Estimating European Pilchard (Sardina pilchardus) Total Length: New Equations for the Ichthyoarchaeological Record

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Throughout its area of distribution, in particular in the Iberian Peninsula, the European pilchard (Sardina pilchardus Walbaum 1792) has been an extensively exploited species since Prehistoric times. Our knowledge of the past fisheries of this clupeid nevertheless remains limited due to a scarcity of ichthyoarchaeological data, which reflects,

Archaeological and Biogeochemical Investigation of Past Human Relationships With Now‐Endangered Fish Species: Lake Sturgeon and American Eel in Southern Ontario, Canada

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This paper explores the historical ecology and biogeography of two fish species that are currently endangered in the North American Great Lakes region, that were of great importance to the Indigenous people in the region, and that are the focus of ongoing conservation efforts on the part of descendant communities: lake sturgeon (Acipenser ...

Statistical relationships between palagic fish catches and long-term series of environmental conditions in the southern Benguela region

, 1991
Three different techniques are used to established statistical relationships between annual pelagic fish species catches viz. pilchard, horse mackerel and chub mackerel, and monthly environmental indices. The three techniques are Spearman's Rank correlation, multiple regression and cross-correlations of the Box-Jenkins time series approach.

Environmental influence on intraspecific trait variation in the tropical seagrass Halodule uninervis

Oikos, EarlyView.
Intraspecific trait variation (ITV) enhances the precision of applying functional trait approaches in plant ecology. Despite its benefits, ITV is rarely considered in functional trait‐based seagrass research. The goal of our research is to measure ITV in the tropical seagrass species Halodule uninervis and assess the environmental factors associated ...

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

Oikos, EarlyView.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina

Matching habitat choice could be brightness‐based instead of hue‐based in green‐brown polymorphic grasshoppers

Oikos, EarlyView.
Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

Toward a Framework for Understanding Localization in Its Institutional Context: A Systems Perspective for Incorporating Local Values

Public Administration and Development, EarlyView.
ABSTRACT This paper explores how we might integrate local traditional values into a systems approach for analyzing and maximizing localization in the context of foreign aid. The paper situates localization and its operationalization in the older and broader literature on the political economy of foreign aid.

Urbanization and food transition in the Brazilian Amazon: From wild to domesticated meat

People and Nature, EarlyView.
Abstract Urbanization is expected to influence food transitions, resulting in a shift from wild foods to more domesticated foods. Concomitantly, food insecurity and urban demand for natural resources, including wildlife, are expected to increase overall, even when the per capita consumption is expected to decrease.
