Study Sites

For an inter-seasonal 4-month period, we recorded the parts of plant species consumed by a troop of 16 spider monkeys (Ateles geoffroyi) in three forest fragments in the western wetland of the Yucatan Peninsula. In these forest fragments, spider monkeys ate vegetal parts of five plant species: leaves and fruits of fig (Ficus maxima) and zapote (Manilkara zapota), leaves and flowers of white mangrove (Laguncularia racemosa), leaves of huano palm (Sabal yapa), and fruits of chechem (Metopium brownei). With exception of the latter, plant species consumed by spider monkeys in the forest fragments studied, constitute the most important forest resources in the regional wetland. Consumption of vegetal parts from white mangrove in our study sites represents the first record of this plant species in the diet of spider monkey within the Neotropics.

Abstract The spider monkey, a fruit specialist and important seed dispersal agent in the Neotropics, is an endangered primate due to habitat loss, hunting and the pet trade. Spider monkeys have been the subject of a few studies in Central and South America, but little is known about the diet and ranging for this primate in southern Mexico. Here we report the results of a six-month long study (October 2010 to March 2011) of the feeding preferences and ranging patterns of the Yucatan spider monkey Ateles geoffroyi yucatanensis living in the “Ya´ax´che” reserve by the Caribbean coast in northeast Yucatan peninsula. Focal animal and scan sampling as well as GPS tracking were used to document spider monkey feeding behavior, location of food trees and ranging in the reserve. The spider monkeys used 36 species of plants (94% trees; n = 432) and six non tree morphospecies as a source of food. Six tree species accounted for ≥80% of total feeding time and for 74% of all trees used. Fruits accounted for 59% of total feeding time, followed by leaves (35%), palm piths (5%) and other plant parts (1%). Total range used by the monkeys was estimated at 43% of semievergreen rainforest habitat available (ca 40ha). Range use was not random with segments showing light, moderate and heavy use; the use of different areas of their range varied monthly and was closely linked to the spatial dispersion of the trees used for food.

Subsequent Separation

In September, 1930, Dr E. C. Faust brought back from the Coto Region of Northern Panama two young female spider monkeys (Ateles geoffroyi). On December 11th one of these died from an experimental infection of Strongyloides stercoralis, and at autopsy was found to be very heavily infested with lice. Previous to this date the monkey had been handled a number of times but no lice noticed, although the two monkeys had frequently been observed carefully examining each other for external parasites. It is believed that the subsequent separation of the two (November 22nd) combined with the victim's illness allowed the lice to multiply at a prodigious rate. The hairs practically all over the body were found to bear nits, frequently as many as three or four per hair. Only a few lice have ever been found on the other monkey in spite of several careful examinations.

Genomic Study

The large-insert genomic DNA library is a critical resource for genome-wide genetic dissection of target species. We constructed a high-redundancy bacterial artificial chromosome (BAC) library of a New World monkey species, the black-handed spider monkey (Ateles geoffroyi). A total of 193 152 BAC clones were generated in this library. The average insert size of the BAC clones was estimated to be 184.6 kb with the small inserts (50-100 kb) accounting for less than 3% and the non-recombinant clones only 1.2%. Assuming a similar genome size with humans, the spider monkey BAC library has about 11× genome coverage. In addition, by end sequencing of randomly selected BAC clones, we generated 367 sequence tags for the library. When blasted against human genome, they showed a good correlation between the number of hit clones and the size of the chromosomes, an indication of unbiased chromosomal distribution of the library. This black-handed spider monkey BAC library would serve as a valuable resource in comparative genomic study and large-scale genome sequencing of nonhuman primates.Key words: black-handed spider monkeys, Ateles geoffroyi, BAC library.

Photosynthetic efficiency was estimated by chlorophyll fluorescence measurements (Fv/Fm) in 11 plant species growing along a steep gradient of airborne pollution along the Russian-Norwegian border (70°N, 30°E). Photosynthetic efficiency was positively correlated with environmental variables including annual temperature and a maritime gradient and was negatively correlated with the airborne concentrations of Cu, Ni, and SO2 from the Cu-Ni smelters. Photosynthetic efficiency in six plant species from the mixed forest, but not pine (Pinus sylvestris L.), and three species from the birch forest was inversely correlated with SO2 and the concentrations of Ni and Cu in lichens. Measurement of fluorescence in these species was a sensitive indicator of pollutant impact. Plant cover at the 16 study sites and the photosynthetic efficiency of five target species correlated with normalized difference vegetation index (NDVI) values. This study demonstrated that it is possible to detect relations among field-measured ecophysiological responses in plants, levels of airborne pollutants, and satellite remote-sensed data.Key words: chlorophyll fluorescence, smelters, sulfur dioxide, nickel, copper, normalized difference vegetation index (NDVI).

First Time

The first record for South Italy of Cymbalophora rivularis (Ménétriès, 1832) is reported, until now recorded in Italy only for Central Apennine. Three specimens were collected during August-September 2017, in an Acer spp. forest located on Monte Sparviere, a Site of Community Importance within the Pollino National Park. Furthermore, this species was successfully barcoded for the first time. This finding reinforces the biogeographic importance of Pollino Massif as refuge area for relict populations of several animal and plant species.
