The gastropod Pachyoliva columellaris (formerly Olivella columellaris) is particularly common on many sandy beaches in North Peru. In the studied region north of Paita, Piura province, the species reaches densities of over 80000 individuals per beach meter. The snails perform tidal migrations throughout the lunar cycle although tidal amplitudes differ four-fold between neap and spring tide. Not all animals complete their tidal migrations, and significant numbers remain above the water line at low tide. Throughout the tidal cycle, the proportion of small individuals is increased near the water line whereas large animals dominate in lower beach zones. I conclude that the sandy beaches north of Paita are well-suited for further studies of P. columellaris and the mechanisms underlying tidal migrations in invertebrates.

Aunque la familia de las orquídeas es uno de los grupos de plantas mejor representados en los listados de conservación a nivel mundial, aun este número de representantes es pequeño considerando su alta diversidad y vulnerabilidad. Esto es particularmente notorio en los listados de la flora amenazada del Perú. En el presente comentario se analiza la representatividad de las orquídeas, con foco en las especies del género Telipogon incluidas en los listados de categorización de conservación en el Perú, enfatizando la importancia de realizar correctos listados y categorizaciones coherentes con las metas Aichi del Plan Estratégico para la Diversidad Biológica 2011-2020.

En el Perú se registran al menos 180 especies de murciélagos. Sin embargo, son pocos los estudios acerca de sus ectoparásitos, dentro de los cuales destacan las denominadas moscas de murciélagos (Diptera: Streblidae y Nycteribiidae), en los cuales se estima un total de 158 especies en la región Neotropical. En el Perú, una de las regiones con menos información es la costa. En este estudio actualizamos el conocimiento de las asociaciones ectoparásito-hospedero en murciélagos de la costa peruana, una de las regiones ecologicas con más degradación y pérdida de hábitat. Se evaluaron cinco localidades en las regiones de Piura, Lima y Tacna. Se capturaron 85 murciélagos pertenecientes a 7 especies; 4 de Phyllostomidae, 2 de Molossidae y 1 de Vespertilionidae. Se encontraron seis especies de dípteros (Diptera: Streblidae) y un hemíptero (Hemiptera: Polyctenidae) y se reporta por primera vez algunas de estas asociaciones en las regiones de Lima y Piura. Se reporta también a Anoura peruana como hospedero de Anastrebla modestini (Streblidae) en una colonia reproductiva compartida con Platalina genovensium, y por primera vez para la región de Piura, el co-parasitismo de los estréblidos Megistopoda aranea, Aspidoptera phyllostomatis y Metelasmus pseudopterus en un mismo individuo de Artibeus fraterculus.

Population growth, climate change and global warming are the great challenges facing agriculture in the 21st century. Therefore, it is necessary to increase the efficiency of selection of new varieties in plant breeding programs. In this regard, flow cytometry has proven to be a very powerful tool to speed-up selection processes in plant breeding because of its versatility and capacity to evaluate large populations.

Intellectual Property is a powerful legal and economic instrument. In our “knowledge economy”, patents are the preferred IP tool with special emphasis in the pharma – agro biotech industry. However, the growth of patents in the bio sector such as the pharma and agro fields, encounters many challenges. Life itself has not been defined yet. So, how can it be determined exactly when a living being, or a biological entity has been modified by itself or by human intervention, and thus address issues of patentability? Therefore, a researcher in the bio field cannot be alien to Intellectual Property, being the main actor in the revolution of the bio-pharma-agro sectors.

Reviews on biotechnological chitin recovery from crustacean waste and other sources acknowledge. Most of the reviews conclude that although important results on chitin recovery have been achieved, there is still a need for better approaches to improve operational conditions of deproteinization and demineralization processes, such as time, carbon source, pH (initial and during fermentation), volume of inoculum, temperature, among others, in order to apply at industrial level, a bioprocess commercially and environmentally cost/effective viable. The present review aims to gather the most updated available information about research on biotechnological methods to recover chitin from crustacean waste, studied during the past 10 years, focussing on conditions applied to deproteinization (DP) and demineralization (DM), particularly on bioprocessing times and microbial species.
