“…According to pioneer studies (Brooks and Dodson, 1965), small-sized zooplankton would dominate when planktivorous fish are abundant, and large-sized plankton when invertebrate predators predominate (Dodson, 1974), as summarized by Lampert and Sommer (2007;in Fig. 6.33).…”

INTRODUCTIONLong-term studies are essential for understanding ecological processes such as the influence of stressors and are basic for modeling, but are few in number because of their inherent difficulties, including costs (Jackson and Füreder, 2006;Maberly and Elliott, 2012). In particular, long-term studies of zooplankton can reveal the influence of past factors, including management decisions (Hambright, 2008). Some causes of changes in the zooplankton that are perceptible over a longer period include alterations of abiotic factors or predator invasion (Yan et al., 2008).The factors that affect the diversity and size of zooplankton species are intriguing issues, but still subject to controversy. From the classic paper by Brooks and Dodson (1965) to recent studies, several factors have been contemplated, and temperature has emerged as the preponderant factor for explaining latitudinal differences in zooplankton body size (Gillooly and Dodson, 2000). Gillooly and Dodson compared more than 1100 lakes located between 81°N and 77°S latitude, and found that the size variation of cladoceran species was related to latitude, with smaller sizes in the tropics and the Arctic and a greater difference between the tropics and the temperate zone. According to these authors, the highest mean sizes were observed between 6°C and 8°C, declining at higher or lower temperatures. Havens et al. (2015), comparing 122 lakes located from 6° to 74°N and from 19° to 21°S, showed a relationship between size (as weight) of cladocerans and cyclopoid copepods and temperature. In contrast, Iglesias et al. (2011) suggested that predation by fish is the major factor explaining the smaller size of zooplankton in warm lakes. Hart and Bychek (2011), in their extensive review of the many factors that could potentially influence zooplankton size, addressed extrinsic factors such as temperature, food and predation, amongst others, besides intrinsic ones. The authors concluded, however, that although a general pattern may occur, different results can arise from distinct ecosystems.J.

“…Several species of Daphnia are recognized as efficient herbivores (Dodson, 1974). The negative correlation between D. laevis and chlorophyll-a emphasizes the herbivory pressure of this cladoceran on the phytoplankton community.…”

Fluctuations of the population of Daphnia laevis Birge 1878: a six-year study in a tropical lake

et al. 2012

The fluctuation of the population of Daphnia laevis in Lake Jacaré (Middle River Doce, Minas Gerais) was monitored monthly (at one point in the limnetic region) for six years (2002)(2003)(2004)(2005)(2006)(2007) as part of the Program of Long-Term Ecological Research (LTER/UFMG). The following parameters were also monitored: water temperature, pH, electrical conductivity, dissolved oxygen, chlorophyll a, total phosphorus, phosphate, total nitrogen, nitrate, nitrite, ammonia, and densities of Chaoborus and ephippia of Daphnia laevis in the sediment.

“…Thus, the larger zooplankters were more abundant in fish-present lakes. The presence in the systems of Chaoborus larvae, which are selective predators able to structure the zooplankton community (Dodson 1974;Fedorenko 1975a;Pope and Carter 1975;Neill 1981), could explain the observed patterns. Thus, brook trout was not the sole predator of zooplankton because Chaoborus larvae were important planktivores in fishless lakes.…”

Les conditions physico-chimiques de ces lacs sont favorables à la survie des poissons et plusieurs d'entre eux ont déjà été ensemencés avec succès au profit de la pêche sportive. Toutefois, l'influence de cette activité sur l'intégrité biotique et la diversité biologique demeure inconnue. L'absence de poisson au sommet de la chaîne trophique peut influencer l'abondance des organismes, mais aussi la diversité et les assemblages d'espèces. De plus, l'importance des lacs sans poissons au sein de l'écosystème boréal est encore inconnue. Par exemple, les lacs sans poissons pourraient être un élément important impliqué dans la conservation de la population de l'est du
