Data from portable seismographs and a permanent local network (called RESCO) are used to locate the aftershocks of October 9, 1995 Colima‐Jalisco earthquake (M w 8.0). The maximum dimension aftershock area, which is rectangular in shape, 170 km × 70 km. Our study shows that mainshock nucleated ∼24 south Manzanillo, near foreshock 6, 5.8), propagated ∼130 NW ∼40 SE. area lies offshore oriented parallel coast. observed subsidence coast consequence this rupture area. reach unusually close...
Bats are hosts to a large variety of viruses, including many capable cross-species transmissions other mammals, humans. We characterized the virome in guano from five common bat species 9 Northern California roosts and pool 5 individual bats. Genomes belonging 14 viral families known infect mammals 17 infecting insects or unknown tropism were detected. Nearly complete genomes novel parvovirus, astrovirus, nodavirus, circular Rep-encoding single-stranded DNA (CRESS-DNA) densoviruses, more...
Developmental science has made great strides in understanding how child socioeconomic circumstances shape outcomes a range of domains. Researchers have argued we need to operationalize clearly and consistently, more recently, ensure are culturally responsible way. However, there is bring together these perspectives understand should operationalise measure disadvantage ways that both responsive precise, striking balance between mechanistic insight policy relevance. This paper highlights three...
Abstract Estimating the magnitude of dome eruptions is one main challenges in volcano monitoring. Although modern monitoring networks are place at many dome‐building volcanoes, type and occurrence explosive activity scale commonly estimated by visual inspection. Quantifying deformation volcanoes explosions highly valuable, not only for enabling provision early warnings but also facilitating an understanding physics as demonstrated this study most active Mexico. The Volcán de Colima currently...
The Mw 7.4 Tecoman earthquake occurred off the Pacific coast of state Colima, Mexico on 22 January 2003 (Figure 1). It was felt very strongly in city Colima and towns Armeria. left 21 persons dead. About 15,000 houses suffered damage; roughly 3,000 these experienced severe damage. most significant damage observed adobe unreinforced brick masonry houses. Very few cases structural failure were recorded engineered buildings. Ground motion lakebed zone City, about 540 km from epicentral zone,...
Studies at renewable energy sites often attempt to estimate avian and bat fatalities or fatality rates (e.g., fatalities/megawatt [MW]/year). However, searcher efficiency level of survey effort among are variable. We evaluated how proportion area surveyed affected precision estimates probability detecting rare an endangered species). measured searcher-efficiency human dog-handler teams for 3 types: feather spots, small carcasses, large carcasses. also created high low scenarios evaluate...
A proposed conceptual model of Vulcanian explosions describes the volcanic explosion process as consisting two stages (the movement fragmented magma to surface and a subsequent explosion) is constrained by four source parameters inferred from broadband seismic records counter force eruption F acting in conduit before an governing surface, time D 1 explosion, duration 2 , energy E explosion). Our paper discusses, within framework model, scaling relationship 135 occurring at Mexican andesitic...
An activity-level monitoring platform is developed using a non-contact Doppler radar sensor. The need for assistive living and smart home technologies will arise due to the increase in aging population, sensing have potential revolutionize healthcare delivery. Based on developments at University of Florida's Radio Frequency Circuits Systems Research Laboratory, relevant information how active people are during day based their physiological movements obtained algorithms A continuous 5.8 GHz...
We use coseismic displacements and aftershock information from Global Positioning System (GPS) measurements at 27 sites in western Mexico a 12-station local seismic network to determine the characteristics of 2003 January 22 Mw = 7.2 subduction thrust earthquake near Tecomán, Colima, Mexico. Estimates moment, slip direction best-fitting distribution are derived by optimizing fit GPS for 3-D finite element mesh that simulates study area. The calculated moment release is 9.1 × 1019 N m (Mw...
Conservation-reliant species require perpetual management by humans to persist. But do that persist largely in human-dominated landscapes actually conditions maintained humans? Because most extant populations of giant gartersnakes (Thamnophis gigas) inhabit the highly modified rice agricultural regions Sacramento Valley, we sought evaluate whether are indeed a conservation-reliant dependent on maintenance agriculture and its infrastructure for their continued existence. Specifically,...
Abstract Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is a viral pathogen that quickly became global pandemic in the winter of 2020–2021. In response, governments issued social distancing orders to minimize transmission by reducing community contacts. We tested efficacy this at state level during first months United States. utilized data on daily SARS‐CoV‐2 case numbers and human mobility (anonymized, aggregated cell phone location stratified into six categories used as an...

There has been significant progress in understanding the effects of childhood poverty on neurocognitive development. This captured attention policymakers and promoted progressive policy reform. However, prevailing emphasis harms associated with may have inadvertently perpetuated a deficit-based narrative, focused presumed shortcomings children families poverty. focus can unintended consequences for (e.g., overlooking strengths) as well public discourse focusing individual rather than...
Abstract As a migratory, cryptic, foliage-roosting bat with mostly solitary roosting behavior we have an incomplete understanding of the social hoary bat, Lasiurus cinereus . In this species most interactions between conspecifics are thought to involve mating or territorial disputes. Developing more complete would provide critical insight address conservation challenges including high fatality rates from wind turbines during period fall migration. We tested response bats conspecific call...
Abronia anzuetoi es una lagartija endémica al volcán de Agua en Sacatepéquez, Guatemala. La especie era conocida previamente por únicamente seis ejemplares todos correspondientes a la serie tipo. El último espécimen conocido fue colectado 1974. Nosotros reportamos el redescubrimiento luego colectar cinco nuevos ejemplares, 48 años después su avistamiento. Los fueron colectados dos localidades ubicadas falda oeste del Agua, inmediaciones Alotenango, Nuestro reporte representa extensión rango...
