Context‐Dependent Effects of Beavers (Castor spp.) on Freshwater Pearl Mussels (Margaritifera margaritifera) in European Rivers 河狸对欧洲河流中的淡水珍珠贝 (Margaritifera margaritifera) 存在情境依赖性影响

open access: yesWildlife Letters, EarlyView.
The study explores how beavers (Castor spp.) affect endangered freshwater pearl mussels (Margaritifera margaritifera) in European rivers. Beaver dams can harm small, fragmented mussel populations by reducing flow, increasing sediment, and potentially limiting host fish movement, while larger populations may benefit from improved bed stability and ...

Assessing the Influence of Interference Competition on Ecologically Similar Species Threatened by Habitat Loss 评估干扰性竞争对受栖息地丧失威胁的生态相似物种的影响

open access: yesWildlife Letters, EarlyView.
We staged dyadic interaction trials between two kangaroo rat species threatened by habitat loss to test whether one species dominates in direct interactions in the field. We found that Stephens’ kangaroo rat (Dipodomys stephensi) residents and intruders were dominant over Dulzura kangaroo rat (Dipodomys simulans). These results suggest that D. simulans

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

open access: yesJournal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...

Niche occupancy of Jamaican bat caves: Diversity increases isotopic niche packing

open access: yesJournal of Animal Ecology, EarlyView.
Tropical bat caves are home to hundreds of thousands of bats of multiple species. In Jamaica, we found that isotopic niche packing is the likely mechanism of coexistence at more diverse sites. Abstract There are over 1000 documented caves across Jamaica, many of them used by diverse communities of bats.

Forces Behind South Australia's Unusual Structural Changes Since 1840

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The agricultural sector's share of GDP in growing economies typically declines but, for a century from the early 1850s, Australia's did not. That trend is most evident for the former colony and now State of South Australia (SA). Moreover, that share for SA has been almost flat since 1980 as well, along with the agricultural sector's share of ...
