Abstract Surrounded by subducting slabs and continental keels, the upper mantle of the Pacific is largely prevented from mixing with surrounding areas. One possible outlet is beneath the southern part of the Central American isthmus, where regional observations of seismic anisotropy, temporal changes in isotopic composition of volcanic eruptions, and considerations of dynamic topography all suggest upper mantle flow from the Pacific to the Caribbean. We derive new constraints on the nature of seismic anisotropy in the upper mantle of southern Costa Rica from observations of birefringence in teleseismic shear waves. Fast and slow components separate by ∼1 s, with faster waves polarized along the 40°–50° (northeast) direction, near-orthogonally to the Central American convergent margin. Our results are consistent with upper mantle flow from the Pacific to the Caribbean and require an opening in the lithosphere subducting under the region.

The Central American frogs of the genus Craugastor consist of 113 species (Hedges et al. 2008; Frost 2011). Craugastor gollmeri (Peters) occurs in lowland to highland forests of central Panama, the Caribbean versant of western Panama and eastern Costa Rica, even extending into the Pacific versant in northwestern Costa Rica, within an altitudinal distribution range of 10–1520 m (Savage 2002). At some localities, C. gollmeri has been found to be an usual to common forest species, being primarily a diurnal species that inhabits leaf-litter on the forest floor (Ibáñez et al. 1995; Savage 2002). The snout-vent length (SVL) of adult frogs is 30–36.5 mm in males and 45–54 mm in females (Savage 1987). The males of gollmeri species group lack vocal slits and vocal sac (Savage 1987), and seem incapable of producing vocalizations (Savage 2002). Nonetheless, here we describe the vocalizations given by a male of C. gollmeri in captivity, considered to be advertisement calls (sensu Wells 1977). The role of advertisement calls in species recognition and reproductive isolation has been well established (Wells 2007), hence, the relevance of call characters in anuran phylogenetic and systematic studies (e.g., Hoskin 2004).

AbstractThe finding of ceremonial bone and shell objects at Puntarenas Farm, Jalaca, southeastern Costa Rica, along with ceramics of known Chiriqui or Red and Black ware, has thrown new light upon the extent of pre-Columbian trade and the penetration of cult traits from northern South America into lower Central America. Although no radiocarbon date has been obtained as yet, it is known that the manufacture of Chiriqui or Red and Black ware was continued into post-Columbian times.The presence in this region of shells found only on the Caribbean coast of Central America and not on the Pacific, as well as artifacts of manatee (Trichechus m. manatus Linn.) bone, also associated solely with the Caribbean littoral, indicate the extent and importance of trade. In the same sense, the appearance of the alligator-serpent motif on both coasts of the Nicoya Peninsula and on the western coast with ware related to Ulua Polychrome types and with an Ulua style alabaster vase, places a new northern boundary with respect to the diffusion of this cult motif. The Ulua Polychrome types and the Ulua style alabaster vase put a time horizon covering from A.D. 1000 probably to the Spanish arrival. The alligator-serpent concept, so familiar in the Amazon and Andean regions, the “eagle” or “condor” concept, the feline, the monkey, and the frog all emphasize the common base of lower Central American religion. Likewise they point to San Agustin as a cultural center of great importance in lower Central America.From the artistic point of view, the bone objects represent some of the most intricate carving yet known in eastern Central America. Both the style and subject matter place these figures in a different category from bone artifacts associated with Mesoamerican cultures.

AbstractDecapod crustaceans are a diverse group that exploits various types of habitats in Costa Rica, where they represent 8.1% of the marine diversity of the country. This group includes families containing species with strictly symbiotic behavior, e.g., the Palaemonidae and Pinnotheridae. Despite the high diversity of decapods and the importance of symbionts in marine ecosystems, very little research has been done regarding symbiosis in Costa Rica and the Central American region. The objective of the present study is to present a check list of the species of decapods that are associated with macroinvertebrates in Pacific Costa Rica. The research was carried out using different sources, including a literature review, the Crustaceans Collection of the Zoology Museum of the University of Costa Rica, and field surveys between 1970 and 2019 along the Pacific coast of Costa Rica, and Isla del Coco, 500 km offshore. One-hundred associations are reported, of 74 species of symbiotic decapods with six host phyla. Seventy-four associated with Cnidaria, 15 with Echinodermata, four each with Annelida and Mollusca, two with Chordata, and one with Porifera. In total, there were 14 new reports of decapods occurring on Isla del Coco and four new reports of decapods for Costa Rica: Pseudocoutierea elegans, Raytheres clavapedatus, Tuleariocaris holthuisi, and Calyptraeotheres pepeluisi. These results highlight the need to conduct more detailed studies to determine the real diversity and ecological importance of the associations between marine organisms.

A New Species

Based on differences in coloration, morphometrics, and scalation, I recognize seven species of anoles related to Anolis pentaprion in Central America: Anolis beckeri (southeastern Mexico to northern Nicaragua), A. cristifer (Pacific lowlands of Chiapas to central Guatemala), A. fungosus (Caribbean premontane zone from central Costa Rica to western Panama), A. pentaprion (Caribbean lowlands of southern Nicaragua to northwestern Colombia, also on Pacific versant in central and eastern Panama), A. salvini (Pacific premontane and lower montane zones from central Costa Rica to western Panama), A. utilensis (restricted to Isla de Utila, Honduras), and a new species (from the Pacific lowlands of Costa Rica and western Panama) described herein. The new species differs from A. pentaprion by having a red male dewlap with few large, widely spaced gorgetal scales scattered across the dewlap (pink with purple pigment between rows of gorgetals, and with regular rows of numerous small, narrowly spaced gorgetal scales in A. pentaprion). Furthermore, I resurrect the name A. beckeri Boulenger for the pentaprion-like populations of anoles distributed from southeastern Mexico to northern Nicaragua. Anolis beckeri differs from A. pentaprion most obviously in the dorsal tail scalation (a serrated caudal crest present in A. pentaprion versus no such crest in A. beckeri) and dewlap scalation (gorgetal rows with 17–25 narrowly spaced scales in A. pentaprion versus gorgetal rows with 4–10 widely spaced scales in A. beckeri). Finally, SMF 83608 is proposed as the neotype for Anolis pentaprion. I provide standardized descriptions of A. beckeri, A. pentaprion, and the new species described herein.

A New Species

A new species of Roeboides is described from the Pacific slope of Costa Rica and Panama. Roeboides bussingi differs from all other Central American Roeboides and all members of the R. guatemalensis species group by the following combination of characters: presence of 18-22 scales above the lateral line (vs. 12-16 in R. dientito); 15-22 scales below the lateral line (vs. 10-14 in R. dientito, and 20-24 in R. loftini); an inconspicuous, sometimes absent, crescent-shaped humeral spot (vs. a large round, conspicuous humeral spot in R. carti, R. dayi, R. dientonito, R. ilseae, R. loftini,and R. occidentalis); a small wedge-shaped spot that does not reach the lateral line (vs. a large spot crossing the lateral line in R. guatemalensis); a teardrop shaped caudal spot (vs. caudal spot triangle shaped in R. bouchellei); and a dark band at the distal tip of the anal fin (vs. dark band absent in R. bouchellei). A key to all Middle American species of Roeboides is also presented

Due to the importance of primary production in the trophic network, most aquatic ecosystems rely on microalgae. However, there are fewer studies on phytoplankton in the Central American region, specifically on marine diatoms, in part because it is difficult to isolate and cultivate local species in tropical climates. The objective of this study is the isolation of two local diatoms of Chaetoceros and Nitzschia, potential food for aquatic organisms. Water samples was taken from the Nicoya Gulf, located in the Central Pacific coast of Costa Rica. The samples were successively filtered first through a 35µm pore size filter and then through one of 20µm. They were repeatedly isolated using modified Pasteur pipettes, and serial dilutions were done until a monoalgal culture was obtained. Two Bacillariophyceae were isolated: NGN1, genus Nitzschia; and CGN2, genus Chaetoceros. This study is a step toward reducing the importation of phytoplankton on feeding aquatic organisms by providing technical and scientific information to develop a microalgal culture from this region.

Contrast Information

The authors challenge the argument by other world-system scholars that Lower Central America fell outside the Mesoamerican world-system during the late Postclassic period. Drawing on ethnohistoric and archaeological information, it is argued that native peoples along the Pacific Coast of Central America from El Salvador to the Nicoya Peninsula (Costa Rica) are best understood as part of the Mesoamerican periphery. The Central American peoples south of Nicoya formed both a chiefly world-system of their own and part of the Mesoamerican frontier by engaging in networks of trade and preciosity exchanges with the coastal Mesoamericans in Nicoya and Nicaragua. Support for this argument is based primarily on two “microhistoric” case studies of peoples located on both sides of the Mesoamerican/Lower Central America border, specifically the Chorotegans of the Masaya/Granada area of Nicaragua and the Chibchans of the Diquis/Buenos Aires area of Costa Rica. Archaeological information on sites in both areas and documentation from Spanish colonial sources that refer to native peoples in these areas strongly indicate that the Masaya/Granada peoples were active participants in the Mesoamerican regional network. In contrast, information from the Diquis/Buenos Aires area for this period reveals only weak Mesoamerican ties but strong relations with a Chibchan intersocietal network of chiefdoms.
