From rhetoric to measurement: The economics of wetland conservation

Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract Wetland conservation continues to be a pressing issue as wetlands continue to be lost due to urban, industrial, and agricultural expansion. This paper synthesizes the current knowledge about wetland conservation economics in Canada, with a focus on prairie landscapes. We review the methods economists use to empirically measure the costs (i.e.,

Evolutionary and environmental determinants of heat tolerance and acclimation capacity in herpetofauna

Conservation Biology, EarlyView.
Abstract Exploring heat tolerance and acclimation capacity can provide an effective approach to evaluating species’ sensitivity to extremely high temperatures due to climate warming. Despite some work on amphibian and reptile thermophysiological adaptation, related questions remain. We reviewed the literature to provide a synthesis of worldwide data on

Direct interactions between livestock guarding dogs and wildlife in a transhumance grazing system

Conservation Science and Practice, EarlyView.
This study explores the interactions between livestock guarding dogs (LGDs) and wildlife in Romania's southern Carpathian Mountains, revealing that while LGDs sometimes chase or kill wildlife, such instances are infrequent. Most wildlife remains found in LGD scats were insects, with only 9% of scats containing vertebrate wildlife remains.

Riding the monsoon: Geography and Iron Age trade in the Indian Ocean

The Economic History Review, EarlyView.
Abstract This paper exploits ancient textual sources to develop a database of ancient trade in the Indian Ocean and model trade in the region during the Iron Age. Wind‐speed data are used to construct a gravity model of trade and are combined with detailed textual data from the Periplus of the Erythraean Sea to analyse historical development trends in ...
