A new Costa Rican species of Drosophila visiting inflorescences of the hemi-epiphytic climber Monstera lentii (Araceae) Rev. Bras. entomol.
Vilela,Carlos R.; Prieto,Danyi.
ABSTRACT Drosophila monsterae sp. nov. is described from 11 males and 13 females collected from the inside of closed inflorescences of Monstera lentii (Araceae) at 1810 m altitude in the Forest Reserve of Cerro de La Carpintera, Canton La Unión, Province of Cartago, Costa Rica. Although flies have been seen wandering and copulating inside the floral chambers of closed inflorescences during the floral female phase, eggs or larvae have not yet been found either in the spathe or in the fleshy spadix. The new species is related to Drosophila tristani Sturtevant, 1921, from San José, Costa Rica, from which it differs mainly by having smaller slightly circular compound eyes, distinctly broader genae (cheek index ca. 2.4 vs 5 in D. tristani), and the inner...

Circumscription and nomenclature of Hiraea barclayana, H. reclinata, and H. ternifolia (Malpighiaceae), and of seven species misassigned to them Naturalis
Anderson, C..
A review of collections from Mexico to northern South America that had been primarily determined as H. barclayana, H. reclinata, and H. ternifolia, or synonyms, showed them to include ten species. Misinterpretations were caused by superficial morphological similarities and traditional nomenclatural errors. The species now recognized include six previously described: H. barclayana, H. hookeriana (formerly included in H. reclinata), H. reclinata, H. sanctae-marthae, H. ternifolia, and H. transiens. Four new species are proposed: H. mcvaughii, H. silvicola, and H. venezuelana; H. trianae was previously recognized at varietal level and is elevated to species. A neotype is chosen for H. reclinata. Lectotypes are designated for H. velutina (= H. barclayana) and...

Current challenges for confronting the public health problem of snakebite envenoming in Central America J. Venom. Anim. Toxins incl. Trop. Dis.
Gutiérrez,José María.
Snakebite envenoming is a serious public health problem in Central America, where approximately 5,500 cases occur every year. Panama has the highest incidence and El Salvador the lowest. The majority, and most severe, cases are inflicted by the pit viper Bothrops asper (family Viperidae), locally known as ‘terciopelo’, ‘barba amarilla’ or ‘equis’. About 1% of the bites are caused by coral snakes of the genus Micrurus (family Elapidae). Despite significant and successful efforts in Central America regarding snakebite envenomings in the areas of research, antivenom manufacture and quality control, training of health professionals in the diagnosis and clinical management of bites, and prevention of snakebites, much remains to be done in order to further...

Do Farmers Benefit from Participating in Specialty Markets and Cooperatives? The Case of Coffee Marketing in Costa Rica AgEcon
Wollni, Meike; Zeller, Manfred.
Historically low prices in the conventional coffee market have caused financial and social hardship among coffee farmers. In the face of this crisis, specialty markets have attracted the attention of the international donor community. These market segments have shown consistent growth over the last decade and exhibit price premiums in international markets. Therefore, if higher prices are passed on to farmers, access to specialty markets could help to alleviate the crisis brought on by low prices in the conventional sector. The present study attempts to identify the factors that determine farmers' participation in specialized markets and whether participation in these markets leads to higher prices for farmers. A two-stage model is used to analyze farmers'...

Edge-drilling behavior in the predatory gastropod Notocochlis unifasciata (Lamarck, 1822) (Caenogastropoda, Naticidae) from the Pacific coast of Panama: taxonomic and biogeographical implications Naturalis
Rojas, Alexis; Hendy, Austin; Dietl, Gergory P..
We conducted a laboratory study to determine drillhole siteselectivity patterns in the predatory behavior of Notocochlis unifasciata (Lamarck, 1822), which is a common naticid gastropod on the eastern Pacific coast of Central America, preying on two infaunal venerid bivalves – the thin-shelled and weakly ornamented Leukoma grata (Say, 1831) and the thick-shelled and strongly ornamented Iliochione subrugosa (Wood, 1828). Spatial patterns of drillhole distribution indicate strong preferences for drilling the umbonal region and the ventral edge of the shell, with the proportion of edge- to wall-drilling attacks increasing in thicker, strongly ornamented prey that were larger than their predator’s own size. Drilling patterns from museum and beach...

Farmer Organization, Collective Action and Market Access in Meso-America AgEcon
Hellin, Jonathan; Lundy, Mark; Meijer, Madelon.
The global agricultural economy is changing. Commodity prices are declining, and producers increasingly supply complex value chains. There is growing interest in how farmers can benefit from emerging market opportunities. Farmers are encouraged to produce high value crops and engage in value-adding activities such as agro-processing. Farmer organization and collective action are often seen as key factors in enhancing farmers’ access to markets. Often too little attention is directed at a) the most appropriate types of organization, b) whether the public and/or private sector is best placed to support their formation, and c) the conditions necessary for ensuring their economic viability. This paper reports on research in Mexico and Central America that...

Reproductive life history of Heterandria bimaculata (Heckel, 1848) (Poeciliinae: Poeciliidae) in the Honduran interior highlands: trait variation along an elevational gradient Neotropical Ichthyology
Olinger,Charles T.; Peoples,Brandon K.; Frimpong,Emmanuel A..
Abstract This study examined reproductive traits and growth rates of Heterandria bimaculata (Poeciliidae) in Cusuco National Park (CNP), a cloud forest reserve in northern Honduras, Central America. In CNP, H. bimaculata occurs in the absence of other fish species and major invertebrate predators along an approximately 1000 m elevation gradient. This allowed for the examination of trait variation along the gradient without the confounding effects of interspecific interactions or habitat patchiness. Heterandria bimaculata exhibited traits characteristic of a low-predation environment: balanced sex ratio, slow growth, late maturity and large female size. Females produced more, smaller eggs from upstream to downstream, but overall reproductive allocation...

Scorpionism in Central America, with special reference to the case of Panama J. Venom. Anim. Toxins incl. Trop. Dis.
Borges,A; Miranda,RJ; Pascale,JM.
Scorpionism in the Americas occurs mainly in Mexico, northern South America and southeast Brazil. This article reviews the local scorpion fauna, available health statistics, and the literature to assess scorpionism in Central America. Notwithstanding its high toxicity in Mexico, most scorpion sting cases in Guatemala, Belize, El Salvador, Nicaragua, and Costa Rica are produced by species in the genus Centruroides that are only mildly toxic to humans despite the existence of ion channel-active toxins in their venoms. Regional morbidity is low with the exception of Panama, where an incidence of 52 cases per 100,000 inhabitants was recorded for 2007, with 28 deaths from 1998 to 2006. Taxa belonging to the genus Tityus (also present in the Atlantic coast of...

Soil conservation and technical efficiency among hillside farmers in Central America: a switching regression model AgEcon
Solis, Daniel; Bravo-Ureta, Boris E.; Quiroga, Ricardo E..
The main objective of this paper is to evaluate and analyse technical efficiency (TE) levels for hillside farmers under different levels of adoption of soil conservation in El Salvador and Honduras. A switching regression model is implemented to examine potential selectivity bias for high and low level adopters, and separate stochastic production frontiers, corrected for selectivity bias, are estimated for each group. The main results indicate that households with above-average adoption show statistically higher average TE than those with lower adoption. Households with higher adoption have smaller farms and display the highest partial output elasticity for land. Constraints in the land and credit markets are likely explanations for these differences. In...
