Predicting potential distributions of large carnivores in Kenya: An occupancy study to guide conservation

Femke Broekhuis, Shadrack Ngene, Arjun Gopalaswamy, Anastacia Mwaura, Stephanie Dloniak, Dedan Ngatia, Peter Tyrrell, Yumi Yamane & Nicholas Elliot
Aim: Species distribution maps are frequently the foundation upon which species-specific conservation strategies are developed, however, mapping species distribution is challenging, especially across large spatial extents. Our aim was to use a novel empirical approach to predict the national distribution for all six large carnivore species found in Kenya to guide conservation and management decisions by identifying knowledge and conservation gaps. Location: Kenya Methods: Data on carnivore presence and absence were collected through questionnaires and...

Predation strongly limits demography of a keystone migratory herbivore in a recovering transfrontier ecosystem

Fred Watson, Matthew Becker, Daan Smit, Egil Droge, Teddy Mukula, Sandra Martens, Shadrach Mwaba, David Christianson, Scott Creel, Angela Brennan, Jassiel M'soka, Angela Gaylard, Chuma Simukonda, Moses Nyirenda & Bridget Mayani
Large herbivore migrations are imperiled globally; however, the factors limiting a population across its migratory range are typically poorly understood. Zambia’s Greater Liuwa Ecosystem (GLE) contains one of the largest remaining blue wildebeest (Connochaetes taurinus taurinus) migrations, yet the population structure, vital rates, and limiting factors are virtually unknown. We conducted a long-term demographic study of GLE wildebeest from 2012–2019 of 107 collared adult females and their calves, 7,352 herd observations, 12 aerial population surveys,...

Spatiotemporal predictions of the alternative prey hypothesis: Predator habitat use during decreasing prey abundance

Mitchell Brunet, Kevin Monteith, Katey Huggler, Daniel Thompson, Patrick Burke, Mark Zornes, Patrick Lionberger, Miguel Valdez & Joseph Holbrook
The alternative prey hypothesis supposes that predators supported by a primary prey species will shift to consume alternative prey during a decrease in primary prey abundance. The hypothesis implies that during declines of one prey species, a predator modifies their behavior to exploit a secondary, or alternative, species. Despite occurring in many systems, the behavioral mechanisms (e.g., habitat selection) allowing predators to shift toward alternative prey during declines in the abundance of their primary prey...

Behavioral responses of a large, heat-sensitive mammal to climatic variation at multiple spatial scales

Tana L. Verzuh, Savannah Rogers, Paul Mathewson, Alex May, Warren Porter, Corey Class, Lee Knox, Teal Cufaude, L. Embere Hall, Ryan Long & Kevin Monteith
1. Climate warming creates energetic challenges for endothermic species by increasing metabolic and hydric costs of thermoregulation. Although endotherms can invoke an array of behavioral and physiological strategies for maintaining homeostasis, the relative effectiveness of those strategies in a climate that is becoming both warmer and drier is not well understood. 2. In accordance with the heat dissipation limit theory, which suggests that allocation of energy to growth and reproduction by endotherms is constrained by...

Climatic drivers and ecological impacts of a rapid range expansion by non-native smallmouth bass

Mark Kirk
Smallmouth bass (Micropterus dolomieu) are a globally introduced fish species that have experienced widespread range expansions in recent decades and which can have deleterious effects on native fish communities. Rapidly assessing their expansions will aid conservation and management actions geared towards controlling their spread and mitigating their impacts. Smallmouth bass have recently experienced a rapid upstream expansion in a Great Plains river (Laramie River, Wyoming, USA), which provided an opportunity to evaluate the drivers and...

Responses to natural gas development differ by season for two migratory ungulates

Mallory Sandoval Lambert, Hall Sawyer & Jerod Merkle
While migrating, animals make directionally persistent movements and may only respond to human-induced rapid environmental change (HIREC), such as climate and land-use change, once a threshold of HIREC is surpassed. In contrast, animals on other seasonal ranges (e.g., winter range) make more localized and tortuous movements while foraging and may have the flexibility to adjust the location of their range and the intensity of use within it to minimize interactions with HIREC. Because of these...

Phylogenomic analyses in Phrymaceae reveal extensive gene tree discordance in relationships among major clades

Diego F. Morales-Briones, Nan Lin, Eileen Huang, Dena Grossenbacher, James Sobel, Caroline Gilmore, David Tank & Ya Yang
• Premise of the study: Phylogenomic datasets using genomes and transcriptomes provide rich opportunities beyond resolving bifurcating phylogenetic relationships. Monkeyflower (Phrymaceae) is a model system for evolutionary ecology. However, it lacks a well-supported phylogeny for a stable taxonomy and for macroevolutionary comparisons. • Methods: We sampled 24 genomes and transcriptomes in Phrymaceae and closely related families, including eight newly sequenced transcriptomes. We reconstructed the phylogeny using IQ-TREE and ASTRAL, evaluated gene tree discordance using PhyParts,...

Immune assay data for Lycaeides melissa larvae reared on different host plants and with/without egg microbes

Su'ad Yoon, Joshua Harrison, Angela Smilanich & Matthew Forister
1. Maternally transmitted microbes are ubiquitous. In insects, maternal microbes can play a role in mediating the insect immune response. Less is known about how ecological factors, such as resource use, interact with maternal microbes to affect immunity. 2. In the context of a recent colonization of a novel host plant by the Melissa blue butterfly (Lycaeides melissa), we investigated the interaction between host plant use and vertically transmitted, extracellular egg-associated microbes in determining the...

Invasive predator diet plasticity has implications for native fish conservation & invasive species suppression

Hayley Glassic, Christopher Guy, Dominique Lujan, Lusha Tronstad, Michelle Briggs, Lindsey Albertson & Todd Koel
Diet plasticity is a common behavior exhibited by piscivores to sustain predator biomass when preferred prey biomass is reduced. Invasive piscivore diet plasticity could complicate suppression success; thus, understanding invasive predator consumption is insightful to meeting conservation targets. Here, we determine if diet plasticity exists in an invasive apex piscivore and how plasticity could influence native species recovery benchmarks and invasive species suppression goals. We compared diet and stable isotope signatures of invasive lake trout...
