Macroalgas submareales de la bahía de Todos Santos, Baja California, México
Aguilar-Rosas, Raúl;Aguilar-Rosas, Luis E.;ávila Serrano, Guillermo E.;González Yajimovich, óscar;Becerril Bobadilla, Francisco;
Revista mexicana de biodiversidad , 2010,
Abstract: in order to identify and characterize the species composition of the subtidal zone of the todos santos bay, baja california, mexico, benthic marine macroalgae were sampled at 7 sites from 1995 to 2000. as a result of 25 scuba at derds for the study area, of which faucheocolax attenuata setchell and r.l moe minium parvum are new to the marine flora of pacific mexico. we include a research that consider the macroalpths between 3 and 33 m we found a total of 150 species of macroalgae for the study area, of which 10 are chlorophyta, 26 phaeophyta and 114 rhodophyta; 47 species represent new recogae in the todos santos bay and a discussion on the composition of species found, its vertical distribution and reproduction, particularly the species epiphytes and parasites present in the study area.
Effects of El Ni o on beds of Ulva lactuca along the northwest coast of the Gulf of California, Mexico
I. Pacheco-Ruíz,F. Becerril-Bobadilla,J. A. Zertuche-González,A. Chee Barragán
Geofísica internacional , 2003,
Abstract: The effect of El Ni o 1997-1998 on the biomass and size of beds of the green alga Ulva lactuca L., along the northwest coast of the Gulf of California across the Canal de Ballenas, was evaluated in May 1998 and compared with May 1995, 1996 and 2000. The El Ni o event (97-98) had a significant negative effect on size and biomass. The percent cover area was reduced by 70%, and biomass by 80%, with respect to previous years. A complete recovery was observed in 2000. Growth of the algae was studied under controlled conditions in the laboratory. No significant effect of irradiance was detected, but temperature did have a significant effect on growth. Optimum growth was found at 18°C. Temperatures of 14°, 22° and 26°C caused reduced growth. A temperature of 30°C was lethal to U. lactuca.

Topological equisingularity of function germs with 1-dimensional critical set
Javier Fernandez de Bobadilla
Mathematics , 2006,
Abstract: We focus on topological equisingularity of families of holomorphic function germs with 1-dimensional critical set. We introduce the notion of equisingularity at the critical set and prove that any family which is equisingular at the critical set is topologically equisingular. We show that if a family of germs with 1-dimensional critical set has constant generic Le numbers then it is equisingular at the critical set, and hence topologically equisingular (answering a question of D. Massey). We use this to modify the definition of singularity stem present in the literature, introducing and characterising topological stems (being this concept closely related with Arnold's series of singularities). We provide another sufficient condition for topological equisingularity for families whose reduced critical set is deformed flatly. Finally we study how the critical set can be deformed in a topologically equisingular family and provide examples of topologically equisingular families whose critical set is a non-flat deformation with singular special fibre and smooth generic fibre.
On homotopy types of complements of analytic sets and Milnor fibres
Javier Fernandez de Bobadilla
Mathematics , 2009,
Abstract: We prove that for any germ of complex analytic set in $\CC^n$ there exists a hypersurface singularity whose Milnor fibration has trivial geometric monodromy and fibre homotopic to the complement of the germ of complex analytic set. As an application we show an example of a quasi-homogeneous hypersurface singularity, with trivial geometric monodromy and simply connected and non-formal Milnor fibre.
