A reason for the high diversity of bats in Matanzas may be that Cuba does not possess major geographical barriers such as very tall mountains or deserts. Instead, the island is characterized by its low-lying landscape, with hills that rarely surpass 300 m in height. As a result, bat distribution in Cuba is highly homogeneous. Similar numbers of species are found in all other of Cuba's 15 provinces. This could be a reflection of the area's most recent geological history or less collecting efforts in the rest of Cuba.

Bats are amazing creatures, with amazing adaptations. With their skin-webbed wings, velvety fur, and sharp teeth, bats have probably cruised the Cuban skies in search of food and shelter for a least 33 million years (Eocene-Oligocene), when the island emerged and became available for colonization; although, unfortunately, we only have bat fossils from the last 20 thousand years (2).

The biological diversity and uniqueness of Cuba is a result of the island’s intricate geological history and its long isolation from the mainland. Over 60% of the Cuban landscape is karstic, and nearly 80 % if the submerged platform is counted, indicating a high potential in the availability of caves, crucial shelters that allow high species richness. In fact, this has been correlated by bat researchers (Brunett and Medellin, 2001). Of the 28 known Cuban bats, 15 are strict cave -dwellers, with most others using caves opportunistically (1).

Here is where Matanzas shines. Matanzas harbors today the most extensive subaerial karst region of the entire Cuban archipelago, a potentially very cave-rich region ~65,500 km² wide. Probably, no other province in Cuba has more caves available for bat roosting than Matanzas today. Moreover, this was more strikingly so 10,000 years ago, when the Gulf of Batabanó, south of the western half of Cuba, had the largest potential in the availability of caves for bat roosting anywhere in the Cuban archipelago, competing in the Caribbean only with the Bahama bank. Once the ice of the last glacial maximum melted with the warmer temperatures of the Holocene epoch, sea level rose and inundated most of the Cuban ancient karst plains, drowning about ~13,300 km² of latent cave-rich territory (3), essential for bat life in the island, and likely culling the territory of a few species. Many have postulated this as the reason for the disappearance of several bat species.
Matanzas has played an important role in the study of Cuban bats since at least the XIX century. Four of Cuba's bats Pteronotus parnelli, Pteronotus quadridens, Phyllonycteris poeyi and Tadarida brasiliensis (muscula), were collected and described for the first time from Matanzas, near the coffee plantation Fundador de Canímar. This feat is the work of the German naturalist, Johannes Gundlach.
Gundlach stopped in Cuba on his way to South America and fell in love with the island. I venture to say, he fell in love with Matanzas as well, for he took residence there for nearly the rest of his life. He settled in the lush region near the Canímar River, where he stayed with the Booth family who had plantations there. Gundlach roamed the countryside, especially the Zapata Swamp, and the Canímar River gorge where he observed and collected specimens of mollusks, reptiles, and bats.
It is through the work of the proliferous Johannes Gundlach and Gilberto Silva Taboada that I came to love bats. In 1992, my parents gave me Silva Taboada's Los Murcielagos de Cuba (The Bats of Cuba), which to my delight had a great introduction to the life of Gundlach and his bat research.
Under the auspice of Gundlach and Silva, I studied the bats living in the roof of our schools and nearby caves, amassing a large set of information, with other colleagues, on the bat diversity in the city and nearby caves. This information resulted in over 100 new fossil and modern bat-collecting localities, several publications, and first records for the province of Matanzas.
For example, we (Ricardo Viera and I) reported the new records of the rare and extinct Common vampire bat Desmodus rotundus, Cuban fruit-eating bat Artibeus anthonyi, Peter’s ghost-faced bat Mormoops megalophylla, Greater funnel-eared bat Natalus primus, and Koopman’s pallid bat Antrozous koopmani. In addition, to new records of living Cuban lesser funnel-eared bat Chilonatalus macer, Cuban yellow bat Lasiurus insularis and Pfeiffer’s red bat Lasiurus pfeifferi , and including remote localities in the Zapata Swamp as in the urban Varadero (see publications here, and Viera's here).
Currently, we are finishing a gazetteer on all the known fossil and modern bat localities in the province that can be useful towards entropy modeling for species distribution in the archipelago. We hope to collaborate with all those interested.
More so, the research continues. Some of our findings have been corroborated by Proyecto CUBABAT under the direction of Melissa Connelly, with the collaboration of colleagues in Matanzas. They have recently reported, and photographed, the Cuban fig-eating bat Phyllops falcatus in Varadero, so far only reported there from fossil remains (see citations above), and the Cuban lesser funnel-eared bat Chilonatalus macer, and Pfeiffer’s red bat Lasiurus pfeifferi (M. Connelly, pers. comm.) This project has a great potential, for it disseminates important information on the ecological importance of bats. Additionally, through research, they collect useful data crucial for bat conservation in not only Matanzas but also all of Cuba and the Greater Antilles.
We wish them success!
