From the early Miocene El Cien Formation, Baja California Sur, Mexico, a new Tapirira species is described. Among the diagnostic features that relate T. peninsularis Martínez-Cabrera & Cevallos-Ferriz sp. nov. with extant species of the genus are libriform septate fibers, radial canals with 2–4 layers of epithelial cells, and scanty paratracheal to vasicentric axial parenchyma. In order to establish similarity between wood of T. peninsularis and fossil and extant species of the genus, cluster and principal component analyses were carried out. Numerical analyses support that Tapirira peninsularis is distinct from other extant and fossil species of the genus. Quantitative characters like frequency of radial canals, diameter of fibres, vessel element lumen, and height and width of the rays with radial canals are important in distinguishing between these taxa. Though these wood characters are quantitative, they also have been useful in the recognition of two subgenera within the genus. Recognition of this new species, along with the fossil record of the group, and a phytogeographic analysis suggest a low latitude North American origin for the genus, and a subsequent introduction to southern latitudes.

History Of

Three types of fossil woods with similarities to the Leguminosae are described, Mimosoxylon tenax (Felix) Müller-Stoll ' Mädel, Bajacalijomioxylon cienense Cevallos-Ferriz ' Barajas-Morales, gen. et sp. nov., and Copaijeroxylon matanzensis Cevallos-Ferriz ' Barajas-Morales, sp. nov. These woods are from the EI Cien Formation in Baja California Sur, Mexico, which is dated as Zemorrian-Saucesian, i.e., late Oligocene–early Miocene. Although two of the names of the fossil woods suggest affinity with a particular extant taxon, differences in some quantitative and qualitative features preclude their identification with a single extant taxon. The similarity among wood of some groups of extant Leguminosae and limited knowledge of character variability in woods of this family explains this taxonomie uncertainty. These fossil woods from Baja California underscore the need for an extensive systematic study of the wood anatomy of Leguminosae, add to the poorly known plant history of the Peninsula, suggest a tropical South American influence in the fossil flora of Baja Califomia, and indicate that the climate during the Zemorrian- Saucesian was different from the xeric conditions that prevail today in the area.

La pesca deportiva es una actividad turística que genera una considerable derrama económica para el estado de Baja California Sur (BCS). En este sentido, es importante conocer las características de los pescadores recreacionales, para generar estrategias de manejo apropiadas a los contextos locales. Este estudio caracterizó la actividad y el perfil del pescador deportivo que visita BCS, además de identificar su percepción sobre la técnica de captura y liberación, la cual favorece la conservación de los recursos. Con un total de 922 encuestas en tres localidades, Cabo San Lucas, Los Barriles-Buenavista e Isla Cerralvo, se identificó que más del 80 % de los pescadores deportivos que acuden a BSC son de origen extranjero (principalmente de EUA), que el nivel de experiencia de pesca que predomina es el intermedio y que tienen una percepción favorable de la práctica de capturar y liberar; sin embargo, en éstas y en otras características (e.g. ingreso, edad, horas de traslado, entre otras) las proporciones entre las localidades son diferentes. Considerando la información de carácter socioeconómico, se caracterizaron dos tipos de pescador deportivo: el de ocasión y el exclusivo. Además, se identificó que el género femenino es un segmento de mercado poco atendido, el cual tiene potencial de crecimiento.
