Features of possible regional ionospheric memory manifested themselves at low-latitudes under solar eclipse conditions.
Motivation The database initiated by the Mountain Invasion Research Network (MIREN) is one of the few globally implemented standardized vegetation surveys in mountains. The focus is on collecting plant species occurrences at 5‐year intervals along and adjacent to mountain roads spanning elevational gradients, with the goal of providing critical information about the ongoing spread of non‐native plants and the potential impacts...
Cryptic coral reef microhabitats and the functional role of brittle stars in biogenic sediment generationNARA Subscribed
Recent studies have highlighted the ecological importance of cryptic habitat space on coral reefs. These microhabitats, ranging from framework cavities to intra-branch space within marine macroalgae, can harbour diverse and ecologically relevant taxa. Here we show that brittle stars, ubiquitous across such cryptic habitats (reported densities exceeding 100 ind. m −2 ), represent an important, but previously neglected, source o...
Participative Selection of Wastewater Treatment Systems in Informal Settlements: An Innovative Tool to Address UncertaintyNARA Subscribed
Peri-urban settlements are characterized by inadequate wastewater management. Decentralized wastewater management systems are promising alternatives for reducing pollution from untreated sewage entering receiving water bodies, but the social, economic, and environmental conditions in peri-urban settlements require careful technology selection to ensure sustainability. Several domestic wastewater technology selection tools exis...
Quiet Signals of Burmeister's Porpoises ( Phocoena spinipinnis ) Recorded in Chile and PeruNARA Subscribed
Burmeister's porpoises are cryptic and challenging to detect visually. More information on their acoustic signals could facilitate the use of passive acoustic monitoring (PAM) and help to better understand their ecology. Here, clicks were recorded from two different Burmeister's porpoise populations, one in Chile and the other in Peru, using a 4‐channel hydrophone array and a single‐channel hydrophone recorder. Burmeister's po...
Inactivation of Avian Influenza Virus in Raw Milk KefirNARA Subscribed
Both highly pathogenic avian influenza virus (HPAIV) and its viral RNA have been detected in raw milk during the ongoing outbreak in dairy cows. While pasteurization effectively inactivates the virus in milk, comparatively little has been published on AIV inactivation in fermented dairy products made from raw milk. We evaluated the viability of two isolates of low pathogenic avian influenza virus (LPAIV) during fermentation of...
The Role of Peripheral Regions in Shaping the Phylogeography of the Bear's Ear Complex Across the AlpsNARA Subscribed
Aim Peripheral regions of the Alps are often overlooked in molecular studies, yet they may play a major role in shaping the current distribution of species and genetic lineages. Location Europe. Taxon Angiosperms (Primulaceae: Primula ). Methods By focusing on the bear's ear ( Primula auricula ) complex as model species, we used genetic inferences for population genetic structure and performed genetic reconstructions, species...
Tropical Montane Cloud Forests Have High Resilience to Five Years of Severe Soil DroughtNARA Subscribed
Tropical montane cloud forests (TMCFs) are globally important ecosystems, acting as large carbon sinks and supporting exceptional biodiversity. However, climate‐driven declines in rainfall threaten these forests, but their responses to long‐term soil moisture deficit remain poorly understood. We implemented a 5‐year throughfall exclusion (TFE) experiment in a Peruvian TMCF, reducing soil moisture by 69.1% across a 0.09 ha plot...
The use of diagnostic tools to assess the risks of chemicals to freshwater ecosystems: towards a unified evaluation frameworkNARA Subscribed
The risk assessment of chemicals relies on multiple tools to quantify the ecological responses of ecosystems to existing chemical pollution. These tools are broadly categorized into three major groups: toxic pressure assessments, bioassays, and ecological monitoring. Here, we examine the strengths and limitations of these approaches, their current level of implementation for freshwater ecosystems across Europe, and their abili...
Impact of environmental gradients on juvenile coral demography across the Great Barrier Reef and Torres StraitNARA Subscribed
Demographic rates of juvenile corals are critical to reef recovery, yet their variation across environmental gradients remains understudied. Over three years, we assessed juvenile coral vital rates across the Great Barrier Reef (GBR) and Torres Strait (TS), spanning 14° latitude and diverse inshore to offshore environments. Environmental conditions varied, with annual temperatures ranging 24–28 °C, high turbidity in the southe...
