Extent of white-rot litter mats formed by basidiomycete fungi in Puerto Rico decreased in response to disturbances—a simulated hurricane treatment executed by canopy trimming and debris addition in 2014, a drought in 2015, a treefall, and two hurricanes 10 days apart in September 2017. Percent fungal litter mat cover ranged from 0.4% after Hurricanes Irma and Maria to a high of 53% in forest with undisturbed canopy prior to...AuthorsD.

- Forestry and forest ecology research potentially lags behind related fields such as ecology, biodiversity, and conservation research in the employment of open-source software solutions, specifically the R programming language. A direct comparison of the last decade of published research literature from the top 20 ecology and forestry journals shows that R is utilized in over 30% of the literature for ecology, yet in less than 10% of the forestry literature. Open-source computing environments, such as R, Python, and Julia, increase the visibility and reproducibility of scientific research...AuthorsJeff W. Atkins, Atticus E.L.

- Peatlands contain a significant fraction of global soil carbon, but how these reservoirs will respond to the changing climate is still relatively unknown. A global picture of the variations in peat organic matter chemistry will aid our ability to gauge peatland soil response to climate. The goal of this research is to test the hypotheses that (a) peat carbohydrate content, an indicator of soil organic matter reactivity, will increase with latitude and decrease with mean annual temperatures, (b) while peat aromatic content, an indicator of recalcitrance, will vary inversely, and (c)...AuthorsBrittany A.

- Rapid global vegetation greening has been observed for the past two decades, but its implications to the hydrological cycle are not well understood in many regions, including the Yangtze River Basin (YRB). This study used a remote sensing-driven ecosystem model, the Coupled Carbon and Water model, to fully examine the individual and combined hydrological effects of vegetation and climate changes through a series of modeling experiments. During the study period (2001–2018), the vegetation showed a significant greening trend with the mean annual normalized difference vegetation index...AuthorsJiehao Zhang, Yulong Zhang, Ge Sun, Conghe Song, Jiangfeng Li, Lu Hao, Ning LiuSourceWater Resources ResearchYear2022
- Butterfly bush (Buddleja sessiliflora) reaches its northern range in southeast Arizona and herbarium records document seven historic localities from Pima and Santa Cruz counties. We visited all populations between 2014 and 2018, except for one reported from the Tohono O’odham Nation to discover that five historic localities were verified to be extant, and an additional locality was discovered in 2018. A total of 22 plants were documented during this study. All surveyed populations are isolated to 6–15 m areas and contained between one and seven plants. No propagules were found, except for...AuthorsJames T. Verrier, Iris E. RoddenKeywordsSourceIn: Neary, D. G.; Gottfried, G. J., eds.

- El estado de Sonora cuenta con 126 especies de mamíferos, de las cuales, 18 especies (14.2%) corresponden a carnívoros. El presente estudio se efectuó en Rancho “La Volanta”, ubicado a 18.6 kilómetros al noreste de Bacoachi, Sonora, en la Cuenca del Río Sonora, y colindando con Sierra Los Ajos, que forma parte de la APFF Bavispe, un área natural protegida federal. Este estudio se llevó a cabo bajo la técnica de foto-trampeo, con la cual fue posible obtener información durante las 24 horas del día y sin ser invasiva para la fauna silvestre. Se instalaron 12 cámaras-trampas en 12 sitios...AuthorsSaul Abraham Amador AlcalaKeywordsSourceIn: Neary, D. G.; Gottfried, G. J., eds.

- La Reserva Jaguar del Norte (RJN) se creó en 2003 con la finalidad de proteger la población más norteña de jaguar (Panthera onca), y a otras especies igualmente importantes que habitan en el territorio de esa región. Con el propósito de generar información de la población de felinos silvestres: jaguar, puma (Puma concolor), ocelote (Leopardus pardalis), y gato montes (Lynx rufus) se realizaron monitoreos con 92 cámaras-trampa dentro de la RJN. Se obtuvo un esfuerzo de muestreo de 21,170 días-cámaras para los siete periodos en los que se dividió el estudio (enero-diciembre del 2014).

- There are 55 Sky Island mountain ranges or mountain complexes connected by oak woodland corridors in the Madrean Archipelgo between the Sierra Madre Occidental in Sonora and the Mogollon Rim in Arizona. Thirty-two of them ar in Sonora, Mexico. In 2009 Sky Island Alliance began the Madrean Archipelago Biodiversity Assessment (MABA) Program to document the biodiversity of Sonoran Sky Islands. MABA biotic inventory Expeditions explored nine Sky islands, and Mini-Expedtions to three other areas. All observations of animals and plants are publicly available in the MABA database. In 2015...AuthorsThomas R. Van Devender, Noah Horton, Dale S. TurnerKeywordsSourceIn: Neary, D. G.; Gottfried, G. J., eds.

- Se presentan datos de un inventario exploratorio de los picudos (Coleoptera: Curculionoidea) presentes en las inmediaciones de Mesa Tres Ríos, municipio de Nácori Chico, Sonora, México. La localidad se encuentra a 1,880 m sobre el nivel del mar. Se utilizó una red de golpeo para la captura de los organismos (Márquez-Luna 2005). Se realizaron 41 muestreos en área de estudio de 2,050 m2 aproximadamente, representando cuatro diferentes ecosistemas (pino, pinoencino, encino y vegetación riparia), y durante un periodo de recolecta del 26 de junio al 30 de septiembre de 2017.

- There are a multitude of innovative strategies available to land managers that can help facilitate landscape-level conservation in the face of expected changes in human population growth, increasing temperature, shifting rainfall patterns, and weather extremes. A good example involves Leslie Canyon National Wildlife Refuge in Cochise County, Arizona. Here, the U.S. Fish and Wildlife Service (Service) has worked effectively with others to expand protection, conservation, and species recovery activities beyond the 2,765 ac (1,119 ha) Refuge owned by the Service, extending those efforts onto...AuthorsWilliam R.
