Resumen: Los bosques tropicales son sitios estructuralmente complejos, con una alta diversidad de especies de roedores, que incluyen especies terrestres y arborícolas. En las selvas secas de México, que mantienen una alta concentración de especies endémicas, se desconoce como usan diferentes tipos de hábitat en diferentes épocas del año. En este estudio evaluamos el uso de hábitat de los roedores arborícolas de la selva seca y selva mediana de la reserva de  la biosfera Chamela  Cuixmala en la costa central de Jalisco. El muestreo se realizó en dos temporadas y en los dos tipos de hábitat. Se utilizó la técnica de polvos fluorescentes para evaluar el uso de hábitat., que consiste en marcarlos con los polvos fluorescentes. Una vez capturados y marcados se realizó un seguimiento del rastro y se hizo un mapa del área recorrida. Se capturaron 149 individuos de cuatro especies de roedores y un marsupial obteniendo 136 rastros. Osgoodomys banderanus y Peromyscus perfulvus fueron las especies más abundantes.  En recorridos, las especies se desplazaron más veces en el suelo durante secas y en árboles tanto en secas como en lluvias. Se empleó una clasificación de los cuatro tipos de uso de hábitat, en secas, los roedores utilizaron el hábitat para buscar recursos, mientras que en lluvias, los roedores sólo buscaron refugio y escaparon de los depredadores. Las especies arborícolas presentaron uso diferencial del hábitat tanto por selvas como por temporadas y aprovecharon los recursos disponibles para poder sobrevivir dando una repartición de recursos y una selección espacial del hábitat para la coexistencia de las especies. Palabras clave: Uso de hábitat, polvos fluorescentes, roedores, Chamela, Jalisco. Abstract: The tropical dry forests are structurally complex sites that allow the establishment of a high diversity of species. We evaluated the habitat use of arboreal rodents in Chamela, Jalisco. The sampling was realized in two seasons and in both forests (the tropical semideciduous forest and the tropical dry forest). There was in use the fluorescent powders for the use of habitat, likewise there was realized a follow-up of the track and a map of the crossed area. I captured 149 individuals of Osgoodomys banderanus, Nyctomys sumichrasti, Peromyscus perfulvus and Xenomys nelsoni, obtaining 136 trails.  During dry season in tropical dry forest, there were more trails in the ground than in the trees and during the rainfall there were more trails in the trees than in the ground. In the tropical semideciduous forest the trails were the same, during two seasons in ground and trees. In dry season, the habitat use was the same and the rainfall season they searched refuges and escaped. In Chamela by its characteristic allowed that arboreal species presented differential use of the habitat both for forests and for seasons and took advantage of the available resources to be able to survive giving a distribution of resources and a spatial selection of the habitat for the coexistence of the species. Key words: Habitat use, fluorescent powders, rodents, Chamela, Jalisco.

Fauna in Tropical Dry Forest (TDF) is highly dependent on water availability due to a marked seasonality in precipitation. There are few studies addressing carnivore’s ecology and the role of seasonality of TDF in Neotropics. We used scent-station and camera trapping to assess seasonal changes in occurrence and habitat use probability with seasonality. We also described activity patterns and collected fresh scats to describe diet for small sized carnivore species in a TDF fragment in the Colombian Caribbean region. We present information regarding: Cerdocyon thous, Leopardus pardalis, and Procyon spp. The analysis showed a significantly higher occurrence probability during the dry season for the three species, and no differences in the detection probability between seasons. The diet of C. thous included 24 different food items; for L. pardalis it was composed of seven items, and finally, 25 food items were identified in the diet of Procyon spp. We found that the three species presented activity patterns corresponding with previous studies. Finally, our results reflect that these species are probably making more/larger habitat use during the dry season than in the wet season, because the area has permanent water ponds by which limited resources (such as water and food) are available almost constantly in this natural reserve.

Abstract Spondias tuberosa Arr., a fructiferous tree endemic to the northeast Brazilian tropical dry forest called Caatinga, accounts for numerous benefits for its ecosystem as well as for the dwellers of the Caatinga. The tree serves as feed for pollinators and dispersers as well as fodder for domestic ruminants, and is a source of additional income for local smallholders and their families. Despite its vantages, it is facing several man-made and natural threats, and it is suspected that S. tuberosa could become extinct. Literature review suggests that S. tuberosa suffers a reduced regeneration leading to population decrease. At this juncture S. tuberosa cannot be considered threatened according to the International Union for Conservation of Nature Red List Categories and Criteria, as it has not yet been assessed and hampered generative regeneration is not considered in the IUCN assessment. The combination of threats, however, may have already caused an extinction debt for S. tuberosa. Due to the observed decline in tree density, a thorough assessment of the S. tuberosa population is recommended, as well as a threat assessment throughout the entire Caatinga.
