Since European settlement, the Western calendar has insufficiently accounted for the seasonal nuances and multiple temporalities of Australia. Beginning with Tim Entwistle’s recent proposal to revise the four-season Australian norm, this article traces the emergence of the Western calendar in Europe and its institutionalization ‘Down Under.’ With its emphasis on land-based calendars, the Indigenous Weather Knowledge Project is a partnership between Aboriginal communities and the Bureau of Meteorology aimed at preserving and promoting knowledge of the endemic seasons of Australian regions. (...) As themost recent addition to the IWKP, the six-season Nyoongar calendar of the South-West of Western Australia is based on meteorological conditions, such as wind directions and temperatures, but also on the procurement of food, maintenance of cultural knowledge, and performance of ceremonies. Through the fusion of phenomenological and phenological approaches, the endemic seasons of Australia can be appreciated in their depth and extent. (shrink)

Phenologists track the seasonal behavior of plants and animals in response to climatic change. During the second half of the twentieth century, phenologists developed a large-scale project to monitor the flowering time of the common lilac across the United States. By the 1960s, this approach offered a potential plant-based indicator of anthropogenic climate change, a biological signal amidst the emerging narrative of increasing levels of atmospheric carbon dioxide. As a tangible representation of changes in climate—warmer temperatures lead to earlier blooming—phenology (...) proved highly legible to scientists, politicians, and laypeople. Yet, as phenology gained broader repute in the 1960s, both in agricultural stations and as a component program of the International Biological Program, it struggled to align itself epistemically with the regnant disciplinary assumptions of mid-century ecology. Operating in the hinterlands between laboratory and field, biology and meteorology, ecological theory and agronomy practice, phenologists challenged prevailing notions of the model organism and what it meant to study biology in the field. Rebranding the discipline as a component of ecosystem modeling, scientists successfully brought phenology within the purview of mainstream ecology. In so doing, however, they obscured its climate-relevant meteorological character and stymied the development of a biological narrative of climate change. (shrink)

Biologists increasingly report anthropogenic disruptions of both organisms and ecosystems, suggesting that these processes are a fundamental, qualitative component of the Anthropocene. Nonetheless, the notion of disruption has not yet been theorized in biology. To progress in that regard, we work on a special case. Relatively minor temperature changes impact plant-pollinator synchrony, disrupting mutualistic interaction networks. Understanding this phenomenon requires a specific rationale since models describing them use both historical and systemic reasoning. Specifically, history justifies that the system is initially (...) in a very narrow part of the possibility space where it is viable, and the disruption randomizes this configuration. Building on this rationale, we develop a formal framework inspired by Boltzmann's entropy. With empirical networks, we show historical trends depending on latitude. Then we propose an initial definition of disruption in ecology. When a specific historical outcome contributes to a system's viability, disruption randomizes this outcome, decreasing viability.

Ecologists traditionally regard time as part of the background against which ecological interactions play out. In this book, Eric Post argues that time should be treated as a resource used by organisms for growth, maintenance, and offspring production. Post uses insights from phenology -- the study of the timing of life-cycle events -- to present a theoretical framework of time in ecology that casts long-standing observations in the field in an entirely new light. Combining conceptual models with field data, he (...) demonstrates how phenological advances, delays, and stasis, documented in an array of taxa, can all be viewed as adaptive components of an organism's strategic use of time. Post shows how the allocation of time by individual organisms to critical life history stages is not only a response to environmental cues but also an important driver of interactions at the population, species, and community levels. To demonstrate the applications of this exciting new conceptual framework, Time in Ecology uses meta-analyses of previous studies as well as Post's original data on the phenological dynamics of plants, caribou, and muskoxen in Greenland.--Back cover.

Acoustic codes assure the intra and interspecific communication of vocal animals. They are composed by a sequence of nominal entities and by magnitude modulation confirming in such a way contemporarily a behavioural and ecological nature. The acoustic codes find evidence in the acoustic niche hypothesis by which species in order to reduce interspecific competition occupy a restricted portion of the available frequencies modulating very precise acoustic cues . Their evolution, like other aspect of biology, is under control of the environmental (...) conditions assuming the more favourable configurations. These nominal entities respond also to the amount of energy by which are emitted allowing to the eavesdropping individuals to range the distance at which a potential competitor is broadcasting a signal. Environmental alterations, especially if of anthropogenic origin, can produce severe consequence of the acoustic codes that in turn may affect the prey–predator balance and the complexity of communities. In fact acoustic codes under an environmental constraint like human noise intrusion can be modified in order to reduce a masking effect, demonstrating their phenological plasticity. The new ecological discipline of soundscape ecology offers the possibility to investigate the nature and the evolution of the acoustic codes in different environmental conditions. (shrink)

Mongolian traditional botanical knowledge has been rarely researched concerning the ethnobotany theory and methodology in the last six decades ). However, most of the known literature of indigenous knowledge and information regarding the use of local wild plants among Mongolian herders was first documented by several botanical research of Russian researchers in Mongolia through the 1940s and 1950s. One of the most comprehensive works was completed by A. A. Yunatov, which is known as “Fodder Plants of Pastures and Hayfields of (...) the People’s Republic of Mongolia”. Yunatov’s research sampled forage plants in Mongolia from 1940 to 1951 and subsequently published a study in 1954. The original transcript of FPM was later translated into Chinese and Mongolian during 1958 and 1968. In addition to morphological characteristics, distribution, habitat, phenology, palatability, and nutrition of forage plants, Yunatov`s record collected local names, the folk understanding and evaluation of the forage, as well as other relevant cultural meanings and the use of local wild plants in FPM through interviews. The book contains the most precious records created in the 1940s and 1950s on folk knowledge of the Mongolians' wild plants in Mongolia. It was composed of 8 chapters and 351 pages in total. The fifth chapter of FPM, entitled “The systematic overview of forage plants,” making up 272 pages. The order and content of the book-oriented along with profiles of specific plants. Yunatov collected detailed information on plants, such as the local name, morphology, distribution, habitats, ecological characteristics, and phenology. He also discussed the palatability of livestock, particular forage use, other usages, and chemical composition. Through careful reading and understanding of all three versions of the book ), the FPM-listed information of edible plants was categorized using ethnobotanical dependent analysis. The list of edible plants was ranked based on purposes and ethnobotanical inventories as per methodology and analysis used in the ethnobotany research. FPM listed 35 species are part of 15 families and 25 genera of wild edible plants. Most species belong to Liliaceae and Allium. Naturally grown grain and some food substitutes come from the starchy organs, such as seeds, bulbs, roots, and rhizomes of 12, accounting for 34.28% of all species. Wild vegetables come from the parts of a young plant, tender leaves, young fruits, lower leg of stems, and bulbs of 9 species, accounting for 25.71% of all species. There are only three species of wild fruits, accounting for 8.57% of all edible plant species. Tea substitutes consist of leaves, roots, follicle, and aboveground parts of 8 wild plant species, accounting for 22.85% of all species. Seasonings from the wild were made of the elements such as seeds, rhizomes, tender leaves of 7 species, accounting for 20.00% of all species. Similarities and differences are noticeable in utilizing wild edible plants among Mongolian populations living in Mongolia and Inner Mongolia. Six species of wild edible plants listed in FPM have been proven to be collected and consumed by Mongolians from the Genghis Khan era in the twelfth century to the present day. This proved that the Mongolians have a tradition of recognizing and utilizing wild plants, demonstrating historical and theoretical value. Seven species of plants mentioned in this book were closely correlated to the locals' processing of traditional dairy products, meat, and milk food. Yunatov was not an ethnobotanist, but his accurate documentation of interviews and surveys with Mongolians represents valuable information about the collection and consumption of local wild plants during 1940–1951 in Mongolia. His research mission meant to focus on forage grass, the feed plant that sustained livestock, while he also recorded plants consumed by humans. His records on the edible parts and intake methods of some plants are incomplete. Still, it provided ethnobotanical materials of a remarkable scientific value and a living history of ethnobotany in Mongolian regions. Even by today`s standards, it will be challenging to obtain first-hand information of the richness and to the extent of Yunatov’s research. (shrink)

Treatment of human differences in Scripture, particularly regarding the Cushites, raises the question of whether this group was “racially othered” by the Hebrews, or whether differences in phenological presentation and cultural customs were vested with less significance than they have been in a contemporary milieu.
