Given the outstanding global progress of research on the hydraulic pathway in plants, and its important role as an indicator of plant mortality risk, we reviewed: (1) the adaptive basis of hydraulic traits and their importance for overall plant function; (2) the number of primary scientific articles on plant hydraulics that have been produced in Mexico in the last 40 years, (3) research related to specific environments in Mexico, and (4) the possible applications of plant hydraulics to natural resource management. Our systematic review included 83 articles. The number of publications per year steadily increased over time, reaching its maximum in 2021. Veracruz and Yucatán are the states where the majority of scientific articles on plant hydraulics have been produced, but for most states less than two publications on this subject appeared in ca. 40 years, and none was found for Oaxaca and Chiapas, the most biodiverse states. In plant hydraulics, the most studied biome in Mexico was the tropical dry forest, followed by crops; trees were the most studied growth-form, followed by herbaceous crops and epiphytes. We point to the need of enhancing research in the interface between plant hydraulic function and remote sensing, as well as developing applications in adaptive forest management and ecological restoration. We hope that this review may ignite a national collaborative effort to quantify critical traits that could inform the hydraulic functioning of Mexican ecosystems, particularly in the underrepresented and highly diverse states of Mexico. © 2022 Sociedad Botanica de Mexico, A.C.

We present the most complete molecular phylogeny to date of the Pithecellobium clade of subfamily Caesalpinioideae. This neotropical group was informally recognised (as the Pithecellobium alliance) at the end of the 20th century by Barneby and Grimes (1996) and includes five genera and 33 species distributed from the southern United States and Caribbean Islands to north-eastern South America. Our aims were to further test the monophyly of the group and its genera and to identify sister group relationships within and amongst the genera. A phylogenetic analysis of nuclear ribosomal DNA sequences (ITS and ETS) was performed. The results provide further support for the monophyly of the Pithecellobium clade. The genera Ebenopsis, Pithecellobium and Sphinga were strongly supported as monophyletic. Havardia and Painteria were found to be non-monophyletic, prompting their re-circumscriptions and the description of two new genera: Gretheria and Ricoa. New combinations are made for the three species transferred to the new genera. © Iván Tamayo-Cen et al.

A Novel Technique for Classifying Bird Damage to Rapeseed Plants Based on a Deep Learning Algorithm.

Ali Mirzazadeh Afshin Azizi Yousef Abbaspour_Gilandeh José Luis Hernández-Hernández Mario Hernández Hernández Iván Gallardo Bernal (2021, [Artículo])

Estimation of crop damage plays a vital role in the management of fields in the agricultura sector. An accurate measure of it provides key guidance to support agricultural decision-making systems. The objective of the study was to propose a novel technique for classifying damaged crops based on a state-of-the-art deep learning algorithm. To this end, a dataset of rapeseed field images was gathered from the field after birds¿ attacks. The dataset consisted of three classes including undamaged, partially damaged, and fully damaged crops. Vgg16 and Res-Net50 as pre-trained deep convolutional neural networks were used to classify these classes. The overall classification accuracy reached 93.7% and 98.2% for the Vgg16 and the ResNet50 algorithms, respectively. The results indicated that a deep neural network has a high ability in distinguishing and categorizing different image-based datasets of rapeseed. The findings also revealed a great potential of Deep learning-based models to classify other damaged crops.

Addressing agricultural labour issues is key to biodiversity-smart farming

Thomas Daum Frédéric Baudron Matin Qaim Ingo Grass (2023, [Artículo])

There is an urgent need for agricultural development strategies that reconcile agricultural production and biodiversity conservation. This is especially true in the Global South where population growth is rapid and much of the world's remaining biodiversity is located. Combining conceptual thoughts with empirical insights from case studies in Indonesia and Ethiopia, we argue that such strategies will have to pay more attention to agricultural labour dynamics. Farmers have a strong motivation to reduce the heavy toil associated with farming by adopting technologies that save labour but can negatively affect biodiversity. Labour constraints can also prevent farmers from adopting technologies that improve biodiversity but increase labour intensity. Without explicitly accounting for labour issues, conservation efforts can hardly be successful. We hence highlight the need for biodiversity-smart agriculture, that is farming practices or systems that reconcile biodiversity with land and labour productivity. Our empirical insights suggest that technological and institutional options to reconcile farmers' socio-economic goals and biodiversity conservation exist but that more needs to be done to implement such options at scale.

There is speculation about moon phases influencing animal reproductive performance. A study was carried out to shed light on the influence of moon phases on estrus presentation, pregnancy rate, calving presentation, and offspring sex in cows from the Mexican dry tropical region. The reproductive data of 580 crossbred cows from 2010 to 2021 was organized according to reproductive events (estrus presentation, gestation, calving presentation, and offspring sex) occurrence during moon phases (new moon, first quarter, full moon, and last quarter). The data were analyzed by Chi-squared test and logistic regression. The full moon reduced the estrus presentation (p0.05). It is concluded that the full moon reduces estrus presentation in crossbred cows. Moon phases do not influence the gestation, calving presentation, and offspring sex.

Noteworthy record of the kit fox (Vulpes macrotis) and its relation to physiographic characteristics in Baja California, Mexico

SARAHI SANDOVAL ESPINOZA MARIANA DELGADO FERNANDEZ Jonathan Gabriel Escobar Flores (2017, [Artículo])

"The kit fox (Vulpes macrotis) lives in sandy and shallow soils of the Pacific coastal plains and the ecoregion of San Felipe desert. The reports of this species are scarce and in Mexico it is listed as a threatened species. The populations of V. macrotis tend to decrease due to the change in the habitat to agricultural land, which has been one of the causes of the disappearance of kit fox populations in Mexico. As part of the project “Characterisation of water bodies in Sierra Santa Isabel, Baja California”, 12 camera traps were placed in six watering holes that are visited by wildlife from January to August 2015. Digital terrain elevation models were used to describe three variables: roughness, slope inclination and orientation; these variables are essential for the kit fox to build its burrows, catch its preys and escape from predators. The analyses were also carried out in localities where this carnivore had previously been recorded in Baja California. An analysis of variance was used to determine the existence of similarities or differences between the topographical characteristics of the historical localities and the new record. The first photographic record of the kit fox was obtained in one of the watering holes located within the Valle de los Cirios Flora and Fauna Protection Area. The analyses of variance confirmed that there are no significant differences between roughness (F(4, 780) = 0.11, P > 0.05), slope inclination (F(4, 1275) = 0.319, P > 0.05) and orientation (F(4, 15) = 0.41, P > 0.05), between the historical localities and the site where the new record was obtained. Other carnivores were also recorded in the watering hole, such as the cougar (Puma concolor), bobcat (Lynx rufus), coyote (Canis latrans) and gray fox (Urocyon cinereoargenteus). The presence of the kit fox is likely occasional in the watering hole, because the slopes are greater than 10 degrees and, therefore, these sites are unsuitable for the construction of burrows. However, flat sites with sandy substrates that empty into the Gulf of California occur at a distance of less than 5 km from the watering hole, which are therefore suitable to be inhabited by the kit fox. the analysis of topographic variables of the historical records coupled with camera traps jointly confirmed that the site with the new record has characteristics that are suitable for the kit fox."

"La zorra norteña (Vulpes macrotis) habita en los suelos arenosos y pocos profundos de las planicies costeras del pacifico y de la ecorregión del desierto de San Felipe. Los reportes de esta especie son escasos y en México esta enlistada como una especie amenazada. Las poblaciones de V. macrotis tienden a disminuir por la transformación del hábitat a tierras agrícolas, la cual ha sido una de las causantes de la extirpación de poblaciones de zorra norteña en México. Como parte del proyecto “Caracterización de los cuerpos de agua en Sierra Santa Isabel, Baja California”, se colocaron 12 cámaras trampa en seis aguajes que son visitados por la fauna silvestre de enero a agosto de 2015. Mediante modelos digitales de elevación del terreno se describieron tres variables: rugosidad, pendiente y orientación de las laderas, estas variables son esenciales para que la zorra norteña construya sus madrigueras, capture a sus presas y escape de sus depredadores. Los análisis también se realizaron en localidades que previamente se había registrado a este carnívoro en Baja California. Por medio de un análisis de varianza de una vía se determinó si existen similitudes o diferencias entre las características topográficas de las localidades históricas y el nuevo registro. En uno de los aguajes que se ubica dentro del Área de Protección de Flora y Fauna Valle de los Cirios, se obtuvo el primero registro fotográfico de la zorra norteña. Con los análisis de varianza se confirmó que no hay diferencias significativas entre la rugosidad (F(4, 780) = 0.11, P > 0.05), pendiente (F(4, 1275) = 0.319, P > 0.05) y orientación (F(4, 15) = 0.41, P > 0.05), entre las localidades históricas y el sitio donde se obtuvo el nuevo registro. En el aguaje también se registraron otro carnívoros, como el puma (Puma concolor), gato montés (Lynx rufus), coyote (Canis latrans) y zorra gris (Urocyon cinereoargenteus). La presencia de la zorra norteña posiblemente es ocasional en el aguaje, debido a que las pendientes en el lugar son mayores a 10 grados y por lo tanto estos sitios no son idóneos para la construcción de madrigueras. Sin embargo, a una distancia menor a 5 km del aguaje se encuentran sitios planos con sustratos arenosos que desembocan al Golfo de California, y por lo tanto son idóneos para que la zorra norteña sea residente de esos lugares..."

SOCIO-SPATIAL TRENDS: A GENERAL READING OF PUBLIC SPACE IN HOUSING DEVELOPMENTS

Mariel Organista Camacho Karen Estrella Martínez-Torres Claudia Rivera-Torres (2023, [Artículo, Artículo])

Human nature implies social interaction in diverse environments, where public space, seen as an essential mediator, becomes disconnected, impersonal, and deteriorated exterior spaces, coupled with a lack of interest in participation, inclusion, and personal development. Therefore, this research aimed to analyze the socio-spatial relationships in public spaces based on the inhabitant perception of two housing developments in Ensenada, Baja California, Mexico. This study used a mixed methodological approach to collect information by applying the following instruments: a questionnaire on public spaces, a series of in situ and aerial photographs, and field observations. A total of 196 surveys were applied from 2016 to 2019; the morphological, typological, and functional characteristics of the public space were also observed. The results evidenced an imminent need to carry out their daily activities on a smaller scale and intensity within the housing complex with a level of spatial satisfaction within a scale of 6.37/10. In this regard, the inhabitants reported a higher attendance of the public space use in Los Encinos in contrast to Villas (62.6% and 39.3%, respectively), even though the travel times were shorter in Villas. Regarding the public space usefulness, both cases weighted spatial understanding followed by access ease to the housing complex with a Pearson correlation coefficient equal to or greater than 0.47. In this sense, spatial relations showed dispersion, disorganization, and fragmentation from the ephemeral. In contrast, social relations were considered impersonal, hurried, and of convenience, subordinated to the conditions of the environment, being that personal well-being is built from relations with the exterior and with the collective itself.
