摘要

Interactions between temperature and moisture on seed germination are not clearly understood. We hypothesized that high temperatures and low moisture would inhibit seed germination. We analyzed germination under four temperatures (18-36 degrees C) and under five water limiting conditions, using Polyethylene glycol (PEG) 6000 (0.0-1.0 MPa) for eight dominant species from Cactaceae (Isolatocereus dumortieri, Echinocactus platyacanthus, and Ferocactus histrix), Asparagaceae (Yucca decipiens, Agave salmiana, and Agave lechuguilla) and Fabaceae (Acacia schaffneri and Prosopis laevigata) from the Chihuahuan Desert. We used the September (when seed germination is more likely to occur) mean (18 degrees C), the historic highest mean temperature for this month (25 degrees C), the maximum temperature registered for the month (32 degrees C), and 36 degrees C, considering a 4 degrees C increase. Species had fewer seeds germinating with decreasing moisture and high temperature. Prosopis laevigata however, showed high germination across temperatures and on almost all water potentials. Isolatocereus dumortieri and E. platyacanthus had few seeds germinating at 18 degrees C but with a negative effect of low water potential for 18 degrees C and 36 degrees C. This is the first study including the combined effect of water potential and temperatures on germination of a set of Chihuahuan Desert species. (C) 2017 Elsevier Ltd. All rights reserved.

Experimental climate change in desert steppe reveals the importance of C-4 plants for ecosystem carbon exchange

Guangyi Lv, Mengting He, Qi Li, Zhanyi Wang, Chengjie Wang

Summary: Climate change has significantly affected plant community composition and ecosystem carbon exchange in grasslands. However, the effects of long-term temperature increase and precipitation on degraded desert steppe remain unclear. Our study showed that warming and increased precipitation improved the cover and height of C-4 plants, while decreasing the cover and density of C-3 plants in the plant community. Additionally, it was found that climate warming and increased precipitation significantly increased net ecosystem CO2 exchange.

High Temperature and Elevated CO2 Modify Phenology and Growth in Pepper Plants

Jade M. Pereyda-Gonzalez, Clelia De-la-Pena, Wilmer Tezara, Roberto Zamora-Bustillos, Ruben H. Andueza-Noh, Jehu G. Noh-Ku, Maria Carrera-Marin, Rene Garruna

Summary: This study aimed to investigate the effects of temperature and CO2 on seed emergence, seedling quality, and phenological stage of Capsicum chinense and Capsicum annum. The results showed that temperature and CO2 had no effect on seed emergence, but influenced seedling mortality and growth parameters. High temperature affected seedling survival and leaf area, while elevated CO2 had positive effects on leaf area and flower and fruit production. However, high temperature delayed flower phenology, increased flower abortion, and inhibited fruit set. Elevated CO2 counteracted the negative effects of high temperature on growth parameters and flower number, but was not sufficient to prevent flower abortion and detrimental morphological characteristics of fruit caused by a temperature of 40 degrees C.

Cryptic declines of small, cold-water specialists highlight potential vulnerabilities of headwater streams as climate refugia

Blake R. Hossack, Michael T. LeMoine, Emily B. Oja, Lisa A. Eby

Summary: Increasing temperatures and climate-driven disturbances are threatening cold-water specialists, such as slimy sculpin. However, small or non-game species, like tailed frogs, are often neglected in monitoring and planning programs. A recent study in Montana revealed larger declines in occupancy for slimy sculpin compared to socially valued salmonid fishes. Similarly, tailed frog occupancy decreased by 19% and was linked to reductions in canopy cover and increased stream temperature.

Thermal adaptation of pelage in desert rodents balances cooling and insulation

Eric A. Riddell, James L. Patton, Steven R. Beissinger

Summary: Phenotypic convergence can be driven by similar selective pressures or intrinsic constraints. The evolution of thermal properties of mammalian pelage in the Mojave Desert was studied, revealing that species preferring arid habitats exhibit lower conductivity and thinner pelage, which provides comparable insulation due to lower conductivity. This suggests that pelage readily evolves to environmental pressures. Thermoregulatory simulations showed that arid specialists reduce energetic costs by evolving lower conductivity, supporting adaptive evolution of pelage.

Illera, Pedro Jordano, Przemyslaw Kurek, Benno Simmons, Emilio Virgos, William J. Sutherland, Anna Traveset

Summary: Climate change is rapidly affecting the redistribution of life on Earth, with migratory birds playing a crucial role in helping plants track climate change through seed dispersal. However, the direction of seed dispersal by birds can vary depending on the fruiting period of plant species and the direction of their migration. The study found that most plant species in European woodland communities are dispersed by birds migrating southward, with only a few species being dispersed by birds migrating northward, indicating a potential impact on the formation of novel plant communities and their ecosystem functions.

Evaluation of IMERG precipitation product over various temporal scales in a semi-arid region of southern Iran

Rahim Najafi Tireh Shabankareh, Pardis Ziaee, Mohammad Javad Abedini

Summary: This study evaluated the IMERG satellite-based precipitation product in the Fars province of Iran using daily rain gauges as reference data. The results showed that the product tends to overestimate light rainfall and underestimate heavy rainfall, with the best performance in the 40-80 mm/day range. The accuracy of the product varies by month and is less biased in months with milder temperatures. Additionally, there was a higher correlation in mid-elevated areas, positive bias in low-elevated areas, and negative bias in high-elevated areas. Longer time scales showed considerable improvement in the IMERG estimates.
