Inventario de áreas verdes urbanas. Base de datos con localización, condición y arbolado de San Nicolás de los Garza, Nuevo León, México

<p>Se genera una base de datos y un reporte t&eacute;cnico para el Municipio de San Nicol&aacute;s de los Garza, el cual es uno de 12 municipios que conforman el &Aacute;rea Metropolitana de Monterrey (AMM), en Nuevo Le&oacute;n al Noreste de M&eacute;xico. Esta investigaci&oacute;n se realiz&oacute; por el inter&eacute;s genuino del Departamento de Geom&aacute;tica del Instituto de Ingenier&iacute;a Civil de la UANL,&nbsp;en mejorar la informaci&oacute;n geoespacial de los espacios abiertos y &aacute;reas verdes urbanas (AVU) que se encuentran dentro del AMM. Alineado a la importancia brindada a este tema&nbsp;por la Organizaci&oacute;n de las Naciones Unidas (ONU) a trav&eacute;s de las metas de sustentabilidad al 2030. Reconociendo que este tipo de espacios p&uacute;blicos&nbsp;son administrados por la alcald&iacute;a, y que enfrentaban problem&aacute;ticas como la falta de datos o de claridad metodol&oacute;gica, se ha homologado la metodolog&iacute;a a la generada en 2018 para el municipio de Escobedo, N.L. En San Nicol&aacute;s el &aacute;rea total municipal representa el 0.1% de la superficie del estado, con un 95% de &aacute;rea urbanizada.&nbsp; Los datos reportados como oficiales previos al presente estudio, carecen de un sustento metodol&oacute;gico y de una base de datos de origen que proporcione las herramientas para tomar decisiones sobre la conservaci&oacute;n y/o manejo de las &aacute;reas verdes del municipio. El objetivo del estudio fue desarrollar un inventario de &aacute;reas urbanas verdes que eran gestionadas por el municipio con una base de sistemas de informaci&oacute;n geogr&aacute;fica (SIG) para determinar su &aacute;rea en metros cuadrados y analizar su condici&oacute;n en la &eacute;poca de muestra (agosto del 2017) y validadas en campo con el uso de Google Earth y con informaci&oacute;n obtenida en parques muestra por medio de veh&iacute;culos a&eacute;reos no tripulados (VANT) durante el 2020. El estudio presenta los resultados de la geometr&iacute;a de los pol&iacute;gonos, obtenidos de la clasificaci&oacute;n supervisada de una imagen de WorldView-3 y el an&aacute;lisis del &Iacute;ndice de Vegetaci&oacute;n de Diferencia Normalizada (NDVI) como una primera evaluaci&oacute;n que determina la l&iacute;nea de base. El proceso de validaci&oacute;n se realiz&oacute; para al menos el 85% de las &aacute;reas y su superficie. El estudio concluy&oacute; que el municipio de San Nicol&aacute;s cuenta con una densidad de 8.19 m2 de &aacute;rea verde por habitante. La base de datos concentra m&aacute;s de 800 pol&iacute;gonos de &aacute;reas verdes que van desde 13.14 m2 hasta 8.88 hect&aacute;reas y s&oacute;lo el 10% de estos pol&iacute;gonos son mayores de una hect&aacute;rea. Para los pol&iacute;gonos correspondientes a &aacute;reas verdes del municipio se determin&oacute; una cantidad de &aacute;rboles total de 21,348.</p>

A new subgenus of Bembidion Latreille from México and Guatemala, with descriptions of two new species (Coleoptera: Carabidae)

<p>A new subgenus of <em>Bembidion, Geocosmius </em>subg. nov.,<em> </em>is described from forests of México and Guatemala.  <em>Geocosmius</em> includes <em>Bembidion nahuala</em> Erwin as its type species, as well as <em>B. franiae</em>Erwin, <em>B. elescarabajo</em> sp. nov., and additional forms similar to <em>B.</em> <em>nahuala</em>. In México this subgenus is widespread, ranging from Chiapas and Oaxaca north and west to Jalisco, Querétaro, and Hidalgo; most specimens are from cloud forests between 1700–2700m in elevation.  A molecular phylogenetic analysis based upon eight genes indicates that <em>Geocosmius</em> is the sister group of subgenus <em>Liocosmius</em>, from western North America.  In addition, a new species of subgenus <em>Liocosmius</em>, <em>B. cachagua</em> sp. nov., is described from three localities in California.  Illumina sequencing was used to acquire DNA sequences of six pinned, dried specimens, which ranged in age from 24 to 57 years, allowing the phylogenetic placement of four of the studied species to be determined.</p>

May 2014 in A New Subgenus of Bembidion Latreille from México and Guatemala, with Descriptions of Two New Species (Coleoptera: Carabidae)

May 2014, John Sproul and I searched at multiple known localities for this species, including at Hastings Natural History Reserve, Pinnacles National Park, around Santa Barbara, and at many other localities in between. We searched in typical Liocosmius microhabitats (including steep sand banks in partial shade), with no success. Along Finch Creek in Hastings Natural History Reserve, the only Bembidion in those microhabitats was B. iridescens LeConte; in nearby micro- habitats along the creek shore were three species of Bembidion: B. californicum Hay- ward, B. perspicuum LeConte, and B. lugubre LeConte. FIGURE 9. Map of California showing the geographic distribution of Bembidion cachagua.

FIGURE 4. Phylogenetic results, focusing on subgenera Geocosmius, Liocosmius, and Trechonepha. (A) A portion of the maximum likelihood tree inferred from the concatenated, eight-gene matrix. Numbers of the branches are maximum likelihood bootstrap percentages; bootstrap values within most of Liocosmius not shown. Other bembidiines omitted from the image. Scale bar 0.1 units, as calculated by IQ-TREE. (B) Support for various clades, measured with bootstrap support percentages from maximum likelihood phylogenetic analyses. One or two values are given in each cell. If the bootstrap support percentage is 90 or more, only that value is listed. If bootstrap support is less than 90, two values are listed: the bootstrap support for the clade, followed by a negative value which is the bootstrap support against the clade, as measured by the bootstrap value for the contradictory clade with the highest support value. The "8g" column shows the support values for the concatenated, eight-gene matrix. "-" indicates only one species is included, and thus support for that clade cannot be measured.

FIGURE 3 in A New Subgenus of Bembidion Latreille from México and Guatemala, with Descriptions of Two New Species (Coleoptera: Carabidae)

FIGURE 3. Overview of maximum likelihood bootstrap tree of Bembidiini based upon the concatenated, eight-gene matrix, showing position of the subgenera Geocosmius, Liocosmius, and Trechonepha. Taxon names in paler gray are genera of Bembidiini other than Bembidion; all other taxa are subgenera, subgeneric complexes, or subgeneric series of Bembidion. Triangles (clades) have their area approximately proportional to the number of species included in the analysis. Details within each clade are presented in the files submitted to Data Dryad (see Data availability section). Values below branches are the bootstrap support for that clade, expressed as a percentage.
