The flowering patterns of 28 Victorian melliferous (honey-producing) eucalypts were investigated by using long-term observations of highly experienced, commercial apiarists. Frequency, timing, duration and intensity of flowering were determined, as were spatial differences within and among species. Data were obtained by face-to-face interviews with 25 Victorian apiarists, each of whom had operated a minimum of 350 hives for a minimum of 30 years. Flowering frequency ranged from 1 to 7 years, and most species flowered once every 2–4 years. Long-term flowering frequency, timing and duration were reported as constant, although short-term perturbations could occur. Most melliferous species flowered during spring and summer for a period of 3 months or more. Only few species had shorter flowering periods. Information provided by apiarists compared well with available published information (e.g. flowering period reported in field guides) and revealed a reliable, largely untapped source of long-term data, the use of which could benefit many ecological research endeavours.

AbstractIn recent decades, fish ecologists have become increasingly aware of the need for spatially comprehensive sampling. However, a corresponding reflection on the temporal aspects of research has been lacking. We quantified the seasonal timing and extent of freshwater fish research. Since reviewing all prior work was not feasible, we considered two different subsets. First, we compiled the last 30 years of ecological research on juvenile Pacific salmon and trout (Oncorhynchus spp.) (n = 371 studies). In addition to the aggregate, we compared groups classified by subject matter. Next, to evaluate whether riverscape ecology has embraced space at the expense of time, we compiled research across taxa in which fish were enumerated in a spatially continuous fashion (n = 46). We found that ecological Oncorhynchus spp. research was biased towards summer (40% occurred during June-August) and the month of June in particular, at the expense of winter work (only 13% occurred during December-February). Riverscape studies were also biased toward summer (47% of studies) and against winter (11%). It was less common for studies to encompass multiple seasons (43% of ecological Oncorhynchus spp. studies and 54% of riverscape studies) and most were shorter than 4 months (73% of ecological Oncorhynchus spp. studies and 81% of riverscape studies). These temporal biases may cause researchers to overemphasize ecological phenomena observed during summer and limit our ability to recognize seasonal interactions such as carry-over effects or compensatory responses. Full year and winter studies likely hold valuable insights for conservation and management.

Many herpetofauna species in the Pacific region have undergone dramatic declines due to invasive species, primarily introduced predators. Fiji has two species of endemic frogs (Family Ranidae, Genus Platymantis) one of which, the Fiji Ground Frog, P. vitianus, has been extirpated from much of its original range due to the mongoose Herpestes javanicus. We conducted a short-term follow up survey to confirm an earlier report (September 2003) of the co-existence between mongoose and the ground frog on mainland Fiji (Vanua Levu). We used systematic nocturnal and diurnal surveys to census the frog fauna of Waisali Reserve and described microhabitat and threatening processes. A series of key management actions are outlined to facilitate the long-term conservation of this frog in the reserve.
