Water Passage

It is not surprising that prior to the construction of the Panama Canal, Nicaragua was considered of strategic importance to the world's major sea powers. Together the Río San Juan and Lake Nicaragua provide a water passage from the Caribbean Sea to within 20 kilometers of the Pacific Ocean (see map). In addition to its obvious inter-oceanic canal potential, this water passage was primarily useful for hundreds of years as an alternate route for the pirate-threatened Central American colonial commerce.A remarkable number of historical and geographical misconceptions have appeared in the literature concerning this river. The recent publication of the seventeen-volume Colección Somoza containing documents relating to the history of Nicaragua from 1503 to 1550 does much to clarify this period of exploration and navigation.

Philoscia Muscorum

Examination of a small collection of Oniscidea from Costa Rica revealed the presence of two species new to science (Ischioscia martinae sp.nov. and Scleropactes talamancensis sp.nov.). Further specimens from the collection of the United States National Museum were reexamined to reconsider the status of Philoscia muscorum (Scopoli, 1793) and Ischioscia variegata (Dollfus, 1893), both of which have been reported from Costa Rica. The specimens belong to two new species (Ischioscia muelleri sp.nov. and Ischioscia elongata sp.nov.). Redescriptions of Ligia baudiniana Milne Edwards, 1840 from the shores of both the Caribbean Sea and the Pacific Ocean and the type material of Ischioscia variegata (Dollfus, 1893) from Venezuela are also presented.

Significant Figures

For centuries Europeans were fascinated by rumours and legends of the wealth and wonders of the Orient and by stories of the supposed existence there of realms free from all those tiresome taboos and restrictions that prevailed in the West. Long before the arrival of Vasco da Gama, renegades were serving the Mongols in Iran and Marco Polo had been in the entourage of the Grand Khan himself. The Portuguese pioneers were disconcerted to encounter in 1501 a certain Benvenuto de Abano who had spent the previous twenty-five years sailing the seas of Asia, and his contemporary, the Muslim Khoja Safar Salmâni, an erstwhile Genoese or Albanian. But this was nothing compared with the flow that followed western penetration of the maritime economy of the East, scattering European adventurers and outlaws throughout the Orient anywhere from the shores of the Persian Gulf to those of the Pacific Ocean. And very soon these hopefuls were joined by European pirates, some working from ports in their mother countries, some from the Caribbean and North America, and some from bases in the Indian Ocean, of which Madagascar was, according to taste, the most celebrated or the most notorious. Such men, frequently of remarkable skills and fearsome abilities, exercised a considerable influence on the maritime history of the East in the early modern centuries, and it is with the origins, aspirations and activities of these elusive—indeed often anonymous—but nevertheless highly significant figures that this paper is concerned.

Colombia has approximately 379,954 hectares of mangrove forests distributed along the Pacific Ocean and the Caribbean Sea coasts. Such forests are experiencing the highest annual rate of loss recorded in South America and, in the last three decades, approximately 40,000 hectares have been greatly affected by natural and, especially, human impacts. This study determined, by the use of Landsat multispectral satellite images, the evolution of three mangrove forests located in the Colombian Caribbean Sea: Malloquín, Totumo, and La Virgen swamps. Mangrove forest at Mallorquín Swamp recorded a loss of 15 ha in the period of 1985–2018, associated with alterations in forest hydrology, illegal logging, urban growth, and coastal erosion. Totumo Swamp lost 301 ha in the period 1985–2018 associated with changes in hydrological conditions, illegal logging, and increased agricultural and livestock uses. La Virgen Swamp presented a loss of 31 ha in the period of 2013–2018 that was linked to the construction of a roadway, alterations of hydrological conditions, illegal logging, and soil urbanization, mainly for tourist purposes. Although Colombian legislation has made efforts to protect mangrove ecosystems, human activities are the main cause of mangrove degradation, and thus it is mandatory for the local population to understand the value of the ecosystem services provided by mangroves.

The habitat formed by the Callogorgia species, with their abundance and colony sizes, provides an important refuge for a variety of brittle stars which are recognized as the epibionts of octocorals in both shallow and deep environments. In such a relationship, ophiurans benefit directly from being elevated because they facilitate their feeding by suspension, while octocorals do not seem to benefit or be harmed. During three different expeditions developed in the Colombian Pacific from 2012 to 2013 and in the Caribbean Sea during 1998 and 2012 by the INVEMAR - Marine and Coastal Research institute, different samplings were carried out on soft bottoms through trawls with an epibenthic net. For the Pacific Ocean, 33 fragments of the octocoral Callogorgia cf. galapagensis Cairns, 2018 with 178 specimens of the ophiuroid Astrodia cf. excavata (Lütken and Mortensen, 1899) were found in two stations at depths 530 and 668 m. Considering the abundance of A. cf excavata, other biological characters such as size, presence of mature gonads, and evidence of arm regeneration were also detailed. In contrast, in the Caribbean Sea, Callogorgia gracilis (Milne Edwards and Haime, 1857) was found with ophiuroids belonging to the genera Asteroschema and Ophiomitra. The octocoral Callogorgia americana (Cairns and Bayer, 2002) was also found, but without associated brittle stars. These findings constituted the first specific association reported in the Eastern Tropical Pacific, and new relationships for the Caribbean Sea. This further reflected a possible specific association between the Callogorgia and Astrodia species that needed to be further explored. Thus, the Callogorgia species and the brittle star A. cf. excavata represented new records for the Colombian Pacific Ocean and the southern Caribbean Sea.

Relationships between animals and their associated microbiota are dependent on both the evolutionary history of the host and on the environment. The majority of studies tend to focus on either one of these factors but rarely consider how both determine the community composition of the associated microbiota. One ‘natural experiment’ to test how evolutionary history, shared environments, and the interaction between these factors drive community composition is to compare geminate species pairs. Echinoids separated by the Isthmus of Panama are suitable for this comparison due to their known evolutionary history and differences in the oceanographic characteristics of the Caribbean Sea and the Pacific Ocean. By comparing the bacterial communities of the eggs of Echinometra and Diadema geminate species pairs, we show that each pair of geminate species associates with a distinct bacterial community in a pattern consistent with phylosymbiosis, and that the interaction between the evolutionary history of the host and the environment best explains differences in these communities. Moreover, we found that the relative abundance of particular bacterial taxa differed considerably between the 2 bodies of water and that the 2 Caribbean Echinometra species were dominated by unclassified bacterial taxa within the phototrophic Oxyphotobacteria. Taken together, data presented here support the hypothesis that the bacterial communities associated with geminate species are another characteristic of these species that have diverged in ~2.8 million years of isolation.

The late Miocene Gatun Formation of northern Panama contains a highly diverse and well sampled fossil marine assemblage that occupied a shallow-water embayment close to a purported connection between the Pacific and Atlantic (Caribbean) oceans. However, the diverse chondrichthyan fauna has been poorly documented. Based on recent field discoveries and further analysis of existing collections, the chondrichthyan fauna from this unit comprises at least 26 taxa, of which four species are extinct today. The remaining portion of the total chondrichthyan biodiversity has affinities with modern taxa and is therefore comprised of long-lived species. Based on known records of the modern geographic distribution range of the Gatun chondrichthyans, the fauna has mixed biogeographic affinities suggesting that around 10 million yr ago, a connection likely occurred between the Pacific Ocean and the Caribbean Sea. Given the known habitat preferences for modern chondrichthyans, the Gatun fauna was primarily adapted to shallow waters within the neritic zone. Finally, comparisons of Gatun dental measurements with other faunas suggest that many of the taxa have an abundance of small individuals, in agreement with previous studies that proposed this area as a paleonursery habitat for the species Carcharocles megalodon.

The announcement of Panama as host of World Youth Day in 2019, turned out to be a great surprise for the whole world. For the fi rst time such a small country, has hosted a global event. Panamá is known primarily from the Panama Canal and the Panamanian aff air called Panama. But speaking in these two contexts is very hurtful, because it is a country richly diverse, and the Church here has a unique, unique face. Catholic missions are included in the history of Panama from the very beginning. From the beginning of the bishopric in the city of Panamá, through the territorial development of the Church, everything here has a mark of mission. The fi nal element of the article is the presentation of the Church in the Bocas del Toro Territorial Prelature. The prelature is located in the Caribbean Sea and is geographically diff erent from the rest of the country. But this place is an example of a missionary church, and of a church that needs support in its mission. Poles coming to Panama for the next World Youth Day will discover a unique country, and together with the Poles, Panama will be discovered by the whole world.
