We evaluated the influence of pack stock (i.e., horse and mule) use on meadow plant communities in Sequoia and Yosemite National Parks in the Sierra Nevada of California. Meadows were sampled to account for inherent variability across multiple scales by: 1) controlling for among-meadow variability by using remotely sensed hydro-climatic and geospatial data to pair stock use meadows with similar...

Good environmental management needs evidence-based conservation measures, and those measures need both faunistical ecological information. Following this path, for the first time in Serbia, a research of spiders at Subotica Sandland was organised 2014 as base arguments landscape area. The were collected ten different habitats on sandy soil, period from 27th April till 30th October by pitfall tr...

N estuarine and marine ecosystems—e.g., seagrass meadows, marshes, and mangrove forests— serve many important functions in coastal waters. Most notably, they have extremely high primary and secondary productivity and support a great abundance and diversity of fish and invertebrates. Because of their effects on the diversity and productivity of macrofauna, these estuarine and marine ecosystems a...

Four species of Gymnadenia are native to Kosovo: G. conopsea , frivaldii nigra and odoratissima . In this study, field expedition data, phytosociological relevés, herbarium specimens along with extensive literature sources were used analyse vegetation ecological characteristics, habitat types, distributional patterns as well provide notes on conservation. is distributed throughout the country, ...

Seagrass meadows, one of the most important habitats for many marine species, provide essential ecological services. Thus, society must conserve seagrass beds as part of their sustainable development efforts. Conserving these ecosystems requires information on seagrass distribution and relative abundance, and an efficient, accurate monitoring system. Although narrow multibeam sonar systems (NMB...

BACKGROUND The Neptune grass, Posidonia oceanica (L.) Delile, 1813, is the most widespread seagrass of the Mediterranean Sea. This foundation species forms large meadows that, through habitat and trophic services, act as biodiversity hotspots. In Neptune grass meadows, amphipod crustaceans are one of the dominant groups of vagile invertebrates, forming an abundant and diverse taxocenosis. They ...

Seagrass meadows are valuable ecosystem service providers that are now being lost globally at an unprecedented rate, with water quality and other localised stressors putting their future viability in doubt. It is therefore critical that we learn more about the interactions between seagrass meadows and future environmental change in the anthropocene. This needs to be with particular reference to...

This study was performed in order to investigate the effects of taurine on cadmium poisoning in muscle, gill, and bone tissues of wild goldfish. For this experiment, 80 wild goldfish were divided into four experimental groups: 0.3 mg/L of cadmium and 0 mg/L of taurine (Group I), 0.3 mg/L of cadmium and 20 mg/kg of taurine (Group II), 0.3 mg/L of cadmium and 40 mg/L of taurine (Group III), and 0...

BACKGROUND Seagrass species in the tropics occur in multispecies meadows. How these meadows are maintained through species co-existence and what their ecological drivers may be has been an overarching question in seagrass biogeography. In this study, we quantify the spatial structure of four co-existing species and infer potential ecological processes from these structures. METHODS AND RESULT...
