The Antarctic is considered to be a pristine environment relative other regions of the Earth, but it increasingly vulnerable invasions by marine, freshwater and terrestrial non-native species. Peninsula region (APR), which encompasses Peninsula, South Shetland Islands Orkney Islands, far most invaded part Antarctica continent. risk introduction invasive species APR likely increase with predicted increases in intensity, diversity distribution human activities.

The manuscript assesses the current and expected future global drivers of Southern Ocean (SO) ecosystems. Atmospheric ozone depletion over Antarctic since 1970s, has been a key driver, resulting in springtime cooling stratosphere intensification polar vortex, increasing frequency positive phases Annular Mode (SAM). This increases warm air-flow East Pacific sector (Western Peninsula) cold air flow West sector. SAM as well El Niño Oscillation events also affect Amundsen Sea Low leading to...
Abstract Logged and disturbed forests are often viewed as degraded depauperate environments compared with primary forest. However, they dynamic ecosystems 1 that provide refugia for large amounts of biodiversity 2,3 , so we cannot afford to underestimate their conservation value 4 . Here present empirically defined thresholds categorizing the logged forests, using one most comprehensive assessments taxon responses habitat degradation in any tropical forest environment. We analysed impact...
Subsistence harvesting and wild food production by Athabascan peoples is part of an integrated social–ecological system interior Alaska. We describe effects recent trends future climate change projections on the boreal ecosystem Alaska relate changes in services to subsistence. focus primarily moose, a keystone terrestrial subsistence resource villages that region. Although has affected forest, moose harvesting, high dependence village households persists. An historical account 20th century...
Climate warming and resource development could alter key Arctic ecosystem functions that support fish wildlife resources harvested by local indigenous communities. A different set of global forces - government policies tourism markets increasingly directs cash economies communities use to subsistence activities. Agent-based computational models (ABMs) contribute an integrated assessment community sustainability simulating how people interact with each other adapt changing economic...
In the emerging literature on resilience in relation to food security, a growing number of studies stress need expand our analysis beyond conventional socio-economic factors such as assets or social capital, and consider less tangible elements risk perception, self-efficacy aspiration. Drawing recent authors’ own experience, conceptual framework subjective is proposed. The helps locating element within wider conceptualization currently developed security clarify how it links more that...
Marine Spatial Planning (MSP) has become a priority for many states wanting to develop national blue economy plans and meet international obligations in response the increasing cumulative impacts of human activities climate change. In areas beyond jurisdiction (ABNJ), MSP is proposed as part package solutions multi-sectoral management at ocean basin scale. To facilitate planning, maps showing spatial distribution marine biological diversity are required. lacking data, like South Atlantic,...
Abstract Invasive non‐native species (INNS) are recognized as a major threat to island biodiversity, ecosystems, and economies globally. Preventing high‐risk INNS from being introduced is the most cost‐effective way avoid their adverse impacts. We applied horizon scanning approach identify potentially in United Kingdom Overseas Territories (OTs), ranging Antarctica Caribbean, Pacific Atlantic. High‐risk were identified according potential for arrival, establishment, likely impacts on...
Metabolic rate is a key component of energy budgets that scales with body size and varies large-scale environmental geographical patterns. Here we conduct an analysis standard metabolic rates (SMR) marine ectotherms across 70° latitudinal gradient in both hemispheres spanned collection temperatures 0-30 °C. To account for differences the skeletal composition between species, SMR was mass normalized to standard-sized (223 mg) ash-free dry individual. measured 17 species calcified...
The thermal reaction norms of 4 closely related intertidal Nacellid limpets, Antarctic (Nacella concinna), New Zealand (Cellana ornata), Australia (C. tramoserica) and Singapore radiata), were compared across environments with different temperature magnitude, variability predictability, to test their relative vulnerability scales climate warming. Lethal limits measured alongside a newly developed metric "duration tenacity", which was tested at temperatures calculate the norm limpet adductor...
The covalent attachment of biomolecules onto surfaces represents a step toward the improvement biomaterial properties by providing relevant biological signals interest to cell culture or tissue environment. chemistries involved, however, often attach proteins surface in random fashion, rather than conformation orientation most easily recognized cells and other both vitro vivo. An alternative approach is take advantage natural interactions bind orient biomolecule "naturally," thereby...
Abstract A wide array of technologies exist for the characterization and quantification molecules present at surfaces. We have used several these experimental instrumental techniques analysis a novel biomaterial surface. Osteopontin, an extracellular matrix molecule involved in wound‐healing processes, has been chosen as relevant model protein to immobilize onto poly(2‐hydroxyethyl methacrylate) [poly(HEMA)]. Electron spectroscopy chemical time‐of‐flight secondary ion mass spectrometry were...
Abstract This research explores the consequences of out-migration for sending communities in rural Alaska. In particular, it describes relationship between female and community viability, by comparing age–sex structures Alaska Native villages that are growing with decline. The paper discusses its connection to school closure. It provides a detailed description from northern Alaska, using data several household surveys better understand migrants. Villages decreasing size show loss adult women...
Carbon-rich habitats can provide powerful climate mitigation if meaningful protection is put in place. We attempted to quantify this around the Tristan da Cunha archipelago Marine Protected Area. Its shallows (<1000 m depth) are varied and productive. The 5.4 km2 of kelp stores ~60 tonnes carbon (tC) may export ~240 tC into surrounding depths. In deep-waters we analysed seabed data collected from three research cruises, including mapping, camera imagery, oceanography benthic samples...
Abstract The functional stability of ecosystems depends greatly on interspecific differences in responses to environmental perturbation. However, perturbation are not necessarily invariant among populations the same species, so intraspecific variation might also contribute. Such inter-population response diversity has recently been shown occur spatially across species ranges, but we lack estimates extent which individual an entire community have that vary through time. We assess this using...
The present paper examines the relationship between public school teacher salaries and racial concentration segregation of students in district. A particularly rich set control variables is included to better measure effect characteristics. Additional analyses Metropolitan Statistical Area fixed effects longitudinal salary data. results are generally consistent with a positive compensating wage differential for working districts higher percentage Black Latino students. also suggest that more...

Plasticity in behavior is mirrored by corresponding plasticity the brain many songbird species. In some species, song system nuclei (Phillmore et al. [2006]: J Neurobiol 66:1002-1010) are larger birds breeding condition than nonbreeding condition, possibly due to increased vocal output spring. FOXP2, a transcription factor associated with language expression and comprehension humans learning songbirds, also shows plasticity. FoxP2 Area X, region important for sensorimotor integration,...
