Abstract: En su ruta migratoria, numerosas aves llegan a los humedales Pisco; sin embargo, se conoce poco de ellas, así como del humedal de Caucato. Se estudió el ensamble, la variación de la abundancia y diversidad de la avifauna. Se realizaron conteos mensuales por hábitat empleando transectos de 100 m de largo y 20 metros de ancho en ambos lados. Para el ensamble de aves se usó la Clasificación de las especies de aves de América del Sur. La diversidad de Shannon-Wiener y la equitatividad de Pielou se calcularon con e… Show more

A population estimation of Wilson’s Phalaropes was conducted in the Confinada Lagoon of the inner bay of Lake Titicaca in the city of Puno between August and May of 2016/2017, 2017/2018 and 2018/2019. We employed the quadrat method of population estimation with three repetitions using 10×50 mm binoculars between 06:00 and 08:00 h. We recorded population fluctuations in August and September (immigration season) and April and May (emigration season). We counted a maximum population of 112,000 Wilson’s Phalaropes during the immigration season, and then in the emigration season. During their stay of approximately 8 months, the birds feed on water fleas, insects and detritus amounted to 146,496 t. The inner bay of Lake Titicaca is an important aquatic habitat for these migratory birds, which has a positive impact on the contribution to the decontamination of the lake.

Wetlands are crucial hydrological features that provide benefits, including ecosystem services and habitat conservation, protection from flooding associated with sea level rise and extreme events, water storage and treatment, recreation, and aesthetics, among others. Peru is one of the few countries in Latin America that has not developed a national wetland inventory. While this can in part be attributed to the limited availability of peer-reviewed publications in the English literature, a larger quantity of Peruvian wetland-related publications are available in Spanish, and are less accessible to the global population. In this paper, we developed an extensive review and synthesis of the Spanish literature, including university theses, peer-reviewed articles, and government reports. Our report focuses on evaluating the state of the art of Peruvian wetlands in terms of temporal evolution, geographical distribution, vested institutions, research topics (e.g., water quality, fauna, flora, microorganisms, etc.), and advances toward the conservation of wetlands. The analysis identified 274 wetland-related publications in Spanish (188 theses, 83 peer-reviewed, and 6 government reports) and a temporal increase in dissemination over the past two decades. The reports encompassed 161 distinct wetlands distributed nationwide; however, most of the investigations focused on only a few wetland bodies with a disproportionate concentration in just three administrative regions. This reveals that wetland-related research is unevenly distributed in Peru, and highlights a need to extend this knowledge to underrepresented systems and regions. Although Peru ranks third in South America for protected (Ramsar) wetland areas, case studies have revealed that wetlands in the country are vulnerable to human activities. Recent national legislation established in 2021 should help to address this challenge, as before this time, there was a more decentralized approach, whereby each administrative region held responsibility for the protection of their own wetlands. Collective findings indicate that research activity should be increased nationally in order to better understand the function and benefits of wetlands throughout Peru, in addition to the continued development and enforcement of regulations designed to protect these valuable ecosystems. Finally, since a national Peruvian wetland inventory is urgently needed, this analysis provides a baseline for this development of, as well as identifying gaps in, knowledge needed for appropriate national representation.

Los humedales brindan diversos servicios ecosistémicos al ser humano y son lugares de refugio de la avifauna silvestre. Se caracterizó la comunidad de aves acuáticas del humedal de Caucato a partir del ensamble, la variación de la abundancia y variación de la diversidad. Se realizaron conteos de aves en los hábitats denominados orilla de playa, espejo de agua, orilla de laguna, gramadal, juncal, campo de cultivo y matorral; la identificación se realizó mediante métodos convencionales. El ensamble se determinó a partir de la clasificación de las especies de aves de América del Sur; la variación de la abundancia relativa fue determinada mediante el índice de abundancia relativa espacial (IARE); se calculó el índice de diversidad de Shannon-Wiener (H’) y la equitatividad de Pielou (J) mediante el software PAST 3.24. Se identificó 55 especies de aves, agrupadas en 19 familias, de las cuales, las familias Scolopacidae, Laridae y Ardeidae agrupan el mayor número de especies. La familia Laridae (962 individuos) y la especie Gallinula galeata (545 individuos) fueron las más abundantes; esta última tiene el mayor índice de abundancia relativa (IARE = 38.93 ind/100 m). La población experimentó una disminución entre marzo y abril para luego aumentar de manera progresiva. La Orilla de laguna presenta los mayores índices de diversidad y equidad (H´OL=3.25; JOL=0.91). Se concluye que, el ensamble de aves en el humedal de Caucato es mayor respecto a otros humedales cercanos; la variación en la abundancia está influenciada por las migraciones de las aves boreales y australes; Gallinula galeata es la especie con mayor abundancia y la Orilla de playa el hábitat con mayor diversidad.
