Phosphorus, nitrogen, and carbon contents of macrophytes in lakes lateral to a tropical river (Paranapanema River, São Paulo, Brazil) Conteúdos de fósforo, nitrogênio e carbono de macrófitas em lagoas laterais a um rio tropical (Rio Paranapanema, São Paulo, Brasil)

open access: yesActa Limnologica Brasiliensia, 2010
AIM: The aim of this paper was to determine the phosphorus, nitrogen, and carbon contents of aquatic macrophyte species during two periods of the year in the land-water transition zone of three lakes lateral to the Paranapanema River (São Paulo); METHODS:

Natural events of anoxia and low respiration index in oligotrophic lakes of the Atlantic Tropical Forest [PDF]

open access: yesBiogeosciences, 2012
Hypoxia is a well-recognized condition reducing biodiversity and increasing greenhouse gas emissions in aquatic ecosystems, especially under warmer temperatures of tropical waters.

Life History of \u3ci\u3eMesovelia Mulsanti\u3c/i\u3e (Hemiptera: Mesoveliidae) in Southern Illinois [PDF]

open access: yes, 2017
The life history of Mesovelia mulsanti was studied during 1983-1986. This species was apparently trivoltine with a partial 4th generation at the end of the year. It overwintered as eggs. First ins tars appeared in mid-April followed by marked overlapping

Profundal benthic invertebrates in an oligotrophic tropical lake: different strategies for coping with anoxia

open access: yesJournal of Limnology, 2014
The deep benthic communities of tropical lakes are poorly understood with respect to their composition, abundance, biomass and regulatory factors. Whereas the hypolimnia of temperate oligotrophic lakes remain oxygenated, the higher temperatures in ...

Lacustrine mollusc radiations in the Lake Malawi Basin : experiments in a natural laboratory for evolution [PDF]

open access: yes, 2012
In terminal Pliocene-early Pleistocene times, part of the Malawi Basin was occupied by paleo-lake Chiwondo. Molluscan biostratigraphy situates this freshwater lake either in the East African wet phase between 2.7-2.4 Ma or that of 2.0-1.8 Ma.

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Drivers for ecosystem respiration during the drawdown period in Dongting Lake, China

open access: yesFrontiers in Environmental Science, 2023
Global lakes play an active role in releasing carbon into the atmosphere. However, previous research was less focused on shallow tropical and sub-tropical lakes, especially ecosystem respiration during the drawdown period.
