Grassland bird populations have declined more than any other group of bird species in North America. Some species such as the grasshopper (Ammodramus savannarum) and Baird’s sparrows (Ammodramus bairdii) are of particular conservation concern, since they have shown negative trends in their population over the last 50 years. Their winter ecology has only begun to be studied recently and information is limited. The purpose of this study is to achieve the morphometric characterization of these two grassland species during the wintering season. The study is conducted in the Rancho Santa Teresa located in Villa Hidalgo, Durango, Mexico and the Ecological reserve “El Uno”, located in Janos, Chihuahua, Mexico. During winter 2013-2014, 135 birds were captured;banded and zoometric measurements were taken such as total body weight, wing chord, tail length, culmen, and beak depth and width. Two indices of body condition (BCI) are also calculated. All measurements and indices are compared per species and per sex. Both species are sexed with molecular techniques, determining 20 females and 18 males for A. bairdii and 41 females and 56 males for A. savannarum. All variables are significant different between species (p < 0.05). Beak measurements are not significantly different when comparing birds of different sexes (same species), with the exception of beak width of A. bairdii (p < 0.05). Male’s weight, wing chord, tail length, as well as one of the body condition indices (BCI2) are significantly higher (p < 0.05) than females’ for both species. BCI1 shows significant differences (p < 0.05) between species and sexes in A. bairdii. The biometric data obtained in this study can be used as reference values wintering populations of both species.

去甲肾上腺素能神经元的丧失及其引起的脑去甲肾上腺素(NA)水平的降低与阿尔茨海默病(AD)的进展有关。这似乎主要是由于NA减少小胶质细胞活化的能力。我们以前观察到NA诱导神经元产生趋化因子Fractalkine/CX3CL1。小胶质细胞CX3CR1(CX3CL1的唯一受体)的激活会减少小胶质细胞的活化,已知这在很大程度上引起AD特征性的神经元损伤。因此,操控小胶质细胞中CX3CR1的产物可能转化为对CX3CL1抗炎作用的增强或抑制。为了确定小胶质细胞CX3CR1产物在AD中是否发生改变,以及NA是否可以控制这种改变,我们在5xFAD小鼠和人类AD脑样本中分析了CX3CR1的表达和合成。此外,我们分别在小胶质细胞培养物和小鼠中分析了NA及NA再摄取抑制剂瑞波西汀的作用。我们的结果表明,CX3CR1在AD大脑皮质中的产量增加,而给予瑞波西汀进一步增加了它的含量,并增强了小胶质对淀粉样β斑的反应性。然而,直接向原代大鼠小胶质细胞或人类HMC3细胞给予NA会抑制CX3CR1的产生,这表明小胶质细胞对NA的反应可能会在不存在产生CX3CL1的神经元或其他非小胶质外在因素的作用下发生改变。
