ResumenDe las seis especies de felinos silvestres que habitan en México, es del margay o tigrillo (Leopardus wiedii) una de las que menos información se tiene. En Nayarit no se cuenta con información detallada de su distribución a nivel estatal, encontrando únicamente dos registros para esta especie. Como parte de un muestreo piloto utilizando cámaras trampa en el parque natural La Montaña Encantada, Municipio de Xalisco, Nayarit, se obtuvieron cuatro registros de margay. Una fotografía se tomó en un arroyo en una selva mediana subcaducifolia, mientras que los tres restantes se obtuvieron en un camino de terracería de un bosque de latifoliadas, camino que también fue utilizado por personas a pie y en vehículo. Tres de las cuatro imágenes corresponden al mismo individuo, mientras que la cuarta no pudo ser identificada por ser del costado izquierdo del organismo. Además por la pérdida del hábitat natural, se detectaron gatos y perros ferales, lo que representa un peligro para la permanencia de esta especie en la zona. Los registros del presente trabajo confirman la presencia del margay en el estado y constituye el primer registro para el municipio de Xalisco, ampliando su distribución conocida 83.7 km suroeste y 43.7 km sureste de los registros previos.Palabras clave: carnívoros, felinos, Nayarit, margay.AbstractOf the six species of wild cats that inhabit Mexico, it is the margay or tigrillo (Leopardus wiedii) one of the least information available. In Nayarit, there is no information on its distribution at the state level with only two records for this species. As part of a pilot study in La Montaña Encantada natural park, municipality of Xalisco, Nayarit, four records of margay were obtained. One photograph was obtained in a dry stream surrounded by tropical deciduous forest, while the other three were taken on a dirt road from an oak forest. This road was also used by people on foot and by vehicle. Three of the four images corresponded to the same individual, while the fourth could not be identified because the picture shows the left side of the organism. In addition to the loss of natural habitat, feral cats and dogs were detected, which represents a danger for the permanence of this species in the area. The records of this work confirm the presence of the margay in the state, represents the first record for the Municipality of Xalisco, and extend its known distribution 83.7 km to the southwest and 43.7 km to the southeast of the previous records.Key words: carnivores, felines, Nayarit, margay.

 Resumen: Se examinaron 568 ejemplares de mamíferos nativos de 49 especies, procedentes de 49 localidades de la Meseta Tarasca o Sierra Purépecha del Estado de Michoacán, México. Las especies encontradas en esta región del Eje Volcánico Transversal incluyen 1 marsupial, 2 insectívoros, 17 quirópteros, 2 carnívoros, 24 roedores y 1 lagomorfo. Para calcular la diversidad de especies en los cuatro hábitats muestreados, se utilizaron las 2 especies de insectívoros y 21 de roedores. De mayor a menor diversidad, en el bosque de pino-encino se recolectaron 201 individuos de 15 especies (H’ = 2.49), en el bosque tropical caducifolio 142 de 15 especies (H’ = 2.43), en el bosque de oyamel 92 individuos de 10 especies (H’ = 2.01) y en las áreas de ecotono 52 individuos de cuatro especies (H’ = 1.15). El registro de Hylonycteris underwoodi es el primero para las partes altas del Estado de Michoacán. Abstract: We examined 568 specimens of native mammals belonging to 47 species from 49 localities of the Tarascan Plateau or Sierra Purépecha mountain range in the State of Michoacán, México. Species composition of this enclave in the Transvolcanic Belt is 1 marsupial, 2 insectivores, 17 bats, 2 carnivores, 24 rodents, and 1 lagomorph. To calculate the species diversity according to the four sampled habitats, only the 2 insectivore and 21 rodent species were included. From higher to lower diversity values, we found 201 specimens from 15 species in pine-oak forest (H’ = 2.49), 142 from 15 species in tropical deciduous forest (H’ = 2.43), 92 specimens belonging to 10 species fir forest (H’ = 2.01), and 52 from four species in an ecotonal area (H’ =1.15). Hylonycteris underwoodi is the first record for the highlands from the State of Michoacan. Key words: Mammals, distribution, diversity, Tarascan Plateau, Michoacán.

Geologic History

Based on the review of floristic and taxonomic literature, as well as on the examination of specimens housed at the herbaria of the Centro Regional del Bajío (IEB) and the Instituto de Biología (MEXU), we recorded 845 species, 352 genera and 100 families of trees for the state of Michoacán, Mexico. The largest numbers of species per family were recorded for Asteraceae (82), Fabaceae (74), Mimosaceae (67), Caesalpiniaceae (39) and Burseraceae (38), while at the genus level Bursera (37), Quercus (35), Lonchocarpus (19), Senna (18), and Acacia (16) are the most speciose. The genus Beiselia (Burseraceae) and 14 species (1.8 %) are strict endemics to the state. A total of 28 families (28%) and 210 genera (60%) are represented in the state only by one tree species each. The most important vegetation types according to their species richness are tropical deciduous forest (593, 70.2%), coniferous forest (336, 39.8%) and oak forest (332, 39.3%). A high proportion (69.9%) of Michoacán’s tree species is located in 2-4 vegetation types; 173 species (21.5%) have been found just in one type, mainly in the tropical dry forest (87 species, 10.3%). The floristic richness of Michoacán is largely explained by its complex geologic history, its rugged physiography, its diverse climate, and its multiple vegetation types, as well as by its location at the confluence of the Holartic and Neotropical floristic kingdoms. Counties and species on which to focus conservation efforts for trees in the state are pinponted.

Neurosystasis Satchell is newly recorded in Mexico by means of the description of a new species. Specimens captured in a tropical deciduous forest in southern Puebla, central Mexico, were examined and determined as a species new to science. The male and female are described based on morphological characteristics. Neurosystasis longistylis sp. nov. is similar in appearance to Neurosystasis saltenia (Omad, Mangudo & Gleiser, 2015), but is readily distinguished based on characters of the head, wing, and male genitalia. In both species, R2+3 is attached to vein R4, the wing membrane is infuscate with dark spots on vein apices, and lacks sensory organs near the apex of Sc, characters not present in other species of Neurosystasis, and for that reasons we proposed the recovery of Chuspilepia from its synonym and validate it as a subgenus of Neurosystasis to include both continental species.

Eleven Species

Otatea, with 12 described species, is the second most diverse genus in the subtribe Guaduinae. Eleven species of Otatea occur in Mexico, of which 10 are endemic. The Mexican Otatea species grow in tropical dry forest, the ecotone between tropical dry forest and oak forest, cloud forest, humid oak-pine forest, and xerophilous scrubs. Here, we describe the synflorescence and flowers of Otatea nayeeri and O. transvolcanica, based on newly collected specimens and review of existing herbarium material. We present a key based on the flowering characters of the Mexican Otatea species, and provide expanded morphological descriptions and illustrations of O. nayeeri and O. transvolcanica. Otatea nayeeri and O. transvolcanica do not exhibit the gregarious monocarpic flowering pattern that has been recorded for other Otatea species. A flowering individual of O. transvolcanica was observed being visited by a Lasioglossum (Dialictus) sp. (Halictidae) bee. This is the first record for Otatea being visited by bees. The geographical distribution of O. nayeeri is extended northwards to the state of Durango in Mexico.

A taxonomic and nomenclatural review of the genus Croton (Euphorbiaceae) in the Mexican state of Michoacán is presented. Six sections and 20 species are here reported. The greatest diversity is in the Balsas Depression province, where at least 12 species occur. There is a strong tendency to thrive in tropical deciduous forest. An identification key is provided, and for each species, the following information is included: protologue citation, type information, habit, habitat, and elevation within the state, regional and global distribution, and phenology. Relevant synonyms are listed, as too are herbarium specimens. Lectotypes are designated for Croton draco, C. niveus, and C. calvescens. One species, Croton rojasii, is described as new and illustrated with photos. It is known only from tropical deciduous forest in the Zicuirán-Infiernillo Biosphere Reserve, at elevations from 400 to 700 m. It belongs to sect. Geiseleria and is remarkable because of the strongly unequal pistillate sepals, the larger of which becoming accrescent and exceeding the fruit.

Important Species

The leafhopper Poekilloptera phalaenoides L. (Auchenorrhyncha: Flatidae) is a very important species in agriculture because it causes damages and economic losses in agricultural activities. In observing fragments of semi-deciduous forest, riparian forest and cerrado forest (Cerradão) in Jataí, Montividiu and Paraúna in the southwest of the state of Goiás during the month of January 2012, were observed natural populations of Tachigali vulgaris (carvoeiro-branco). In the southwest of Goiás, an important agricultural region of the country, little is known about the damage caused to commercial crops by the leafhopper treated in this work, but here we call attention to the action of an agricultural pest interacting negatively with the native vegetation. The presence of P. phalaenoides in the Cerrado is already known, but the presence of the spittlebug in the southwest of the state of Goiás in T. vulgaris, especially in a situation of damage to the native population of the tree in forest fragments surrounded by agricultural crops. Thus, the objective of this work is to bring this first record of P. phalaenoides in T. vulgaris in the Cerrado of southwestern goiano.

Dactylorhiza fuchsii (Druce) Soó is a terrestrial orchid belonging to the family Orchidaceae and listed in the Red Book of Kazakhstan, the Baltic region, and the most regions of Russia. D. fuchsii is an interesting object for research in many countries of the world and the study of its biological features and coenotic significance, as well as its distribution and conservation in nature is still relevant today. The article analyzes the most significant biological and coenotic features of D. fuchsii: distribution of the species; features of the structure and dynamics of coenopopulations in different regions; ontogeny; cultivation in Botanical gardens; features of reproduction, including using the method of tissue culture, etc. It reflects the main places of growth in Kazakhstan and the principles of conservation in connection with the classification of the species as rare, subject to protection at the state level. Indicators of D. fuchsii participation in plant communities have been identified on the example of forests of the State National Natural Park “Burabay” (Northern Kazakhstan).

Interspecific interactions among tropical mesocarnivorous species and other mammalian trophic guilds have been poorly studied, despite they have important implications in the survival, structure, demography, and distribution of these species. In this study we analyzed spatio-temporal interactions of three sympatric mesocarnivores that are located in the Northeastern limit of their geographic distribution in Mexico, with the objective of analyzing if these species coexist or compete in the axis of the temporal and spatial niche. With a sampling period from January 2015 to December 2016 and 26 camera-trapping stations (with in a set of two camera traps opposite to each other) and located along roads and animal trails, we determined the activity pattern and habitat use of L. wiedii (margay), L. pardalis (ocelote) y P. yagouaroundi (yaguarundi). All independent photographs of each species were grouped into three temporal categories (day, night and twilight) and six habitat categories; Oak Forest, Oak-Pine Forest, Cloud Forest, Pine-Oak Forest, Tropical Deciduous Forest and Medium Forest. Temporal and spatial overlap between species (i.e interactions) was obtained with the Czekanowski index and the Pianka index, respectively. These indices are symmetrical and take values from zero to one, where the results close to zero indicate that there is no overlap between species and values close to one indicate overlap. We obtained a total of 379 independent photographs, of which 239 corresponded to margay, 118 to ocelot and 22 to yaguarundi. Margay and ocelot were nocturnal, with 75 % of their records in this category showing a high temporal overlap (0.85); whereas yaguarundi was fully diurnal, suggesting it may be able to coexist with the other two species (margay and ocelot). Moreover, the yaguarundi used habitat similar to ocelot and margay (with high spatial overlap of 0.81 and 0.72, respectively), while the spatial overlap between the margay and ocelot was intermediate (0.53), since they used in most cases different habitat types. Our results suggest that there is no interspecific competition among these tropical mesocarnivorous species, probably due to antagonistic interactions among them on the temporal and spatial axis. These strategies may positively favor populations of mesocarnivores, which are characterized by having a high territorial behavior.
