Chemical Properties, Ruminal Fermentation, Gas Production and Digestibility of Silages Composed of Spineless Cactus and Tropical Forage Plants for Sheep Feeding [PDF]

Animals
The aim was to evaluate the chemical composition, carbohydrates, protein fractionation and in vitro gas production of silages composed of spineless cactus and tropical forages and their effect on sheep performance.

Establishment patterns of saguaro cactus (Carnegiea gigantea) at the microsite scale help explain saguaro regeneration and distributions in heterogenous, regional habitats. [PDF]

Am J Bot
Abstract 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 Ecol
ABSTRACT 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).

Leishmaniasis Transmission Risk at the Forest-Peridomestic Interface in an Area of Southern Sinaloa, Mexico: Entomological, Molecular, and Climatic Evidence. [PDF]

J Parasitol Res
Leishmaniasis, caused by Leishmania spp. and transmitted by phlebotomine sand flies, affects almost 1,000,000 people annually across more than 90 countries. In Mexico, growing evidence of locally acquired transmission in northwestern states makes ecoepidemiological work increasingly urgent.

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

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.

Spittlebug and Buffelgrass Responses to Summer Fires in Mexico [PDF]

Journal of Range Management, 1999
Summer burning was used to reduce spittlebug (Aeneolamia albofasciata Lall.) populations in buffelgrass [Cenchrus ciliaris (L.) Link] on the Carbo Livestock Research Station in Sonora, Mexico. Five treatments included (1) an untreated control; (2) burning 7-14 days before the summer rains when the insect and the plant were inactive; (3) burning after ...

Hydroclimatic Rebound Drives Extreme Fire in California's Non-Forested Ecosystems. [PDF]

Glob Chang Biol
Hydroclimatic 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 Biol
Abstract 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.

Biocrusts do not differentially influence emergence and early establishment of native and non‐native grasses

Ecosphere, 2021
Biological soil crusts (biocrusts) cover the soil surface of global drylands and interact with vascular plants. Biocrusts may influence the availability and nature of safe sites for plant recruitment and the susceptibility of an area to invasion by non ...
