AbstractPatch depletion is an assumption that underlies many behavioural ecological models, yet it has rarely been examined. The evidence presented here suggests that the spider and howling monkeys of Santa Rosa National Park, Costa Rica use food resources that occur in patches and generally deplete the patches they use. However, some types of patches (e.g. large fruiting trees for spider monkeys, and trees used as sources of leaves for howlers) are not depleted by the feeding activity of primates. An examination of which types of patches are depleted and the manner in which depletion likely occurs, allows an assessment of possible factors underlying the different types of social organizations in these species.

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.

The presence of a Panamanian species, A. championi Bates, in Costa Rica, as noted by Max Liebke has been confirmed (Agra danjanzeni Erwin = A. championi Bates, new synonymy). Also included: Neotype designation for Agra pia Liebke 1940 and apparent rediscovery of this species in Costa Rica; Agra aurifera Liebke 1940 description translated from the German and reproduced here with comments.

<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>

AbstractWhen spider monkeys (Ateles geoffroyi) are dispersed and moving through wooded areas in the dry forest of Santa Rosa National Park in Costa Rica, they give loud calls, whinnies, that can be heard over long distances and appear to be answered with the same call from other monkeys. We examined the circumstances in which this vocalization was emitted and the responses elicited from other group members. A total of 105 h of continuous recordings on emission of whinnies, 113 h of individual focal samples and 291 spectrograms were analyzed from a study group with 15 identified subjects. Whinnies emitted in different circumstances caused different reactions. Whinnies provoked by the sight of an observer were never responded to in any particular way, while those given during resting or feeding sometimes caused an active response of approach or calling. Most strikingly, whinnies given during group movement provoked hearers to approach or call significantly more often than either those given while feeding or resting. Playback experiments found one response, 'scan', to differ according to the original circumstances of emission of the broadcast call: monkeys scanned more in the direction of the sound when hearing feeding rather than group movement whinnies.
