Santa Rosa National Park

 Santa Rosa National Park, Guanacaste Province, protects one of the largest remnants of dry forest in Mesoamerica. It is considered an example of how to regenerate forest in an area that for many years was used for cattle. A proper management requires knowledge of trends in mammal populations. We chose species that demand high ecologic integrity. the jaguar (Panthera onca ) and other felines, and their potential prey. Using trace count we assessed abundance on seven trails systematically sampled in 2001 and later in 2011. In 2011 we found more traces of jaguars, less of cougars and the same number for ocelots. In the second sampling we found less herbivores and frugivores, and more omnivores. We believe that the trace method is reliable, rapid and cheap.

AbstractThe Campanian rudist fauna identified from the localities Playa Panamá, Santa Rosa National Park, Colorado de Abangares, and Bolsón in Guanacaste Province, Costa Rica, is composed of the antillocaprinidsAntillocaprinasp. aff.A. suboccidentalisChubb, 1967,Antillocaprinasp. and Antillocaprinidae indet.; the multiple-fold hippuritidsBarrettia moniliferaWoodward, 1862,Parastroma trechmanniChubb, 1967, and cf.Whitfieldiella gigas(Chubb, 1955); the plagioptychidsPlagioptychus trechmanniChubb, 1956,Plagioptychussp. cf.P. zansiChubb, 1956,Mitrocaprina costaricaensisnew species,Mitrocaprina multicanaliculataChubb, 1956, and Plagioptychidae indet.; and the radiolitidsRadiolitessp. aff.R. multicostata(Adkins, 1930),Alencasteritesnew genusmooretownensis(Trechmann, 1924),Bournonia?tetrahedron(Chubb, 1967),Chiapasellasp.,Guanacastea costaricaensisnew genus new species, cf.Potositessp. aff.P. tristantorresiAlencáster and Pons in Pons et al., 2010, and aff.Thyrastylonsp. Although some differences in rudist diversity and sedimentary setting were observed among localities, most species indicate the same age for all occurrences, which correspond to the Campanian, probably mid-Campanian. Radiolitid specimens appear better preserved than those of other taxa and are thus discussed more in detail. Both the number of radiolitid genera exclusively known from the New World, and reasonable doubts about the correct attribution of some New World species to Old World genera, indicate important differences between rudist faunas at both sides of the Atlantic (Mediterranean and American Tethys, respectively) during the Late Cretaceous.

Corcovado National Park

The jaguar Panthera onca is threatened throughout its range and categorized as Near Threatened on the IUCN Red List. To inform conservation of the jaguar population in Corcovado National Park, Costa Rica, population size was estimated using data from a 3-month camera trap study. Individuals were identified from their coat patterns. The resulting density estimate of 6.98 ± SD 2.36 individuals per 100 km2 was lower than expected. The sex ratio was 1.33 males per female, and the minimum home ranges of two males were 25.64 and 6.57 km2. Hunting pressure on jaguar and white-lipped peccaries Tayassu pecari, the jaguar's main prey in the Park, may be responsible for the low jaguar density as space does not seem to be a limiting factor. The numbers of females may have been underestimated because of sampling bias and therefore the sex ratio obtained in this and similar studies must be interpreted cautiously. Better protection of the corridor that connects the Park with other protected areas is essential to guarantee long-term survival of the jaguar in Costa Rica.

The Past

Understanding the abundance, geographicdistribution, and conservation status of terrestrial mam­mals is vital to promote effective wildlife management in protected areas. Located in the Tumbes-Chocó-Magdalena hotspot of western Ecuador, Machalilla National Park contains high levels of biodiversity and endemism but suffers from habitat loss and degradation. This study provides an updated inventory of medium-sized to large mammals in the park and assesses changes in species richness over the past 20 years. Surveying 70% of Machalilla’s 562-km2 terrestrial area with 60 camera trap points, we detected 18 species of mammals belonging to 13 families. Richness of terrestrial species has declined in recent decades, due to the disappearance of keystone species like Jaguar (Panthera onca), White-lipped Peccary (Tayassu pecari), and possibly the Sechuran Fox (Lycalopex sechurae). We recommend specific man­agement improvements to ensure conservation of the unique ecosystems and biodiversity of Machalilla, the only national park in Ecuador containing dry forest.

<p>La mayoría de los manglares del Pacífico Norte de Costa Rica son de los más impactados en el país. Además, la información científica sobre la fisiología, ecología, estructura y geoquímica de estos manglares es limitada. Este estudio analizó la complejidad estructural y composición de especies de dos bosques de manglar del Pacífico Norte: Potrero Grande y Santa Elena. Las visitas al campo se realizaron entre mayo y junio del 2012. Se utilizó el método deCuadrantes Centrados en un Punto (PCQM) para estudiar la estructura del bosque. Se anotó las especies de mangle, altura, diámetro a la altura del pecho (DAP) y densidad del dosel en diez puntos a lo largo de cada transecto. Así mismo, se registró la fauna asociada y cobertura de macroalgas epífitas sobre las raíces de mangle. En cada punto se determinó la salinidad de agua intersticial. Se calculó la densidad, área basal, dominancia, valor de importancia e índice de complejidad. <em>Rhizophora racemosa</em> fue la especie con mayor dominancia relativa y valor de importancia para ambos sitios. Santa Elena es el manglar con el mayor índice de complejidad (IC=26.9), lo cual podría deberse a la alta densidad encontrada. Potrero Grande es considerado como uno de los manglares más desarrollados de la costa del Pacífico Norte de Costa Rica, dadas sus características estructurales (árboles con grandes alturas y DAP)y de composición de especies. La distribución conocida de <em>Pelliciera rhizophorae</em> en Costa Rica alcanzaba su límite norte en el manglar de Potrero Grande; sin embargo, este estudio extiende esta distribución más al norte, ya que se encontraron algunos individuos en Santa Elena. A diferencia de Potrero Grande, Santa Elena no cuenta con un sector marino protegido adyacente, esto ha resultado en la extracción de recursos y actividades turísticas incontroladas en la zona. Se recomienda la creación de un área de protección marina en la Bahía de Santa Elena para que sirva de zona de amortiguamiento al manglar.</p>
