Influence of landfill use on nest‐site selection and breeding success in white storks

Journal of Zoology, Volume 321, Issue 3, Page 175-187, November 2023., 2023
Breeding near landfills may determine habitat preference and selection in white storks, however breeding success depends on habitat quality in the surrounding area more than the distance to the landfill. Abstract Landscape transformation by humans through habitat degradation, agriculture intensification and urbanization results in the loss of natural ...

Combining otolith chemistry and genetics to infer the population structure of yellow snapper Lutjanus argentiventris

Ecosphere, Volume 14, Issue 10, October 2023., 2023
Abstract Developing a metapopulation framework contributes to the understanding of spatial processes and structures in populations, providing basic information for conservation biology. However, the extent to which the metapopulation structure differs geographically and across life history stages is unexplored for most fishes.

Rpadrino: An R package to access and use PADRINO, an open access database of Integral Projection Models

Methods in Ecology and Evolution, Volume 13, Issue 9, Page 1923-1929, September 2022., 2022
Abstract Discrete time structured population projection models are an important tool for studying population dynamics. Within this field, integral projection models (IPMs) have become a popular method for studying populations structured by continuously distributed traits (e.g. height, weight).

Using historical spy satellite photographs and recent remote sensing data to identify high‐conservation‐value forests

Conservation Biology, Volume 36, Issue 2, April 2022., 2022
Abstract High‐conservation‐value forests (HCVFs) are critically important for biodiversity and ecosystem service provisioning, but they face many threats. Where systematic HCVF inventories are missing, such as in parts of Eastern Europe, these forests remain largely unacknowledged and therefore often unprotected.

Automated detection of frog calls and choruses by pulse repetition rate

Conservation Biology, Volume 35, Issue 5, Page 1659-1668, October 2021., 2021
Abstract Anurans (frogs and toads) are among the most globally threatened taxonomic groups. Successful conservation of anurans will rely on improved data on the status and changes in local populations, particularly for rare and threatened species.

Scaling up private land conservation to meet recovery goals for grassland birds

Conservation Biology, Volume 35, Issue 5, Page 1564-1574, October 2021., 2021
Abstract Long‐term population declines have elevated recovery of grassland avifauna to among the highest conservation priorities in North America. Because most of the Great Plains is privately owned, recovery of grassland bird populations depends on voluntary conservation with strong partnerships between private landowners and resource professionals ...

Fine-scale population structure and asymmetrical dispersal in an obligate salt-marsh passerine, the Saltmarsh Sparrow (Ammodramus Caudacutus) [PDF]

, 2012
Understanding the spatial scale of gene flow can yield valuable insight into the ecology of an organism and guide conservation strategies. Fine-scale genetic structure is uncommon in migratory passerines because of their high vagility and presumed high ...
