Abstract:

AbstractThe Cretaceous period was marked by the most voluminous episodes of oceanic plateau volcanism in the Phanerozoic Eon. Primarily affecting the Pacific, mantle plumes generated oceanic plateaus during three main phases (ca. 145–140 Ma, ca. 122–115 Ma, and ca. 100–90 Ma). Central America is one of the very few circum-Pacific margins where remnants of these Cretaceous plateaus were accreted. The study of their onland exposures provides a highly valuable insight into the complexity and diversity of oceanic plateau histories, from their eruption to their accretion. Exposed in northern Costa Rica, the plateau remnants of the Nicoya Peninsula originated from a Jurassic oceanic crust over-thickened by Early and Late Cretaceous hotspots. These sheared-off pieces of the Farallon Plate testify to the early tectonic interaction of the Caribbean Large Igneous Province (CLIP, ca. 94–89 Ma) with North America, initiated <5 m.y. after the onset of CLIP eruption. By combining our results with previously published data, we propose an updated tectono-stratigraphic framework that divides the Nicoya Peninsula into two oceanic plateau terranes. (1) The accretion timing of the Aptian to Turonian Manzanillo Terrane is constrained by the Coniacian (ca. 89–86 Ma) base of the overlapping Loma Chumico Formation. The proximal tuffaceous forearc deposits of the Loma Chumico Formation are the oldest evidence of a volcanic arc in Costa Rica—called here the Berrugate Arc—as revealed by new biostratigraphic and geochemical data. (2) The Nicoya Complex s. str. is a composite plateau remnant containing rocks of Bajocian to earliest Campanian age. Its accretion occurred during the middle Campanian (ca. 79–76 Ma) and shut down the Berrugate Arc. In contrast to the collision of CLIP with North America, onset of the collision of CLIP with South America began much later, during the latest Campanian (ca. 75–73 Ma).

Abstract:

Introduction: The Gulf of Nicoya is the most important estuary on the Pacific coast of Costa Rica. Information on the presence of soft corals is scattered in the literature and in museum collections. Objective: To provide a list of soft corals reported for the estuary. Methods: We compiled the literature (2002-2020) and of the specimens deposited at the Museum of Zoology, University of Costa Rica. Results: Thirty species have been reported for the estuary (Clavulariidae, Gorgoniidae and Plexauridae). Most were collected on the eastern coast of the Nicoya Peninsula, and several species were described based on estuary specimens. Conclusion: The 30 species represent 79 % of those reported for Costa Rica. Despite this relatively high percentage, the sampling effort has been modest and other sites within the estuary should be explored.

Abstract:

(1) Background: Longevity Blue Zones (LBZs) are populations characterized by exceptional longevity. The purpose of this cross-sectional study was to compare the food habits of two representative samples of the oldest old subjects from the population residing in the LBZs of Nicoya peninsula (Costa Rica) and in the mountainous part of Ogliastra (Sardinia, Italy). (2) Methods: Data were collected using validated tools, including a food frequency questionnaire, Basic Activities of Daily Living (BADL) and Instrumental Activities of Daily Living (IADL) scales for functional autonomy, body mass index, and waist and limbs circumferences. (3) Results: A total of 210 subjects, 60 (31 male) from Nicoya (age range 80–109 years), and 150 (61 male) from Ogliastra (age 90–101 years) were included in the study. In both populations, the highest frequencies of consumption were recorded for plant-derived foods (cereals 60–80% daily, legumes ≥ 80% daily in Nicoya, ≥ 60% 2–5 servings/week in Ogliastra), followed by those of animal origin (dairy products, meat) ≥60% and 80% daily, in Nicoya and Ogliastra, respectively. The frequency of milk consumption showed a positive correlation with BADL (ρ = 0.268 for Nicoya and ρ = 0.214 for Ogliastra) and IADL scores (ρ = 0.466 for Nicoya and ρ = 0.471 for Ogliastra), whereas legumes consumption correlated negatively with self-rated health (ρ = −0.264) and IADL (ρ = −0.332). (4) Conclusions: Our results indicate that the dominant dietary model among the elderly of Nicoya and Ogliastra is a plant-based diet complemented by a non-negligible consumption of animal products, mostly dairy products. Further prospective studies are needed to ascertain a possible cause–effect relationship between food habits and increased likelihood of reaching advanced age.

Abstract:

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.

Abstract:

The town of Nosara on Costa Rica’s Nicoya peninsula is home to a vibrant community of diverse residents and is adjacent to an important turtle nesting site. However, tensions between lifelong residents, more recent transplants, visitors, and developers have increased as more of the world discovers this once-isolated haven. Climate change, income inequality, and alienation from a distant government apparatus have further complicated effective land-use planning and fractured social cohesion. Using a mixed-method approach of in-depth interviews (n = 67), Q methodology (n = 79), and public deliberation (n = 88), we explored residents’ priorities for the future of their town. The results indicate four different perspectives on Nosara’s future. Despite the tensions among those four perspectives, they show consensus on one overarching community issue: the need for a sustainable development plan. The case also shows how Q-methodology can assist scholars and practitioners who embrace participatory approaches to policy development and conflict resolution in the environmental arena.

Full text

Abstract:

A new species of Moribaetis is described based on nymphs from the Nicoya peninsula. The new species can be distinguished from the other described species of the genus, among other characteristics, by its short antennae, strongly curved lateral branches of the epicranial suture, long mandibular incisors projected beyond labrum margin, violet-colored gills, and a distinctive triangular projection on paraproct. Moribaetis brachiostrinus, M. macaferti and M. salvini share certain characters that set them apart from M. maculipennis suggesting that the latter represents a separate branch within this genus. M. brachiostrinus has the lowest altitudinal distribution of the genus in Costa Rica and represents the first record of a Moribaetis occurring on the oldest emerged lands in the country. Comments on the age-related changes in the mandibular incisors and a key to mature nymph of Moribaetis species are also provided.

Abstract:

A survey of the amphibians and reptiles of Reserva Natural Absoluta Cabo Blanco (RNACB), Puntarenas, Costa Rica was conducted from May to August 2003. Thirteen amphibian and 19 reptile species were found within the RNACB boundaries. Twenty-two of these species were not previously recorded from the lower Nicoya Peninsula and for seven, this locality represents the southernmost extension of their range. One additional amphibian and three reptile species are known from the area based on literature review and examination of museum collections. However, interviews with locals indicate that up to nine other reptile species could be present in the reserve. I observed all but one amphibian species at Laguna Balsitas and at least eight species utilize the lagoon for reproduction. The lagoon is also notable for its population of Kinosternon scorpioides. This study will provide a baseline for further research in the reserve.

Abstract:

‘Pliocardia' krylovata, sp. nov. (Bivalvia: Vesicomyidae: Pliocardiinae) is described from cold seeps off the coast of the Nicoya Peninsula, Costa Rica (700–1000 m depth). The phylogenetic position of‘P.' krylovatawas assessed by both morphological comparisons as well as nucleotide data from the cytochrome c oxidase I gene. Within the vesicomyids,‘P.' krylovatabelongs to the Pliocardiinae and its closest relative is‘Calyptogena' ponderosa, which also bears some morphological resemblance to the genusPliocardia, perhaps suggesting a need for reanalysis of not only its generic designation, but also the entire Pliocardiinae subfamily.‘P.' krylovatahas morphological similarities to‘Pliocardia' bowdenianaand‘Vesicomya' crenulomarginata, recently reassigned to the genusPliocardia, including a thick shell, obvious rostrum, pointed posterior end, and a sculptured shell with concentric ribs on the outer surface, to name a few. It is morphologically distinguished, however, by having a complex pallial sinus and remarkably deep escutcheon.

Full text

Abstract:

A multichannel seismic reflection profile across the oceanic crust seaward of the Middle America Trench off the Nicoya Peninsula, Costa Rica, shows discontinuous, low‐frequency events at 6.5 to 7.0 s. These events might first be interpreted as reflections from the Moho. However, careful analysis of the seismic data suggests that these events represent three‐dimensional (3-D) scattered energy from the rough basaltic basement. Velocity analysis indicates that root‐mean‐square (rms) velocities for these deep “reflection events” are too low to emanate from the Moho. Also, the ghost separation caused by the streamer depth decreases for increasing record time, suggesting that incident angle for these “reflections” increases with time. Furthermore, these events are approximately 13 dB stronger than would be expected for a Moho reflection. Common‐depth‐point (CDP) stacking and velocity filtering were used to attenuate the scattered noise and sideswipe from the basalt. The results show a 21 dB total reduction of scattered energy. However, Moho reflections still cannot be discerned. The results suggest (1) ambient noise after processing is 20 dB below the expected Moho level and is not a factor in detection of the Moho; (2) Moho reflectivity may be smaller than 0.1 (reflectivity is calculated from assumed velocities and densities) and could be as small as 0.05 (the detection threshold); (3) the Moho may not be a discrete reflector and may therefore represent a transition zone; and (4) Moho events may be disorganized by transmission through rough basalt so the CDP stacking process is not effective.

Abstract:

El turismo como actividad esencial dentro de la economía de Costa Rica desde la década de los años ochenta, ha contribuido en el desarrollo de diversas comunidades en todo el país. A pesar de la importancia de la actividad turística muchos gobiernos locales no han implementado instrumentos de planificación territorial como el plan regulador o a nivel sectorial como planes de desarrollo turístico que favorezcan el avance de la misma.Con el fin de apoyar a las comunidades locales en la implementación de actividades turísticas esta comunicación se establece como objetivo, presentar una propuesta de planificación turística para las comunidades de isla de Chira, Corral de Piedra y San Juan localizadas en el golfo y la península de Nicoya, Costa Rica. Para ello, se aplica una estrategia de planificación que permite delimitar zonas turísticas en dichas comunidades. A partir del análisis del sistema turístico, se establece la vocación de los recursos turísticos, se caracteriza la demanda y oferta turística e identifican los principales actores asociados a la actividad en la zona, para identificar los elementos homogeneizadores del espacio que permiten proponer zonas de planificación turística.

Abstract:

Many conservation projects relocate sea turtle eggs to hatcheries to protect the sea turtle nests from the anthropogenic and natural threats they face in the early stages of development. The Rescue Center for Endangered Marine Species (CREMA) manages four sea turtle conservation projects on the nesting beaches of the Southern Nicoya Peninsula in Costa Rica, where the predominant nesting activity is from olive ridley turtles (Lepidochelys olivacea). Two of these nesting projects are based in Costa de Oro and San Miguel, which are adjacent beaches divided by an estuary. In this study, we compared the dynamics and rates of human and animal predation of nests prior to being relocated to the hatchery on both nesting beaches from 2012 to 2018. We hypothesized that human take and animal predation were compensatory threats, meaning that lower human take may result in higher animal predation, and vice versa, resulting in a similar number of nests lost to predation overall. We discuss the community-based conservation programs on both beaches, one of which has been monitored since 1998 (San Miguel) and the other of which has been monitored since 2012 (Costa de Oro). We found that Costa de Oro exhibited high rates of human take with up to 51% of nests being extracted per season, which has decreased since the conservation project was established. Human take was significantly higher than animal predation on both beaches and human take was significantly higher in Costa de Oro. While San Miguel exhibited higher animal predation, the difference was not statistically significant. Higher depredation by animals corresponded to higher overall nest abundance on both beaches. We were unable to find evidence that human take or animal predation increased in the absence of the other threat, suggesting a lack of compensatory effects of predation. Our findings support further analysis of animal predation and a continuation of patrol-based conservation efforts as well as community outreach to attempt to merge cultural values with sea turtle conservation.

Abstract:

Abstract. Large amounts of methane are delivered by fluids through the erosive forearc of the convergent margin offshore Costa Rica and lead to the formation of cold seeps at the sediment surface. Besides mud extrusion, numerous cold seeps are created by landslides induced by seamount subduction or fluid migration along major faults. Most of the dissolved methane reaching the seafloor at cold seeps is oxidized within the benthic microbial methane filter by anaerobic oxidation of methane (AOM). Measurements of AOM and sulfate reduction as well as numerical modeling of porewater profiles revealed a highly active and efficient benthic methane filter at Quepos Slide site; a landslide on the continental slope between the Nicoya and Osa Peninsula. Integrated areal rates of AOM ranged from 12.9 ± 6.0 to 45.2 ± 11.5 mmol m-2 d-1, with only 1 to 2.5% of the upward methane flux being released into the water column. Additionally, two parallel sediment cores from Quepos Slide were used for in vitro experiments in a recently developed Sediment-F low-Through (SLOT) system to simulate an increased fluid and methane flux from the bottom of the sediment core. The benthic methane filter revealed a high adaptability whereby the methane oxidation efficiency responded to the increased fluid flow within 150–170 days. To our knowledge, this study provides the first estimation of the natural biogeochemical response of seep sediments to changes in fluid flow.

Abstract:

In subduction zones, elevated pore fluid pressure, generally linked to metamorphic dehydration reactions, has a profound influence on the mechanical behavior of the plate interface and forearc crust through its control on effective stress. We use seismic noise–based monitoring to characterize seismic velocity variations following the 2012 Nicoya Peninsula, Costa Rica earthquake [Mw(moment magnitude) 7.6] that we attribute to the presence of pressurized pore fluids. Our study reveals a strong velocity reduction (~0.6%) in a region where previous work identified high forearc pore fluid pressure. The depth of this velocity reduction is constrained to be below 5 km and therefore not the result of near-surface damage due to strong ground motions; rather, we posit that it is caused by fracturing of the fluid-pressurized weakened crust due to dynamic stresses. Although pressurized fluids have been implicated in causing coseismic velocity reductions beneath the Japanese volcanic arc, this is the first report of a similar phenomenon in a subduction zone setting. It demonstrates the potential to identify pressurized fluids in subduction zones using temporal variations of seismic velocity inferred from ambient seismic noise correlations.

Abstract:

Conventional Kirchhoff migration methods are applied to seismograms in the offset‐time (x − t) domain. We describe the theory, numerical details, and examples of a prestack depth migration method in the plane‐wave domain that is valid in laterally inhomogeneous media. The theory is based on a Kirchhoff‐Helmholtz formulation of the wavefield and uses plane‐wave‐transformed shot gathers for migration. We use geometric ray theory for the source wavefield continuation operator and a plane‐wave expansion of the receiver wavefield in the integrand of the Kirchhoff‐Helmholtz integral. The source and receiver plane‐wave traveltimes are computed at each grid point in the subsurface using a finite‐difference approximation of the eikonal equation with appropriate initial and boundary conditions. We developed an efficient technique to compute imaging time by a combination of these two times. The technique allows us to design algorithms for migrating shot gather or constant ray‐parameter sections efficiently. We evaluate the efficiency and accuracy of the algorithm with three sets of synthetic data examples with varying degrees of complexity. We also compare the performance of the parallel algorithms using Parallel Virtual Machine (PVM). Migration of a marine data set results in excellent images of a mud volcano and the top of an accretionary prism of an active continental margin on the Nicoya Peninsula of Costa Rica.
