Abstract: The geographical position of Costa Rica has historically played an important role in the composition and diversity of our mammalian fauna, consisting of species originating both in the Neartic and Neotropical regions. Based on published data, new descriptions and reports, we here present an updated list of all terrestrial and aquatic Costa Rican mammals. We summarize available information on their status, and present our concerns regarding those species with populations under alarming conditions. The mammalian fauna of Costa Rica is mainly Neotropical. A total of 238 species, grouped

Abstract:

Lantana camaraL. (Verbenaceae) is a shrub of Neotropical origin that has spread to at least 60 countries (Dayet al. 2003), and its ability to rapidly occupy disturbed habitat has led to it being named one of the ten worst weeds on the planet (Cronk & Fuller 1995, Sharmaet al. 2005). A number of traits may have contributed to its success as an invasive species. For example,L. camaraincreases the available soil nitrogen in otherwise nitrogen-poor ecosystems (Sharma & Raghubanshi 2009), it is extremely resilient to disturbance (Gentle & Guggin 1997a, Hiremath & Sundram 2005), it i

Abstract:

Habitat loss and increases in habitat isolation are causing animal population reductions and extirpations in forested areas of the world. This problem extends to protected areas, which, while often well-conserved, can be too small and isolated to maintain species that exist at low densities and require large contiguous areas of habitat (e.g. some large mammals). Costa Rica has been at the forefront of tropical forest conservation and a large proportion of the country’s land area is currently under some form of protection. One such area is the northwest portion of Costa Rica, which is an extrem

Despite probable undercounts of squirrel monkeys within sites and potentially missed localities, the total population size should be considered far below a size that would provide longterm genetic viability.

Abstract:

There is very little information on the biogeochemical ecology of Sphagnum species in tropical regions. The majority of the ecological information on Sphagnum species in the tropics consists of general habitat information and pH values that are reported in new species descriptions and regional floras such as those of Crum (1980, 1989), Crum and Buck (1988), Karlin (1991), and McQueen (1989).

AbstractThis article gives the first results of a study of dorylaims found in nature reserves in Costa Rica. The material examined shows the great interest of the nematofauna of these reserves. Two species were found for which new generic names had to be erected: Parapalus n.gen. for a species resembling Paraxonchium but with a long symmetrical odontostyle as in Gopalus; the single species P.arboricola n.sp. lives in epiphytic mosses. Inbionema n.gen. is conspicuous for the very widely separate lips and the long (but not needle-shaped) odontostyle; the single species I. biforme n.sp. (named be

Abstract:

Three new species of Cumacea are described from Costa Rican coastal waters. The bodotriids, Cyclaspys breedyae n. sp. and Cyclaspis vargasae n. sp., occurred on the Pacific coast, and the nannastacid, Cumella spinifera n. sp., came from a shallow back reef habitat of the Caribbean coast. Cyclaspis breedyae n. sp., which was collected from shallow water (1 1.5 m) at a beach just north of Puerto Caldera, has affinities with Cyclaspis varians Calman, 1912 from the northwestern Atlantic; it differs by having a carapace with fewer (usually 4), but larger, dorsal spines behind the ocular lobe and by

AbstractEven though Arabica coffee (Coffea arabica Linnaeus, Rubiaceae) can self-pollinate, bees are important pollinators, without which there is lower fruit quality and yield. We studied bee diversity in coffee agroecosystems in Costa Rica during two coffee flowering seasons (2005 and 2006). Malaise traps were used as a passive sampling method to collect bees during coffee blooms. We collected 1012 bee individuals from three different site types: nonagricultural fields and shaded and unshaded coffee farms. Unshaded coffee farms had significantly higher species richness (S) and number of bee

Abstract:

Degraded and secondary forests comprise approximately 50% of remaining tropical forest. Bird community characteristics and population trends in secondary forests are infrequently studied, but secondary forest may serve as a “safety net” for tropical biodiversity. Less understood is the occurrence of time-delayed, community-level dynamics such as an extinction debt of specialist species or a species credit resulting from the recolonization of forest patches by extirpated species. We sought to elucidate patterns and magnitudes of temporal change in avian communities in secondary forest patches i

Abstract:

A new species of Cupania, endemic to Costa Rica, is described and illustrated. The species is similar to C. largifolia, but it differs by having vinaceous young leaves, the longest petioles more than 8 cm long, trilobed capsules, each lobe obtuse, dorsally costate, epicarp greenish-yellow, densely puberulent, rugose, and endocarp tomentulose. Notes on its distribution, habitat, phenology, conservation assessment, etymology, and discussion on taxa with similar morphology are provided.

Abstract:

A checklist of the marine and estuarine fishes of the inner part of the Gulf of Nicoya, Pacific coast of Costa Rica, Central America, was compiled by examining a museum fish collection, resulting in 72 families and 274 species. Of these species, 127 (46.4%) were marine species and 147 (53.6%) were estuarine-associated species. In terms of their life history and considering the habitat type classification, 188 (almost 70% of the total) were categorized as species inhabiting soft-bottom habitats, reflecting the large estuarine environment and rich fish diversity of the Gulf despite its relativel

Mesoscincus managuae (Dunn, 1933) (Squamata, Scincidae) is a typical dry-forest species found along the Pacific versant of Central America from Guatemala to northwestern Costa Rica. Here, we report the occurrence of this species on the Caribbean versant of Honduras, specifically on the Sula Plain, Deparment of Cortés. This is a subhumid habitat similar to others in the Mesoamerican region which have comparable herpetofauna assemblages and where M. managuae has already been recorded.

The persistence of the coat color polymorphism melanism has been reported for several tropical felids, but its evolutionary advantages remain an active area of research. Few publications have explored melanism in the elusive species, oncilla (Leopardus tigrinus) within the Neotropical part of their range in Costa Rica. Herein, I present the first record of a melanistic oncilla within the montane cloud forest of Monteverde, Costa Rica. Recent studies have found support for theories (e.g. Temporal Segregation Hypothesis and Gloger’s Rule) explaining the ecological advantages driving melanism in

Abstract:

AbstractThe maintenance of biodiversity in tropical forests is thought to be dependent on fine-scale mechanisms of niche partitioning that allow species to coexist. This study examined whether three species of short-tailed fruit bat that co-occur at a lowland tropical forest site in Costa Rica (Carollia castanea, C. perspicillata, C. sowelli) avoid inter- and intraspecific competition through dietary specialization on species in the genus Piper. First, dietary composition was examined using faecal samples (N = 210), which yielded three main findings: (1) bat species and sexes vary in overall r
