Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

open access: yesAnimal Conservation, EarlyView.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Association of calving factors and labor duration with postpartum uterine health in Holstein cattle

open access: yesJournal of Dairy Science
: The objective of this observational study was to investigate the association between the duration of labor, calving assistance, and uterine diseases, as well as estimate a reference time to be used as a guideline for providing calving assistance based ...

Potential vs. Realized Large Carnivore Density: The Influence of Livestock on Carnivore Carrying Capacity Estimation

open access: yesAnimal Conservation, EarlyView.
In an unfenced mixed‐use savanna landscape in Namibia, we compared realized densities of leopards and cheetahs estimated using spatial capture–recapture models with prey‐based carrying capacity predictions. Leopard densities exceeded predictions based on wild prey alone but closely matched livestock‐supplemented models, suggesting that vulnerable ...

Modeling ice cliff stability using a new Mohr–Coulomb-based phase field fracture model

open access: yesJournal of Glaciology
Iceberg calving at glacier termini results in mass loss from ice sheets, but the associated fracture mechanics is often poorly represented using simplistic (empirical or elementary mechanics-based) failure criteria.

Flow‐pattern evolution of the Scandinavian Ice Sheet indicated by the subglacial lineation record over Norway, Sweden and Finland

open access: yesBoreas, EarlyView.
We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

Weichselian history of the Fennoscandian Ice Sheet centre, Kvarken archipelago, western Finland—flow shifts, thermal regime and deglaciation

open access: yesBoreas, EarlyView.
Rapid thaw of the Earth's cryosphere in response to anthropogenic warming highlights the need to identify and understand the contrasting signatures of past ice‐sheet stability and collapse. The Kvarken archipelago, western Finland, at the centre of the former Fennoscandian Ice Sheet (FIS), has been designated a UNESCO World Heritage site in recognition

Taxonomic and functional diversity of benthic foraminifera as a promising proxy for tidewater glacier retreat

open access: yesBoreas, EarlyView.
Ice sheets and glaciers globally are losing mass at increasing rates, with the strongest changes occurring at tidewater glaciers. These are rapidly retreating and often transitioning to land‐terminating with implications for sea level change and ecosystem functioning.

Environmentally adjusted productivity growth and shadow prices for dairy farms

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.

Interplay of crop diversity and agricultural area in agroecosystem services: Analytical and empirical study on local water quality

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract This study expands the framework for analyzing the interplay of agricultural area and crop diversity on agroecosystem services by incorporating the species‐area relationship concept from biology. We estimate panel fixed effects models that include both agricultural area and crop diversity, along with their interaction term.

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities

open access: yesConservation Biology, EarlyView.
Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.
