Los bosques de montaña de Los Altos de Chiapas se han fragmentado y han modificado su estructura y composición florística debido a la tala, la agricultura y el crecimiento urbano. Una alternativa que se ha promovido para su conservación es el ecoturismo. El objetivo fue diagnosticar la efectividad del manejo ecoturístico en la conservación de los bosques de montaña de los Parques Ecoturísticos Arcotete, Grutas de Mamut y Grutas de Rancho Nuevo del municipio de San Cristóbal de Las Casas. Se registraron variables de estructura vertical, horizontal y de uso del bosque en parcelas de 1,000 m2. Se calcularon índices de diversidad de números de Hill y un índice de condición ecológica por parcela a través de un modelo determinístico. Se procesaron imágenes de satélite de los años 2005, 2011, 2015, 2021 para obtener cambios en los usos de suelo. Arcotete y Grutas de Mamut tuvieron un índice de condición ecológica del bosque de 0.5 y Grutas de Rancho Nuevo de 0.3, lo que indica que los 2 primeros tienen un estado de conservación intermedio. Se concluye que el ecoturismo permitió el incremento en la cobertura forestal, que se traduce en una condición ecológica baja y moderada.
由于伐木、农业和城市发展，恰帕斯高地的山地森林已经支离破碎，并改变了其结构和植物区系组成。另一种选择是生态旅游。本研究的目的是评估生态旅游管理对San cristobal de Las Casas市Arcotete生态旅游公园、Mamut洞穴和Rancho Nuevo洞穴山地森林保护的有效性。本研究的目的是评估墨西哥中部和南部地区的森林利用情况。本研究的目的是评估在墨西哥恰帕斯州和恰帕斯州的两个不同地点，以及在墨西哥恰帕斯州、恰帕斯州和恰帕斯州的两个不同地点，在恰帕斯州和恰帕斯州的不同地点，在恰帕斯州和恰帕斯州的不同地点。对2005年、2011年、2015年和2021年的卫星图像进行了处理，以获得土地利用的变化。森林生态状况指数为0.5，牧场新洞穴生态状况指数为0.3，表明前2个洞穴处于中等保护状态。该研究的目的是确定生态旅游对森林覆盖率的影响，并确定生态旅游对森林覆盖率的影响。

We assessed the efficiency of camera trapping in monitoring bird and mammal species in the grasslands of Tandilia Mountains by calculating the naïve occupancy, capture rate, and time to the first detection for each species. We compared the observed richness with the reported richness from online databases. We performed species accumulation curves to estimate the sampling effort necessary to detect bird species. We detected 50 bird and 15 mammal species. The top 5 bird species (Chalk-browed Mockingbird, Rufous-collared Sparrow, Rufous Hornero, Great Pampa-Finch, and Spotted Nothura) accounted for 48% of all detected individual birds, with naïve occupancy of 21-25% and mean times for the first detection between 6 and 9 days. The top 5 mammal species (Pampas fox, Large hairy Armadillo, European hare, Molina’s hog-nosed skunk, and Geoffroy’s cat) accounted for 81% of all detected individual mammals, with naïve occupancy of 32-77% and mean times for the first detection between 4 and 7 days. A sampling effort of 2 weeks was the optimal balance between effort and result qualities. We detected all the reported richness of mammals and half of the reported grassland-associated birds. We provide valuable information for future grassland species monitoring with camera trapping in Neotropical grasslands.

Los estudios poblacionales de mariposas en el Caribe colombiano son escasos, razón por la cual se analizó la estructura poblacional y el desplazamiento de Hamadryas Hübner (1806) en diferentes usos del suelo en un paisaje fragmentado en los Montes de María, San Jacinto, Bolívar. Se realizaron 6 muestreos entre marzo y junio de 2018. En el área de estudio se ubicaron 7 estaciones donde se colocaron 5 trampas Van Someren-Rydon cebadas con mezcla de fruta fermentada. Mediante el método de captura-marcaje-recaptura, se registraron 541 individuos del género Hamadryas (312 machos - 229 hembras). La especie más abundante fue H. feronia (Linnaeus, 1758) con 291 individuos registrados y la menos frecuente H. amphinome (Linnaeus, 1767) con 33 registros. Las proporciones sexuales variaron, aunque el número de machos siempre fue mayor y las hembras experimentaron una mayor distancia de desplazamiento. La estructura de edades y las recapturas mostraron un pico de emergencia de imagos entre abril-junio. Por último, la variación de la abundancia de Hamadryas se asocia, principalmente, con la cobertura del dosel, indicando que este factor juega un papel determinante en la dinámica poblacional de este grupo de mariposas.
对哥伦比亚加勒比地区蝴蝶种群的研究很少，这就是为什么我们分析了Hamadryas hubner(1806)在不同土地用途下的种群结构和迁移，在Montes de maria, San Jacinto, bolivar。2018年3月至6月共进行了6次抽样。在研究区域设置了7个站，其中放置了5个Van Someren-Rydon诱捕器，这些诱捕器是用发酵水果混合的大麦制成的。采用捕获-标记-再捕获法，共记录Hamadryas属541只(公312只，母229只)。最丰富的种是H. feronia (Linnaeus, 1758)，有291个记录，最不常见的H. amphinome (Linnaeus, 1767)，有33个记录。性别比例各不相同，但雄性的数量总是更多，雌性的移动距离也更大。年龄结构和再摄取显示4 - 6月图像出现高峰。最后，Hamadryas丰度的变化主要与冠层覆盖有关，表明这一因素在这一群体的种群动态中起着决定性的作用。

La restauración activa y la restauración pasiva son estrategias utilizadas para recuperar paisajes forestales. Pocos estudios han evaluado la recuperación de la fauna comparando diferentes estrategias de restauración de la misma edad en un paisaje tropical. En este estudio comparamos la abundancia y la frecuencia de presencia de los escarabajos carroñeros Nicrophorus olidus y Oxelytrum discicolle, entre un bosque en restauración pasiva de 23 años (RP), un bosque en restauración activa de 23 años (RA), un pastizal ganadero y un bosque de niebla. Analizamos cómo varían las poblaciones de los escarabajos entre temporadas climáticas y examinamos la relación de 10 variables del hábitat con la respuesta de los escarabajos. Nicrophorus olidus fue más abundante en RA y O. discicolle en RP. La abundancia de ambas especies varió entre temporadas. La respuesta de N. olidus a la restauración estuvo relacionada con las coberturas del dosel y del helecho Pteridium arachnoideum. La abundancia de O. discicolle no estuvo relacionada con ninguna variable. Cada estrategia de restauración ofrece condiciones ambientales que influyen de manera diferencial en las especies, aun cuando pertenecen al mismo gremio. Destacamos la importancia de restaurar paisajes con estrategias complementarias que contribuyan a recuperar poblaciones de distintas especies.

Three main genetic diversity hotspots were identified in a survey of the genetic variability of the populations of the candy barrel cactus Echinocactus platyacanthus, a protected and highly sought-after cacti for ornamental, culinary and livestock water source in the Chihuahuan Desert Region, Mexico. This study identified one southern, one central, and one northern population in the Chihuahuan Desert Region as first priorities for conservation based on the analysis of a matrix of 4 ISSRs for 183 individuals from 10 localities along the 900 × 300 air km polygon of the geographic distribution of the species. The genetic structure of the 183 individuals from the 10 populations studied, showed a high degree of genetic differentiation for each of the localities with low gene flow, making each of these populations important for conservation actions. The isolation by distance analysis showed that other factors apart from the geographic distance could be playing an important role in the differentiation of the genetic structure of the populations. The UPGMA tree derived from the genetic distance matrix showed that the central and the southern populations conform a mega genetic population clearly separated from the northern populations, each with its own genetic signature.

The Sierra Gorda de Querétaro Biosphere Reserve (SGQBR) is one of the largest natural protected areas in Mexico; however, little is known about the richness and diversity of amphibians and reptiles. We present an updated list of species of both groups, the conservation status of these species, as well as an analysis of their diversity with respect to other protected natural areas (NPAs) in central Mexico. The SGQBR contains 132 herpetofauna species (35 amphibians and 97 reptiles). The richest and most diverse families for amphibians were Hylidae (anurans) and Plethodontidae (caudates), and for reptiles Phrynosomatidae (lizards), Colubridae and Dipsadidae (snakes). The values of taxonomic diversity of the SGQBR were similar to those for the regional pool considering others NPAs. However, it did not achieve the highest values compared to the adjacent Los Mármoles National Park or Sierra Gorda de Guanajuato Biosphere Reserve. There was a high complementarity in the species composition between El Chico National Park and SGQBR for both herpetofauna groups. Although a formal list is presented, it is necessary to carry out a greater number of studies focused on analyzing diversity, considering functional attributes of the species and the richness by vegetation types.
塞拉戈达德奎尔梅塔罗生物圈保护区(SGQBR)是墨西哥最大的自然保护区之一;然而，人们对两栖动物和爬行动物的丰富性和多样性知之甚少。本文对这两个类群的物种进行了更新，并分析了它们在墨西哥中部其他自然保护区(NPAs)的多样性。SGQBR包含132种爬行动物(35种两栖动物和97种爬行动物)。最丰富和最多样化的两栖动物科是水螅科(无尾目动物)和齿齿科(尾类动物)，爬行动物科(蜥蜴)、蛇科和蛇科(蛇)。考虑到其他保护区，SGQBR的分类多样性值与区域池相似。然而，与邻近的Los Mármoles国家公园或Sierra Gorda de Guanajuato生物圈保护区相比，它没有达到最高的价值。El Chico National Park和SGQBR在物种组成上具有高度的互补性。虽然已经有了一个正式的名录，但在考虑物种功能属性和植被类型丰富度的基础上，还需要开展更多的多样性分析研究。

The ecological network approach allows the analysis of interactions between plant communities and their floral visitors. However, most floral visitation network studies analyze the interactions with a temporally-static perspective. Hence, few studies have evaluated the temporal variation of these systems. This study characterized the plant-floral visitor interaction network of a temperate forest remnant in Michoacán, analyzing monthly changes in its composition, structure, and dynamics during 3 seasons of the year. In total, we recorded 1,325 floral visits and 131 links between 27 plant species and 74 floral visitor species. Most of the plant species observed belong to the families Lamiaceae, Asteraceae, and Apiaceae, while most of the floral visitor species observed belong to the orders Hymenoptera, Lepidoptera, and Diptera. Most of the floral visits were recorded in highly abundant plant species with longer flowering periods at the study site. The constant species turnover gave rise to monthly plant-floral visitor networks with different levels of specialization, connectance, nestedness, and modularity. Our results suggest that plant-floral visitor networks in temperate forest remnants are highly dynamic and poorly connected, which makes them vulnerable to drastic changes in the environment.

Most of the floral visits were recorded in highly abundant plant species with longer flowering periods at the study site. The constant species turnover gave rise to monthly plant-floral visitor networks with different levels of specialization, connectance, nestedness, and modularity. Our results suggest that plant-floral visitor networks in temperate forest remnants are highly dynamic and poorly connected, which makes them vulnerable to drastic changes in the environment.","PeriodicalId":49603,"journal":{"name":"Revista Mexicana de Biodiversidad","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135739626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We carried out a taxonomic revision of the Stenopelmatus talpa species group (Stenopelmatidae: Stenopelmatini), a poorly studied group of orthopterans whose species are distributed along the Trans-Mexican Volcanic Belt and adjacent areas of the Sierra Madre Oriental and Sierra Madre del Sur in Central Mexico. We examined both features from both the external morphological and male internal genitalia, and also carried out a molecular species delimitation based on DNA barcoding. An integrative approach based on congruence of morphological and molecular evidence helped to delimit 9 species for the S. talpa species group, 7 of which are new to science whereas the remaining 2 are already described, S. talpa and S. typhlops. We described 4 out of the above 7 new species: Stenopelmatus chilango sp. nov., S. purepecha sp. nov., S. sierragordaensis sp. nov. and S. tlaxcalli sp. nov. A key to the described species of the S. talpa species group is provided. Our study highlights the relevance of the male internal genitalia as a valuable character system to delimit species in Stenopelmatus.

The taxonomy of abyssal polychaetes is problematic because they are fragile and easily damaged during collection. Ilyphagus Chamberlin, 1919 is an abyssal flabelligerid annelid genus that includes 4 species; a new species from the Eastern Pacific is herein described: I. gebruki n. sp. This new species is diagnosed as having a cigar-shaped body, more than 5 times longer than wide, with long body papillae, branchial plate with 8 branchial filaments, notochaetae with articles progressively longer, and neurochaetae smooth. The species ranges from off the Aleutian Islands to the Peru-Chile Trench and was sampled in sediments distributed between 5,047 and 7,000 m depth.
