Abstract:
... Dipodomys merriami is a rodent inhabiting grassland and desert scrub. Its distribution covers southwestern United States to southern Zacatecas. During 2015 a specimen was collected near the lagoon of Santiaguillo, Durango, Mexico. This species is reported for Durango; however, the new record extends the distribution about 58 km southwest from the nearest populations of Dipodomys merriami ambiguus, ...

However, there are still no operational indicators to measure forest status, especially for forest degradation. In the present study, we analysed the thermal response number (TRN, calculated by daily total net radiation divided by daily temperature range) of 163 sites including mature forest, disturbe ...

Abstract:
... It has been proposed in separate studies that fire or frost were the critical selective agents in the evolution of subshrub geoxyles (SGs) in African subtropical grasslands. We attempt to resolve this controversy by examining the evolution of SGs among the entire genus Protea that is widespread throughout southern/central Africa. We show that SGs are not confined to grasslands but occur in a wide ...

Abstract:

Reversing state transitions is difficult and costly. While some state transitions are relatively rapid, many take years to decades. Outside of theoretical models, very little is known about slower state transitions and how they unfold in time ...

Abstract:
... Most suids (Mammalia: Suidae, pigs) worldwide are omnivores living in closed environments, but the African warthog (Phacochoerus) has special adaptations for grazing in open environments. Similar specializations have been recorded from Plio-Pleistocene African suids. Four genera, Nyanzachoerus, Notochoerus, Kolpochoerus, and Metridiochoerus, have been discovered in late Miocene to middle Pleistoce ...

Despite this potential, there is limited documentation of the camel forage species, their availability and distribution. The study was conducted in Karamoja sub-region in Uganda and involved assessment of vegetation with intent to characterize the range of forage species a ...

It can play an important role in vegetation dynamics, especially in colonization processes through seed input on the vegetation and on the soil seed bank. We investigated the endozoochorous seed input of donkeys and goats on a semi-natural island ecosystem in the Mediterranean. Through germination experiments ...

Abstract:
... Regime shifts are difficult‐to‐reverse transitions that occur when an ecosystem reorganizes around a new set of self‐reinforcing feedbacks. Regime shifts are predicted to occur when the intensity of some exogenous driver variable, such as temperature, annual harvest rate, or nutrient addition rate, gradually approaches and crosses a threshold value, initiating a transition to an alternative state. ...

We evaluated the effects of land-use changes (1954–2012) on a threatened species, the ortolan bunting, in an agricultural area crucial for its conservation in Italy. We built a distribution model f ...

Abstract:
... Models of animal density often use coarse landcover categories that homogenize vegetation attributes, thereby limiting specificity of results. Alternatively, models including land surface phenology (LSP) metrics derived from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery capture continuous time-series data describing plant growth and senescence. LSP metrics may better disc ...

Abstract:
... This study compared litter decomposition dynamics of cork oak at three sites under different land-uses (grassland, shrubland and woodland), in a montado ecosystem in Southern Portugal. The montado is a protected habitat within the EU Habitats Directive, but the long-term persistence of cork oak is endangered in these ecosystems, with health of poor cork oak and low natural regeneration rates being ...

Identifying the productivity, economic feasibility and greenhouse gas (GHG) emissions impact is the premise of our study on using marginal land for bioenergy production in Canada. The area of marginal land available was identified by inter ...

Abstract:
... Complex couplings and feedback among climate, fire, and herbivory drive short- and long-term patterns of land cover change (LCC) in savanna ecosystems. However, understanding of spatial and temporal LCC patterns in these environments is limited, particularly for semi-arid regions transitional between arid and more mesic climates. Here, we use post-classification analysis of Landsat TM (1990), ETM+ ...

Abstract:
... Understanding temporal and spatial dimensions of land cover dynamics is a critical factor to link ecosystem transformation to land and environmental management. The trajectory of land cover change is not a simple difference between two conditions, but a continuous process. Therefore, there is a need to integrate multiple time periods to identify slow and rapid transformations over time. We mapped ...

Positive economic but negative environmental impacts of Robinia result in conflicts of interest between nature conservation, forestry, urban landscaping, beekeepers and the public when defining management priorities. Because current legislation will determine the future distribu ...

From a review of 184 studies on bamboo biomass for 70 species (22 genera) we estimate plausible ranges for above-ground carbon (AGC) biomass (16–128MgC/ha), below-ground carbon (BGC) biomass (8–64MgC/ha), soil organic carbon (SOC; 70–200MgC/ha), and total ecosystem carbon (TEC; 94–392MgC/ha). The total ecosystem carbon range is below that for most types of forests, on par with that of rubber plant ...
