The alteration of forests due to anthropogenic activities and natural phenomena has led to the development of adaptive features so that organisms can tolerate it or use it to their benefit. In this study, saprotrophic fungi from a disturbed Juniperus deppeana forest were isolated and identified for in vitro propagation. Thirty-one specimens were collected and propagated on malt extract agar (EMA), potato dextrose agar (PDA), Kraft lignin agar (A-L) and mineral medium (MM). Taxonomic identification was performed on the basis of macro- and micromorphological characters of the basidiomata, and was complemented by phylogenetic analysis of ITS sequences. Only 7 strains grew under in vitro conditions; they grew best in EMA and PDA media. Room temperature (~22 °C) and preservation at 4 °C were the best conditions to maintain the viability of the strains. After 6 months, strains preserved in glycerol (15%) at 4° and -20 °C were not viable. The isolated fungi belong to the genera Agrocybe, Byssomerulius, Coniophora and Gymnopus. Given the environmental conditions where the strains were isolated, they represent new research prospects for obtaining biomolecules of biotechnological interest.

Barroetea A. Gray, previamente considerado como un género de Asteraceae, actualmente, con base en evidencia molecular se circunscribe como un grupo monofilético a escala de sección taxonómica dentro del género Brickellia. Aunque las relaciones filogenéticas a nivel molecular parecen estar resueltas, la morfología de sus especies no, por lo que esta revisión evalúa su variación morfológica y delimita cada una de sus especies. Se revisaron 242 ejemplares depositados en el Herbario Nacional de México (MEXU) y recolectas recientes, junto con protólogos e imágenes de los ejemplares tipo de las especies de la sección. Con base en 16 caracteres morfológicos y 153 individuos, se realizó un análisis multivariado con 7 morfoespecies reconocidas. Con ayuda de las similitudes morfológicas y la revisión de protólogos se concluye que Brickellia, sección Barroetea, incluye 6 especies (Brickellia brevipes, B. jimenezii,B. laxiflora, B. pavonii, B. sonorana y B. subuligera). La revisión taxonómica abarca una discusión de los cambios nomenclaturales, la designación de tipos nomenclaturales y la variación morfológica de cada una de las especies reconocidas. Se proporciona una clave taxonómica para su identificación y mapas de distribución geográfica.
Barroetea a. Gray，以前被认为是菊科的一个属，现在根据分子证据，在分类学上被划分为Brickellia属的一个单系类群。虽然在分子水平上的系统发育关系似乎已经解决，但物种的形态还没有解决，因此本综述评估了它们的形态变异，并界定了每个物种。本研究的目的是评估墨西哥国家植物标本馆(MEXU)保存的242个标本和最近收集的标本，以及该部分物种的原型和模式标本的图像。利用16个形态特征和153个个体，对7个形态种进行了多变量分析。通过形态学上的相似性和对原学家的回顾，我们得出结论，Brickellia, Barroetea切片，包括6个种(Brickellia brevipes, B. jimenezii,B。laxiflora, B. pavonii, B. sonorana和B. subbuligera)。分类修订包括对命名变化的讨论，命名类型的命名和每个已识别物种的形态变异。本研究的主要目的是确定该物种的地理分布。

Specimens of the amphibian species Leptodactylus melanonotus and Incilius marmoreus were collected in several localities in Colima State, Mexico, from July to October 2021. An undescribed species of nematode of the genus Cosmocerca was found in the intestine of L. melanonotus. The new species differs from every other species assigned to this genus by the combination of the following characters: absence of lateral alae in males, 5 plectanes, spicules size, and gubernaculum size and shape. This is the 39th species included in the genus worldwide and it is the second described in Mexico. Six helminth species were collected during this study: Rauschiella poncedeleoni, Cosmocerca colimense n. sp., Oswaldocruzia subauricularis, and Rhabdias sp. of L. melanonotus; Aplectana incerta and Oswaldocruzia pipiens of I. marmoreus.

La Reserva Jaguar del Norte es una propiedad privada ubicada en la sierra sonorense, dentro de una compleja matriz paisajística, con un amplio legado de uso ganadero. Esta región, identificada como prioritaria para la conservación, dispone de pocos datos sobre las trayectorias de cambio en la vegetación, un elemento clave para evaluar el impacto de las áreas naturales protegidas. Este trabajo presenta información acerca del efecto de las acciones con fines de conservación, sobre la composición de la vegetación tras el establecimiento de la reserva en el año 2003. Para ésto, se caracterizaron las comunidades vegetales presentes y se generaron clasificaciones supervisadas de cobertura con imágenes satelitales de mediana y alta resolución para realizar un análisis cambio de la cobertura vegetal (2003-2018). Las precisiones generales de las clasificaciones fueron iguales o superiores a 0.75, valor que aumentó al utilizar imágenes de mayor resolución espacial. El uso combinado de diferentes resoluciones espaciales presentó ventajas para entender las transiciones de composición entre diferentes comunidades vegetales. Las tendencias encontradas indicaron un aumento del matorral subtropical y una disminución del pastizal inducido, lo que refleja transformaciones hacia una mayor diversidad de especies y una reducción de posibles amenazas para la biodiversidad a nivel paisaje.

Las bases de datos florísticos constituyen herramientas clave para enriquecer el conocimiento sobre la diversidad vegetal de una región. Considerando la información que aportan, se llevó a cabo el registro de las plantas endémicas y características del estado de Guanajuato, dentro de una cuadrícula de 1° × 1° de latitud y longitud, con el objetivo de evaluar sus patrones de riqueza y sus similitudes florísticas. Los registros de presencia de las especies reportadas en la literatura para Guanajuato, se analizaron junto con las bases de datos en el Sistema Nacional de Información sobre Biodiversidad (SNIB), de la Comisión Nacional para el Conocimiento y Uso de la Biodiversidad (Conabio) y la del Instituto de Biología, de la Universidad Nacional Autónoma de México (UNAM). A partir de 29,897 registros únicos, se registraron 3,065 especies de plantas vasculares, distribuidas en 997 géneros, 187 familias y 54 órdenes. De ellas 1,174 especies son endémicas de México y 356 se consideran características del estado. Se determinaron 2 grupos florísticos (fitocorias) para el estado. Se discute cómo el conocimiento sobre la riqueza y el endemismo de una región o estado es fundamental para proponer regionalizaciones y estrategias para la conservación de la flora.

An updated checklist of the caddisflies from the State of Oaxaca, Mexico is presented, based primarily on a bibliographic review. Fourteen families, 44 genera and 216 species of caddisflies have been recorded, 38 (17.51%) of which are endemic, and 9 species are recorded for the first time from Oaxaca. For each species, we describe its geographic distribution, provide references with distribution records, and highlight those that are endemic to Oaxaca and Mexico. Although there has been a significant increase in taxonomic work on Mexican caddisflies, it is still necessary to continue studying the systematics, ecology, and biogeography of Trichoptera from Oaxaca, especially in poorly explored regions.

La diversidad fúngica de Colima, México ha sido escasamente estudiada con solo 80 especies de hongos macroscópicos no liquenizados y 2 especies de mixomicetos reportadas. La mayoría de los registros corresponden al siglo pasado y se han enfocado en las zonas templadas del estado. Se presenta un estudio de la diversidad de hongos macroscópicos y mixomicetos en Colima, México, con registros nuevos. Se llevaron a cabo muestreos en 8 localidades de 6 municipios, incluyendo zonas urbanas. Se adicionan 38 registros nuevos, de los cuales 5 pertenecen a Ascomycota, 21 a Basidiomycota y 12 a mixomicetos. Los géneros mejor representados en los muestreos fueron Geastrum (5 especies) y Didymium (3 especies). Geastrum chamelense e Itajahya galericulata corresponden al segundo y tercer registro nacional, respectivamente. Se aumenta a 106 el número de registros de especies de hongos y a 14 el de mixomicetos, dando un total de 120 taxones. Se sugiere realizar muestreos más extensos en zonas no exploradas, con énfasis en los grupos de hongos menos estudiados, tales como ascomicetos y basidiomicetos como hongos ramarioides, gasteroides y gelatinosos, así como cultivos en cámara húmeda para mixomicetos.

Migratory birds move geographically by tracking specific climatic conditions through time. However, we lack information about the climatic conditions birds are tracking, especially in intratropical migrants, whose movements are contained inside the tropics. The Yellow-green Vireo Vireo flavoviridis is an intratropical migrant whose migration patterns remain only partially documented and understood. Using GBIF presence records and WorldClim monthly climatic layers, we reconstructed ecological niche for Yellow-green Vireo’ reproductive and non-reproductive seasons. Then, we used a niche overlap analysis, based on a PCA-env approach and similarity tests, to assess overlap in climatic niches between seasons. We also projected climatic niches onto their spring and fall migration to evaluate the climatic conditions tracked by the species in transitional months. Overall, models revealed significant geographic inter-prediction between seasons. Similarity analyses showed high niche overlap between seasons; however, they failed to reject the null hypothesis of niche similarity. As expected by the hypothesis of niche conservatism in the tropics, Yellow-green Vireo is a niche follower. This information will help to clarify evolution of intratropical migration and provide ecological information for future conservation plans.

The tribe Miconieae was composed of a few genera, such as Miconia, Clidemia, Leandra, and Ossaea, but recent works have recognized Miconia as the only genus of the tribe. The morphological diversity of trichomes in Melastomataceae have been employed for systematic purposes, especially the foliar indumentum. In the present paper, hypanthium trichomes of 24 species of Miconieae were investigated, 8 species of Miconia sensu stricto and 16 species of Leandra, as a contribution to the taxonomy of the tribe. Samples were obtained from herbarium and plant specimens collected in a state park in Paraná, Brazil. The hypanthium indumentum of the samples was analyzed using a scanning electron microscope. Our results revealed that long-peduncle stellate trichomes appear only within Miconias.s., while dendritic eglandular trichomes and glandular trichomes appear only in Leandra. Mixed trichomes with a lateral gland are less frequent and were found in both genera. It is not surprising, therefore, that the hypanthia of the investigated species possess indumentum of potential taxonomic significance. The characters of the indumentum of Miconia s.s., and Leandra may be useful in the infrageneric taxonomy of the new proposal for the tribe Miconieae.

In the present study, we describe and illustrate Aplectana nananae n. sp. from the large intestine of Amphisbaena darwinii. Aplectana nananae n. sp. is the second species described in Argentinian amphisbaenian hosts and the 60th species assigned to the genus. This species differs from its congeners by a set of unique characters in males: the presence of 1 unpaired preanal papilla and gubernaculum, the papillae pattern (8+1:2:2) and total number (24+1), very conspicuous and prominent excretory pore, located anterior to the esophageal bulb and the size of spicules (60-70 μm).
在本研究中，我们描述和说明了来自达尔文两栖动物大肠的纳米Aplectana nananae n. sp。nananae Aplectana n. sp.是阿根廷两栖类宿主中发现的第二种，也是该属的第60种。该物种与其同属物种的不同之处在于其雄性具有一系列独特的特征:存在1个未配对的肛门前乳头和管状骨，乳头形态(8+1:2:2)和总数(24+1)，非常明显和突出的排泄孔，位于食管球前部，针状体大小(60-70 μm)。
