Establishment patterns of saguaro cactus (Carnegiea gigantea) at the microsite scale help explain saguaro regeneration and distributions in heterogenous, regional habitats. [PDF]
Am J BotAbstract Premise Establishment of long‐lived perennial plants is a pivotal event that often leads to reproductive maturity. The population dynamics of the giant saguaro cactus (Carnegiea gigantea) have been investigated over large spatial areas, but establishment patterns have not been studied at the microsite (1 m) scale.

Invasive Buffelgrass, Cenchrus ciliaris, Balances Opportunistic Acquisition of Foliar fungi With Host and Environmental Filtering in Its Introduced Range. [PDF]
Mol EcolABSTRACT Plants host diverse assemblages of fungi on their foliar tissues, both in internal compartments and on exterior surfaces. When plant distributions shift, they can move with their fungal associates (i.e., co‐introduction) or acquire new associates present in the novel environment (host‐jumping).

Uprooted buffelgrass thatch reduces buffelgrass seedling establishment [PDF]
Arid Land Research and Management, 2016 ABSTRACTBuffelgrass (Pennisetum ciliare (L.) Link), a non-native perennial bunchgrass, invades ecologically intact areas of the Sonoran Desert. It competitively excludes native plants and increases fire frequency and intensity. Since the 1990s, whole buffelgrass plants have been manually uprooted and removed to control the invasion in southern Arizona.

The USA National Phenology Network's Buffelgrass Green‐up Forecast map products
Ecological Solutions and Evidence, 2021 Buffelgrass (Cenchrus ciliaris syn. Pennisetum ciliare) was introduced to Sonoran Desert in the early 20th century and has become widespread at low elevations. This perennial bunchgrass accumulates abundant biomass that can carry fires through ecosystems

Hydroclimatic Rebound Drives Extreme Fire in California's Non-Forested Ecosystems. [PDF]
Glob Chang BiolHydroclimatic rebound occurs when unusually wet periods are followed by intense drying, or vice versa, creating sharp moisture swings. We show that this process drives extreme fire activity in California's non‐forested regions, such as deserts and Mediterranean ecosystems, and was particularly evident in the 2025 Los Angeles wildfires.

Land tenure contributions to protected area growth under alternative conservation targets in the Australian monsoon tropics. [PDF]
Conserv BiolAbstract As the global protected area (PA) network expands to meet international targets, it is important to assess whether traditional reliance on public land will suffice for projected PA growth or whether other tenures, such as Indigenous or pastoral lands, may increasingly contribute.

Feasibility and application of using Texas horned lizard scat to predict lizard size and age class
Wildlife Society Bulletin, Volume 47, Issue 3, September 2023., 2023 Scat from Texas horned lizards (THL, Phrynosoma cornutum) can be used as an indirect method to assess population age class structure, body size, and population estimates. Our growth rate analyses suggest that THL experience slower growth rates today than during previous decades.

Can competition with pasture be used to manipulate bellyache bush (Jatropha gossypiifolia L.) population biology? [PDF]
, 2013 Bellyache bush (Jatropha gossypiifolia L.) is an invasive weed that poses economic and environmental problems in northern Australia. Competition between pasture and bellyache bush was examined in North Queensland using combinations of five pasture ...

Advances in Agriculture, Volume 2023, Issue 1, 2023., 2023 Sustainable farm animal raising is dependent on the production of sufficient quantities and quality of forages and fodder, especially in dry regions. Improved forage and feed species are an option for these aspects because adequate feed resources enhance soil health and carbon, generate income, and reduce emissions.

The Role of Citizen Science in Earth Observation [PDF]
, 2017 Citizen Science (CS) and crowdsourcing are two potentially valuable sources of data for Earth Observation (EO), which have yet to be fully exploited. Research in this area has increased rapidly during the last two decades, and there are now many examples
