Cronología de tiburones del Parque Nacional Cabo Pulmo, Golfo de California; registros bibliográficos y de campo El arrecife de Cabo Pulmo en el suroeste del Golfo de California, México (23° 26´ N, 109° 25´ W), es considerado una de las áreas protegidas más exitosas del Pacífico americano, ya que durante este siglo han habido aumentos en abundancia y biomasa de peces carnívoros residentes (pargos, cabrillas, jureles, tiburones, etc.). Ello se debe al régimen de no pesca y el buen estado de conservación que le permiten mantener niveles altos de productividad primaria y secundaria. El aumento en el flujo de materia y energía ha provocado la llegada de especies de niveles tróficos altos como los tiburones, los cuales son más frecuentes y representan una atracción turística local. El objetivo del presente trabajo es presentar una cronología de la aparición de las distintas especies de tiburones en Cabo Pulmo, con base en bibliografia, trabajo de campo y consultas con residentes locales, guías de buceo y especialistas que han visitado la zona en los últimos 15 años. Los resultados muestran que en el arrecife de Cabo Pulmo se han registrado 11 especies de tiburones de 9 géneros y 6 familias; ocho de estas fueron anotadas en diversas fuentes bibliográficas; aquí se cita por primera vez la ocurrencia de tres más (Sphyrna lewini, Gynglymostoma cirratum y Carcharhinus longimanus). La llegada de estas especies a la zona arrecifal pudiera ser indicativo de un buen estado del ecosistema local, por ello es de esperarse que los próximos años se registre un número mayor de especies de tiburones, o de su biomasa.

The crown of thorns (CoTS; Acanthaster cf. solaris) have not been reported as an actual threat to reefs in the Gulf of California; however, in the Espiritu Santo Archipelago National Park, we have evidenced massive predation over scleractinian corals. Its abundance is now over outbreaks threshold value and it is higher than historical records

Infiltration Recharge

Quantitative assessment of the amount of renewable resources allows their evaluation, valorization and protection in terms of the possibility of their environmental management under climate change conditions. The aim of the study was to determine the amount of renewable resources in the Middle Vistula valley, in the region of the Kampinos National Park, central Poland. The amount of renewable resources was calculated on a hydrodynamical model for three variants, as the average, the lowest and the highest infiltration recharge rate for a specified period of 1999–2013. The modelling research was conducted in a strongly differentiated hydrogeological valley unit, in which several geomorphological units could be delineated: the floodplain, over-flood terraces and the plain area. The hydrodynamic modelling results were verified by comparing the obtained data with both the amount of drainage in the valley zone and the underground streamflow. The assessment of renewable groundwater resources in three distinctive variants was the basis for calculating the groundwater footprints, defined as a quantitative assessment of the groundwater use in climate change conditions.

This study constitutes a preliminary assessment of the abundance and species richness of sponges living on the brown seaweedSargassumspp. from the southern Gulf of California (Mexico). The diversity and abundance of sponges associated withSargassumwas investigated from November 2006 to November 2007. In addition, it was examined whether temporal variations in the abundance of associations were influenced by changes in size and density ofSargassumas well as environmental factors such as water temperature and salinity. Twelve sponge species (4 Haplosclerida, 3 Poecilosclerida, 4 Dictyoceratida and 1 Clathrinida) were found growing epiphytically on the lower portions ofSargassumplants and the most frequent species wereCallyspongia californicaandHaliclona turquoisia(38% and 27%, respectively). The abundance of associations showed significant temporal and spatial variations, being higher from June to November (postSargassumgrowth period), at depths from 0.5–2.5 m. The number of sponge species m−2(both epiphytic and non-epiphytic) inside the seaweed bed was 4.8 species m−2, while outside it, the absence of hard substrate for attachment severely restricted the number of sponges. These results suggest thatSargassumprovide substratum and habitat for the sponge community from this region, and that their seasonal growth patterns may influence the abundance and diversity of the associations.

Migratory Movements

Current literature considers that Nasolamia velox has a limited distribution along the coastline of the Eastern Pacific with sporadic sightings in the Galapagos Archipelago. This study provides evidence of the occurrence of this species at the Revillagigedo Archipelago (18°99′186″N 112°08′44″W), Mexico, using acoustic telemetry and videos taken from 2014 to 2016. We report here movements from a coastal location (National Park Cabo Pulmo) to a group of oceanic islands (Revillagigedo Archipelago) by one single individual, supporting the idea of the potential connectivity of sharks between the Gulf of California and the Revillagigedo Archipelago. This report extends the known distribution of N. velox to 400 km off the mainland coast of the Americas, thereby increasing the knowledge of the distribution of a species commonly reported in fishery landings of the Eastern Pacific.
