Abstract Investigating fundamental processes in biology requires the ability to ground broad questions species‐specific natural history. This is particularly true study of behavior because an organism's experience environment will influence expression and opportunity for selection. Here, we provide a review history burying beetles genus Nicrophorus groundwork comparative work that showcases their remarkable behavioral ecological diversity. Burying have long fascinated scientists well‐developed parenting behavior, exhibiting extended post‐hatching care offspring varies extensively within across taxa. Despite burgeoning success as model system evolution, there has not been ecology, evolution over 25 years.

Wildlife trade is a key driver of extinction risk, affecting at least 24% terrestrial vertebrates. The persistent removal species can have profound impacts on risk and selection within populations. We draw together the first review characteristics known to drive use - identifying with larger body sizes, greater abundance, increased rarity or certain morphological traits valued by consumers as being particularly prevalent in trade. then ecological implications this trade-driven selection, revealing direct effects natural populations for traded species, which includes against desirable traits. Additionally, there exists positive feedback loop between depleted tend easy human access points, result harvested has potential alter source-sink dynamics. Wider cascading ecosystem repercussions from trade-induced declines include altered seed dispersal networks, trophic cascades, long-term compositional changes plant communities, forest carbon stocks, introduction harmful invasive species.

Body condition is a measure of the health and fitness an organism represented by available energy stores, typically fat. Direct measurements fat are difficult to obtain non-invasively, thus body usually estimated calculating indices (BCIs) using mass length. The utility BCIs contingent on relationship fat, thereby validation studies should be performed select best performing BCI before application in ecological investigations. We evaluated 11 883 Argentine black white tegus ( Salvator merianae ) removed from their non-native range South Florida, United States.

ABSTRACT Juvenile growth rate is a critical demographic parameter, as it shortens the time to maturity and often dictates how long individuals remain vulnerable predation. However, developing mechanistic understanding of factors determining rates can be difficult for wild populations. The gopher tortoise ( Gopherus polyphemus ) an ecosystem engineer threatened by habitat loss deficient management pinelands in southeastern United States. We investigated governing immature explored use drone‐based imagery assessment comparing predictive models based on ground‐based plant surveys versus drone‐derived data. From 2021 2022, we tracked measured tortoises native sandhill human‐modified, ruderal south‐central Florida. Using quarterly, high‐resolution drone imagery, quantified cover types vegetation indices at each occupied burrow frequency occurrence forage species hand. Annual were higher than those highest published this species. Models data able explain similar proportions variation ground‐collected measures forage, especially during late dry season when both most predictive. Habitat differences nitrogen content also more pronounced season, dominant ground (bahiagrass) had much (wiregrass). Despite concerns about potential growth‐survival trade‐offs, did not exhibit lower apparent survival. Our findings indicate that dominated nutritious non‐native grass provide valuable supplement through mechanism increased due quality. Finally, our study demonstrates technology may facilitate providing less labor‐intensive ways assess quality other imperiled herbivores.

The introduction of nonnative species is a leading cause biodiversity loss. Many invasive are cryptic or elusive in nature and therefore often evade detection, complicating their management. Occupancy modeling can reveal the presence spread over time has important management implications. Camera traps be used to estimate occupancy, proportion sites that occupied by target species.

Excluding non-target species from invasive control efforts can be challenging due to attraction trap structure, baits, and lures. Various methods have been used deter entering or disturbing traps including altered features (e.g., mesh size, trip mechanism, entrances), staking traps, chemical deterrents. Invasive populations of Argentine Black White Tegu lizards ( Salvator merianae ) occur in several locations across Florida Georgia, there are ongoing trapping them. At sites mammals disturb most the lizard (>80%), consume egg bait/lures, thus reduce efficacy. In contrast, our site has fewer problems with mammals. Our goal was quantify efficacy capsaicin-coated eggs, a known distasteful irritant mammals, as bait deterrent live set for tegus both Georgia Florida. We conducted feeding assays on three found that individuals readily consumed food coated capsaicin. then three-part, experiment test 1) if disturbance by habituated eggs without capsaicin decreased when were deployed 2) not (treated untreated) disturbed at same rate those 3) tegu capture rates different treated we did decrease applied an area previously this nor novel area. Florida, no significant difference captures using capsaicin-treated vs. untreated bait. Tegus tolerant capsaicin, but mammal traps.
