TL;DR: Biome-wide relationships between temperature, moisture and seven key plant functional traits across the tundra and over time show that community height increased with warming across all sites, whereas other traits lagged behind predicted rates of change.
Abstract: The tundra is warming more rapidly than any other biome on Earth, and the potential ramifications are far-reaching because of global feedback effects between vegetation and climate. A better understanding of how environmental factors shape plant structure and function is crucial for predicting the consequences of environmental change for ecosystem functioning. Here we explore the biome-wide relationships between temperature, moisture and seven key plant functional traits both across space and over three decades of warming at 117 tundra locations. Spatial temperature-trait relationships were generally strong but soil moisture had a marked influence on the strength and direction of these relationships, highlighting the potentially important influence of changes in water availability on future trait shifts in tundra plant communities. Community height increased with warming across all sites over the past three decades, but other traits lagged far behind predicted rates of change. Our findings highlight the challenge of using space-for-time substitution to predict the functional consequences of future warming and suggest that functions that are tied closely to plant height will experience the most rapid change. They also reveal the strength with which environmental factors shape biotic communities at the coldest extremes of the planet and will help to improve projections of functional changes in tundra ecosystems with climate warming.

TL;DR: Neuropathologic and other data suggest two major pathogenetic pathways of HIV‐associated CNS damage: systemic and local increase of the virus load leads to HIV encephalitis or HIV leukoencephalopathy; this is corroborated by prominent HIV production within such lesions.
Abstract: Neuropathology has defined novel HIV-specific diseases at tissue level: HIV encephalitis and HIV leukoencephalopathy. Both occur usually in the later stages of the AIDS infection and consistently demonstrate large amounts of HIV products. In contrast to this HIV-specific neuropathology, HlV-asso-ciated neuropathology features unspecific syndromes with disputed relation to HIV infection: myelin pallor, vacuolar myelopathy, vacuolar leukoencephalopathy, lymphocytic meningitis, and diffuse poliodystrophy. All types of neuropathology may contribute to clinical manifestation according to severity, extent, and distribution of lesions, but clinico-pathologic correlation may be poor in the individual case. Neuropathologic and other data suggest two major pathogenetic pathways of HIV-associated CNS damage: First, systemic and local increase of the virus load leads to HIV encephalitis or HIV leukoencephalopathy; this is corroborated by prominent HIV production within such lesions. Second, neuronotoxicity by HIV proteins or factors secreted from infected cells is supported by histological changes of diffuse poliodystrophy and by morphometric loss of frontocortical neurons.

TL;DR: Global sampling of microbial communities associated with wastewater treatment plants and application of ecological theory revealed a small, core bacterial community associated with performance and provides insights into the community dynamics in this environment.
Abstract: Microorganisms in wastewater treatment plants (WWTPs) are essential for water purification to protect public and environmental health. However, the diversity of microorganisms and the factors that control it are poorly understood. Using a systematic global-sampling effort, we analysed the 16S ribosomal RNA gene sequences from ~1,200 activated sludge samples taken from 269 WWTPs in 23 countries on 6 continents. Our analyses revealed that the global activated sludge bacterial communities contain ~1 billion bacterial phylotypes with a Poisson lognormal diversity distribution. Despite this high diversity, activated sludge has a small, global core bacterial community (n = 28 operational taxonomic units) that is strongly linked to activated sludge performance. Meta-analyses with global datasets associate the activated sludge microbiomes most closely to freshwater populations. In contrast to macroorganism diversity, activated sludge bacterial communities show no latitudinal gradient. Furthermore, their spatial turnover is scale-dependent and appears to be largely driven by stochastic processes (dispersal and drift), although deterministic factors (temperature and organic input) are also important. Our findings enhance our mechanistic understanding of the global diversity and biogeography of activated sludge bacterial communities within a theoretical ecology framework and have important implications for microbial ecology and wastewater treatment processes.
