“…(2003) found the two macrophytes supported different macroinvertebrate assemblages. Preliminary results from an on‐going study on Lake Chapala (Mexico) also suggest richer and more‐abundant macroinvertebrate communities within the roots of water hyacinth than found in open water or within emergent vegetation stands (Villamagna, 2009).…”

“…To date, there are no published studies that suggest water hyacinth mats significantly affect the bird community or individual species. However, floating patches of water hyacinth in Lake Chapala (Mexico) have provided additional foraging habitat for large wading birds, such as the Great Egret ( Ardea alba L.), Snowy Egret ( Egretta thula Molina), Tri‐colored Heron ( Egretta tricolor Muller) and Great Blue Heron ( Ardea herodias L.) and a direct food source for American Coots ( Fulica americana Gmelin) (Villamagna, 2009).…”

SUMMARY1. Water hyacinth (Eichhornia crassipes) is one of the world's most invasive aquatic plants and is known to cause significant ecological and socio-economic effects. 2. Water hyacinth can alter water clarity and decrease phytoplankton production, dissolved oxygen, nitrogen, phosphorous, heavy metals and concentrations of other contaminants. 3. The effects of water hyacinth on ecological communities appear to be largely nonlinear. Abundance and diversity of aquatic invertebrates generally increase in response to increased habitat heterogeneity and structural complexity provided by water hyacinth but decrease due to decreased phytoplankton (food) availability. 4. Effects of water hyacinth on fish are largely dependent on original community composition and food-web structure. A more diverse and abundant epiphytic invertebrate community may increase fish abundance and diversity, but a decrease in phytoplankton may decrease dissolved oxygen concentrations and planktivorous fish abundance, subsequently affecting higher trophic levels. 5. Little is known about the effects of water hyacinth on waterbird communities; however, increases in macroinvertebrate and fish abundance and diversity suggest a potentially positive interaction with waterbirds when water hyacinth is at moderate density. 6. The socio-economic effects of water hyacinth are dependent on the extent of the invasion, the uses of the impacted waterbody, control methods and the response to control efforts. Ecosystem-level research programmes that simultaneously monitor the effects of water hyacinth on multiple trophic-levels are needed to further our understanding of invasive species.

ResumenEl Lago de Chapala es el más grande de México, es un sitio de interés para la conservación biológica, declarado sitio Ramsar, además de ser reconocido como un Área de Importancia para la Conservación de las Aves (aica 58). Los humedales de Jalisco son de gran importancia para la conservación de las aves; sin embargo, existen pocos estudios, específicamente sobre las aves del Lago de Chapala. En este estudio realizamos el inventario de la comunidad de aves del Puerto Interior Turístico Jocotepec, un parque urbano de la ribera de Chapala. Realizamos el estudio de abril de 2015 a marzo de 2016. Registramos 100 especies de aves pertenecientes a 14 órdenes y 34 familias. El 69% de las aves son residentes, 30% son visitantes de invierno y 1% transitorias. Así mismo, comparamos la riqueza y composición encontrada con otros estudios realizados en el estado de Jalisco. Resalta la presencia de Rallus longirostris, una especie residente y endémica en el centro-occidente de México que presenta los valores de vulnerabilidad más altos. Destacamos la importancia biológica del parque urbano y sugerimos incrementar el número de estudios sobre las aves del Lago de Chapala.Palabras clave: Avifauna, aves acuáticas, parque urbano, humedales, riqueza de especies, sitio Ramsar. AbstractLake Chapala is the largest lake in Mexico. It is an area of interest for biological conservation, designated as a Ramsar site and recognized as an Important Bird Conservation Area for Mexico (aica 58). The wetlands of Jalisco are of high importance for bird conservation; however, there are few studies about the birds of Lake Chapala. We studied bird community in the Puerto Interior Turistico Jocotepec, an urban park of Lake Chapala. We conducted our study from April 2015 to March 2016. We registered 100 bird species of 14 orders and 34 families. Sixty-nine percent of birds are residents, 30% are winter visitors, and 1% are transient. Also, we compared species richness and composition between our results and other studies from the state of Jalisco. We highlight the presence of Rallus longirostris, a resident and endemic species to central-western Mexico, which has the highest vulnerability value. We highlight the biological importance of the urban park and we suggest increasing the number of bird research in Lake Chapala.

“…Those studies analyzed diversity, habitat use, guild structure, and migratory species (see Mellink 2005). However, studies focused on waterbird assemblies in epicontinental lakes are scarce (Ramírez-Bastida 2000; Pineda-López and Arellano-Sanaphre 2010) and largely focused on a single species (Sartor 1989;Munguía et al 2005;Mellink and Riojas-López 2009;Luevano et al 2010;Villamagna et al 2010). Additionally, studies on the community structure of waterbird communities are almost non-existent (see Hernández-Vázquez 2005), and the only study that tested patterns of resource utilization with null models failed in its interpretation (Núñez et al 2008).…”

Foraging guild structure and niche characteristics of waterbirds in an epicontinental lake in Mexico

Background: It was suggested that ecological patterns can be used to infer the nature of ecological processes (i.e., competition) that structure communities. Analysis of patterns of resource partitioning under the classical niche paradigm (competitive niche differentiation in exploiting limited resources) has traditionally been used to understand the structure of communities. On the contrary, neutral theory states that patterns result from neutral processes such as stochasticity and dispersal abilities. Thus, if any ecological process gives rise to a characteristic ecological pattern, the comparative study of patterns with appropriate neutral models may reveal the magnitude of that process. In this study, we analyzed patterns of resource utilization of a waterbird community in Lake Acuitlapilco, an epicontinental lake in central Mexico. In February 2011 to January 2012, we recorded foraging behaviors of waterbird species in two niche dimensions or axes: feeding technique and foraging habitat. The pattern of resource utilization was characterized by niche breath and niche overlap. Results: Results showed that waterbird species in Lake Acuitlapilco were specialists in resource utilization patterns and therefore were vulnerable to fluctuations in resources, particularly feeding habitat. Niche overlaps were generally largest among species belonging to the same guild. To test competition as an ecological process that plays a role in the community structure, observed niche overlaps were compared with niche overlaps generated with null models of communities in the absence of competition using the RA4 randomization algorithm. Habitat and observed bidimensional overlaps were higher than those of randomly generated communities. Conclusions: Our study suggested that other processes can be used to predict resource utilization patterns instead of competition alone, as suggested by neutral theory. Future studies analyzing the mechanisms that structure waterbird communities should include the use of null models to support their conclusions.
