizospheres, marine environment, including sponges. Genomic signature-based sequence binning recovered 45 metagenome-assembled genomes containing a majority genes. Only Actinobacteria Proteobacteria were identified degraders, but we several alpha- gammaproteobacterial lineages not previously known to degrade steroids. Actino- proteobacterial degraders coexisted wastewater, while soil rhizosphere samples contained mostly actinobacterial ones. Actinobacterial found deep ocean samples, ones other Isolation sponges confirmed their presence. Phylogenetic analysis key proteins suggested biochemical novelty shows ecological significance well taxonomic diversity bacterial has so far been largely underestimated, especially environment.
