Free-roaming horses exceeding appropriate management levels affect multiple vital rates in greater sage-grouse Free-roaming horses exceeding appropriate management levels affect multiple vital rates in greater sage-grouse
Since the passage of the Wild Free-Roaming Horses and Burros Act of 1971, federal agencies have been responsible for managing free-roaming equids in the United States. Over the last 20 years, management has been hampered by direct opposition from advocacy groups, budget limitations, and a decline in the public’s willingness to adopt free-roaming horses (Equus caballus). As a result, free...

Bay Miwok evening primrose: A new subspecies of Oenothera deltoides (Onagraceae) endemic to California Bay Miwok evening primrose: A new subspecies of Oenothera deltoides (Onagraceae) endemic to California
California contains exceptional biodiversity in geography and plant life, including numerous endemic species, some of which are cryptic. The Oenothera deltoides Torr. & Frém. species complex represents a prime example of cryptic diversity. Here, we recognize a new subspecies of Oenothera deltoides, O. deltoides subsp. julpunensis S.F.Jones, subsp. nov., that is a local endemic of...

Orthoptera-specific target enrichment (OR-TE) probes resolve relationships over broad phylogenetic scales Orthoptera-specific target enrichment (OR-TE) probes resolve relationships over broad phylogenetic scales
Phylogenomic data are revolutionizing the field of insect phylogenetics. One of the most tenable and cost-effective methods of generating phylogenomic data is target enrichment, which has resulted in novel phylogenetic hypotheses and revealed new insights into insect evolution. Orthoptera is the most diverse insect order within polyneoptera and includes many evolutionarily and...

Hookworm prevalence in ocelots in Costa Rica is inconsistent with spillover from domestic dogs despite high overlap Hookworm prevalence in ocelots in Costa Rica is inconsistent with spillover from domestic dogs despite high overlap
Spatial overlap between wildlife and related domestic animals can lead to disease transmission, with substantial evidence for viral and bacterial spillover. Domestic and wild animals can also share potentially harmful helminth parasites, many of which have environmental transmission stages that do not require direct contact between hosts. We used camera traps, fecal sampling, and...

2023-2024 Coastal sage scrub and chaparral community monitoring for western San Diego County 2023-2024 Coastal sage scrub and chaparral community monitoring for western San Diego County
Western San Diego County is dominated by shrublands supporting biologically diverse native plant and animal communities. Widespread urbanization has led to regional habitat loss and fragmentation, and many species in these shrubland communities are rare, threatened, or endangered. Large-scale, multiple-species conservation planning has resulted in a regional preserve system that focuses...

Learning from a high-severity fire event—Conditions following the 2018 Carr Fire at Whiskeytown National Recreation Area Learning from a high-severity fire event—Conditions following the 2018 Carr Fire at Whiskeytown National Recreation Area
The 2018 Carr Fire burned more than 90 percent of Whiskeytown National Recreation Area, with much of the park burning at high severity. California yellow pine and mixed conifer forests are not well adapted to large, high-severity fires, and forest recovery after these events may be problematic. Large, high-severity fire patches pose difficulties for recruitment with interiors that are...

The relationship between maturation size and maximum tree size from tropical to boreal climates The relationship between maturation size and maximum tree size from tropical to boreal climates
The fundamental trade-off between current and future reproduction has long been considered to result in a tendency for species that can grow large to begin reproduction at a proportionately larger size. Due to the prolonged time required to reach maturity, estimates of tree maturation size remain unavailable and we lack a global view on the generality and the shape of this trade-off...
