RESUMENLos estudios sobre la mastofauna del estado de Campeche se remontan a principios de 1900, con los naturalistas que realizaron extensas expediciones y comenzaron a describir las especies de mamíferos para la Península de Yucatán. Para el estado de Campeche se han reportan 125 especies de mamíferos, de las cuales 110 son terrestres y 15 de afinidad acuática, representadas en 13 órdenes, 34 familias y 92 géneros. El orden con mayor riqueza de especies es Chiroptera, seguido de Rodentia y Carnivora. El nivel de endemismos es bajo para el Estado; sin embargo, existen 21 especies endémicas a Mesoamérica. Aproximadamente el 40% de las especies de mamíferos del Estado se encuentra amenazada y en peligro de extinción. Por ejemplo, la foca monje del Caribe (Monachus tropicalis) fue abundante en las costas de Campeche, pero se extinguió el siglo pasado. Campeche mantiene las coberturas de selva más extensas de México, con más de 2 millones de hectáreas protegidas. En especial la Reserva de la Biosfera Calakmul y las Reservas Estatales Balam-Kú y Balam-Kin mantienen buenas poblaciones de especies amenazadas como el jaguar (Panthera onca), pecarí de labios blancos (Pecari tajacu) y tapir (Tapirus bairdii). Esto lo hace un estado prioritario para la conservación de la diversidad biológica. Palabras clave: Campeche, conservación, endemismo, extinción, mamíferos, riqueza.ABSTRACTStudies of the mammals of Campeche date back to the early 1900s, when scientists began describing species for the Yucatan Peninsula. Presently, there has been reported 125 species of mammals, 110 of which are terrestrial and 15 marine ones. Those species represent 13 orders, 34 families, and 92 genera. Order with highest species richness is Chiroptera, Rodentia and Carnivora. The level of endemism is low for the state; however, there are 21 species endemic to Mesoamerica. Approximately 40% of the state’s mammal species are threatened with extinction. The Caribbean monk seal (Monachus tropicalis) was abundant on the coast of Campeche, but became extinct last century. Campeche maintains the most extensive tracts of forest of Mexico, with more than 2 million hectares protected. The Calakmul Biosphere Reserve and state reserves Balam-Ku and Balam-Kin maintain good populations of endangered species such as the jaguar (Panthera onca), white-lipped peccary (Pecari tajacu) and tapir (Tapirus bairdii). This makes the state a priority for the conservation of biodiversity. Key words: Campeche, conservation, endemic, extinction, mammals, richness species.

The state of Paraiba is one of those with the most degraded Caatinga that presents the large gap of knowledge concerning the mammal fauna. Mammals are among the taxa most affected by this. In this sense, we evaluated non-volant mammals’ richness and composition between March 2013 and February 2020 in a Caatinga fragment (121 ha). We used active search (336 hours) and camera traps (1,200 night traps). We recorded 20 species, including four threatened ones. Carnivora was the most representative order (7 species), followed by Rodentia (4 species). The richness of non-volant mammals found represents 35.6 % of the total number of such species in the Caatinga. This species richness is greater than that found in other studies in the state. The presence of these mammal species was mainly due to the recovering vegetation that resulted from the great planting effort and also due to cessation of hunt, cattle and sheep breeding that had existed on the farm for over thirty years. Our findings highlight the importance of this particular reserve due to the large number of species registered.

AbstractThe Río Plátano Biosphere Reserve (RPBR) represents the most important region in Honduras for conservation of the biodiversity of the country. From May 2017 to January 2019, we installed 24 camera traps in the RPBR to monitor big mammals, including Myrmecophaga tridactyla. In 1512 camera-trapping hours, the giant anteater was recorded in two photos. The photos presented herein of M. tridactyla are the first records of the species in the core of the RPBR. The protection of a vulnerable species such as M. tridactyla in the RPBR could also help to protect other species (Pecari tajacu, Tayassu pecari, Panthera onca) that are strongly threatened by illegal activities such as hunting, unauthorized access to the core zone, increased lands used for agriculture, and unsustainable exploitation of the natural resources.

Brazilian mammal fauna is considered to be the richest of the Neotropical region. However, in several regions of the country, there are gaps in the knowledge of its mammal fauna. Thus, we conducted a survey of the medium and large-sized mammal species in the fragmented Cerrado region in the southeast area of the state of Goiás. Nonlinear transects were conducted in 28 sessions over 13 months using direct observation methods, indirect observation methods (scratches, footprints, feces and lairs) and camera trapping. Twenty-five species belonging to eight orders were recorded. The species richness estimated by the Jackknife 1 method was 24.89 (±1.61) species in the transects and 16.88 (±1.29) species in camera trap, with stabilization of the species accumulation curves. Among the recorded species, 5 were endangered at the national level, and three were globally endangered. The high species richness found in the area in addition to the presence of endangered species highlights the need for conservation measures for the study site.

Landscape Degradation

Studies on diversity of animal communities allow determination of their species richness and composition.  This information is particularly relevant to establish sound conservation programs in biosphere reserves, where human activities should be focused on the sustainable use of natural resources and ensure biodiversity protection.  This study estimated the diversity and species richness and determined the species composition and activity patterns of medium- and large-sized terrestrial mammals in the Los Tuxtlas Biosphere Reserve (LTBR) located in Veracruz, Mexico.  We set 18 camera traps to record medium and large-sized terrestrial mammals from August 2016 to January 2017.  We calculated the trapping rate, guilds, and activity patterns of species.  Diversity was estimated with Hill numbers.  We compared our estimates with other studies in tropical forest in Mexico.  We obtained 308 independent captures of 13 species; Cuniculus paca and Dasyprocta mexicana were the species with the highest trapping rate.  Order-0, order-1, and order-2 diversity values were 13.99, 6.50, and 4.75 effective species, respectively, which ranks LTBR the fourth-most diverse reserve of medium- and large-sized terrestrial mammals compared to six other tropical rainforest sites in southern Mexico.  We recorded mammals representing five trophic guilds, of which frugivore-folivores (five species) and omnivores (three species) ranked highest.  All recorded species were primarily nocturnal (six species) or diurnal (six species).  Tamandua mexicana, Leopardus pardalis, L. wiedii, and Eira barbara are listed as endangered in the Mexican Official Standard Norm NOM-059-2019, and L. wiedii is listed as near threatened in the IUCN Red List of Threatened Species.  We were able to record 40.6 % of the terrestrial mammal species known to inhabit the LTBR.  The absence of large-sized species such as large predators and herbivores was notable.  Comparison of medium and large-sized mammal diversity of camera trapping studies in Mexico show that landscape degradation is impoverishing terrestrial mammal communities.

RESUMENEl oso hormiguero gigante también conocido en Centro América como oso caballo (Myrmecophaga tridactyla), es una de las especies carismáticas del mundo. Se ha documentado en la literatura que los límites de la distribución más septentrional para esta especie son Belice y Guatemala. El mapa de su distribución para Centro América da inicio en toda la franja Caribe de Panamá e incluye todo el territorio de Costa Rica, Nicaragua, Honduras, El Salvador y una mínima porción de la costa del Caribe de Guatemala y Belice. Sin embargo, M. tridactyla no se registra en los últimos 100 años para Guatemala, Belice y El Salvador. En Honduras se realizaron diferentes monitoreos en la región Caribe y Moskitia registrándose fotocapturas del oso caballo únicamente en la Reserva de la Biosfera del Río Plátano y la Reserva propuesta de Rus Rus. Este análisis propone como límite septentrional de la distribución del M. tridactyla la región de la Moskitia hondureña, basados en la ausencia de esta especie en los listados actuales oficiales de los países de Guatemala, El Salvador y Belice, en la revisión bibliográfica para Centro América  y en los monitoreos que se realizaron en la región Caribe y Moskitia hondureña. Palabras clave: Centro América, oso caballo, septentrional, Caribe, Moskitia.ABSTRACTThe giant anteater also known in Central America as oso caballo (Myrmecophaga. tridactyla), is one of the world’s charismatic species. It has been mentioned for different sources that giant anteater most northern limit distributions are Belize and Guatemala. The distribution map for Central America begins and extends throughout the Caribbean of Panama and includes the entire territory of Costa Rica, Nicaragua, Honduras, El Salvador and a minimal portion of the Caribbean coast of Guatemala and Belize. However M. tridactyla is not recorded in the last 100 years in Guatemala, Belize and El Salvador. In Honduras several biological monitoring were performed in the Caribbean and the Moskitia region recorded evidence for the specie only for the Biosphere Reserve of Río Plátano and the biological Reserve of Rus Rus in the Moskitia region. This analysis propose as most northerly for M. tridactyla the Honduran Moskitia region, based in the absence on the most recent check list for Guatemala, El Salvador, and Belize, also literature review for Central America and the biological monitoring performed in the Caribbean and Moskitia region. Keywords: Central America, giant anteater, Northern, Caribbean, Moskitia.

A utilização de novas metodologias em sala de aula é um assunto recorrente dentro das discussões sobre o ensino de geografia. Possuindo isso em mente, como produto da disciplina de Oficina em Geografia II da Universidade Estadual do Ceará (UECE) foi elaborado um material didático alternativo com objetivo de auxiliar os docentes na construção de um ensino contextualizado de Geografia. Essa pesquisa objetiva apresentar uma metodologia alternativa para o ensino de Geografia que visa praticar além da ação cognitiva de memorizar um conceito, trabalhando a interdisciplinaridade, a criatividade, o emocional e a cooperação. A proposta foi construir um RPG (Role Playing Game), que é um jogo que se utiliza da interpretação de personagens para criar e contar histórias coletivamente nas quais todos os agentes se tornam ativos dentro desse processo. Realizaram-se os seguintes procedimentos: revisão bibliográfica, seleção e adaptação do sistema de regras. Por fim, produziu-se a aventura de RPG intitulada “A busca pelo arco de Gelo”, que trabalha alguns aspectos físicos do nordeste brasileiro principalmente do estado do Ceará. Após a elaboração do material constatou-se a importância de trabalhar perspectivas para além do conteudismo. Sentiu-se a necessidade de aplicar no ensino básico para mensurar seu real impacto. Palavras-chave:  Recurso Didático. RPG. Geografia Física. ABSTRACTThe use of innovative methodologies in the classroom is a recurring subject in discussions about geography teaching. With that in mind, as a result of the discipline Workshop in Geography II from the State University of Ceará (UECE) was created, an alternative didactic material with the aid of teachers in the construction of a contextualized geography teaching. This research looks to show an alternative perspective for the teaching of geography that aims to practice beyond the cognitive action of memorizing the concept, but also working on interdisciplinary, creativity, the emotional and cooperation. The proposal was to build an RPG (Role Playing Game), which is a game that uses character interpretation to create and tell stories collectively in which all agents become active within that process. The following procedures were executed: bibliographic review, selection and adaptation of the rules system. At the end, it produced an adventure of RPG "The search for the arc of Ice" that works on physical aspects from the Brazilian northeast, focusing on the state of Ceará. After the material elaboration, it was clear the importance to work on perspectives beyond content. It felt the need to apply the didactic resource to measure its real impact.

Abstract This study presents a floristic-taxonomic treatment of Psidium in the state of Espírito Santo, and is a result of fieldwork combined with analyses of herbarium specimens. Fourteen species of the genus were recognized in Espírito Santo state (P. brownianum, P. cattleianum, P. cauliflorum, P. guajava, P. guineense, P. longipetiolatum, P. myrtoides, P. oblongatum, P. oligospermum, P. ovale, P. rhombeum, P. rufum P. sartorianum, and Psidium sp.), accounting for about 34% of the species richness estimated for the genus in the Atlantic Rainforest biome. The species occur predominantly in lowland forests up to 700 meters above sea level. These areas are highly threatened due to urbanization of coastal areas and agricultural expansion in the state Espírito Santo. Therefore, the conservation of Psidium species in this state requires the creation of more lowland protected areas.
