Diego F. Cisneros-Heredia Co-Editor, Avances en Ciencias e Ingenierías Universidad San Francisco de Quito “Usted forma parte integral de la naturaleza; su destino está estrechamente unido a la diversidad biológica, a la gran variedad de los otros animales y plantas, al lugar donde viven y a los entornos que los rodean en todo el mundo. Usted depende de esta diversidad de la vida para obtener el alimento, el combustible, las medicinas y los demás elementos esenciales sin los que no podría vivir. Sin embargo, esta rica diversidad se está perdiendo a una gran velocidad debido a la actividad humana. Esto nos empobrece y mina la capacidad de los sistemas de vida, de los que dependemos, para resistir a las crecientes amenazas como, por ejemplo, el cambio climático. JOTA JOTA Las Naciones Unidas proclamaron 2010 el Año Internacional de la Diversidad Biológica y la gente de todo el mundo está trabajando para salvaguardar esta riqueza natural insustituible y para reducir su pérdida. Es vital para el bienestar humano presente y futuro. Necesitamos hacer más. Ahora es el momento de actuar. El Año Internacional de la Diversidad Biológica es una oportunidad única para aumentar la comprensión de la función vital que tiene la biodiversidad en el mantenimiento de la vida en la Tierra”. 2010 Año Internacional de la Biodiversidad http://www.cbd.int/ SECCIÓN B: CIENCIAS BIOLÓGICAS Y AMBIENTALES Range extension for the barrel shrimp Gnathophyllum panamense (Malacostraca: Decapoda: Pleocyemata: Caridea: Gnathophyllidae) along the Ecuadorian coast B1–B2 K.

  • About the Book the Format Acknowledgments
    About the Book For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes. Having reached the age when I could retire whenever I wanted to, I no longer needed be so concerned with the publish or perish paradigm. In keeping with the sharing nature of bryologists, and the need to educate the non-bryologists about the nature and role of bryophytes in the ecosystem, it seemed my personal goals could best be accomplished by publishing online. This has several advantages for me. I can choose the format I want, I can include lots of color images, and I can post chapters or parts of chapters as I complete them and update later if I find it important. Throughout the book I have posed questions. I have even attempt to offer hypotheses for many of these. It is my hope that these questions and hypotheses will inspire students of all ages to attempt to answer these. Some are simple and could even be done by elementary school children. Others are suitable for undergraduate projects. And some will take lifelong work or a large team of researchers around the world. Have fun with them! The Format The decision to publish Bryophyte Ecology as an ebook occurred after I had a publisher, and I am sure I have not thought of all the complexities of publishing as I complete things, rather than in the order of the planned organization.

  • Ecological Functions of Neotropical Amphibians and Reptiles: a Review
    Univ. Sci. 2015, Vol. 20 (2): 229-245 doi: 10.11144/Javeriana.SC20-2.efna Freely available on line REVIEW ARTICLE Ecological functions of neotropical amphibians and reptiles: a review Cortés-Gomez AM1, Ruiz-Agudelo CA2 , Valencia-Aguilar A3, Ladle RJ4 Abstract Amphibians and reptiles (herps) are the most abundant and diverse vertebrate taxa in tropical ecosystems. Nevertheless, little is known about their role in maintaining and regulating ecosystem functions and, by extension, their potential value for supporting ecosystem services. Here, we review research on the ecological functions of Neotropical herps, in different sources (the bibliographic databases, book chapters, etc.). A total of 167 Neotropical herpetology studies published over the last four decades (1970 to 2014) were reviewed, providing information on more than 100 species that contribute to at least five categories of ecological functions: i) nutrient cycling; ii) bioturbation; iii) pollination; iv) seed dispersal, and; v) energy flow through ecosystems. We emphasize the need to expand the knowledge about ecological functions in Neotropical ecosystems and the mechanisms behind these, through the study of functional traits and analysis of ecological processes. Many of these functions provide key ecosystem services, such as biological pest control, seed dispersal and water quality. By knowing and understanding the functions that perform the herps in ecosystems, management plans for cultural landscapes, restoration or recovery projects of landscapes that involve aquatic and terrestrial systems, development of comprehensive plans and detailed conservation of species and ecosystems may be structured in a more appropriate way. Besides information gaps identified in this review, this contribution explores these issues in terms of better understanding of key questions in the study of ecosystem services and biodiversity and, also, of how these services are generated.

E-mail: [email protected] Abstract We evaluate the monophyly and phylogenetic relationships of the Pristimantis leptolophus species group and describe its external morphology, osteology, and some myological characteristics. We also compare the P. leptolophus species group to other related species groups. The P. leptolophus group is not monophyletic due to the inclusion of P. acatallelus, for- merly believed to be part of the P. devillei group. The revised P. leptolophus group is composed of nine named species and six unnamed species. Based on our results, we recognize a new species group, the P. boulengeri species group, com- posed of eight species, many of which were previously assigned to the P. lacrimosus species group. Key words: Craugastoridae, myology, osteology, phylogeny, systematics, terrarana Introduction With 494 species of Neotropical, direct-developing frogs (Frost, 2016), Pristimantis Jiménez de La Espada, 1870 is the richest genus of vertebrates.

Competition and distribution model predictions vary based on dominance hierarchies, but most assume differences in dominance are constant across habitats. More recent evidence suggests dominance and competitive advantages may vary based on habitat. We quantified dominance interactions between two species of sharks Carcharhinus amblyrhynchos and Carcharhinus melanopterus, across two different habitats, fore reef and back reef, at a remote Pacific atoll. We used Baited Remote Underwater Video (BRUV) to observe dominance behaviors and quantified the number of aggressive interactions or bites to the BRUVs from either species, both separately and in the presence of one another. Blacktip reef sharks were the most abundant species in either habitat, and there was significant negative correlation between their relative abundance, bites on BRUVs, and the number of grey reef sharks. Although this trend was found in both habitats, the decline in blacktip abundance with grey reef shark presence was far more pronounced in fore reef habitats. We show that the presence of one shark species may limit the feeding opportunities of another, but the extent of this relationship is habitat specific. Future competition models should consider habitat-specific dominance or competitive interactions.

    Plant diversity and vegetation of the Andean Páramo Diversidad de plantas y vegetación del Páramo Andino By Gwendolyn Peyre A thesis submitted for the degree of Doctor from the University of Barcelona and Aarhus University University of Barcelona, Faculty of Biology, PhD Program Biodiversity Aarhus University, Institute of Bioscience, PhD Program Bioscience Supervisors: Dr. Xavier Font, Dr. Henrik Balslev Tutor: Dr. Xavier Font March, 2015 Aux peuples andins Summary The páramo is a high mountain ecosystem that includes all natural habitats located between the montane treeline and the permanent snowline in the humid northern Andes. Given its recent origin and continental insularity among tropical lowlands, the páramo evolved as a biodiversity hotspot, with a vascular flora of more than 3400 species and high endemism. Moreover, the páramo provides many ecosystem services for human populations, essentially water supply and carbon storage. Anthropogenic activities, mostly agriculture and burning- grazing practices, as well as climate change are major threats for the páramo’s integrity. Consequently, further scientific research and conservation strategies must be oriented towards this unique region. Botanical and ecological knowledge on the páramo is extensive but geographically heterogeneous. Moreover, most research studies and management strategies are carried out at local to national scale and given the vast extension of the páramo, regional studies are also needed. The principal limitation for regional páramo studies is the lack of a substantial source of good quality botanical data covering the entire region and freely accessible. To meet the needs for a regional data source, we created VegPáramo, a floristic and vegetation database containing 3000 vegetation plots sampled with the phytosociological method throughout the páramo region and proceeding from the existing literature and our fieldwork (Chapter 1).
