Wrack supply represents the main organic input in sandy beaches ecosystems and is a common feature of around world. The chemical composition wrack important determining extent rate decay; particular, phenolic compounds may affect consumption rates by wrack-associated macrofauna and, consequently, modify nutrient processing recycling beaches. aim this research was to investigate possible links b...

Basking in the sun on an Australian beach, I began to feel a burning sensation from excessive UV irradiation and decided not to wait for the ozone layer to return. As first aid I scraped some algae and cyanobacteria from the blistering rocks and smeared them on my exposed skin. Why? Because these organisms contain sunscreen compounds to protect themselves from harmful doses of UV-B (280–315 nm)...

cells are active components in their environment and constantly adjusting their performance to improve extracellular milieu changing. this approach is reflected their tends of maintaining intracellular homeostasis. when the cells encounter stress or pathologic stimuli, they can undergo a new manner (adaptation) and new steady state for achieving viability and function. if the external stress is...

Two separate and distinct diamictite-rich units occur in the mixed carbonate-siliciclastic PolarisbreenGroup, which comprises the top kilometer of47 km of Neoproterozoic strata in the northeast of the Svalbard archipelago.The platformal succession accumulated on the windward, tropical to subtropical margin of Laurentia.The older PetrovbreenMember is a thin glacimarine diamictite that lacks a ca...

When monitoring the breeding ecology of birds, causes and times nest failure can be difficult to determine. Cameras placed near nests allow for accurate fate, but their presence may increase risk predation by attracting predators, leading biased results. The relative influence cameras on also depend habitat because predator numbers or behaviour change in response availability accessibility nest...

Summary The increasing pressure of anthropogenic development in areas with high natural value poses a huge challenge for wildlife conservation worldwide. Tagus estuary southern Portugal is among the most important wetlands migratory shorebirds East Atlantic Flyway (EAF). However, 2020 Portuguese government approved construction new Lisbon international airport at heart estuary. Intense aircraft...

The supralittoral zones of sandy beaches are particularly vulnerable to coastal development and other activities that cause localised habitat destruction. Supratidal species, such as peracarid crustaceans, which lack a pelagic larval phase tend avoid direct contact with the swash, therefore expected be distributed isolated populations, implications for their long-term survival. Genetic populati...

introduction: in the new concept of medical education, creativity development is an important goal. the aim of this research was toidentify a model for developing critical thinking among students with the special focus on learning environment and learning style. methods: this applied and cross-sectional study was conducted among all students studying in undergraduate and professional doctorate ...

Abstract A 200 m thick drill core penetrating the Givetian Hahnstätten Reef in southwestern Lahn Syncline (Rhenish Massif) was investigated. range of different depositional environments is described based on lithofacies and microfacies analysis. All all, nine types (FTs) are distinguished, which can include subfacies types. The majority these ultrapure carbonates represented by lime mudstone fe...

In response to the illicit drug trade that became especially troublesome in the late 1980's and early 1990's, a remarkable community anti-drug movement has formed, with groups becoming active in some of the most afflicted neighborhoods. Armed only with their courage and imagination, citizens have devised a variety of clever strategies and tactics to reclaim their streets and parks from drug tra...
