New aspects of boar sperm encapsulation

, 2011
The study takes into account the main steps and techniques for boar semen encapsulation, to optimize the instrumental insemination interventions. The use of cheap, biocompatible polymers as alginate can assure a regular, constant release of spermatozoa ...

Animal‐Mediated Dispersal and Clonal Growth Drive Prunus cerasus Invasion in Andean Temperate Forest

Integrative Zoology, EarlyView.
Prunus cerasus reproduces by clonality and by seed dispersal and germination. P. cerasus is invading Patagonian protected areas. The relative relevance of germination and clonal reproduction changes along the time of P. cerasus arrival at a site. Seed dispersal by foxes is primarily responsible for the spread of P. cerasus to new areas.

A Wildlife Multi‐Modal Recognition Method Based on Infrared Camera Images Using MWAC

Integrative Zoology, EarlyView.
A multimodal wild wildlife classification model MWAC consists of two parts:(1) Wavelet KAN module (WDS‐KAN) for image feature extraction, and (2) Label Correlated Text Extraction module (LC‐BERT) for text feature extraction. ABSTRACT Nowadays, infrared camera technology has become an important tool for large‐scale monitoring and assessment of wildlife ...

De‐Dollarization Is a Plausible Outcome of the New Washington Consensus

Global Policy, EarlyView.
ABSTRACT A trend towards de‐dollarization of the global economy in which the US dollar ceases to be used as the world's reserve currency for international transactions confronts some of the existing structures of international economic law, built upon the rules set out by US‐led organizations like the WTO, the IMF, and the World Bank. This article will

Assessing Spatiotemporal Side Effects of Diversionary Feeding on Mesopredators

Animal Conservation, EarlyView.
We tested whether diversionary feeding alters the space use, aggregation, or activity patterns of mesopredators using a treatment‐control design with camera traps. Although both species frequently used feeding stations, diversionary feeding did not significantly affect their spatial distribution, aggregation, or temporal behaviour.

Weekend Overload: Day‐to‐Day Fluctuations of Outdoor Recreation Affect Wild Mammals' Space‐Use in a Popular Forest Reserve Near Florence, Italy

Animal Conservation, EarlyView.
In an urban‐adjacent forested area, we investigated the spatial and temporal distribution of the wild mammal community in relation to day‐to‐day fluctuations of human presence occurring between working days and weekends. We deployed 52 camera‐traps systematically within an EU Natura 2000 area located within the metropolitan area of Florence, central ...

Testing the Assumption That Tiger Population Recovery Increases Conflict Across Their Range

Animal Conservation, EarlyView.
Tiger population recovery is widely assumed to increase conflict with people, yet this assumption has rarely been examined using range‐wide evidence. Analysing data from ten tiger range countries between 2010 and 2025, we found no consistent evidence that tiger population recovery is associated with increased conflict incidents.

Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

Andrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Lactate‐Responsive Glycogen Dynamics Are Associated With Bull Sperm Motility and Fertilization Under Glucose‐Limited Conditions

Andrology, EarlyView.
ABSTRACT Background Mammalian sperm need to undergo hyperactivation, capacitation, and acrosome reaction to achieve fertilization competence. However, the female reproductive tract presents contrasting metabolic environments. The uterus is glucose‐rich, and the oviduct is lactate‐rich and glucose‐limited.

Cryopreservation Disrupts TRIM21‐Mediated AKAP3 Ubiquitination and Triggers Stress Granule Formation in Human Sperm

Andrology, EarlyView.
ABSTRACT Background Sperm cryopreservation causes cryodamage, but the roles of posttranslational modifications (PTMs) and stress granules (SGs) in this process remain unclear. Objectives To investigate the molecular mechanism of cryodamage via the TRIM21–AKAP3 axis, PTMs, and SGs.
