“…Most of the fires in this A. religiosa forest occurred in spring (92.8%), which is consistent with the seasonality reported in P. hartwegii forest in this same region of the Sierra Norte de Puebla, where 92% of the fires were recorded in the beginning of the growing season [47]. A similarly pattern dominated by spring fires has also been reported in previous studies in P. hartwegii forests, in Pico de Orizaba [48], Sierra Norte de Puebla [47] and Cofre de Perote [49], all of which are located within the TMVB region. In the Sierra Norte de Puebla, spring fires in A. religiosa forests coincides with the period of least rainfall and highest temperatures of the year [37].…”

The oyamel forests, as Abies dominated forests are commonly known as, register their largest distribution (95% of their population) along the Trans-Mexican Volcanic Belt (TMVB). Although efforts have been made to study these forests with various approaches, dendrochronology-based studies have been limited, particularly in pure Abies forests in this region. The objective of this study was to reconstruct fire regimes in an Abies religiosa forest in the Sierra Norte in the state of Puebla, Mexico. Within an area of 50-ha, we collected 40 fire-scar samples, which were processed and analyzed using dendrochronological techniques to identify 153 fire scars. The fire history was reconstructed for a period of 118 years (1896–2013), with low severity surface fires occurring mainly during in the spring (92.8%) and summer (7.2%). Over the past century, fires were frequent, with an mean fire interval (MFI) and Weibull median probability of (WMPI) of five years when considering all fire scars and less than 10 years for fires covering larger areas (fires recorded by ≥25% of samples). Extensive fires were synchronized with drought conditions based on Ring Width Indexes, Palmer Drought Severity Index (PDSI) and El Niño Southern Oscillation (ENSO). After 1983, we observed a change in fire frequencies attributed to regulated management. Longer fire intervals within the last several decades are likely leading to increased fuel accumulations and could potentially result in more severe fires in the future, threatening the sustainability of these forests. Based on our finding, we recommend management actions (silvicultural or prescribed fire) to reduce fuels and the risk of severe fires, particularly in the face of climatic changes.

“…However, populations of L. rufus could be at risk because of hunting and illegal trade, despite being on Appendix I and II of CITES (Kelly et al, 2016). In PONP they are also at risk of forest fires (with frequent records from 1876 to 2011, particularly in the spring [97 %]), and decreasing rainfall (Cerano-Paredes et al, 2016). There is also considerable habitat loss due to clandestine logging and over use/ harvesting of forest resources (Ávila et al, 1994).…”

Temporal overlap in the activity of Lynx rufus and Canis latrans and their potential prey in the Pico de Orizaba National Park, Mexico. Species of the same trophic guild are thought to coexist through their differential use of resources, including food, space and time. Time understood as the pattern of activity is highly dynamic. Fourteen camera-traps were set up in the Pico de Orizaba National Park and active for 12 months. Frequency histograms were used to analyze their activity patterns (AP) and a coefficient of overlap (Δ) was used to determine the temporal overlap between two predators, Lynx rufus and Canis latrans, and the predators and their potential prey. A sampling effort of 5,110 traps/night obtained 217 independent records of L. rufus (45), C. latrans (27) and eight potential prey species (145). The predators were cathemeral and four potential prey mainly lagomorphs and rodents were nocturnal. The temporal overlap between the predators Δ = 0.80, and the highest overlap between predators and prey were for C. latrans and rodents (Δ = 0.80), and L. rufus and lagomorphs (Δ = 0.58), with differences between the degree of overlap in dry and rainy seasons. The cathemeral habits of the predators likely increase their likelihood of hunting success, particularly for prey with variable activity patterns. The APs support information on dietary breadth and the differential use of resources and temporal differences as strategies for coexisting predators, continually adapting to a highly dynamic and changing environment. ResumenSuperposición temporal de la actividad de Lynx rufus y Canis latrans y sus presas potenciales en el Parque Nacional Pico de Orizaba, en México. Se cree que el uso diferencial de los recursos, en especial del espacio, la comida y el tiempo, permite la coexistencia de especies del mismo gremio trófico. El tiempo entendido como el patrón de actividad es altamente dinámico. En el Parque Nacional Pico de Orizaba se instalaron 14 cámarastrampa que estuvieron activas durante 12 meses. Se analizaron los patrones de actividad (PA) de las especies mediante histogramas de frecuencia y se calculó el índice de solapamiento (Δ) para determinar la superposición temporal entre dos depredadores, Lynx rufus y Canis latrans y entre los depredadores y sus presas potenciales. Con un esfuerzo de muestreo de 5.110 noches/trampa se obtuvieron 217 registros independientes de L. rufus (45), C. latrans (27) y de ocho especies de presas potenciales (145). Los depredadores fueron catamerales y cuatro presas, nocturnas, principalmente lagomorfos y roedores. La superposición temporal entre ambos depredadores fue ∆ = 0,80 y entre estos y sus presas, los valores más altos se encontraron entre C. latrans y los roedores (∆ = 0,80) y entre L. rufus y los lagomorfos (∆ = 0,58), con variaciones entre la estación seca y la de lluvias. Al ser de hábitos catamerales, los depredadores tienen más posibilidades de cazar más presas, en especial las que tienen patrones de actividad variables. Los PA validan la información sobre la varied...

“…In México, the Mexican Mountain Pine (Pinus hartwegii Lindl. ), a tree species sensitive to climate [27][28][29][30], dominates the high-elevation forests but recent studies have found that the natural habitat of this species is at risk due to climate change [31][32][33]. Recently, Correa-Díaz, et al [34] found a declining radial growth trend in mature P. hartwegii trees at Tláloc Mountain (TLA), starting around the middle twentieth century.…”

Ongoing climate variability strongly affects high-elevation forests, influencing the wood formation process (e.g., xylogenesis). Furthermore, spatio-temporal studies to establish links of wood properties and tree performance are needed. Using linear mixed-effects models, empirical cumulative distribution functions, and spatial analysis, we explore time trends and space connections of wood density of Pinus hartwegii Lindl. to remotely sensed variables (Moderate Resolution Imaging Spectro-radiometer MODIS-derived) in two high-elevation forests in México, Tláloc (TLA) and Jocotitlán (JOC) Mountains. Results indicated that elevation and cambial age effects are important factors explaining wood density variation. Minimum earlywood—MID, average—AVE, and maximum latewood density—MXD were statistically similar between mountains (p > 0.05), but TLA showed a significant increase in MID over time with higher values after 1950. Wood density values and spatial correlations were site-dependent with TLA exhibiting the highest correlations between MXD and the Normalized Difference Vegetation Index (NDVI) of the spring season (r = 0.59, p < 0.05). Overall, correlations to remotely sensed information were positive with MXD, negative for MID and divergent for AVE. Historical temperature defines MID along the elevation gradient, while MXD was related to soil moisture only at low-elevation sites where soils are deeper. We found that two high-elevation forests, 115 km away from each other, with similar climate, soil, and vegetation, behaved differently regarding their xylogenesis, indicating the potential of using the link between wood micro-density and remotely sensed information to understand forest response to climate change effects.
