Fluctuations of the population of Daphnia laevis Birge 1878: a six-year study in a tropical lake
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 (2002-2007) as part of the Program of Long-Term Ecological Research (LTER/UFMG).

When a Week Is Not A Week: How Temporal Boundaries Shift Regulatory Focus and Consumer Preference
ABSTRACT Does consumer perception of a sales event change if it falls across a calendar boundary (e.g., next month) versus within the current month, holding objective time constant? We investigate this question in the context of Cyber Monday, the global shopping event occurring the Monday after the U.S. Thanksgiving holiday.

Taxonomic revision of the genus Tzveleviochloa (Poaceae, Aveninae) in India
The taxonomy of Tzveleviochloa in India is revised based on morphological evidence, comprehensive observations of herbarium specimens and field records, and several botanical explorations in the study area. The accepted diversity is increased from two to five species, including two recently described species. The genus is distributed in the Western and

The new species Barleria kulalensis I.Darbysh. & Q.Luke and Dicliptera huriensis I.Darbysh. & Q.Luke are described and illustrated and their extinction risk is assessed provisionally. The former is based on Barleria sp. G of the Flora of Tropical East Africa (FTEA), with recent field observation and collection of this species from the foothills of ...

The origins of ecosystem stability have long intrigued ecologists. Recent theoretical advancements highlight three primary mechanisms driving stability: dominance, asynchrony and averaging. While plant community stability has been extensively studied, our understanding of marine community stability remains limited. Plankton, as key components of marine

Abstract Unsustainable hunting practices can alter population dynamics, driving biodiversity declines, which leads to ‘empty forests’. Understanding hunting behaviour, including motivations for hunting and relationships with market drivers, and access to hunting grounds are important to develop affirmative policies to stem biodiversity loss.
