Comparative Evaluation of Follicular Flushing Frequency and Scraping Time During Ovum Pick‐Up in Mares: Effects on Oocyte Recovery Rate and Technical Considerations

Reproduction in Domestic Animals, Volume 61, Issue 2, February 2026.
ABSTRACT Transvaginal ultrasound‐guided follicular aspiration or ovum pick‐up (OPU) has become the standard technique for oocyte collection in mares for intracytoplasmic sperm injection (ICSI). Although repeated follicular flushes and wall scraping are commonly used to improve oocyte recovery rate (ORR), the relative contribution of each remains ...

Composición y estructura vegetal de fragmentos de bosque seco tropical en paisajes de ganadería extensiva bajo manejo silvopastoril y convencional en Córdoba, Colombia

Caldasia, 2019
La ganadería extensiva ha afectado significativamente la biodiversidad y conservación del bosque seco tropical (bs-T), hoy considerado el ecosistema más amenazado en las tierras bajas tropicales. Se analizó la composición florística, riqueza y estructura

Experimental Evidence That Blood Parasite Infection Affects Incubation Patterns in a Cavity‐Nesting Songbird

Integrative Zoology, Volume 21, Issue 1, Page 178-191, January 2026.
Chronic blood parasite infections in wild birds can affect their incubation behavior. In pied flycatchers, females with reduced parasite infections incubated for longer than control females. Despite behavioral changes, no immediate effects on fitness were observed.

Spatial, Temporal, and Host‐Specificity Patterns of Three Genera of Blood Coccidian Parasites in Two Syntopic Mediterranean Lizards

Integrative Zoology, Volume 21, Issue 1, Page 69-78, January 2026.
Our results indicated that the three genera of blood parasites found in the two species of lizards studied can exhibit distinct epidemiological patterns across microgeographic and temporal scales. ABSTRACT We investigated the phenological variation of three genera of blood parasites of lizards (Schellackia, Karyolysus, and Lankesterella) using samples ...

Ganadería, campesinado y producción de granos básicos: competencias por el uso de la tierra en México

Revista Mexicana de Ciencias Políticas y Sociales, 2019
Consideramos a la ganadería vacuna como una forma específica de apropiación del espacio rural productivo, tratando de esclarecer las determinantes externas e internas de su reciente expansión, especialmente en las áreas tropicales, y sus contradicciones ...

Compresion y analisis de imagenes por medio de algoritmos para la ganaderia de precision

, 2021
The problem that we want to solve in this project of the subject of Data Structures and Algorithms, is to decipher some images, which have in them animals, being more specific, bovine animals; in which it is necessary to identify if the animal is healthy, that is to say, if it is in good conditions to be taken into account in the process of selection ...

From Colonial Natures to Entangled Ecologies: Making Due and Relational Geographies of Indigenous Resurgence in the Chaco

Antipode, Volume 58, Issue 1, January 2026.
Abstract This paper offers an alternative reading of decolonial geographies by examining how people make due in the context of colonial natures. Drawing on collaborative ethnographic research, we illustrate how everyday acts of reclaiming ancestral lands serve as practices of resistance that foment Enxet and Sanapaná resurgence in Paraguay's Chaco.

Strong Variation in Land‐Use Change Impacts on Tropical Avian Phylogenetic Diversity Between Ecoregions Highlights the Need to Sample Large Spatial Scales

Global Change Biology, Volume 32, Issue 1, January 2026.
Forest conversion for agriculture is a major cause of biodiversity loss in the tropics, but its impacts depend on how broadly they are measured. Using data from across Colombia, one of the most biodiverse countries in the world, we examined how deforestation for cattle farming affects the evolutionary history of bird species.

Wetland location and captive breeding influence trans‐Mediterranean movements in the endangered Marbled Duck (Marmaronetta angustirostris)

Ibis, Volume 168, Issue 1, Page 245-258, January 2026.
Waterbirds distributed in semi‐arid and arid regions seem to have adapted their behaviour to the availability and seasonality of wetlands, increasing their mobility range. The Marbled Duck Marmaronetta angustirostris is a threatened waterbird that shows trans‐Mediterranean movements but these are poorly known.
